Remember when Mercedes-Benz brought out the A45 AMG with the world’s most powerful production 2-litre, 4-cylinder engine? Well, they can keep the title… until Audi puts this into production, the TT quattro sport concept.
According to Audi’s R&D Chief, Ulrich Hackenberg, Audi wanted to, “demonstrate what the new TT’s technology can do if you take it a step further.” We think they’ve done just that. At the heart of the TT QSC (quattro sport concept is too long to type out over and over again), is a tweaked version of the 2.0 TFSI engine from the new Audi TTS. Just how tweaked? How does 309kW and 450Nm sound? Yes, that’s the same power, and more torque than the 4.2-litre FSI V8 in the B7 RS4, from a 2.0-litre 4-pot.
Peak power is available at 6700 rpm, whilst maximum torque is on tap from 2400-6300 rpm, with over 300Nm being made available from 1900 rpm onwards. This places the 2.0TFSI at a specific power output of 155kW/litre, which if produced, should promptly relegate Mercedes back to the drawing board. Boost pressure from the turbocharged setup peaks at 1.8 bar.
Weighing in at a measly 1344Kg, the lightweight TT QSC is able to catapult from 0-100km/h in 3.7 seconds. This is largely thanks to quattro all-wheel drive, high power output, and the dual clutch transmission.
The TT QSC is aimed at being a track-focused TT, and as such loses and controls that aren’t designed for the driver. This doesn’t mean it isn’t functional though, as it still maintains the new virtual cockpit from the new TT.
With its striking exterior design, and various carbon fibre add-ons, the TT quattro sport concept looks aggressive. We don’t expect to see it in production, however this ties in nicely with a rumoured S3+ that will supposedly have 280kW from the 2.0TFSI engine. We expect a TT+ to debut next year with 280kW and styling cues borrowed from this, while a TT RS will arrive later, still utilising the 2.5-litre 5-pot TFSI generating upwards of 300kW.
