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 review

For a car that requires 91+ octane, it would be nice if it got better gas mileage in city driving (around 16-18 mpg). The mileage on the highway is much better (up to 26 mpg). see full Audi A6 / S6 review
 

TrueDelta Reviews the Real Gas Mileage of the Mercedes-Benz E-Class

Mercedes-Benz E-Class Real Gas Mileage: Pros
YearComment
2014 The latest diesels tend to be much smoother, quieter, and more powerful than those of just a few years ago. But people still don't buy them for their smoothness, quietness, or quickness. Gas engines maintain a lead in these areas. People buy diesels for fuel economy, and here the Mercedes-Benz E250 BlueTEC excels. Its EPA numbers are best-in-class: 28 mpg city and 42 mpg highway with rear-wheel-drive (RWD) and 27/38 with all-wheel-drive (AWD). Even in E400 Hybrid form the gasoline V6 in the E-Class manages only 24/30. The Audi A6 TDI, offered only with AWD, scores significantly lower than the E250 in city driving: 24/38. The BMW 535d splits the difference in city driving, but runs with the Audi on the highway: 26/38 with RWD and 26/37 with AWD. So, based on the EPA numbers, the Mercedes has a significant fuel economy advantage, especially on the highway. Combine the EPA figures with a 21 gallon fuel tank, and the E250 BlueTEC can cover up to 900 miles between fill-ups. (This is especially attractive when you consider the sliminess of diesel fuel. Even much more than with gas, which largely evaporates when not contained, you do not want to spill any diesel on you or your clothing.) Switching to the real-world numbers reported by the cars' trip computers, the Mercedes (tested with AWD) retains a clear edge over the Audi on the highway, where the trip computers reported 45 and 38, respectively. In suburban driving with a light right foot the results were closer, about 40 to 37. I did test the Mercedes in the Bay Area of California, rather than back home in Michigan. On my usual suburban route it probably would have managed a few more miles per gallon. Also add two-to-three mpg for RWD rather than AWD. Most of my driving in the E250 was done along the scenic California coast, where a leisurely drive with infrequent stops but plentiful hilly curves netted 37 mpg on the way south and 41 on the return. Quite good for a fairly heavy all-wheel-drive luxury sedan--but the Audi (based on similar driving in an A7 TDI) would have been close. The real challenge comes from BMW. In my suburban driving the 535d's trip computer reported from 37 to 47, with low 40s typical. On one highway drive it reported an astounding 53.8 (but on another a mere 38). The tested 535d was RWD. Even so, if both trip computers were similarly accurate the BMW could be about as efficient as the Mercedes in real-world driving, while being considerably more powerful. Also, the 535d isn't the only BMW diesel sedan available in North America. If you can live with less interior space and less power, the Bavarians also offer the 328d (compared to the E250 here). The much lighter, four-cylinder car achieves EPA ratings of 32/45 with RWD and 31/43 with AWD, suggesting a clear advantage in city and suburban driving if not on the highway. see full Mercedes-Benz E-Class review
