Believe it or not these sketches are official patent drawings that proves Audi is well underway with the development of its third-generation Audi TT RS.
Filed in September 2015, the images, leaked last night by car blog Carscoops.com, initially look like a bog standard third-gen Audi TT but differ subtly from the standard car.
Look closely and you might be able to spot a new front bumper that incorporates larger air intakes, while at the rear there’s a new rear apron and bigger air diffuser. Twin oval tailpipes complete the RS look.
The eagle eyed among you might also spot two very faint lines on the front bonnet. According to Carscoop they outline the place where an additional air intake will be placed. Porsche used a similar trick with its 997 and 991 GT3 RS, sandwiching an air intake between where the front bumper meets the bonnet.
There’s much debate about what will power the most powerful TT RS. As we’ve already reported the German car-maker’s 300kW 2.5-litre five-cylinder turbo is at its very limit with the RS3 hatch, so Audi might be forced to either redesign it or take a different approach.
If it favours the latter, Audi could harness its electric turbocharging technology, something it hinted at last May at the annual Worthersee Volkswagen fan meet.
The TT Clubsport Turbo concept revealed there showed a wild Audi coupe that was powered by an all-new 2.5-litre five-cylinder petrol, the new Clubsport gaining two electronically-driven turbocharges that boost power to an incredible 441kW/650Nm.
Coming with standard all-wheel drive this means the TT concept reaches 100km/h from standstill in just 3.6 seconds and has a claimed top speed of 310km/h.
Powered by a dedicated 48-volt electrical system, the compact lithium ion batteries stored in the boot are charged with energy recuperated when coasting.
Interestingly, that show car also came with a conventional six-speed manual instead of a dual-clutch box, this would follow the tradition of the fastest TT RS models coming with manual gearbox.
In any case, all will be revealed this March 2016 at the Geneva motor show when the production-spec TT RS is expected to be revealed.
