Audi planes to reveal a concept of the A7 at the North American International Auto Show in Detroit in January. As you can only imagine, the number 7 will be placed on top of the A4, A5 and A6 but placed right below the A8. In theory that would be a pretty big vehicle with that lineup placement as you can see in the sketches below.
The new Audi A7 may sport a new 204hp 2.8L, supercharged 300hp 3.0L and a 394hp 4.2L V8 to top things off on the high-end model. We expect to eventually see a RS7 model with a twin-turbo 600hp 5.0L V10 similar to those offered currently in the newer R8 and Lamborghini sisters.
