The wraps have been taken off the new Audi TT Clubsport Turbo concept and it really is something revolutionary, and not because it features a gigantic spoiler in the rear. The fact is; The Audi TT isn’t that special, and with the TT Clubsport Turbo we get a larger bored out 2.5 liter 5 cylinder engine coupled to a nice healthy turbocharger that releases some massive horsepower numbers comparable to respectable supercars. We are talking 600 hp and 479 lb-ft of torque, figures that are incredibly good for such a light car.
Austria hosts this annual tuning festival called the Wörthersee Tour tuning fest which features some great German machines regardless of the make, and Audi seized the opportunity to introduce their sick track tuned Audi TT Clubsport Turbo concept, interesting bit is: Audi R&D chief Ulrich Hackenberg confirms that most of technology introduced in the concept is “close to production readiness.”
The 2.5 Liter 5 cylinder engine is quite small, so Audi engineers had to innovate to extract every bit of power without losing the functionality of being a normal car. So they used bigger turbochargers and Direct Fuel Injection, and added an electric motor that helps boost the turbos at lower revs to ensure responsiveness throughout the entire rev range without any turbo lag. Which they already introduced a while back with the electric turbocharged Audi A5 concept.
They called this system the E-Turbo which works in a not so complicated way – The electric motor spools the smaller turbo rapidly without any perceptible delay at low engine revs while allowing the bigger turbo to spin faster when there is little exhaust gasses in to create enough boost, basically all you need to know is that it takes care of turbo lag by spinning one turbo electrically before the other.
“The electric bi-turbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power,” Audi R&D chief Ulrich Hackenberg explains. “In our TDI [diesel] engines, we are close to production readiness with this technology; we are now presenting it in a [gasoline-powered] TFSI.”
The difference between Audi TT Clubsport Turbo concept and other cars that also have a similar system is that Audi engineers claim that there isn’t turbo lag what so ever in any driving situation, expect this technology to be in the new Audi TT RS. This concept does 0-60mph in 3.6 seconds and tops out at 192 mph thanks to the new E-Turbo technology and the smart Quattro all-wheel drive system packaged with a standard Audi six-speed manual transmission and a lot of weight saving.
