While it's not expected for another two years, it was revealed last year by Audi technical project manager, Markus Sieward, that the high-powered coupe would utilise a 2.5-litre five-cylinder turbocharged engine
“We will bring an RS as well,” he said.
“It’s obvious because it’s a successful car, people loved it, people ask for the new one. And why not? There’s not reason not to do it.
“It will be a five-cylinder, and it was a successful car for us, it was engine of the year several times. I can’t tell you about horsepower or kilowatts, but it will be more than [the outgoing TT RS].”
When asked whether there would be interest in a TT RS model locally, Audi Australia general manager of corporate communications, Anna Burgdorf, told CarAdvice: "Absolutely. Australians do like their high-end performance cars. For us the whole proliferation of S and RS models...customer appetite is increasing and our role is to fulfil people's desires for sports cars as well".
Given Audi Australia's position as one of the top 15 RS markets in the world, Burgdorf indicated that the local operation doesn't go unnoticed in product planning decisions.
"The growth in our sales and the increase in all of the activities we are doing — we have a voice in a lot of decisions," she said.
"We have seen some interesting concepts in the TT model line. We have made no secret of our desire to increase the number of niche models if there is customer appetite for it."
The outgoing TT RS, which launched in 2009, was powered by a 2.5-litre five-cylinder supercharged petrol engine and produced 250kW of power and 450Nm of torque. It was followed by a final TT RS Plus model, which raised outputs to 265kW of power and 465Nm of torque.
Hints at the new car's outputs could be found in the all-new RS3, which is powered by a re-jigged 2.5-litre five-cylinder turbocharged engine producing 270kW at 5550-6800rpm and 465Nm at 1625-5550rpm. Power is sent via a seven-speed dual clutch automatic gearbox to all four wheels with a modified electro-hydraulic multi-plate clutch AWD system.
Reports out of Europe has indicted the new TT version could get a power bump taking it north of 300kW, though this is unconfirmed.
Both the TT RS and TT RS Plus were available as Roadsters as well as coupes in other markets, though the open-topped version never made it to Australia unlike the coupe. However, Audi Australia has said that this time it will give the convertible "serious consideration".
