Audi A7 TDI
New for 2014 is a diesel powered A7. The Audi A7 is a big, beautiful, spacious sports sedan with an ACE in the hole; that being the wonderful fuel economy. The TDI power plant can manage 24 MPG in the city and 38 MPG on the highway. That might not sound like a lot, but consider this is a full-sized luxury car getting the same fuel economy as a tiny compact. The price for the A7 TDI is $66,900.
The Audi A7 is drop dead gorgeous thanks to the sleek hatchback design. But the car is not just good to look at; the A7 excels in virtually every other aspect. Under the hood is a 3.0 liter turbocharged V-6 diesel engine that makes 240 horsepower and 428 lb-ft. of torque. Believe it or not the TDI model only weighs 66 lbs. more than the regular gas model.
