The Audi A7 is a four-door, four-passenger car. In profile, the A7 has a long sweeping roofline that looks similar to other Audi sedans, but the A7 has a large hatchback in place of a traditional trunk. The A7 is similar in size to the latest A6, but its aggressive roofline and four passenger seating are more likely to intrigue buyers that might have considered the Mercedes-Benz CLS-Class. A supercharged V6 engine rated at 310-bhp is mated with an eight-speed automatic transmission to power all four wheels. Like other Audi models, the A7 is offered in Premium, Premium Plus, and Prestige trim levels. The base Premium model is well equipped, with the higher trim levels adding features like LED headlamps, four-zone climate control, and larger wheels/tires.
