The 2.5-liter unit in the Audi TT RS features both turbocharging and FSI direct gasoline injection technology, two of Audi’s core technologies, and marked a return to five cylinder engines for the brand with the four rings. With a displacement of 2,480 cubic centimeters, this engine produces 250 kW (340 hp) between 5,400 and 6,500 rpm and peak torque of 450 Nm (332 lb-ft) from 1,600 to 5,300 rpm.
International Engine of the Year jury members felt that the 2.5-liter engine in the TT RS is: “Torque, power, a beautiful sound – this engine has it all. This is five-cylinder architecture at its best”.
This powerful five-cylinder engine is also surprisingly frugal, requiring an average of just 9.2 liters/100 km (25.57 US mpg) in the Coupé, while the Roadster needs only 9.5 l/100 km (24.76 US mpg).
The engine’s low weight of only 183 kilograms (403.45 lb) is also a top figure. It helps keep the total weight of the TT RS low and also offers significant advantages for the distribution of axle loads and thus for the car’s handling.
Developed by quattro GmbH, the Audi TT RS was launched in the summer of 2009. The Coupé can sprint from zero to 100 km/h (62 mph) in 4.6 seconds and from zero to 200 km/h (124 mph) in 15.9 seconds. It has an optional top speed of 280 km/h (174 mph).
This is the sixth category win in a row at the International Engine of the Year Awards for Audi TFSI technology. For the last five years, the Audi 2.0-liter TFSI engine has won the award in the 1.8 to 2.0-liter category. FSI direct gasoline injection and turbocharging are two of Audi’s core technologies.
