Audi will introduce the A5/S5 sportback next year and short after that the RS5 Sportback with 440 hp 3.0TFSI V6 Supercharged engine with a bigger type of TVS (Twin Vortices Series) Roots-Compressor.
The key word is "Downsizing" and the V6 SC engine is the way to go.
More power, more torque, less fuel, lower CO2 emissions.
Another + point is that the handling will be up to new RS standard, lighther, faster, more fun to drive.
