Now in its sixth generation, the successor to the [[Audi 100]] is manufactured in [[Neckarsulm]], Germany, and is available in saloon and [[Station wagon|estate]] configurations, the latter marketed by Audi as the Avant. Audi's internal numbering treats the A6 as a continuation of the Audi 100 lineage, with the initial A6 designated as a member of the C4-series, followed by the C5, C6, C7, C8 and the C9. The related [[Audi A7]] is essentially a Sportback ([[liftback]]) version of the C7-series and C8-series A6 but is marketed under its own separate identity and model designation.

All generations of the A6 have offered either [[front-wheel-drive]] or [[Torsen]]-based [[four-wheel-drive]], marketed by Audi as their ''[[quattro (four-wheel-drive system)|quattro]]'' system. The A6 has also been used as the basis for the company's [[Audi allroad quattro|Allroad]] models since 1999.

[[Audi]]'s [[executive car]] was previously named the [[Audi 100]] (or Audi 5000 in the United States), and was released in three successive generations ([[Audi 100#C1|Audi C1]], [[Audi 100#C2|Audi C2]] and [[Audi 100#C3|Audi C3]]).<ref name="carautoportal">{{cite web|url=http://www.carautoportal.com/audi/audi-a6.php|archive-url=https://web.archive.org/web/20091025174124/http://www.carautoportal.com/audi/audi-a6.php|url-status = dead|archive-date=2009-10-25|title=Audi A6 Reference|access-date=2009-06-22|work=CarAutoPortal.com}}</ref> In 1994, the latest generation (C4) of the [[Audi 100#C4|Audi 100]] received a facelift and was renamed as the '''Audi A6''', to fit in with Audi's new alphanumeric nomenclature (as the full-size [[Audi A8|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 [[Straight-four engine|inline four-cylinder]], 2.0-litre 8v inline-four, 2.6-litre 12V [[V6 engine|V6]] and 2.8-litre 30v V6 petrol engines, with the 2.3-litre [[Straight-five engine|inline-five engine]] being dropped on most markets. For the [[diesel engine]]s, an inline-four 1.9 [[Turbocharged Direct Injection]] (TDI), and the inline-five (R5) 2.5 TDI with {{cvt|103|kW|PS bhp|0}} were available.

Most of the engine options were also available with Audi's [[Torsen]]-based [[quattro (four-wheel-drive system)|quattro]] permanent [[four-wheel-drive]] system. Amongst enthusiasts, the torsen-based Quattro<ref>{{Citation |title=Quattro (four-wheel-drive system) |date=2025-12-14 |work=Wikipedia |url=https://en.wikipedia.org/w/index.php?title=Quattro_(four-wheel-drive_system)&oldid=1327446552 |access-date=2026-02-26 |language=en}}</ref> system was the superior choice, offering better handling and consistent full-time all wheel drive. The A6 was available with saloon and Avant bodies.

=== S6 === {{Main|Audi S6#C4 (Typ 4A, 1994–1997)|l1 = Audi S6}}{{More citations needed|section|date=October 2025}}[[File:Audi S6 C4.jpg|left|thumb|Audi S6]] [[File:Audi S6 (14477159915) (cropped).jpg|thumb|Audi S6]] Upon introducing the C4 series A6, Audi made small revisions to what was previously known as the [[Audi S4]], renaming it the '''Audi S6'''; the S4 name would eventually be re-used for a completely different model derived from Audi's smaller [[Volkswagen B platform|Volkswagen Group B platform]]-based [[Audi A4]]. As this was the first S6 model from Audi, it is commonly referred to as the ''Ur-S6'', derived from the German augmentative, "'''Ur'''sprünglich" (meaning: original). It was available as both a [[sedan (automobile)|saloon/sedan]] (''type'' 4A5), and an "Avant" (''type'' 4A9) ([[station wagon|estate/wagon]]) to European and United States customers, but only as a saloon in Canada, Asia and Australia.

From its launch in late 1994, the Audi S6 was powered by a {{convert|2226|cc|1}} [[turbocharger|turbocharged]] [[straight-five engine|inline five-cylinder]] petrol engine (parts code prefix: 034, identification code: AAN) with a [[Robert Bosch GmbH|Bosch]] [[Motronic]] electronic [[engine control unit]] (ECU), producing a motive power output of {{convert|169|kW|PS bhp|0|abbr=on}} at 5,900 rpm and {{convert|258|lbft|Nm|0|abbr=on|order=flip}} at around 1,950 rpm,<ref>{{Cite web |last=Oldham|first=Scott|date=2021-08-17|title=All-Wheel Affordability: The first Audi S6 is a rare, turbocharged super-sedan|url=https://www.hagerty.com/media/car-profiles/all-wheel-affordability-the-first-audi-s6-is-a-rare-turbocharged-super-sedan/|access-date=2026-02-28|website=Hagerty Media|language=en-US}}</ref> on high [[octane rating|octane]] "Super Plus" 98RON unleaded petrol. This engine gave the S6 a top speed of {{convert|241|km/h|1|abbr=on}}, and allowed it to accelerate from 0 to {{convert|100|km/h|1|abbr=on}} in 6.7 seconds; with {{convert|160|km/h|1|abbr=on}} being reached in 17.5 seconds. The vehicle was available with a standard six-speed [[manual transmission]] (five-speed only in North America), and Audi's dynamic [[Torsen]] T-1 [[Quattro (four-wheel-drive system)|Quattro]] permanent [[four-wheel-drive]] system.

Audi made a 4.2-litre [[V8 engine]] (parts code prefix: 077, identification code: AEC) with a Bosch KE-Motronic ECU available as an option in the original European S4s, and made the decision to continue to do so with the S6, making a {{convert|213|kW|PS bhp|0|abbr=on}} version of the 4.2 available as an optional upgrade over the 2.2-litre inline five-cylinder turbo.<ref>{{Cite web |title=1994 Audi S6 Saloon and Avant Brochure|url=https://autocatalogarchive.com/wp-content/uploads/2022/03/Audi-A6-S6-1994-INT.pdf|website=Auto Catalog Archive|publisher=Audi}}</ref> Unlike the five-cylinder turbocharged version, the V8-powered S6 was supplied with a four-speed [[automatic transmission]] as standard but kept the Quattro four-wheel-drive. A six-speed manual gearbox was also available as an option.

===Audi S6 PLUS{{anchor|S6+}}=== [[File:Audi S6 Plus Limousine.jpg|thumb|right|Audi S6 Plus]] As a swan song to the C4 platform, an even more powerful, and very limited-production '''Audi S6 Plus''' was briefly available to European customers. The S6 Plus, developed by Audi's wholly owned high-performance subsidiary, '''[[quattro GmbH]]''', was available for sale during the 1997 [[model year]] only (production from June 1996 to October 1997). A total of 952 cars were produced; 855 Avants and 97 saloons.

It was powered by another version of the 32-valve (four valves per cylinder) 4.2-litre [[V8 engine]] (parts code prefix: 077, identification code: AHK, later to be seen in the [[Audi S8]] as AKH). Audi's performance division reworked key parts of the engine, increasing the maximum power to {{convert|240|kW|PS bhp|0|abbr=on}}. It was only available with a revised six-speed [[manual transmission]] (parts code prefix: 01E, identification code: DGU) ([[gear ratio]]s – 1st: 3.500, 2nd: 1.889, 3rd: 1.320, 4th: 1.034, 5th: 0.857, 6th: 0.730), with a final drive ratio of 4.111.

Further revisions were made to the suspension, brakes, and wheels. The front [[disc brake|brake discs]] were enlarged to {{convert|323|mm|1|abbr=on}} in diameter by {{convert|30|mm|2|abbr=on}} thick. Standard wheels were 8Jx17 "Avus" cast aluminium alloy wheels, with an optional 7Jx16 alloy wheel for use with winter tyres was also available.

The S6 Plus saloon could reach {{convert|100|km/h|1|abbr=on}} from a standstill in 5.6 seconds, with the Avant a tenth of a second slower at 5.7 seconds.

In February 1997, the introduction of a new A6 ('''''Typ'' 4B'''), based on a new design [[automobile platform]] – the [[Volkswagen Group C platform#C5|Volkswagen Group C5 platform]], with a new range of engines was announced and appeared in March at the [[Geneva Motor Show#1997|1997 Geneva Motor Show]]. This A6 was marketed in the same categories as the [[BMW 5 Series (E39)|BMW 5 Series]] and the [[Mercedes-Benz E-Class (W210)|Mercedes-Benz E-Class]]. The redesigned body had a [[coefficient of drag]] of 0.28.<ref>{{cite web|url=http://www.theautochannel.com/vehicles/new/geneva_97/g97vw.html#audi|title=The 67th Annual Geneva Car Show – 1997|access-date=14 July 2015}}</ref>

In 2000 and 2001, the "C5" A6 was on ''[[Car and Driver]]'' magazine's ''Ten Best'' list. This A6 was available with 30-valve 2.4- and 2.8-litre [[V6 engine]]s, with numerous other engine configurations available globally. 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.<ref>{{cite web|url=http://www.cars.com/audi/a6/1999/expert-reviews/?review=2&reviewId=35454|title=1999 Audi A6|author=Anita And Paul Lienert|access-date=14 July 2015|archive-url=https://web.archive.org/web/20150715022929/http://www.cars.com/audi/a6/1999/expert-reviews/?review=2&reviewId=35454|archive-date=15 July 2015|url-status=dead}}</ref> In Canada, there was no Avant (Audi's name for an [[station wagon|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. In compliance with [[FMVSS|federal standards]], 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 lamp|daytime running lights]] as standard equipment. North American C5 A6 models received the 2.8-litre, 30-valve V6 engine, the 2.7-litre [[twin-turbo|"Biturbo"]] V6 also found in the [[Audi S4#B5|B5 platform S4]], developing {{cvt|250|PS|kW hp|0}}, and the 4.2-litre 40-valve [[V8 engine|V8]] [[petrol engine]] with {{cvt|300|PS|kW PS hp|0|order=out}}; the two more powerful engines were only offered with [[quattro (four-wheel-drive system)|quattro]] permanent [[four-wheel drive]]. 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 wheels (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 tail light 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 {{cvt|130|PS|kW PS hp|0|order=out}}. The 1.9-litre [[Turbocharged Direct Injection]] (TDI) was tweaked to produce a maximum power output of {{cvt|130|PS|kW PS hp|0|order=out}}, and {{cvt|310|Nm|lbft|0}} of torque, and was mated to a six-speed [[manual transmission|manual gearbox]]. The 2.4-litre V6 was named the BDV 30 valves and gained an extra 5 hp and better balancing, and the 2.8-litre V6 engine was replaced by a 3.0-litre engine with {{cvt|162|kW|PS bhp|0}}. The turbocharged 2.7-litre was revised, resulting in {{convert|184|kW|PS bhp|0|abbr=on}} and {{cvt|330|Nm|lbft|0}}, controlled by standard quattro system. The V6 diesel was also slightly modified resulting in {{cvt|120|kW|PS bhp|0}} (after the second modification) and {{cvt|350|Nm|lbft|0}}. A new more powerful V6 diesel was also introduced with {{cvt|180|PS|kW PS hp|0|order=out}} and {{cvt|370|Nm|lbft|0}}. The 4.2-litre V8 engine which arrived in 2001 remained unchanged.

Also new was the [[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]].

The second-generation A6 was on ''Car and Driver'' magazine's [[Car and Driver Ten Best|''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, Mercedes-Benz E-Class, Jaguar XF, and Infiniti M.

A long wheelbase version of the A6 C5 was available in China for the first time, making this model the first stretched German sedan developed especially for that country.

=== S6 and RS 6 === {{Main|Audi S6#C5 (Typ 4B, 1999–2003)|l1 = Audi S6}}

The [[Audi S6#C5|Audi S6]] is a high-powered variant of the A6, featuring a modified version of the 4.2-litre [[V8 engine]] producing {{convert|250|kW|PS bhp|0|abbr=on}} and {{convert|420|Nm|lbft|0|abbr=on}}. It was available as a saloon and Avant although the Avant version was the only one sold in North America.

[[File:Audi RS6 Avant - Flickr - The Car Spy (24).jpg|thumb|Audi RS 6 Avant]] In the late years of the A6 C5 design, a higher-performance limited-run [[Audi RS6#C5|Audi RS 6]] model was presented. Weighing in excess of {{convert|1840|kg|0|abbr=on}} and producing {{convert|331|kW|PS bhp|0|abbr=on}} and {{convert|560|Nm|0|abbr=on}}, the RS 6 was capable of 0-{{convert|100|km/h|1|abbr=on}} in 4.5 seconds, and on to {{convert|200|km/h|1|abbr=on}} in under 17 seconds. Initially available as only an Avant, a saloon variant was later added; the saloon version being the only version available to the North American market. The RS 6 saloon finished first in a May 2003 ''[[Car and Driver]]'' comparison test against the [[BMW M5#E39|BMW M5 (E39)]], [[Mercedes-Benz E-Class (W211)#E 55 AMG (2003–2006)|Mercedes-Benz E 55 AMG (W211)]], and Jaguar S-Type R.<ref>{{cite web|url=http://www.caranddriver.com/comparisons/2003-audi-rs-6-vs-bmw-m5-jaguar-s-type-r-m-b-e55-amg-comparison-test|title=2003 Audi RS 6 vs. BMW M5, Jaguar S-type R, M-B E55 AMG|access-date=14 July 2015}}</ref>

=== allroad quattro (1999–2005) === [[File:Audi allroad quattro 2.5 TDI (C5, Facelift) – Frontansicht, 3. Juli 2011, Essen.jpg|thumb|left|Audi allroad quattro 2.5 TDI (Germany)]] [[File:2005 Audi allroad (4B MY04) 2.5 TDI quattro Avant station wagon (2015-07-09) 02.jpg|thumb|left|Audi allroad quattro 2.5 TDI (Australia)]]

Audi's C5 series A6 Avant formed the basis for a semi-offroad model in 1999, labeled "Audi allroad quattro". Compared to the regular A6, the allroad featured an advanced [[air suspension]] system, allowing for increased ground clearance; larger diameter all-terrain tyres, and flared fenders and bumpers with matte finish, giving it a distinct appearance and more overall flexibility over varying terrain. The allroad's ride height was also increased with 25 mm subframe spacers; and overall frame stiffness increased with reinforced welds on the subframe mounts and A, B, and C pillars, the floor pan being produced with 20% thicker steel. As the name "allroad Quattro" suggests, Audi's [[Torsen]]-based [[quattro (four-wheel-drive system)|quattro]] permanent [[four-wheel-drive]] system was standard equipment for all versions.

The standard adjustable air suspension system can lift the car high enough to provide {{cvt|208|mm|in|1}} of ground clearance; a low-range mode (an option with manual transmission), absent from other Quattro-equipped vehicles, can be selected with the touch of a button. When used together, the two systems made it possible for the allroad to complete an official [[Land Rover]] test-course, thus far it is the only car-based SUV that has been proven capable of doing so in testing.{{Citation needed|date=September 2018}} Conversely, the air suspension can lower the vehicle down to only {{cvt|142|mm|in|1}} above road level, and simultaneously stiffen the spring and damper rates to provide a sporty driving experience, much like that of the conventional A6 with the sports suspension.

Audi's 2.7-litre, [[turbocharger|biturbo]] [[V6 engine|V6]] [[petrol engine]] with {{convert|250|PS|kW hp|0|abbr=on}} and {{cvt|350|Nm|lbft|0}} of peak torque was available initially, alongside the 2.5-litre TDI diesel unit with {{cvt|180|PS|kW hp|0}} and {{cvt|370|Nm|lbft|0}} of torque. A variant of the corporate 4.2-litre V8 petrol engine was made available in 2003, and a less powerful TDI (163 bhp) followed in 2004.

Audi stopped production of the allroad in July 2005. Although the model continued to be available for sale throughout 2006 in Europe, there was no 2006 model year for North America.

With the return of the "allroad" nameplate to North America, in the form of the 2013 A4 allroad Quattro, the C5-Platform allroad Quattro has begun to take the name "Ur-allroad." The '[[wikt:ur-|Ur-]]' is used in the German language, as a prefix to signify 'ancient' or 'early ancestor' (e.g., great-grandmother is Urgroßmutter), and is used informally by car enthusiasts worldwide to refer to the ''original''<ref name="carautoportal-ur">{{Cite web|url=http://www.carautoportal.com/audi/audi-urs4-s6.php|title=Ur-S4 / Ur-S6|access-date=2009-07-09|work=carautoportal.com|url-status = dead|archive-url=https://web.archive.org/web/20091025174236/http://www.carautoportal.com/audi/audi-urs4-s6.php|archive-date=2009-10-25}}</ref> [[Audi Quattro]] that was produced from 1980 to 1991 (the "Ur-Quattro"). The use of the term was then extended to the original S4 and S6 models to differentiate them from later models with the same name, and more recently to the C5 allroad models ("Ur-allroad").

===Initial release=== The '''''Typ'' 4F''' A6 was released in 2004. Designed by Satoshi Wada in 2001, this model is visually an evolution of the C5, but was lengthened to {{convert|4927|mm|1|abbr=on}}, and has the new Audi "single-frame grille". Like other contemporary Audis, the A6 has a "tornado line" that runs from the front lights to the rear lights just below the body shoulders.<ref>{{cite web|url= http://www.autoblog.com/buy/2009-Audi-A6/expert-review/ |title=2009 Audi A6 |date=22 August 2024 |publisher=Autoblog.com}}</ref>

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 [[height adjustable suspension|suspension configuration]] and optional electronic accessories through a central screen interface. This has the advantage of minimising the number of buttons normally found on a dashboard by replacing them with controls that operate multiple devices using the integrated display.

On the engines, the new [[gasoline direct injection|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]] model 09E available in the [[four-wheel-drive]] models. Audi's "trademark" [[Torsen]]-based [[quattro (four-wheel-drive system)|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 was previewed by the [[Audi Avantissimo]] concept in 2001 and arrived during the course of 2005. The A6 All-road 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 engine]]s, or a 3.2-litre V6 or 4.2-litre V8 [[petrol engine]].

===A6L (2005–2009)=== The A6L is a long [[wheelbase]] version of the A6 sedan for the Chinese market. The vehicle was unveiled in 2005 at the [[Shanghai motor show|Shanghai Motor Show]].

The vehicles went on sale in the middle of 2005. Early models include A6L 2.4, with A6L 2.0 [[Turbo fuel stratified injection|TFSI]] (170 PS) followed shortly after. A6L 3.0 Quattro (218 PS) and A6L 4.2 Quattro (335 PS) were introduced in 2005. Other models include A6 3.0.<ref>{{cite web|url=http://www.audiworld.com/news/05/chinaa6/content.shtml|title=New Audi A6 presented as a Long-Wheelbase version exclusively for China|date=2005-03-08|work=AudiWorld.com|access-date=2009-02-03}}</ref>

===S6=== {{Main|Audi S6#C6 (Typ 4F, 2006–2011)|l1 = Audi S6}}

The [[Audi S6#C6|Audi S6]] performance variant was introduced in the [[Frankfurt Motor Show]], and produced from early 2006 until 2011. It is powered by a 5.2-litre [[gasoline direct injection|Fuel Stratified Injection]] (FSI) [[V10 engine]] producing {{convert|320|kW|PS bhp|0|abbr=on}} and {{convert|540|Nm|0|abbr=on}} of torque, a de-tuned engine taken from the Lamborghini Gallardo. The S6 reaches {{convert|100|km/h|1|abbr=on}} from a standstill in 5.2 seconds and a quarter mile in 13.5 seconds.<ref>{{cite web|url=http://www.jbcarpages.com/audi/a6/|title=Audi A6 & S6 Reviews & Specs|work=JB car pages}}</ref>

Audi announced the C6 series allroad in 2005 and released it the following year. This model was called the '''Audi A6 allroad quattro''' (unlike the previous version, the ''Audi allroad quattro'', with no reference to the A6 nomenclature).

The Audi A6 allroad quattro again featured adaptive air suspension and [[quattro (four wheel drive system)|quattro]] permanent [[four-wheel drive]] system. The A6 allroad was powered by a choice of two [[gasoline direct injection|Fuel Stratified Injection]] (FSI) [[petrol engine]]s, a 3.2-litre V6 and a 4.2-litre V8, and two [[Turbocharged Direct Injection|TDI]] [[diesel engine]]s, a {{convert|180|PS|kW|0|abbr=on}} 2.7 L and a {{convert|225|PS|kW|0|abbr=on}} (233 only in the US) 3.0 L. The [[tiptronic]] gearbox is standard on the 4.2 V8 and the 2.7 TDI, but optional on the 3.2 FSI and 3.0 TDI.

The five-mode air suspension can be raised by up to {{convert|60|mm|in|2|abbr=on}} to provide [[ground clearance]] of {{convert|185|mm|in|2|abbr=on}} which is better than the older four-mode.

The car featured a number of off-road styling cues including larger bumpers and sills.

In some European markets, this A6 allroad quattro was more expensive than the larger [[Audi Q7]], but an air suspension is an expensive option in the Q7. In its native country, Germany, it cost a few hundred Euros less than the Q7.

===Awards=== In 2005, the A6 won the ''[[World Car of the Year]]'' award, and has also won the ''Practical Caravan'' "Towcar of the Year" awards, due to its array of towing features such as adjustable suspension height and damping, and the presence of a 123 [[towing#Trailer Stability Program or TSP|Trailer Stability Programme]].

Audi unveiled a [[facelift (automobile)|facelifted]] "C6" Audi A6 on 12 August 2008, at the [[Moscow International Automobile Salon|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 [[Light-emitting diode|LEDs]], the taillights extend towards the centre 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, 2008 Audi A4, and 2009 Audi Q5 (the latter three being all-new generations).

The intakes below the headlamps are inspired by the Audi RS5.<ref name="auto">{{cite web|url=http://www.autoblog.com/buy/2009-Audi-A6/expert-review/ |title=2009 Audi A6 |date=22 August 2024 |publisher=Autoblog.com}}</ref> 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 new front and rear fascias from RS6 would be used on the facelifted A6 and S6 lineup.

There are now six petrol and four diesel engines available for the upgraded A6. All petrol engines now feature cylinder-direct [[gasoline direct injection|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 {{cvt|300|PS|kW bhp|0}}, 3.0-litre supercharged V6 - badged either 3.0 TFSI or 3.0T. This new engine is shared with the B8-generation [[Audi S4]] and [[Audi S5|S5]], although slightly detuned vs. the S-cars, and makes the A6 3.0T only 0.1 seconds slower {{0to60mph}} than the more powerful but heavier 4.2 V8 variant and 5.2 V10-bearing [[Audi S6|S6]].<ref>{{cite web|author=Prestige quattro |url=https://www.edmunds.com/audi/s6/2010/review/ |title=2010 Audi S6 Review and Ratings |publisher=Edmunds.com |access-date=2020-01-08}}</ref>

Also updated for 2009 is the Quattro all-wheel-drive setup, which is already found on the 2008 Audi A5 and 2008 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.<ref name="auto"/>

US models went on sale as 2009 model year vehicles, and arrived in dealerships by the beginning of January. Early models include A6 3.2 FSI (sedan), A6 3.0 TFSI quattro (sedan/Avant), A6 4.2 FSI quattro (sedan), S6 5.2 FSI (sedan).<ref>{{cite web|url=http://www.autoblog.com/2008/12/19/audi-prices-a6-s6-starting-at-45-100-75-900/|title=Audi Prices A6/S6 starting at $45,100/$75,900| first=Chris | last = Shunk|work=Autoblog|date=19 December 2008 |access-date=14 July 2015}}</ref>

The latest version of ultra-high-performance [[Audi RS6#C6|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 {{convert|4991|cc||abbr=on}} [[V10 engine|V10]] [[twin-turbo]]charged, [[gasoline direct injection|Fuel Stratified Injection]] engine with a [[dry sump]] lubrication system. It produces a power output of {{convert|426|kW|PS bhp|0|abbr=on}}, and {{convert|650|Nm|0|abbr=on}} of torque, making it the most powerful vehicle ever produced by Audi at the time. This has now been surpassed by the Audi R8.

Initially available only as an Avant, the saloon version went on sale in mid-October 2008.

===Initial release=== The fourth generation C7 series Audi A6 (internally designated '''''Typ 4G''''') was leaked online in December 2010 and 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.<ref>{{cite web|url=http://www.autoblog.com/buy/2012-Audi-A6/expert-review/ |title=2012 Audi A6 |date=22 August 2024 |publisher=Autoblog.com}}</ref><ref>{{cite web|url=http://www.automoblog.net/2010/11/30/breaking-leaked-photos-give-audi-a6-an-early-reveal/|title=Leaked Photos Give Audi A6 an Early Reveal|publisher=Automoblog.net |date=2010-11-30 |access-date=2010-12-04}}</ref> The A6 shares its interior, platform, and powertrain ([[Volkswagen Group MLB platform|Modular Longitudinal Platform]]) with the [[Audi A7]] four door sedan, which had been released shortly before also in 2011. Design work began in 2006, with Jurgen Loffler's exterior design being chosen in 2008.<ref>{{cite web|first=Michael |last=Harley |url=http://www.autoblog.com/2011/06/08/2012-audi-a7-review-road-test/ |title=2012 Audi A7 |publisher=Autoblog.com |access-date=2012-03-24}}</ref>

The new A6 increased its wheelbase by nearly {{convert|3|in|mm|0|abbr=on}} and its width by {{convert|2.7|in|mm|abbr=on}}. The redesign also decreased the car's [[automobile drag coefficient|drag coefficient]] to 0.25.

European engine choices for the C7 include two petrol engines – a 2.8-litre FSI V6 with {{convert|204|hp|kW|0|abbr=on}} and a {{convert|300|hp|kW|0|abbr=on}}, 3.0-litre supercharged FSI engine – and two diesel engines – a 2.0-litre inline four-cylinder and a 3.0-litre turbocharged diesel engine in three states of tune.<ref name=A6future>{{cite web|url=http://www.audisite.com/1705/new-look-new-future-new-audi-a6/|title=New Look, New Future, New Audi A6|publisher=AudiSite.com |date=2010-12-04 |access-date=2010-12-04| archive-url= https://web.archive.org/web/20101222121535/http://www.audisite.com/1705/new-look-new-future-new-audi-a6/| archive-date= 22 December 2010 |url-status = live}}</ref> The European A6 3.0 TFSI will have an optional seven-speed dual-clutch transmission and an air suspension option, two features that will not be available on the United States model.<ref>{{cite web|first=Rex |last=Roy |url=http://www.autoblog.com/2011/02/17/2012-audi-a6-first-drive-review-road-test/ |title=First Drive: 2012 Audi A6 |date=17 February 2011 |publisher=Autoblog.com |access-date=2012-03-24}}</ref>

===A6 allroad quattro (2012–2018)=== {{Multiple image | align = left | direction = vertical | width = | image1 = 2014 Audi A6 Allroad TDi Quattro Automatic 3.0 Front.jpg | image2 = 2014 Audi A6 Allroad TDi Quattro Automatic 3.0 Rear.jpg | caption2 = A6 allroad quattro }}

The 2013 '''A6 allroad Quattro''' was unveiled at the [[Geneva Motor Show#2012|2012 Geneva Motor Show]], alongside the 2012 [[Audi RS 4|RS4 Avant]]. Sales began in 2012. The first UK deliveries arrived in July 2012.

The allroad variant contains several unique features. Audi designed more than 1,100 new, unique parts for the allroad, setting it apart from the standard A6 and making it a true all-terrain vehicle.{{Citation needed|date=September 2018}} Most obvious, the allroad received special bumpers and fender flares, giving it an aggressive offroad appearance. The bumpers and fender flares feature a tough-wearing, matte finish, contrasting the rest of the body. The roof received this same coating, as well as four longitudinal ribs for increased strength. The unique bumpers also have integrated aluminium skid plates. The allroad featured larger diameter tires than the standard A6 for improved offroad capabilities. Redesigned headlights, larger side mirrors, and a lack of door "rub strips" are unique to the allroad. The allroad comes standard with an [[Height adjustable suspension|adjustable]] [[air suspension]] system can lift the car high enough to provide {{convert|208|mm|in|0|abbr=on}} of ground clearance; a low-range mode (an option with manual transmission), absent from other quattro-equipped vehicles, can be selected with the touch of a button. When used together, the two systems made it possible for the allroad to complete an official [[Land Rover]] test-course, thus far it is the only car-based SUV that has been proven capable of doing so in testing.{{Citation needed|date=September 2018}}

Conversely, the air suspension can lower the vehicle down to only {{convert|142|mm|in|0|abbr=on}} above road level, and simultaneously stiffen the spring and damper rates to provide a sporty driving experience, much like that of the conventional A6 with the sports suspension.

It went on sale in early 2012. Early variants included 3.0 TFSI quattro (310 PS), 3.0 TDI quattro (204 PS), 3.0 TDI quattro (245 PS), 3.0 TDI quattro (313 PS).<ref>{{Cite web|url=http://www.audi.com/com/brand/en/company/news/models_and_services.detail.2012~01~the_new_audi_a6_allroad.html|title=The new Audi A6 allroad – the Avant for any kind of road|access-date=November 27, 2019|archive-url=https://web.archive.org/web/20120401163053/http://www.audi.com/com/brand/en/company/news/models_and_services.detail.2012~01~the_new_audi_a6_allroad.html|archive-date=April 1, 2012|url-status=dead}}</ref><ref>{{cite web|url=http://www.autoblog.com/2012/01/11/audi-releases-new-a6-allroad-with-no-word-on-u-s-availabilit/|title=Audi releases new A6 Allroad... with no word on U.S. availability|author=Noah Joseph|work=Autoblog|date=11 January 2012 |access-date=14 July 2015}}</ref>

=== Engines === All engines are equipped with the MHEV Plus [[mild hybrid]] system includes a 48-volt battery, [[BAS hybrid|belt-alternator starter]], and an electric motor/generator. At full acceleration, the electric motor can provide an additional {{convert|24|PS|kW hp|0|abbr=on}} and {{convert|230|Nm|lbft|0|abbr=on}} of torque, while also using the braking energy to recharge the small battery. According to Audi, this setup allows the A6 to drive solely on electric power during low-speed maneuvers.<ref name=":0" />

In May 2025, the [[plug-in hybrid electric vehicle]] (PHEV) powertrain marketed as the e-hybrid quattro was introduced and it is available two power outputs. The plug-in hybrid powertrain uses the 2.0 TFSI engine from the EA888 series producing {{convert|252|PS|kW hp|0|abbr=on}}, combined with an electric motor that produces an output of {{convert|143|PS|kW hp|0|abbr=on}}. The 25.9 kWh [[lithium-ion battery]] is positioned above the rear axle, the battery capacity increase by 45% compared to its predecessor, which means the A6 models can drive more than {{convert|100|km|mile|0|abbr=on}} in electric-only range. The maximum AC charging power of 11 kW and the charging time duration from 0 to 100 percent in just 2.5 hours. The degree of thrust recuperation performance in electric driving mode (EV mode) can be adjusted to three different levels using paddles on the steering wheel and the vehicle automatically recovers energy when this function is activated. Two operating modes are available to the hybrid management system: “EV” and “hybrid.” In EV mode, the plug-in hybrid models run solely on electric power. In hybrid mode, the hybrid management system maintains a specific charge level as needed in order to save enough electrical energy for later use. Combined with the quattro ultra drive and standard all-wheel steering, the electrified dual-clutch transmission increases manoeuvrability at low speeds and provides additional stability at higher speeds.<ref>{{Cite press release |title=Sporty meets efficiency: the new A6 plug-in hybrid models |date=2025-05-06 |publisher=Audi MediaCenter |url=https://www.audi-mediacenter.com/en/press-releases/sporty-meets-efficiency-the-new-a6-plug-in-hybrid-models-16615#battery-capacity-and-energy-density-significantly-increased}}</ref> {| class="wikitable collapsible" ! colspan="7" style="text-align:center" |Petrol engines |- ! rowspan="2" |Model ! rowspan="2" |Codename ! rowspan="2" |Engine ! rowspan="2" |Power ! rowspan="2" |Torque !Top speed !{{convert|0–100|km/h|mph|0|abbr=on}} |- !Avant !Avant |- |2.0 TFSI<ref>{{Cite web |title=2025 Audi A6 (C9) Avant 2.0 TFSI S tronic Specs, Performance, Comparisons |url=https://www.ultimatespecs.com/car-specs/Audi/145978/Audi-A6-(C9)-Avant-20-TFSI-S-tronic.html |access-date=2025-03-30 |website=ultimateSPECS |language=en}}</ref> |VW EA888 |{{convert|1984|cc|L|1|abbr=on|order=flip}} |{{convert|204|PS|kW hp|0|abbr=on}} |{{convert|340|Nm|lbft|0|abbr=on}} |{{convert|240|km/h|mph|0|abbr=on}} |8.3 s |- |3.0 V6 TFSI<ref>{{Cite web |title=2025 Audi A6 (C9) Avant 3.0 V6 TFSI MHEV quattro S tronic Specs, Performance, Comparisons |url=https://www.ultimatespecs.com/car-specs/Audi/145976/Audi-A6-(C9)-Avant-30-V6-TFSI-MHEV-quattro-S-tronic.html |access-date=2025-03-30 |website=ultimateSPECS |language=en}}</ref> |VW EA839 evo |{{convert|2995|cc|L|1|abbr=on|order=flip}} |{{convert|367|PS|kW hp|0|abbr=on}} |{{convert|550|Nm|lbft|0|abbr=on}} |{{convert|250|km/h|mph|0|abbr=on}} |4.7 s |- ! colspan="7" style="text-align:center" |Petrol plug-in hybrid engines |- |2.0 TFSI e quattro |VW EA888 |{{convert|1984|cc|L|1|abbr=on|order=flip}} |{{convert|367|PS|kW hp|0|abbr=on}} |{{convert|500|Nm|lbft|0|abbr=on}} |{{convert|250|km/h|mph|0|abbr=on}} |4.5–5.1 s |- ! colspan="7" |Diesel engines |- |2.0 TDI<ref>{{Cite web |title=2025 Audi A6 (C9) Avant 2.0 TDI MHEV S tronic Specs, Performance, Comparisons |url=https://www.ultimatespecs.com/car-specs/Audi/145972/Audi-A6-(C9)-Avant-20-TDI-MHEV-S-tronic.html |access-date=2025-03-30 |website=ultimateSPECS |language=en}}</ref> | rowspan="2" |VW EA288 evo | rowspan="2" |{{convert|1968|cc|L|1|abbr=on|order=flip}} | rowspan="2" |{{convert|204|PS|kW hp|0|abbr=on}} | rowspan="2" |{{convert|400|Nm|lbft|0|abbr=on}} |{{convert|241|km/h|mph|0|abbr=on}} |7.9 s |- |2.0 TDI quattro<ref>{{Cite web |title=2025 Audi A6 (C9) Avant 2.0 TDI MHEV quattro S tronic Specs, Performance, Comparisons |url=https://www.ultimatespecs.com/car-specs/Audi/145971/Audi-A6-(C9)-Avant-20-TDI-MHEV-quattro-S-tronic.html |access-date=2025-03-30 |website=ultimateSPECS |language=en}}</ref> |{{convert|238|km/h|mph|0|abbr=on}} |7.0 s |}

==Use in China== According to Dunne & Company, a research company, as of 2011, purchases in China and Hong Kong make up about half of the 229,200 Audi A6s sold in the world. By 2012 many government officials in China began driving with Audi A6s. After a 1994 campaign from the Chinese government to have officials stop driving Mercedes stretch limousines, the officials began using black Audi A6 cars. Michael Wines of ''[[The New York Times]]'' wrote that "More than a perk, the black Audi is a rolling advertisement for its occupant’s importance and impunity in a nation obsessed with status."<ref>Wines, Michael.
