Audi A8

Hello, now i'm talking about Audi A8. It was starting making in 1994, by replacing Audi V8 model.

Audi A8-is a four-door, full-size, luxury sedan car manufactured and marketed by the German automaker Audi since 1994. Succeeding the Audi V8, and now in its third generation, the A8 has been offered with both front- or permanent all-wheel drive and in short- and long-wheelbase variants. The first two generations employed the Volkswagen Group D platform, with the current generation deriving the MLB platform. After the original model's 1994 release, Audi released the second generation in late 2002, and the third and current iteration in late 2009.

Notable for being the first mass-market car with an aluminium chassis, all A8 models have utilised this construction method co-developed with Alcoa and marketed as the Audi Space Frame.

A mechanically-upgraded, high-performance version of the A8 debuted in 1996 as the Audi S8. Produced exclusively at Audi's Neckarsulm plant, unlike the donor A8 model, the S8 has been available only in short-wheelbase form and is fitted standard with Audi's quattro all-wheel drive system.

Audi A8 D2:

The Audi A8 (Typ 4D) was presented in February 1994 and debuted at the 1994 Geneva Auto Show in March, with full-scale factory production commencing June 1994, although it was not until October 1996, for the 1997 model year that it became available in North America. Unlike its predecessor, the Audi V8 model, which was built on an existing steel platform, the A8 debuted on the then-new Volkswagen Group D2 platform, an all aluminium monocoque, marketed as the "Audi Space Frame" (ASF), which helped to reduce weight and preserve structural rigidity. The saloon/sedan was offered in both the A8 (standard wheelbase), and the A8 L extended or long-wheelbase (LWB) version. The A8 L adds 5 inches (127 mm) of rear legroom. Updates to the car in 1997 included the addition of six interior airbags.

For 1997, the new A8 was available with either front-wheel drive (FWD), or the Torsen-based quattro permanent four-wheel drive. The FWD models are powered by a 2.8-litre V6 engine, producing 142 kw (193 PS; 190 bhp), and 3.7-litre V8 engine producing 171.5 kilowatts (233 PS; 230 bhp), while the quattro received a 4.2-litre V8 producing 220 kilowatts (299 PS; 295 bhp).

The A8 is available with standard luxury amenities, including dual-zone climate control, wood and leather interior trim, 14-way power and heated seats, and an enhanced Bose audio system.

In 1999, Audi's flagship received new colours, and restructuring of option packages. The North American "warm weather package" added a solar sunroof which allows the interior ventilation fans to run, keeping the interior cool while the car is parked with the engine turned off. Changes to all models included a larger passenger-side mirror, and a first aid kit located in the rear centre armrest.

In 1999 for the 2000 model year saw a minor front-end restyle, with new, larger, clear headlights, a revised grille, and lower front valance with standard projection fog lamps. On the interior, the seats received a new, horizontal stitch pattern. Also, the 3.7-litre V8 FWD model was dropped, leaving the 2.8 V6 model and the long-wheelbase and short-wheelbase 4.2-litre quattro. These restyled cars also featured revised external door handles and an integrated radio antenna. For 2000, the North American A8 line-up was expanded to include the A8 L.

For 2001, A8 received side curtain airbags. In 2001, Audi introduced its new W12 engine, a compact 6.0-litre unit developed by effectively mating two VR6 engines together at the crankshaft. The engine quickly became available in the A8, though only to European and Asian customers. From its introduction through its discontinuation in 2003, only 750 of the D2 "W12" models were produced. 2001 also marked the debut of the high-performance S8 variant in North American markets.

In 2002, the A8 L received standard xenon high-intensity discharge lamp (HID) headlights, and a heated steering wheel. A tyre pressure monitoring system (TPMS), an updated Symphony II stereo, and new exterior colours were also added. For 2002, all A8 variants received a trunk/boot interior release lever to facilitate escape in the event an individual became trapped within.

Factory production of this generation ceased at Number 105,092 in August 4, 2002.

The picture is of my Audi A8, which has 3.3 V8 TDI common rail diesel Engine with 2 turbochargers and automatic tiptronic gearbox.

Audi A8 D3:

The second-generation Audi A8 (Typ 4E) built on the Volkswagen Group D3 platform was unveiled via press release in July 2002 and introduced in November 2002 in Europe and in June 2003 in the United States. The model was longer than the previous generation, with room for four or five large adult occupants in the cabin, depending on rear seat configuration. The D3 development program began in 1996, with the design process commencing in Ingolstadt in 1997. The whole Audi design studio based in Ingolstadt first contributed sketch proposals, from which numerous different themes emerged. Six of them were developed into full size clay models and worked up in a traditional manner adjacent to full size tape drawings. At least three one quarter scale models were produced to explore other design variations.

The six full size exterior clay models were reduced to two in late 1998 and these continued to be refined in parallel for a year. At the end of 1999 the final theme selection was made, by Miklós Kovács and Imre Hasanic the main contributing designers. This lengthy development time was in part due to the body being made from aluminium, a material less able to take the small radii of sharp feature lines such as those on the (steel bodied) A4 (B6) designed in 1998.

In parallel to the exterior design development the interior design was progressed with a total of four full size models produced and the production car's horizontally themed instrument panel design dominant from early on, with Norbert Schneider, Mark Bergold and Enzo Rothfuss the main contributing designers.

Grouping major controls nearer the driver for a more driver focused identity whilst creating a more airy and spacious feel were early priorities for the interior design team was headed by Jurgen Albamonte. This was in part facilitated by the MMI interface, designed by Jurgen Schröder, that pioneered on the D3 A8 after the Avantissimo concept car preview, and also by class leading colour and trim from Barbara Krömeke and Melinda Jenkins.

Under the supervision of Dany Garand, during the first half of 2000 exterior and interior clay models were digitized and developed using digital design tools in a supporting, not leading, capacity. The D3 final production design was later frozen in the summer of 2000 for an August 2002 start of production.

As with the previous version, two body variants of the second generation A8 are offered, the A8 (standard, or short wheelbase), and the long-wheelbase (LWB) A8 L. The A8 L adds 120 mm (4.7 inches) to the rear legroom and 11 mm (0.43 in) to the overall height of the car.

In 2005, new internal combustion engines became available. For European and Asian market customers, the entry-level 3.0-litre V6 engine was replaced with a new 3.2-litre unit featuring Fuel Stratified Injection (FSI), which it shared with the Audi B7 A4 and Audi C6 A6. The top-of-the-line W12 version debuted that year. The advantage of the W12 engine layout is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 could only have a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, Audi's 6.0-litre W12 is actually slightly smaller by overall dimensions than the 4.2-litre V8.

In addition to the added power trains, Audi restyled the D3 platform A8 range slightly in 2005, giving all variants a taller, wider trapezoidal single-frame grille. The top-of-the-line W12 engined W12 version was the first model to be equipped with this grille; V8 engined models were fitted with the new grille the following year.

The D3 generation A8 introduced the 235 kW (315 hp) 4.2-litre Turbocharged Direct Injection (TDI) V8 engine (subsequently uprated to 240 kW (322 hp)). The engine uses two turbochargers and two intercoolers, with each turbocharger functioning exclusively for one bank of four cylinders.

From 2005 or 2006 Audi started offering the optional 1,000-watt 14-channel ICEpower Bang & Olufsen sound system.

From September 2007 for the 2008 model year, the A8 received a facelift and also received new electronic safety systems. "Audi Side Assist" detects cars in the A8's blind spots. "Audi Lane Assist" helps when the driver attempts to change lanes without signalling first.

From this model, Audi has started putting 5.2 V10 engine from Lamborghini.

Audi A8 D4:

The third-generation Audi A8 (Typ 4H) is based on the Volkswagen Group MLB platform, but retains the Audi Space Frame aluminium construction of the previous A8, making it the lightest all-wheel drive car in the full-size luxury segment, while also giving it best-in-class fuel economy. The quattro all-wheel drive system splits torque with a default bias of 40 percent front and 60 percent rear.

The vehicle was unveiled in Design Miami 2009 on 30 November 2009., followed by 2010 North American International Auto Show.

Early models include A8 4.2 FSI quattro (372PS), A8 3.0 TDI quattro (250PS), A8 4.2 TDI quattro (350PS). A8 3.0 TDI (204PS) was added later.

Initial internal combustion engine options comprise 4.2-litre Fuel Stratified Injection (FSI) petrol and Turbocharged Direct Injection (TDI) diesel V8s, with 273 kW (366 hp) and 258 kW (346 hp) respectively. A 3.0-litre V6 TDI with either 184 kilowatts (247 hp) or 150 kilowatts (201 hp) will be available later. A 6.3-litre W12 engine only for the long wheelbase model was made available in 2010, and compared to its predecessor it has a larger displacement and direct fuel injection. All engines are mated to the new eight-speed ZF 8HP automatic transmission. Although other Audi vehicles such as the 2010 Audi S4 and 2011 Audi A7 had switched from the 4.2L V8 to the 3.0L supercharged V6, the Audi A8 retained a higher-output 4.2L V8 as the base engine for the 2011 and 2012 model years in North America.

Taiwan models went on sale in 2010-11-11. Early models include 3.0 TFSI quattro (290PS).

Audi A6

Hello, now i'm talking about Audi A6. It was started making in 1994, replacing audi 100 C4 model.

Audi A6 C4:

Audi's mid-size car was previously named the Audi 100 (or Audi 5000 in the United States), and was released in three successive generations (Audi C1, Audi C2 and Audi C3). In 1994, the latest generation (C4) of the Audi 100 was facelifted and re-badged as the Audi A6, to fit in with Audi's new alphanumeric nomenclature (as the full-size A8 had just been introduced). The exterior was changed only slightly from the "C4" Audi 100 – new front and rear lights, new radiator grille, similarly with chassis and engine and transmission choices. The United Kingdom was the first market to receive the A6, as stock of RHD Audi 100s had run out before expected, and before the rest of mainland Europe.

The new engines for the A6 were 1.8-litre 20v inline four-cylinder, and 2.8-litre 30v V6 petrol engines, with the 2.3-litre inline five engine being dropped on most markets. For the diesel engines, an inline four 1.9 Turbocharged Direct Injection (TDI), and the inline five (R5) 2.5 TDI (103 kW (140 PS; 138 bhp)) were available.

Until 1997, the A6 came with several different engines, two of them turbodiesel, and most of them available with Audi's Torsen-based quattro permanent four-wheel drive system. The A6 was available with saloon and Avant bodies.

Audi A6 C5:

In February 1997, the introduction of a new A6 (Typ 4B), based on a new design automobile platform – the Volkswagen Group C5 platform, with a new range of internal combustion engines was announced and appeared in March at the 1997 Geneva Motor Show. This new A6 moved up a notch in quality, and was marketed in the same categories as the BMW 5-Series and the Mercedes-Benz E-Class. The redesigned body presented a modern design, with a fastback styling which set the trend for the Audi lineup, and gave the relatively large saloon an aerodynamic shell with a low coefficient of drag of 0.28.

In 2000 and 2001, the "C5" A6 was on Car and Driver magazine's Ten Best list. This new A6 was available with a wide range of engines and configurations. The 30-valve 2.4- and 2.8-litre V6 engines represented the bulk of the A6's development programme, with a multitude of other engine configurations available throughout the globe. As an alternative to the manual transmission, a five-speed tiptronic automatic transmission was also available.

The C5 saloon variant arrived in mid-1997 in Europe, late 1997 in North America and Australia, and the Avant in 1998. In Canada, there was no Avant (Audi's name for an estate/wagon) available at all in 1998 – Audi dropped the C4 Avant at the end of the 1997 model year, and jumped straight to the C5 Avant in 1998 in conjunction with its release in the US. As a result of complying with FMVSS, the North American models were equipped with front and rear bumpers that protruded several inches further than their European counterparts, with modified brackets and bumper suspension assemblies as result, and child-seat tethers for occupant safety. In compliance with Canadian law, Canadian models received daytime running lights as standard equipment. North American C5 A6 models received the 2.8-litre, 30-valve V6 engine, the 2.7-litre "biturbo" V6 (also found in the B5 platform S4), and the 4.2-litre 40-valve V8 petrol engines. The V8 models arrived with significantly altered exterior body panels, with slightly more flared wheel arches (fenders), revised headlamps and grille design (before being introduced in 2002 to all other A6 models), larger roadwheels (8Jx17-inch), larger brakes and Torsen-based quattro permanent four-wheel drive as standard.

In 2002, the A6 received a facelift, with revised headlight and grille design, exposed exhaust tips, and slight changes to accessory body moldings, and taillight colour from red to amber in North American models. A new host of engines were also introduced. The 1.8-litre engine was deleted and replaced by a 2.0-litre powerplant with 96 kw (131 PS; 129 bhp). The 1.9-litre Turbocharged Direct Injection (TDI) was tweaked to produce a maximum motive power output of 96 kilowatts (131 PS; 129 bhp), and 310 newton metres (229 lbf·ft) of torque, receiving a six-speed manual gearbox in the process. The 2.4-litre V6 gained an extra 5 hp and better balancing, and the 2.8-litre V6 engine was replaced by a 3.0-litre engine with 162 kilowatts (220 PS; 217 bhp). The turbocharged 2.7-litre was revised, resulting in 184 kilowatts (250 PS; 247 bhp) and 330 newton metres (243 lbf·ft), controlled by standard quattro. The V6 diesel was also slightly modified resulting in 120 kilowatts (163 PS; 161 bhp) (after the second modification) and 350 newton metres (258 lbf·ft). A new more powerful V6 diesel was also introduced with 132 kilowatts (179 PS; 177 bhp) and 370 newton metres (273 lbf·ft). The 4.2-litre V8 engine which arrived in 2001 remained unchanged.

Also new was the revolutionary multitronic continuously variable transmission, available in most front-wheel drive models. All models, except the 2.0-litre petrol and 1.9-litre TDI, were available with Audi's trademark four-wheel-drive system, quattro. A four-wheel-drive version of the Avant, with raised ground clearance and slightly altered styling was sold as the Audi allroad quattro, Audi's first crossover SUV.

Regarding this C5 generation, Car and Driver magazine stated, "It is one of the most winsome mid-sizers to meet pavement, with some of the nicest handling this side of a BMW. In 2000, the moderate performance of this otherwise excellent, 3.0-litre V6-powered, sedan was improved by the addition of two higher-performance versions: the 250 PS (180 kW; 250 hp), 2.7-litre bi-turbo V6 and the 300 PS (220 kW; 300 hp), 4.2-litre V8, both with Audi's quattro permanent four-wheel drive system. In mid-2003, major muscle came along in the limited-run RS6 – powered by a 450 PS (331 kW; 444 bhp), twin-turbo V8 engine – which immediately finished first in a C/D comparison test".

The second-generation A6 was on Car and Driver magazine's Ten Best list for 2000 and 2001. The updated 2005 A6 won the World Car of the Year award for 2005. In addition, the facelifted third-generation A6 3.0T won two Car and Driver "comparos" that pitted it against other sedans like the BMW 5-Series, the Mercedes E-Class, the Jaguar XF, and the Infinti M.

If you preparing to buy one of these, than one tip: don't buy 2.5 tdi 110 kw engine, beause it's rubbish, if you wan't 2.5 tdi engine than from 2000 is fixed engine version with 132 kw.

Audi A6 C6:

The Typ 4F A6 was released in 2004. Designed by Satoshi Wada in 2001, this model was visually an evolution of the C5, but was lengthened to 4,927 millimetres (194.0 in), and incorporates the new Audi trademark "single-frame grille". Like other contemporary Audis, the A6 had a "tornado line" that ran just below the sheetmetal's shoulders and joins the front and rear light clusters.

The C6 iteration of the A6 features more sophisticated technology. Most notable is the Multi Media Interface (MMI), which is a system controlling in-car entertainment, satellite navigation, climate control, car settings such as suspension configuration and optional electronic accessories through a central screen interface. This has the advantage of minimising the wealth of buttons normally found on a dashboard by replacing them with controls which operate multiple devices using the integrated display.

On the internal combustion engines, the new Fuel Stratified Injection (FSI) direct injection technology was introduced. Although the line of engines represents the same progression as the former model, all engines were new. The multitronic continuously variable transmission continues as an alternative for front-wheel drive models, alongside a new six-speed tiptronic automatic transmission available in the four-wheel drive models. Audi's "trademark" Torsen-based quattro permanent four-wheel drive is available in most of the lineup, and standard in the most powerful models. quattro is not available on the multitronic variants of the A6, but is available on the manual and tiptronic gear systems. Conversely the tiptronic system is not available on the front-wheel drive variants of the car. The six-speed manual gearbox is available with the 3.2-litre V6 engine, but not for the North American market.

The Avant arrived during the course of 2005. The A6 allroad quattro made its debut in 2006, and as before, is an off-road ready version of the Avant, available with either a 2.7-litre V6 or 3.0-litre V6 Turbocharged Direct Injection diesel engines, or a 3.2-litre V6 or 4.2-litre V8 petrol engine.

If you preparing to buy one of these, than be carefull with 2.0 tdi engine, it's really unreliable.

Audi A6 C7:

The fourth generation C7 series Audi A6 (internally designated Typ 4G) was launched in early 2011 for the European market and in other markets soon after. It is heavily influenced by the Audi A8 (D4), pulling elements from its exterior details. The A6 shares its interior, platform, and powertrain with the Audi A7 four door sedan, which had been released shortly before also in 2011. Compared to the A8 and A7, the A6 has the most aggressive front fascia and LED headlights. Design work began in 2006, with Jurgen Loffler's exterior design being chosen in 2008.

The new A6 increased its wheelbase by nearly 3 inches (76 mm) and its width by 0.7 inches (18 mm). The redesign also decreased the car's drag coefficient to 0.26 Cd.

European engine choices for the C7 include two petrol engines – a 2.8-litre FSI V6 with 204 horsepower (152 kW) and a 300 horsepower (224 kW), 3.0-litre supercharged FSI engine – and three diesel engines – a 2.0-litre inline four-cylinder and a 3.0-litre turbocharged diesel engine in three states of tune. The European A6 3.0 TFSI will have optional a seven-speed dual-clutch transmission and an air suspension, two features that will not be available on the United States model.

For North America, the Audi A6 3.0 TFSI quattro will be powered by a 3.0-litre supercharged V6 putting out 310 PS (228 kW; 306 hp) 325 lb·ft (441 N·m), the same engine carried over from the previous-generation A6 3.0 TFSI, but in a higher state of tune and mated to an eight-speed automatic transmission. For the United States but not the Canadian market, there will be an entry-level Audi A6 2.0 TFSI FrontTrak (front-wheel drive) with a 2.0-litre turbocharged inline-four, the same engine in the Audi A4 and Q5, but mated to the Multitronic CVT (continuous variable transmission).

The A6 features all the driver assistance systems from the A8, but adds a head-up display and Active Lane Assist. It also features an optional full-LED headlighting system.

Audi A4

 

Now i'm talking about Audi a4. It replaced audi 80 in 1994.

Audi A4 B5:

The first generation Audi A4 (known internally as the Typ 8D) debuted in October 1994, with production starting November 1994 and European sales commencing in January 1995 for the 1995 model year. North American sales later began in September 1995 for the 1996 model year. It was built on the Volkswagen Group B5 (PL45) platform, which it shared with the fourth generation Volkswagen Passat (B5, Typ 3B). It had a front-mounted longitudinal engine and front-wheel drive. Many variations of the A4 were also available with Audi's quattro four-wheel drive system. The A4 was initially introduced as a four-door saloon/sedan; the Avant (estate/wagon) was introduced in November 1995 and went on sale in February 1996.

Development began in 1988, with the first design sketches being created later that year. By 1991, an exterior design by Imre Hasanic was chosen and frozen for November 1994 production by 1992. The interior design was later finalized in 1992, with pilot production commencing in the first half of 1994. Development concluded in the third quarter of 1994, preceding November 1994 start of production.

A wide range of internal combustion engines were available in European markets, between 1.6 and 2.8 litres for petrol engines; and a 1.9 litre diesel engine available with Volkswagen Group's VE technology, capable of achieving a 90 PS (66 kW; 89 bhp) or 110 PS (81 kW; 108 bhp), although Audi's 2.8 litre V6 engine, carried over from the old 80/90 was the only engine option in North America until 1997.

The Audi A4 was the first model in the Volkswagen Group to feature the new 1.8 litre 20v engine with five valves per cylinder, based on the unit Audi Sport had developed for their Supertouring race car. A turbocharged version produced 150 PS (110 kW; 148 bhp) and 210 newton metres (155 lb·ft) torque. This technology was added to the V6 family of engines in 1996, starting with the 2.8 litre V6 30v, which now produced 193 PS (142 kW; 190 bhp).

Audi also debuted their new tiptronic automatic transmission on the B5 platform, based on the unit Porsche developed for their 964-generation 911. The transmission is a conventional automatic gearbox with a torque converter offering the driver fully automatic operation or manual selection of the gear ratios.

Audi A4 B6:

An all-new A4, internally designated Typ 8E, debuted on October 10, 2000, now riding on the all-new Volkswagen Group B6 (PL46) platform. The car's new styling (by Peter Schreyer in 1997) was a great success, inspired by the C5 (second-generation) Audi A6 introduced in 1997. The 1.6 litre base model powerplant remained unchanged, but most other petrol/gasoline engines received either displacement increases, or power upgrades. The 1.8 litre 20-valve Turbo was now available in two additional versions, with 150 PS (110 kW; 148 bhp) or 180 PS (132 kW; 178 bhp), this one with a standard six-speed manual gearbox, while the naturally aspirated 1.6 litre inline-four engine and 2.8 litre V6 were replaced by 2.0 litre, and all-aluminium alloy 3.0 litre units, still with five valves per cylinder, the most powerful of which was capable of 220 PS (162 kW; 217 bhp) and 300 newton metres (221 lb·ft) of torque. The 1.9 Turbocharged Direct Injection (TDI) engine was upgraded to 130 PS (96 kW; 128 bhp), with Pumpe Düse (Unit Injector) (PD) technology, and was now available with quattro permanent four-wheel drive, while the 2.5 V6 TDI high-end model was introduced with 180 PS (132 kW; 178 bhp) and standard quattro. This generation of quattro consists of default of 50:50 front to rear dynamic torque distribution. A Bosch ESP 5.7 Electronic Stability Programme (ESP) system, with Anti-lock Braking System (ABS), brake assist, and Electronic Brakeforce Distribution (EBD) were standard across the range.

The Avant was introduced in June 2001, arriving in European showrooms in September 2001.

For 2002, Audi upgraded power in the 1.8 Turbo engines to 163 PS (120 kW; 161 bhp) and 190 PS (140 kW; 187 bhp) – the 190 PS variant designated by a red 'T' on the boot lid, with both available with quattro, and in the 2.5 TDI intermediate version to 163 PS (120 kW; 161 bhp). A 2.0 engine with Fuel Stratified Injection (FSI) was also available. A year later, Audi reintroduced the S4, now powered by a 344 PS (253 kW; 339 bhp) 4.2 L V8 engine, as well as an A4 Cabriolet convertible variant (Typ 8H), finally replacing the 80-based Audi Cabriolet which had been discontinued in 1998. It included an electro-hydraulic operated roof, which lowered in under 30 seconds, and incorporated some styling changes which eventually found their way to the saloon version (such as body-coloured lower bumper and sill panels).

Audi also introduced a continuously variable transmission developed by LuK, named multitronic, which replaced the dated conventional automatic transmission on front-wheel drive models. The transmission won considerable praise from the automotive press, and is generally regarded as being the best of its type in the world, due to its light weight and promptness in response. This high strength chain driven CVT is made from highly durable metals and utilises a very high grade, purpose-designed fully synthetic lubricant. However there have been widespread complaints from consumers around the world that the transmission box is prone to electronic glitches as well as mechanical problems.

Borrowing from the Audi A6, the boot was redesigned to remove the extension of the top edge with a smoother fold line, and the rear light assemblies now formed part of the top line, these styling cues were eventually borrowed by other European as well as Asian manufacturers.

An "ultra sport package" named 'Ultra Sport' was introduced in the North American market shortly before the B6 was replaced by the B7. It included aluminium interior trim and door sills, "S line"  steering wheel, front and rear spoilers, side skirts, and quattro GmbH designed 18-inch RS4 alloy roadwheels.

Audi A4 B7:

Audi introduced a revised A4 in late 2004, with the internal designation of B7. However, this new range A4 still utilised the existing Volkswagen B6 (PL46) platform, a chassis derived from the outgoing B6, but enjoyed heavily revised steering settings, suspension geometry, new internal combustion engine ranges, navigation systems and chassis electronics (including a new advanced Bosch ESP 8.0 Electronic Stability Programme (ESP) system). The front grille assembly has changed to be a tall trapezoidal shape in the same manner as the C6 (third-generation) Audi A6.

Audi's internal platform nomenclature uses PL46 (passenger car longitudinal platform, size 4, generation 6) for both B6 and B7 chassis. The Typ 8E and Typ 8H internal designations are also carried over from the B6 A4 range, but now have an additional identifying suffix – 8EC for the saloon, 8ED for the Avant, and 8HE for the Cabriolet.

The engine lineup received many additions. The 2005 introduction of Fuel Stratified Injection (FSI) on the 2.0 TFSI and 3.2 V6 FSI petrol/gasoline engines, as well as other refinements, increased power output to 200 PS (147 kW; 197 bhp) and 255 PS (188 kW; 252 bhp), respectively. These engines both implement a four-valve per cylinder design. The prior 5-valve design was incompatible with the FSI direct injection system (due to the siting of the fuel injector, now discharging directly into the combustion chamber). The 2.0 Turbocharged Direct Injection (TDI) diesel engine now combines Pumpe Düse (Unit Injector) (PD) technology with 16 valves for the first time, while the larger 2.5 TDI V6 diesel was superseded by a 3.0 V6 TDI, offering a 204 PS (150 kW; 201 bhp) model during the year 2005 which was upgraded to a 233 PS (171 kW; 230 bhp) model in 2006. A 2.7 V6 TDI was added later.

Torsen T-2 based quattro permanent four-wheel drive remained available on most A4 models. Audi retired its 5-speed manual transmissions in favour of a new Getrag 6-speed. As before, multitronic continuously variable transmission (CVT), now with selectable 'seven-speeds', is available on front-wheel drive models, whilst a conventional ZF 6HP 6-speed tiptronic automatic transmission is available on the quattro four-wheel drive models.

In addition to the higher-performance Audi S4, which carried over the powertrain from the B6 S4 – Audi has reintroduced the ultra-high performance quattro GmbH developed Audi RS4 (RS for RennSport) to the lineup, for the first time on the saloon/sedan and Cabriolet body, and with a naturally aspirated, but high-revving 4.2 litre V8 FSI engine. Another notable inclusion on the RS4 is the latest generation Torsen T-3 quattro 4wd system, which uses a 'default' asymmetric 40:60 front-rear dynamic torque distribution bias. This new asymmetric centre differential was initially only available on the RS4, but was added a year later on the S4. The remainder of the B7 A4 range still utilised the T-2 50:50 default dynamic split centre diff.

A limited edition variant, developed by quattro GmbH, was first introduced in May 2005, named "Audi A4 DTM Edition". It was inspired from Audi's race cars of the 2004 Deutsche Tourenwagen Masters, and was reintroduced in 2006 as a regular option. The 2.0T FSI engine received revised software mapping to the ECU, which increased the output to 220 PS (162 kW; 217 bhp) and 300 N·m (221 lb·ft) of torque. It was available with front-wheel drive, or quattro four-wheel drive.

The B7 Cabriolet model arrived later than the other two body variants, with sales beginning in February 2006. New on the Cabriolet was an entry-level 2.0 TDI version, but to date, this is not being offered with the multitronic CVT gearbox.

In 2007 Audi introduced a limited edition of the B7 named the 'Special Edition', which built on the S-Line specification and also included the black optics pack, the RS4 style 8J X 18 ‘7-arm double spoke’ design alloy wheels, Two-tone Graphite/Black Volterra leather, 3-spoke sports leather/Alcantara multi-function steering wheel with gear knob and hand brake handle in Alcantara with silver stitching, Ventilated cross-drilled front disc-brakes, black tailpipes and black roof rails (avant model only). It also had a power increase of 20PS, giving an output of 220PS on the 2.0T model.

According to 2007 Swedish vehicle inspection data, the Audi A4 Avant with diesel engine is the most reliable vehicle available on the market, with vehicle inspection rejection rate of 0.0% in three year old category.

When its successor, the new B8 A4 range was introduced, the B7 series A4 was not destined for extinction – it was restyled and rebadged as the SEAT Exeo in 2008, with styling changes to the front and rear, also incorporating interior trim from the A4 Cabriolet. The entire Audi B7 A4 production line from Audis Ingolstadt plant was dismantled and sent to Volkswagen Group's related SEAT factory in Martorell, Spain.

Audi A4 B8:

Audi released the first official pictures of the B8 series A4 in August 2007, and unveiled the car to the public at the September 2007 Frankfurt Motor Show. Saloon/sedan and Avant (estate/wagon) models are offered. The Avant was unveiled to the public at the March 2008 Geneva Motor Show.

The B8 A4 is built on a variant of the Audi Modular Longitudinal Platform, a platform which is also used in the Audi A5 coupé. Whilst prior A4 chassis were limited in wheelbase due to the relationship between the engine, transmission and front axle, the MLP allows for a reduced front overhang, resulting in a greater wheelbase length without the same increase in overall length. This effectively redistributes the centre of gravity slightly rearwards, improving handling by better balancing vehicle mass between the front and rear axles. The estimated static front:rear weight ratio of the B8 A4 is approximately 55:45, depending on body style and engine. The relocation of the steering rack in front of the axle also improves handling over previous A4 platforms.

The B8 A4 has increased in wheelbase by 160 millimetres (6.3 in) and in length by 117 millimetres (4.6 in) over the prior B7, which has allowed for increased rear seating legroom. Although the overall dimensions have increased, the kerb weight has dropped some 10%. The boot (trunk) has also increased to 480 litres (17.0 cu ft) for the saloon (sedan) version. The A4 Avant will have a maximum capacity of 1,430 L (50.5 cu ft) with the rear seats folded down.

Reception has been mixed, with praise for the Audi A4's increased size, giving it best-in-class rear legroom and trunk space in the compact executive car segment. Its inline-4 2.0 TFSI engine, while efficient providing plenty of torque, was considered lacking and less refined compared to 6-cylinder engines of lighter rivals who posted faster acceleration times. However, the Audi S4 sports sedan has been well-received for its V6 3.0 TFSI engine's power and efficiency.

The B8 A4 was facelifted in early 2012.

During a model cycle changes are made to integrate new technologies and to keep the model competitive. These changes are referenced based on the model year (MY) of the car. In Australia, the B8 has undergone 2 revisions leading to three variants, the B8, B8 MY10  and B8 MY11.

Audi 100

Hello, i'm talking now about Audi 100.

Audi 100 are mid-sized executive cars manufactured in 1986-1994.

Audi 100 C1:

The Audi 100 was shown to the press on 26 November 1968. Its name originally denoting a power output of 100 PS (74 kW; 99 hp), the Audi 100 was the company's largest car since the revival of the Audi brand by Volkswagen in 1965. The C1 platform spawned several variants: the Audi 100 two- and four-door saloons, and the Audi 100 Coupé S, a stylish fastback coupé, which bore a remarkable resemblance to the Aston Martin DBS released a year earlier, especially at the rear end, including details such as the louvres behind the rear side windows and shape of the rear light clusters.

Audi followed up the introduction of the four-door saloon in November 1968 with a two-door saloon in October 1969 and the 100 Coupé S in autumn 1970. The cars' four-cylinder engines originally came in base 100 ( 80 PS or 59 kW; 79 hp), 100 S (1.8 litre, 90 PS or 66 kW; 89 hp) and 100 LS (1.8 litre, 100 PS or 74 kW; 99 hp) guise, while the Coupé was driven by a bored-out 1.9 litre developing 115 PS (85 kW; 113 hp). From April 1970 the 100 LS could be ordered with a three-speed automatic transmission sourced from Volkswagen.

The Audi 100 enjoyed a level of commercial success for which the company had not planned. As a distinguished German commentator pointed out, the rough engine note was unlikely to discourage buyers whose first car had been a Volkswagen and who aspired to drive a diesel powered (pre-turbo) Mercedes-Benz. Despite running the Ingolstadt production line at full capacity, supply fell short of demand to such an extent that during the summer of 1970 an additional production line for Audi 100s was set up in Volkswagen's own Wolfsburg plant, which made it the first water-cooled car to be produced in Germany's (and by some criteria the world's) largest car plant.

Starting with model year 1972 the 80 and 90 PS versions were replaced by a new regular-petrol-variant of the 1.8 litre engine developing 85 PS (84 hp/63 kW); at the same time, the 100 GL was introduced that featured the 1.9 liter engine formerly used in the Coupé S only.

In March 1971 the 500,000th Audi was produced. By now the Audi 100 had become the most commercially successful model in the company's history, so it is unsurprising that the car in question was an Audi 100 produced at the Ingolstadt plant.

In September 1973 the 100 received a minor facelift with a somewhat smaller grille and reshuffled taillight lens patterns. The rear torsion bar was replaced by coil springs. For model year 1975 the base 100 was re-christened the 100 L and received a 1.6 litre four-cylinder engine (coming out of the Audi 80). A four-wheel drive prototype of the Audi 100 C1 was built in 1976, long before the appearance of the quattro.

In the United States the Audi 100 appeared in 1970 in LS guise, with a 115 hp (86 kW) SAE 1.8 liter engine and with either two or four doors. For 1972 the engine was enlarged to 1.9 litres, but since the power figures were now in SAE net claimed power was down to a less impressive sounding 91 hp (68 kW). A base and a GL model were added, as was an automatic transmission. For 1974 the lineup was again restricted to the 100 LS, while the larger safety bumpers were now fitted. Power increased to 95 hp (71 kW) for 1975, courtesy of fuel injection. Standard equipment was also improved, but at the cost of a sizable price hike. In August 1977 the new Audi 5000 replaced the 100, although another 537 leftover cars were sold in 1978. The Coupé was never sold in the United States.

Audi 100 C2:

The restyled C2 Audi 100 was launched in 1976, with an in-line five-cylinder engine. It was initially a 100 PS (74 kW) engine offering "six-cylinder power and four-cylinder economy", and later upgraded to 136 PS (100 kW).

The Coupé was discontinued, but a five-door hatchback model, the 100 Avant, was launched in August 1977 as part of this generation. The mainstay of the range remained the four-door sedan model. A two-door sedan version was offered, primarily on the domestic market, from February 1977, but by now there was little demand, even in Germany, for large two-door sedans: few of these two-door Audi 100 C2s were sold.

At the end of September 1977, the Audi 100 became the manufacturer's first model to reach a production level of 1,000,000 units. The millionth Audi 100 was a hatchback Audi 100 Avant assembled not at the company's main Ingolstadt plant but to the west, at the Neckarsulm factory which, since the demise of the mainstream volume models from the NSU range, had been concentrating on providing additional production capacity for the fast selling Audi range.

Audi 100 C2 had differrent nad new engines.

Audi 100 C3:

Edging out the Ford Sierra as the 1983 European Car of the Year, the 1983 Audi 100 had a remarkably aerodynamic look, achieving a drag coefficient of 0.30 for its smoothest base model. The increased aerodynamic efficiency resulted in better fuel economy and consumers all over the world were waking up to this fact. This became a great marketing tool for Audi in the 1980s, and marked a huge leap forward from the boxy shape of the C2, as well as the technology it introduced, including the procon-ten safety system.

Audi was able to follow up on the modern smooth look first seen in this segment on the 1967 NSU Ro 80 and popularised by the 1974 Citroën CX. This rounded look became the norm by the 1990s. It also set a styling trend of flush wheel covers, a thick black side door moulding and blacked out window frames eventually adopted by a range of cars such as the 1984 Honda Accord and the Chrysler K cars. Audi innovated flush windows on the C3, a key area for aerodynamic drag that has been adopted by virtually all manufacturers today. In addition to giving it better fuel economy its aerodynamic body gave the 100 higher top speed than other cars of similar engine size.

The two-door models were no longer available, and the Audi 100 Avant was reintroduced as Audi's first attempt at a station wagon based on the 100. The 200, launched in 1983 continued as the upmarket variant with several versions of the 2.2 L turbo 5-cylinder available in different markets over its life ranging in power outputs from 165 PS (121 kW) MC engine, through the 200 PS (147 kW) versions to the final 220 PS (162 kW) 20-valve 3B engine available from 1991. Due to its low drag coefficient, the 1983 Audi 200 Turbo had a top speed of 139 mph (224 km/h). The MC turbo engine was available in the 100 as well for some markets.

The 1991 200 20V was distinguished by its flared front and rounded rear wheel arches instead of the flat type used for the rest of the 100-200 range, this allowed wider wheel and tire combinations to be fitted to 20V models. For many markets, the 20V Audi 200 gave customers a taste of performance levels that would later be seen in the C4-Chassis Audi S4, and S6. US Magazine articles of the period reported 0-60 times of the 20v Audi 200 under 7 seconds, with 1/4 mile times in the mid to upper 15 second mark.

The 100 also featured a 2.5 L straight-five direct injection turbo-diesel (TDI) model with 120 PS (88 kW) introduced in January 1990 (engine code 1T). A such-engined Audi 100 was the very first model to wear the now ubiquitous and hugely successful TDI label that changed the perception of diesel engines all over the world. It had a brief career in the C3, being replaced in December of that year when the C4 arrived.

Audi 100 C4:

Audi released the C4 (a heavily revised C3) in 1991. The C3-platform Audi V8 continued to be sold as a separate line. The major change for the C4 was the introduction of a 2.8 L, 90-degree, SOHC 12v, V6 engine. It was later joined by a 2.6 L variant, of the same configuration as the 2.8 L unit. They are essentially the same engines offered in the 1992, B4 Audi 80. The option of quattro permanent four-wheel drive was an option across the range, and the Audi 100 quattro was available with a ZF four-speed automatic gearbox.

For the 1995 model year, in conjunction with some styling revisions, Audi dropped the Audi 100 tag, renaming it the A6 instead. In addition, the existing 100-derived Audi S4 became the S6. The S4 name was later re-used for the high-performance derivative of the Audi A4. The Audi V8 had been replaced by the A8 in 1994.

The C4-based A6 continued until early 1997, when it was replaced by an all-new A6.

In 1994 Audi 100 C4 was replaced by Audi A6 C4, but it was allmost the same.

Audi 80

Hello, i'm talking about audi 80.

The Audi 80 is a compact executive car produced by the German car manufacturer Auto Union/Audi NSU Auto Union/Audi, from 1966 to 1996. It shared its platform with the Volkswagen Passat from 1973 to 1986 and was available as a saloon car/sedan, and an Avant (Audi's name for an estate car/station wagon). The coupé and convertible models were not badged as members of the range but shared the same platform and many parts.

In North America and Australia, the 80 was sold as the Audi Fox for model years 1973–79, and as the Audi 4000 for model years 1980–87 in the USA. The Audi 90 was an upmarket version of the Audi 80. The original Audi Cabriolet was badged thus, without a number, but was closely related to the 80/90.

There were several different internal combustion engine types, of which the petrol engines included the fuel-injected "E" (Einspritzung), and carburetor "S", and the diesel engines included "D" (Diesel), "TD" (TurboDiesel), or "TDI" (Turbocharged Direct Injection).

Audi 80 B1:

This model debuted in Europe in 1972 (with factory production starting in May 1972) as the Audi 80, and in 1973 in Australia and the United States as the Audi Fox, and was available as either a two-door or a four-door saloon (sedan). It effectively took the place of several models that Audi had discontinued (the F103 series, which included the first model designated as an "Audi 80"), and provided the company with a viable rival to the Opel Ascona and the Ford Taunus.

The Audi 80 was first equipped with 1.3- and 1.5-litre SOHC straight-4 petrol engines. The internal combustion engines were available in various rated power outputs. For the 1.3 L engines, (identification code: ZA) was rated at 55 PS (40 kW; 54 bhp), code: ZF was rated at 60 PS (44 kW; 59 bhp). The 1.5 L (codes: ZB, ZC) at 75 PS (55 kW; 74 bhp) for the ZB and 85 PS (63 kW; 84 bhp) for the ZC.

On the home market, two- and four- door saloons were available in base trim (55 or 60 PS, called simply Audi 80 and 80 S, respectively), as L models (LS with 75 PS engine) or as a more luxurious GL (85 PS only). In September 1973, Audi added the sporty 80 GT (two-door only) featuring a carburetted 1.6-litre engine (code: XX) rated at 100 PS (74 kW; 99 bhp).

The Audi 80 had a MacPherson strut front suspension, and a C-section beam rear axle located by trailing arms and a Panhard rod, and using coil springs and telescopic dampers.^[3]

Audi's design and development efforts paid off during the 1973 European Car of the Year competition where the 80 won ahead of the Renault 5 and the Alfa Romeo Alfetta.

A facelift in autumn 1976 brought about a revised front end in the style of the newly introduced Audi 100 C2 with square instead of round headlights, 1.6- instead of 1.5-litre engines (still of 75/85 PS) and a new 80 GTE model with a fuel-injected version of the 1.6-litre (110 PS (81 kW; 110 bhp)) replacing the former 80 GT.

The Fox had a 1.5 L engine rated at 55 hp (41 kW; 56 PS) attached to a four-speed manual transmission. Subsequent versions came with 1.6 L engines rated at 83 hp (62 kW; 84 PS).^[4]

In certain markets a five-door "Avant" (Audi's name for an estate/wagon) variant was offered — effectively a rebadged Volkswagen Passat with Audi front panels. The B1 platform was dropped from the European market in 1978, although it was sold into the 1979 model year in North America.

Audi 80 B2:

Audi presented a redesigned 80 based the B2 platform (Typ 81) in September 1978 and deliveries of the four door saloon/sedan began a few weeks later in Europe. Deliveries of the fuel injected GLE and two door bodied cars began early in 1979. The redesigned car was first seen in North America in 1979 (as a 1980 model). Audi continued to use the 80 nameplate in Europe, but badged their Typ 81 as the Audi 4000 in North America. The body of the B2 Audi 80 was designed by Giorgetto Giugiaro. No Avant variant was available, as the Volkswagen Passat filled that role.

In Europe, the 80 was the standard model, while after a 1984 facelift the Audi 90 was launched as a larger-engined version of the 80; with more options, and, aside from the 70 PS (51 kW; 69 bhp), four-cylinder 1.6l turbodiesel (TD) engine which was also available for the 80, two five-cylinder in-line petrol engines — a 2.0 with 115 PS (85 kW; 113 bhp) and a 2.2 with 136 PS (100 kW; 134 bhp) which was later modified into a 2.3. The 2.2 was available with a catalytic converter and power ratings of 115 PS (85 kW; 113 bhp) for front-drive and 120 PS (88 kW; 118 bhp) for quattro models. European models had two headlamp casings, while North American models generally had quad headlamps.

The Audi 5+5 was launched on to the Australian market in October 1981 and was described as a "uniquely Australian Special". After the Australian motoring press had driven the new B2 Audi 80, they beckoned Audi to fit the five-cylinder engine from the larger Audi 100. The 5+5 was essentially an 80 B2 four-door saloon with the 2,144 cc five-cylinder engine, the precursor to what would become the Audi 90.

In 1983, the 80 Sport was introduced in the UK, based on the GTE. It came with quattro-style Ronal alloys, rubber rear spoiler, deep chin spoiler, striped charcoal Recaro interior, and optional body graphics including full-length "Audi Sport" stripes. A special commemorative-edition version, the Audi 4000CS quattro, was made for the 1985, 1986, and 1987 model years.

Mid-1984, for the 1985 model year, Audi gave the B2 a subtle facelift with tail lights resembling the ones of the Typ 44 Audi 100, and different front and rear bumpers and headlights and an updated interior. In Europe, engines with catalytic converter emissions controls were made available for the first time.

The B2 platform proved to be both quite versatile and quite profitable; many components were shared to or borrowed from the Audi Coupé, Audi Quattro and Audi Sport Quattro, which in the process helped to cement the company into the public eye after their quattro permanent four-wheel drive system proved useful in various forms of racing.

The saloons were offered until late 1986 in Europe and 1987 abroad, and the B2-based Audi Coupé lasted through to 1988 (as an early 1989 model) before being changed. The Coupé shared many components, and its basic body shape, with the original Audi Quattro.

Audi 80 B3:

In September 1986, Audi released a new Typ 89 Audi 80 for the 1987 model year on the European market and introduced it elsewhere within a year. It was based on a new platform which broke the relationship with the Volkswagen B-series platforms, not being the same as the Passat's B3 platform. Although often called the typ 89 even among knowledgeable Audi enthusiasts, the official and correct nomenclature was its production code Typ 89 from 1987 to 1989, and Typ 8A from 1990 onwards. It introduced a new aerodynamic look and a fully galvanised bodyshell. This was the first mid-sized car to feature a fully zinc-coated body, giving it longevity and durability against corrosion perforation. This protective shield proved to be so effective that Audi extended its corrosion perforation warranty from the originally offered ten years to twelve years (during early pre-production, the body was expected to be good for only eight years). Audi still uses zinc galvanisation for all current steel-bodied models.

Unlike its predecessor, the type 89 was marketed worldwide only as the Audi 80 or Audi 90. For the most part, Audi transferred existing powertrain concepts to the new model, although fuel injection was now available for some engines. A range of new petrol and diesel inline four-cylinder engines became available to European customers along with the procon-ten safety system which became standard fitment from 1991.

In 1987, the inline five-cylinder Audi 90 was reintroduced as an upmarket, more luxurious variant of the 80. The 90 differs visually by the full width tail-light panel; headlights which featured additional high-beam lights and a slightly different front grille. The most obvious visual difference between the 80 and 90 are the indicators, which are moved from beside the headlights to the bumpers next to the fog lights, which were standard fitment on the 90. From 1989 to 1991 the 90 also offered the first 20-valve engine from Audi since the turbocharged engine used in the Audi Sport Quattro. This engine produced 170 PS (130 kW; 170 bhp) and featured in the front wheel drive 20V, 20V Sport and four-wheel drive 20V quattro derivatives. The non-quattro 20V models were 120 kg lighter.

The United Kingdom and Europe had similar versions: the Volkswagen Group wanted to ensure consistency across all markets, so the trim levels were similar. However, in North America, the range was more limited: a choice of 2.3 E and 2.3 quattro were available from 1988 to 1992.

Audi 80 B4:

The B3 obtained a major facelift for the 1992 model year in 1991. It was from then on known internally as the B4 (or Typ 8C). Changes from the B3 included a longer wheelbase, a fully redesigned fuel tank and rear axle to enable the use of folding seats, 15" roadwheels with more prominent wheel arches, redesigned and painted rear and front bumpers, as well as higher-quality materials for the interior. The front grille was merged with the bonnet and given a bolder look.

The B4 also marked the beginning of Audi's move into the German luxury mid-sized vehicle segment, which until then was clearly dominated by Mercedes-Benz and BMW. On the European market, and in Germany in particular, the B4 and its variants were highly successful and popular.

In Europe, the 90 name was discontinued, and all saloons were badged as 80, regardless of which engine they had. Audi of America went the opposite direction, and began selling the saloon as the 90. B4s for the American market typically offered more luxury even in the standard version, such as automatic transmission, cruise control, air conditioning and leather seats, all of which were usually optional at additional cost (or standard) on European models.

Because the United States does not recognise the international ECE Regulations on auto safety components and constructions, but rather maintains its own Federal Motor Vehicle Safety Standards, the front of the B4 had to be specially redesigned for vehicles sold in North America. The front and bumper had to be designed to accommodate impact energy absorbers not required outside North America. Instead of the dual-reflector headlamps, a single-reflector design was used inboard of an amber combination turn signal, parking, and side marker lamp and reflector wrapping around the corner, and fog lamps smaller than the rest-of-world items were placed the corners of the bumper air duct.

European market cars were now available with a selection of inline four-cylinder engines, as well as the familiar in-line five, and two different new V6 engines (2.6 and 2.8); the later 2.8 V6 was the only engine available for vehicles sold in North America. As another first, Audi introduced a new high-torque, direct-injection, turbocharged diesel engine, the 66 kilowatts (90 PS; 89 bhp) 1.9 TDI (Turbocharged Direct Injection). The standard 1.8-litre petrol engine of the B3 was discontinued; a two-litre, 66 kW (90 PS; 89 bhp), 4-cylinder petrol engine, a variation of the previously known 85 kW (116 PS; 114 bhp) 2.0 E engine, was now available for the base model.

With audi 80 B4 came and reliable engine 1.9 tdi.
