Audi are about to release RS7 model, which will be range-topping the A7. For now, A7 Sportback offers supercharged V6 with 300HP, but the sports version is something very different.

Audi RS7 is set to debut in the US in 2011. It will feature AWD and an 8-speed Tiptronic transmission, a sports suspension, larger air intakes in the front fascia and a set of 19" or 20" alloys.

The engine is expected to be a twin-turbocharged 4.0-liter V8 with 600HP to match the M version of BMW F10 and AMG version of E-class.

RS7 will also have an adaptive suspension and torque vectoring differential as well as the Quattro AWD hardware.  We are also eager to see, how tuners will boost the mighty engine.
