Red Bull might build own F1 engines in future
Currently, the Austrian team uses customer Renault units, with the more competitive Mercedes-Benz units not available due to McLaren's power of veto.
When reports recently suggested Volkswagen might enter F1 as an engine supplier, the closely-aligned Red Bull was mooted as a natural partner.
"We're staying with Renault," the energy drink company's chief Dietrich Mateschitz said in an interview with Kleine Zeitung newspaper.
"But we are on stand-by for an interesting partnership," added the Austrian billionaire.
"And even the idea of developing our own engine, I think, is no longer so absurd," added Mateschitz.
He is probably referring to the sport's talks about reverting to a lower cost and more road-relevant engine formula one after 2012.
