Audi (C4) A6 saloon

Audi (C4) A6 Avant (US)

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 right-hand-drive Audi 100s had run out before expected, and before the rest of mainland Europe.

The new engines for the A6 were 1.8-litre 20 vinline 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 C5 A6 saloon

Audi C5 A6 Avant

In late 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. 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 Italian-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 late 1997, and the Avant in 1998 in Europe. In the United States, the C4 continued for 1997, with the C5 saloon available in 1998, and the C5 Avant available in 1999. 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 1999 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 headlampsand grille design (before being introduced in 2002 to all other A6 models), largerroadwheels (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 kilowatts (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 ft·lbf) 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 ft·lbf), 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 ft·lbf). A new more powerful V6 diesel was also introduced with 132 kilowatts (179 PS; 177 bhp) and 370 newton metres (273 ft·lbf). 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.

C5 S6 and RS6

The Audi S6 was a high-powered variant of the A6, featuring a modified version of the 4.2-litre V8 engine producing 250 kilowatts (340 PS; 335 bhp) and 420 newton metres (310 ft·lbf). It was available as a saloon and Avant.

In the late years of the A6 C5 design, an ultra-high-performance limited-run Audi RS6 model was presented. Weighing in excess of 1,840kilograms (4,057 lb) and producing 331 kilowatts (450 PS; 444 bhp) and 560 newton metres (413 ft·lbf), it propels the RS6 from 0-100 kilometres per hour (62.1 mph) in 4.5 seconds, and on to 200 km/h (124.3 mph) in under 17 seconds. Initially available as only an Avant, a saloon variant was later added.

Audi A6 (C6) 3.2 FSI quattro saloon (Australia)

Audi A6 (C6) Avant (Germany)

The new C6-generation A6 was released in 2004. Designed by Walter de'Silva, the new model is visually an evolution of the C5, but is lengthened to 4,927 millimetres (194.0 in), and incorporates the new Audi trademark "single-frame grille". Like other contemporary Audis, the A6 has a "tornado line" that runs 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 assuspension 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.

In 2005, the new Audi A6 won the World Car of the Year award, and has recently won its class in the Practical Caravan "tow car of the year" awards, due to its array of towing features such as adjustable suspension height and damping, and the presence of a Trailer Stability Programme.

Like the previous model, the A6 is available with other body options. The Avant arrived during the course of 2005, while in China, a long wheelbase version was introduced in the same year, named A6L.The allroad variant (now called 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.

C6 facelift

Audi (C6) A6 Avant (facelifted)

Audi (C6) A6 sedan (facelifted)

Audi unveiled a facelifted "C6" Audi A6 on 12 August 2008, at the Moscow International Motor Show. The refresh incorporates some modern Audi design cues to keep the A6 current with the rest of the Audi lineup. There are minor cosmetic changes to the front and rear lights which now have daytime running LEDs, the taillights extend towards the center of the trunk lid and pinch off at the license plate mount, however their shape remains rectangular compared to the more sculpted light clusters found in the 2008 Audi A5, 2009 Audi A4, and 2009 Audi Q5 (the latter three being all-new generations). The intakes below the headlamps are inspired by the Audi RS5. The A6's six (per side) front light-emitting diode (LED) daytime running lights (DRLs) are located within the main headlamp housing, similar to RS6's placement of the LEDs (ten per side), whereas on the S6 these front LEDs (five per side) are found adjacent to the fog lamps in the lower front bumper. The RS6 which was unveiled in April 2008 already sported the new front and rear fascias that would feature on the facelifted A6 and S6 lineup.

Also updated for 2009 is the Quattro all-wheel drive setup, which is already found on the 2008 Audi A5 and 2009 Audi A4. This new system features a 40/60 front-to-rear torque split and offers a more balanced feel, reducing the understeer that comes from 50/50 AWD platforms.

There are now six petrol and four diesel engines available for the upgraded A6. All petrol engines now feature cylinder-direct Fuel Stratified Injection (FSI) technology, and all diesel engines now feature common rail (CR) and Turbocharged Direct Injection (TDI) technologies. There is a new petrol engine, a 300 PS (221 kW; 296 bhp) 3.0-litre supercharged V6, badged as 3.0 TFSI or 3.0T. This new engine is shared with the 2010 Audi S4 and S5 Cabriolet, although in the latter two applications in a higher state of tune and mated to a 7-speed S-tronic dual-clutch transmission.

The new engine and revised quattro system give the 2009 Audi A6 3.0 TFSI almost equivalent performance to the Audi S6 5.2 FSI (which is unchanged except for receiving the cosmetic tweaks like the rest of the Audi A6 lineup). Moreover, the S6's weight is 4,500 pounds and 59 percent of weight is distributed to the front which increases understeer.

C6 S6 and RS6

The sporting S6 was introduced in the Frankfurt Motor Show, with sales beginning in early 2006. It is powered by a 5.2-litre Fuel Stratified Injection (FSI) V10 engine producing a 320 kilowatts (435 PS; 429 bhp) and 540 newton metres (398 ft·lbf). The S6 reaches 100 kilometres per hour (62.1 mph) from a standstill in 5.2 seconds, and the quarter mile 13.5 seconds.

The latest version of ultra-high-performance Audi RS6 was launched in September 2008 and produced until the third quarter of 2010. Based upon the V10 engine powering the S6, the RS6 features an all-aluminium alloy 5.0-litre (4,991 cubic centimetres (304.6 cu in)) 90° V10 twin-turbocharged, Fuel Stratified Injection (FSI), with a dry sump lubrication system. It produces a power output of 426 kilowatts (579 PS; 571 bhp), and 650 newton metres (479 ft·lbf) of torque, making it the most powerful vehicle ever produced by Audi. Initially available only as an Avant, the saloon version was released in late 2008.

The next-generation Audi A6 (internally designated Typ 4G) was launched in early 2011 for the European market and in North America and India soon after. It is heavily influenced by the Audi A7, pulling elements from both its interior and exterior details.

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 2011 A6 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-litre inline four-cylinder and a 3.0-litre turbocharged diesel engine in three states of tune.

For North America, the Audi A6 3.0 TSFI quattro will be powered by a 3.0L supercharged V6 putting out 310 hp 325 ft.lb, the same engine carried over from the previous-generation 2009 Audi A6 3.0T, 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 TSFI FrontTrak (front-wheel drive) with a 2.0L turbocharged inline-4, the same engine in the Audi A4 and Q5, but mated to the Multitronic CVT (continuous variable transmission). Autoblog.com reports that "a 3.0-litre turbo-diesel V6 will be offered in the A6 in the not-too-distant future."

The car 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.
