International Engine of the Year Award 2010 goes to Audi's straight five TFSI in the 2-2.5-liter category

The turbocharged 2.5-liter FSI engine (TFSI) has been awarded the International Engine of the Year Award 2010 in the 2-2.5-liter category, as a result of the voting by 71 leading motoring journalists from 35 countries. This is the sixth category win in a row at the International Engine of the Year Awards for Audi TFSI technology.

The straight five cylinder unit is a derivative of the 2-liter TFSI unit, and is being used inside the Audi TT RS, developed by the quattro GmbH and launched in the summer of 2009. As you already may know, the TFSI moniker stands for both turbocharging and FSI direct gasoline injection technology.

It also marks the return to five cylinder engines for Audi, the displacement of 2,5-litre. Two of the Audi's major technologies combined make 250 kW (340 hp) between 5,400 and 6,500 rpm and peak torque of 450 Nm from 1,600 to 5,300 rpm.

The fuel consumption of the Audi TT RS with this engine is being kept low when power is not needed, returning an average of just 9.2 liters/100 km in the Coupé, while the Roadster needs only 9.5 l/100 km.

Another significance is the the engine’s low weight (183 kg), which helps keep the total weight of the TT RS low and also offers advantages for the distribution of axle loads and thus for the car’s handling. The Coupé can sprint from zero to 100 km/h in 4.6 seconds and from zero to 200 km/h in 15.9 seconds. It has an optional top speed of 280 km/h.

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.
