The production-based racer features motorsport-friendly upgrades like a roll-over cage and safety-optimised fuel tank and Audi says modifications will be identical for all future customer sport versions.
The car gets a TFSI engine delivering about 340 hp, and the front apron, rear apron and the rear wing have been developed from the production Audi TT RS. The hood, doors and boot lid are made of CFRP and the windows of plastic, and customers will get S-tronic transmission with a differential lock, modified production suspension with adjustable dampers, plus 9.5 x 18 inch light alloy wheels.
The Audi TT GT4 is planned to sell for about 120,000 euros, they tell us, and the car was launched in Shanghai because the regular TT has just gone on sale there.
Five-time Le Mans winner Frank Biela did some demo laps in the new Audi TT on the street circuit in Shanghai during the DTM weekend just gone, hence the window stickers.
