660-Horsepower Audi TT RS Devours The Autobahn At 190 MPH

Audi Sport’s wonderful inline-five represents a profitable business opportunity for tuners all over the world, especially in Europe. Many aftermarket specialists have dissected the 2.5 TFSI over the years in an attempt to squeeze out every last drop of performance. From the Gyor factory in Hungary, the turbocharged mill makes an already healthy 400 horsepower and 354 pound-feet (480 Newton-meters) of torque.

That’s nothing compared to what the tuners can do depending on how big your pockets are and how far you’re willing to take output in your performance compact car from the Four Rings. Take for example BR-Performance, which offers a stage 4 kit for the latest TT RS equipped with the gasoline particulate filter.

One such car is featured in the adjacent video by hartvoorautosNL, showing the speedy coupe going flat out at the Autobahn while making all sorts of wonderful engine noises. If you’re wondering how much power the five-pot now delivers, you’d better sit down for this one – 660 hp. The power delivery to the Quattro all-wheel drive seems impressively natural even though the engine is now packing a lot more punch than before.

It’s worth mentioning that BR-Performance’s stage 4 kit makes “only” 610 hp but an optional IE intake extracts an additional 50 ponies. Torque number with the IE intake is not mentioned, but the standard stage 4 kit takes it to 780 Nm (575 lb-ft) or a whopping 300 Nm (221 lb-ft) more than the stock 2.5 TFSI engine. The tuner’s site also shows a modification available for the DSG by modifying the launch control from the original 3,500 rpm to 4,800 rpm. The rev limiter can also be loosened up from 7,000 rpm to 7,300 rpm, while the shift time decreases from 100 milliseconds to just 80 ms.

Calling it a “baby R8” is simply wrong because this TT RS has legitimate supercar levels of performance. As the British say, the driver gave it the proverbial beans in a top speed run, hitting 190 mph (305 km/h) on an unrestricted section of Germany’s glorious highway. It could’ve probably gone even faster, but traffic got in the way and the driver had to slow down.

These high-powered, high-speed TT RS builds are a testament to the engine’s tuning potential and make us wonder whether future versions of the inline-five will push out more power from the factory. Of course, reliability is a concern, but we’ve heard rumors of a Performance version for the next-generation RS3 due with close to 450 hp.
