Audi TT RS was caught testing on the roads in Germany. The new RS coupe powered by a twin-turbo Audi’s 2-liter TSFI stratified fuel injection engine. No details on power output yet, but given that single-blower version of that unit already produce 250bhp. That will put the car at least 50bhp above the current range-topper, the 3.2-litre V6 model. The twin-turbo engine is likely to be mated to six-speed manual and S-tronic transmissions.
