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.
