The Audi A6 range has been revised and it includes an ‘ultra’ version with economy of 64mpg and emissions of 114g/km CO2.
The new Audi A6 Saloon and Avant ranges have styling revisions, upgraded lighting options, a new infotainment system and new transmissions.
In the UK the engine line-up for the new A6 and A6 Avant will comprise four TDI engines with either four or six cylinders and either single or twin turbo charging. All engines comply with the Euro 6 emission standard, and their CO2 emissions have been reduced by as much as 22 percent. As before, the most efficient engine – the 2.0-litre TDI four-cylinder with 190PS – is reserved for ultra versions of the Saloon and Avant which can return up to 64mpg with CO2 output from as little as 114g/km. Despite its sports styling, 18-inch alloy wheels and extensive specification, even the A6 2.0 TDI ultra S line Saloon with S tronic transmission achieves these exceptional economy and emissions figures.
The trio of 3.0-litre six-cylinder TDI ‘clean diesel’ units kicks off with a single-turbo V6 with 218PS which replaces the existing 204PS version, and is followed by a 272PS variant, also with a single charger, which takes over from the outgoing 245PS unit. At the top of the range, the 3.0 TDI clean diesel biturbo produces 320PS, an increase of 7PS over its existing equivalent.
The high‑performance diesel is paired with an eight‑speed tiptronic automatic transmission. All other engine variants are linked to either a newly designed six‑speed manual gearbox that is particularly lightweight and low-friction, or a seven‑speed S tronic twin-clutch transmission. In the versions with front-wheel drive, a fully redeveloped dual-clutch transmission replaces the familiar eight-speed multitronic continuously variable transmission.
The reassurance of quattro all-wheel-drive is available in conjunction with all engines bar the 2.0-litre TDI, and in versions with 272PS and above, the quattro permanent all‑wheel drive system can be supplemented with the sport differential, which actively distributes power between the rear wheels.
The new Audi A6 allroad quattro, which is based on the A6 Avant, features a raised body accentuated by wheel arch extensions and stainless steel protectors that encapsulate the underside of the front and rear ends. It rides on adaptive air suspension with allroad-specific settings and is powered by three 3.0‑litre V6 TDI engines with outputs of 218PS, 272PS and 320PS.
The latest A6 is now open for UK ordering ahead of first deliveries in late 2014.
