Audi has recently announced the 2014 A7 model line which includes the A7 and the S7. Along with these two, Audi has also introduced two new models in the A7 line – the A7 TDI and the much anticipated RS7. In total there will be four A7 models to choose from which Audi describes as the perfect blend of progressive design, advanced technology and versatility. Since the RS7 is most awaited of the four models we will start with it first. The RS7 is most powerful RS model ever offered in the US and packs track oriented performance in a five door coupe.

The car is powered by a twin-turbo 4.0 TFSI V8 engine, generating a healthy 560 bhp that launches the RS7 from 0 – 60 mph in just 3.7 seconds. The engine also features an innovative cylinder on demand technology wherein the RS7 deactivates cylinders 2, 3, 5 and 8
