Every year, the “International Engine of the Year” awards are held to honor, well, the best engines of the year. Obviously. There are different categories for engines of different sizes. Audi’s 2.5 liter TFSI turbocharged five-cylinder engine, used in the Audi TT RS and RS3 Sedan, has just won the award for the 2.0 – 2.5 liter category.
“The five-cylinder has been indelibly linked to the Audi brand for over 40 years, and we continue to refine and develop it,” said Peter Mertens, Member of the Board of Management for Technical Development at AUDI AG. “Last year we presented the Audi TT RS, the model in which the newly developed, aluminum five-cylinder is making its debut.”
In the Audi TT RS, as well as the new RS3 Sedan, the 2.5 liter turbo-five makes 400 hp and 369 lb-ft of torque. When paired with the seven-speed dual-clutch gearbox, the Audi TT RS is capable of 0-60 mph in around 3.7 seconds, which makes it by far and away the fastest car in its class. It crushes the BMW M2, Mercedes-AMG A45 and Porsche 718 Cayman S in pure performance.
But it isn’t just the power of the engine that makes it so great. It’s also decently fuel efficient for such a powerful engine, with a combined fuel consumption in l/100 km of 8.4 – 8.2 and combined CO2emissions in g/km: 192 – 187. Even still, though, that’s not what makes the 2.5 TFSI so special. The real kicker is its noise. With its bark and snarl at low revs and high-pitched scream at high revs, it sounds like an old-school Group B Rally car. Except it doesn’t have the immense turbo lag of rally cars from that era. Instead, its power delivery is smooth and its powerband is linear. It’s just a brilliant engine.
We’re glad Audi keeps making turbo five-pots, as they’re quite rare in the industry these days. What’s even better is both how good they are and how often Audi is willing to use them. We will likely see more uses of this engine in the future, as the brand expands its RS lineup.
