This year, Audi's mid-sized Q7 SUV is offered with a 221 horsepower 3,0-litre V6 TDI (turbo-diesel) engine producing an impressive 406 lbs/ft of torque. The 3,6-litre V6 and 4,2-litre V8 engines are still available. The Q7 comes equipped with a six-speed automatic transmission and the Quattro all-wheel drive system only, a more than adequate configuration to rival competitors like the Acura MDX, BMW X5, Mercedes-Benz Classe M, and Porsche Cayenne.
