( http://www.TFLcar.com ) The 2014 Audi A7 TDI is a sport and fuel efficient luxury car. We put the A6, A7 and Q5 through their paces in the recent 2014 Audi TDI Efficiency Rally held in Washington, DC and the results of the drive lived up to the expectations set by Audi. The drive took us through Virginia and Maryland, along highways, scenic byways, and through lots of twists and turns. The only way you'd have known we were driving diesels was the TDI Clean Diesel graphic on the sides of all our pristine white Audis. They were quiet, smooth and comfortable to drive, and to ride in as a passenger.
When it came time to tally our results, even with one set of drivers aiming to drive as hard as possible and get the worst mileage (raises hand) the average for the group was 38.1 miles per gallon.
