The 2.5-liter unit fitted to the Audi RS 3 Sportback and TT RS Coupé and Roadster features both turbocharging and FSI direct gasoline injection technology, two of Audi’s core technologies. 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 said of the 2.5-liter engine: "This is certainly the best turbocharged engine in recent years. Torque, power, and great sound – this engine has it all! It is a powerful, visceral reminder of the original quattro rally racing engine that put Audi on the map.”
Developed by quattro GmbH, the Audi TT RS Coupé can sprint from zero to 100 km/h (62 mph) in 4.3 seconds (Roadster: 4.4 seconds) and both the Coupè and Roadster have an optional top speed of 280 km/h (174 mph).
Audi now offers the same engine that powers the two TT RS models in the RS 3 Sportback. It takes 4.6 seconds to accelerate from zero to 100 km/h (62 mph) – a best-in-class performance figure. Its governed top speed is 250 km/h (155 mph).
This is the seventh category win in a row at the International Engine of the Year Awards for Audi TFSI technology. Between 2005 and 2009, the Audi 2.0-liter TFSI engine has won the award in the 1.8 to 2.0-liter category.
