Here’s info on the regular A7: What it is: The Audi A7 is a large four-door hatchback conceived along the same lines as BMW’s 5 Series Gran Turismo. It combines a coupelike profile with the comfort of a sedan and the practicality of a station wagon, Audi says. The A7 slots between the A6 and A8 sedans in Audi’s lineup, and competitors include the 5 Series GT and Porsche Panamera.
The A7 now comes only with a supercharged gas V-6 engine. Audi has dropped the turbo-diesel V-6 while it works to resolve an emissions-cheating scandal. Performance variants of the A7 are available as the S7 and RS 7, both of which are powered by turbocharged V-8 engines. (Skip to details on the: RS 7)
