Audi joins a handful of automakers that were honoured for its power units. The Audi 2.5-litre TFSI won the Engine of the Year title under the 2.0-litre to 2.5-litre category for the fourth year running.

The first iteration of this legendary five-cylinder engine impressed the motorsport world with its performance and unmistakable soundtrack - powering iconic cars like the original Audi quattro and Sport quattro S1. Now its legacy continues in the TT RS Coupe and Roadster, featuring two Audi core technologies - turbocharging and FSI petrol direct injection.

The 2.5-litre TFSI unit will also power the RS Q3 with 310bhp and delivering a fuel economy of up to 32.1mpg on a combined cycle, thanks in part to a Start-Stop system and a regulated oil pump that only supplies lubricant when needed. Efficiency does not hinder performance as the RS Q3 takes just 5.5 seconds to hit 100km/h before reaching its restricted top speed of 250km/h.

The Audi TT RS plus Coupe and Roadster models have a displacement of 2,480 cc and a power output of 360bhp with peak torque rated at 465Nm, enabling a century sprint timing of 4.1 seconds for the Coupe and 4.2 seconds for the Roadster with a top speed of 280km/h.
