About the existence of the TTRS and RS5 coupes we already knew, and now here's another details about the two new future sports-cars from Audi. The TTRS will be unveiled at the Paris Motor Show this autumn, while the RS5 will come sometime in 2009.

According to Fourtitude, the TTRS will be powered by a turbocharged 2.5-liters 5-cylinder engine that delivers 350 hp.

About the RS5's powerplant they only make speculations like everyone else. First choice is a V10 Twin Turbo engine used in the RS6, but they say is an unlikely choice. Second choice is V10 Normally Aspirated, same choice as the Road & Track magazine. Third choice is a 4.2-liter FSI engine that delivers 450 hp and 500 ft-lbs. And finally a V8 Normally Aspirated engine that delivers 420 hp. But which one will actually power the RS5 no one knows at the moment. Only time will tell!
