As the latest entry in a growing class of 4-door sports cars, the all new Audi A7 combines the cool looks and deft handling of a sports coupe with the extra size and length of a luxury sedan. Fitted with quattro all-wheel drive and a 3.0-liter supercharged TFSI V6 engine that promises V8 power, the A7 may be big, but that sure isn't slowing it down.
