Despite the performance of the A6 3.2 it delivers great mpg for such a large car. It excels on the open road. With cruise it is possible to achieve a range of 650+ miles on a tankful. see full Audi A6 / S6 / RS6 review

With the FSI and V6, I regularly see 27 mpg in city. And arround 30-32 mpg highway (no A/C on, and cruising at 80 mph). see full Audi A6 / S6 / RS6 review

It's hard to imagine such a powerful luxury car can get such great gas mileage. On a recent trip to Montreal I calculated my fuel economy to be somewhere in the 27mpg range....incredible! see full Audi A6 / S6 / RS6 review

Typically 22-24 in-town and 29-31 on the road. Excellent economy for car size and level of comfort. see full Audi A6 / S6 / RS6 review
