Audi executives have confirmed both that the third-gen Audi TT Roadster will officially debut at October’s Paris motor show, and that the next Audi TT RS will use a five-cylinder turbo – ending rumours of a pumped-up four.
Speaking at the international launch of the Audi TT coupe, head of interior design Artur Deponte let slip that the TT Roadster (spied below in testing at the Nurburgring) will in fact be revealed next month at Paris.
“The TT has always had its brother, its relation in the roadster and it will debut in Paris,” told Deponte, who was speaking about the repositioning of the climate controls inside each of the five air vents in the new TT.
Deponte has been explaining how to integrate a neck warming feature into the repositioned climate controls, which are now located inside each of the five face-level air vents in the cabin.
He mentioned that seat heating buttons have been grouped on each of the far vents specific to each of the front passenger because each seat heater was also specific to each side only.
The challenge, he added, was to also integrate the neck warmer function for the forthcoming TT Roadster.
“We have this topic with seat heating, and we have this air vent for your neck too – and you should be focused only where that could be,” he said.
“Maybe it could be integrated in a logical way, too, you will have to see…”
While the TT Roadster will debut next month, the next generation of TT RS flagship can be expected in around three years, utilising a 2.5-litre five-cylinder turbocharged engine now confirmed by technical project manager Markus Siewart.
“We will bring an RS as well,” Siewart began. “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].”
Emissions regulations have plagued development of the turbo five, however, forcing a near-complete redesign of the 2.5-litre powerplant.
“It is a big reason [emissions],” he contines. “It is not easy for the engine, but it is possible. It is a question of development.
“You have to do relatively big changes inside the engine to meet emissions. We have to do that because of emissions. We look to be lighter and we look to be more powerful.”
But Siewart “wouldn’t recommend” going small in capacity than 2.5 litres. The outgoing TT RS, which launched in 2009, three years after the second-generation TT lobbed, produces in its final TT RS Plus incarnation 265kW of power and 465Nm of torque.
In terms of timing, Siewart says “I would look to the second generation … the gap between the second generation is something that would make sense.”
That strongly indicates a 2017 start for the next-generation TT RS.
In terms of technology, Siewart points to the Audi TT sport quattro concept shown at the Geneva motor show in March.
While it utilised a 309kW 2.0-litre turbo four-cylinder – sparking rumours of that engine in the TT RS – it also showed off lightweight carbonfibre and other weight-saving advancements. The technical development boss says that is “maybe a hint of the future of what we can do, but nothing is confirmed.”
“I would recommend to wait a little bit. The RS is a car which will bring some technical figures with it. We will have a bit of a surprise for it.”
