Five-cylinder engines are in Audi’s DNA. The company is once again building such an engine – this time a high-performance engine. The Audi TT RS, developed by quattro GmbH, sports a turbocharged 2.5-liter engine with FSI direct gasoline injection under the hood that produces 250 kW (340 hp) and 450 Nm (332 lb-ft) of torque, yet consumes only 9.2 liters/100 km (25.57 US mpg). In conjunction with quattro permanent all-wheel drive, the powerful five-cylinder model offers explosive performance, making the compact Audi TT RS Roadster – a purist driving machine.
Potent five-cylinder gasoline engines enjoy a long tradition at Audi, powering cars like the “Ur-quattro” (original quattro) to the head of the pack. Audi has resumed using this recipe. The newly developed engine combines a turbocharger with FSI direct gasoline injection to make the TT RS an uncompromising sports car.
The TFSI delivers 250 kW (340 hp) from a displacement of 2,480 cc: an output of 137.1 hp per liter. Weighing only the Roadster (1,510 kilograms (3,329 lb)) this figure is 4.4 kilograms (9.7 lb) – the low values are made possible by the extremely lightweight bodies utilizing the Audi Space Frame (ASF). They are made of aluminum up front and steel sheet at the rear.
The TT RS Roadster in 4.7 seconds. The governed top speed of 250 km/h (155 mph) is merely the official figure for both versions; as an option, it can be increased to 280 km/h (174 mph). Peak torque of 450 Nm (332 lb-ft) is available between 1,600 and 5,300 rpm, providing tremendous pulling power. The TT RS Roadster consumes just 9.5 l/100 km (24.76 US mpg) – another example of how Audi combines dynamics and efficiency.
