For the fourth year in a row, the Audi 2.5 litre TFSI – fitted in the Audi TT RS Coupé and Roadster – has been named International Engine of the Year. Selected by a jury of 87 international motoring journalists in the 2 to 2.5 litre category, this is the ninth category award in a row for Audi TFSI technology. Soon the engine will also power the Audi RS Q3, our first RS model SUV.
