GREEN | 7 out of 10
Audi A6: 25/33 mpg, 28 mpg combined (2.0T, FWD); 20/29 mpg, 23 mpg combined (2.0T, AWD); 18/27 mpg, 22 mpg combined (3.0T); 24/38 mpg, 29 mpg combined (TDI)
The V6, for example, is up 1 mpg city and 2 mpg highway compared to 2010 models.
Fuel economy, though, looks good for a car in this class. EPA ratings are 19 mpg city and 28 highway compared with 18 and 26 for the previous A6 3.0T Quattro. We averaged 23 over the course of our two-week test.
Car and Driver
With either Audi's turbocharged four-cylinder or its supercharged V-6, the A6 turns in competitive fuel-economy numbers. Can we just call the wide span between the new TDI turbodiesel and the super S6 a wash?
With the 2.0T, the A6 earns its best gas mileage ratings. The catch? To get those 25/33-mpg figures, you'll have to put up with a continuously variable transmission, a gearbox that seems out of tune with Audi's luxury niche. That's true just for front-drive models; with the all-wheel-drive turbo four, the transmission's an eight-speed automatic, and fuel economy registers at 20/29 mpg or 23 mpg combined.
Gas mileage isn't too bad with the 3.0T and quattro. The supercharged, direct-injected V-6 powerplant and its standard all-wheel drive deliver 18/27-mpg fuel economy, or 22 mpg combined.
For the best numbers of the lineup, look no further than the A6 TDI, new this year and on deck with 24/38 mpg EPA ratings, or 29 mpg combined. That should more than offset the S6's 17/27 mpg, or 20 mpg combined, given Audi's ambition for turbodiesel sales.
Audi's TDI diesel finally slots into the A6 here, and it's capable of great fuel-economy numbers.
