What is it?
The best-selling and most affordable model in the new A6 line-up, tested here with the six-speed manual transmision. Power comes from a mildly-updated version of Audi’s familiar two-litre diesel with common-rail injection, which now makes 175bhp and 280lb ft of torque and records an impressive 129g/km and 57.6mpg in official figures. The CO2 is 10g/km less than the outgoing TDIe A6 and the fuel economy 4mpg better.
These frugal new figures explain why the 2.0 TDi is the best-seller: three-quarters of A6 buyers will plump for the four-cylinder diesel with half of them opting for the manual.
With these improved figures, the new A6 matches its great rival, the 520d manual, for both CO2 and fuel consumption, which will be of great interest to company car tax drivers pondering their next drive.
Also worth noting is the expected improvement in the forthcoming A6 2.0TDi automatic, available in early May. Tipped to sneak ahead of the 520d automatic with a promised 133g/km, although the official homologation figure isn’t yet confirmed, it employs the Multitronic CVT, now updated with an extra programmable step to take it to eight-speeds.
There are plenty of other technical highlights in the new A6, most pleasingly a weight reduction to 1575kg, largely thanks to the more compact footprint and lightweight body construction.
Alloy is used extensively in the A6 including cast-alloy suspension towers - tech previously reserved for the A8 luxury saloon - alloy doors, front wings, bonnet, boot lid and parcel shelf.
This SE spec saloon also includes an SD card-based sat nav system as standard, a significant spec advantage over BMW, which charges over £1500 for its entry-level nav.
What’s it like?
Much better-looking in the flesh than the photos and less-clone-of-A4 than you might think from pictures. There’s real presence about the styling and a pleasingly long-and-low stance. The standard 17in alloys are a bit weedy though; the optional 18-inch versions add beef to the looks.
