Another year and another victory for Audi with its 2.5-litre five-cylinder turbo heart. And this latest win takes Ingolstadt’s finest trophy tally in this category class alone to an amazing eight since the turn of the decade.
That the 405ps powerhouse has again cemented itself as the best design in this grouping is a true testament to Audi’s engineering prowess. Since the engine debuted in 2010 it has been known for its unmistakable crackling, popping soundtrack, reminiscent of Quattro’s rally heyday in the 1980s. Also since its launch, Audi has continued to evolve the 2.5 five-cylinder unit, keeping it refreshed, tuned and ahead of the competition.
For this year, the RS turbo heart fended off competition from some very talented rivals – including stablemate Porsche with its all-new 2.5 four-cylinder turbo. The engine, which drives the 718 Boxster S and the 718 Cayman S, pushed the Audi 2.5 victor all the way, but eventually fell short, 111 points in the red. Meanwhile other challengers successfully defeated in the class included offerings from Ford, Mercedes-Benz, Mazda and Toyota.
But it’s not hard to see why the Audi engine won. Packed full of technologies providing pure performance and sporting character, the refreshed RS unit now drives Audi’s most powerful TT – the TT RS – in its latest application, delivering 405ps output and 480Nm torque.
Judges were keen to wax lyrical about the five-pot that just seems to get better with age. Freelancer Yves Maroselli marvelled, “Audi has made power delivery from this special five-cylinder unit so refined and really exciting at the same time.”
Natan Tazelaar, a jury member from the Netherlands, further confirmed the reasons for the motor’s ongoing appeal: “The Audi 2.5-litre deserves points simply for being a five-cylinder, but next to that it sounds great, is extremely powerful and can be very docile and calm, or wild and outrageous.”
