These images are not the greatest, but they prove that Audi is indeed working on a model to counter Mercedes-Benz's CLS "four-door coupe". It will probably be called the A7.
Based on the new A8 platform, the car is expected to make its global debut in 2010.
Ingolstadt's new four-door sedan with a coupe-like roofline will follow Audi's current design philosophy and will, according to reports, be as luxuriously equipped as the A8 flagship sedan.
The manufacturer's new 6.0-litre V12 TDI engine is expected to form part of the engine line-up.
Audi's latest quattro system, which promises improved traction and stability, will likely be a key feature, too.
