When released at the end of the year, the TT RS will go head-to-head with the Porsche Cayman. There are reports the engine performance will be boosted to 350hp using twin sequential turbochargers, a figure that is low enough that it won't impede on the R8 but high enough to offers an attractive alternative to the 272hp TTS. All this power will be directed through Audi's permanent 4WD Quattro system and six-speed manual transmission.
We've got the TT, we've got the more powerful TTS, now all we have to wait for is the super powerful TT RS and judging by these latest shots that wait is nearly over. Our spies caught this completely undisguised Audi TT RS prototype whilst undergoing some hot weather testing in Arizona.
Pricing for the new model is expected to start at around €50,000.
