Audi is currently working on the hottest version of the Audi TT Roadster: the TT RS, a model that is expect to go on sale in 2009 as a Porsche Boxster competitor.
The TT RS Roadster will be powered by a twin-turbocharged 2.5-litre five-cylinder petrol engine. Output will be around 350 hp!
The Roadster will also feature Audi’s quattro all-wheel drive system mated with a six-speed manual gearbox; while DSG will be available as an option.
