Spy Shots: Audi TT RS... that won't be made, info pg.2

[vexor]

Caught testing in Germany, this white prototype looks similar to the test hacks originally spied in Finnish cold-weather testing late last year. But under the skin, this machine features a more performance-focused package. Details are still relatively scarce about the RS - but it is tipped to use a new twin-turbocharged version of the ubiquitous two-litre TSFI four-cylinder engine. No details on power output yet, but given that single-blower version of that unit already produce 250bhp, it's safe to expect a figure around, or in excess of, 300bhp. 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. The TT RS is expected to break cover officially before the end of this year. It will be eagerly awaited by performance enthusiasts - unlike the original car, the new model has good enough driving dynamics to cope with the extra grunt.
