PORSCHE has admitted to turning its back on entering Formula One due to the sport's lack of relevance for their roadcar programme.
The German manufacturing giant would naturally be a welcome addition to F1, but from next year will instead compete in LMP1 sportscars using hybrid power.
With comments that will give motor sport's world governing body, the FIA, and F1 supremo Bernie Ecclestone food for thought, Porsche's head of R&D Wolfgang Hatz told Autocar: "We are a sportscar company.
"Porsche has always lived for the transfer of racing to production cars.
"For that reason it was clear two or three years ago we had to be back in high-level motorsport, and it was a choice between top-flight sportscars or Formula One.
"The final decision was the only logical one. F1 was an alternative, but the road relevance is not there.
"Also, there is a lot of publicity around politics and tyres, but not so much about the engines and chassis.
"The aero, too, is incredible, but so extreme that it cannot result in any development in our road car understanding."
