The Audi TT RS, Coupe and Roadster, features a turbocharged 2.5-liter engine with FSI direct gasoline injection. It develops 250 kW (340 hp) and peak torque of 450 Nm (331.90 lb-ft), yet consumes an average of just 9.2 liters per 100 kilometers (25.57 US mpg).
The Audi TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Roadster in 4.7 seconds. Upon request, quattro GmbH will raise the governed top speed from 250 km/h (155.34 mph) to 280 km/h (173.98 mph). When the driver pushes the Sport button, a flap installed in the left exhaust tailpipe renders the unmistakable roar of the five-cylinder even more intense and the engine’s responsiveness is boosted further.
The power-to-weight ratio of the Audi TT RS Coupé – which weighs in at a mere 1,450 kilograms (3,196.70 lb) – is just 4.3 kilograms per hp; the TT RS Roadster’s power-to-weight ratio is 4.4 kg/hp. These low figures are due primarily to the extremely lightweight bodies – constructed as per the Audi Space Frame (ASF) principle – made of aluminum in the front and of sheet steel in the rear.
The Audi TT RS Coupe and TT RS Roadster, can now also be ordered with a seven-speed dual-clutch transmission. The TT RS Coupé consumes an average of 8.5 liters (27.67 US mpg) of fuel per 100 km and emits just 197 g/km (317.04 g/mile) of CO2.
Alongside the version with six-speed manual transmission, Audi is now making the TT RS available with an S tronic seven-speed dual-clutch transmission which perfectly unites dynamism, comfort and efficiency. Shifts are completed within just a few hundredths of a second by changing between the two clutches, and are smooth and very comfortable, with no perceptible interruption in the power flow.
