In an interview with Australian magazine, Motoring, division boss Stephan Winkelmann said the renewed focus on electric vehicles and slowdown in the sales of oil burners in light of the ongoing emissions saga, could lead to the eventual scrapping of S and RS models fitted with TDI engines.
"There are a lot of countries where diesel is not a central purchase reason, Asia and North America for example. So it’s not useful for us to have only one car and one engine to offer – it lowers the opportunities we could offer,” Winkelmann said.
"Due to the fact that we need to do more ‘world cars’ and that the budget is limited, diesel would be very much a second priority – it’s not our priority."
He also stated that the company is under pressure to follow current automotive trends in combining sportiness with sustainability, saying core values are now more important than ever.
"We have to explain to our customers the differences between the RS model of today and the electric model they will be able to buy [in the future],” the former Lamborghini boss continued.
"Electrification must come, but if we are to stay credible, it must come under the Audi Sport banner. We won’t have an extra brand, and I think that if you look 15 or 20 years from now some of those other brands will have gone away".
At present, only two S models, the SQ5 and SQ7 make use of TDI engine, although speculation has mounted that both could spawn RS models in due course.
