Red Bull's Chief Advisor Dr Helmut Marko has revealed that his team is not alone in suspecting certain irregularities at Ferrari's powertrain, as other competitors are also suspecting the legality of the Ferrari unit.
Ferrari, with the help of the raw power of its powertrain, won races at Spaj and Monza, and the superiority of the Ferrari's long-haul powertrain soon aroused suspicion of competing teams.
Red Bull team boss Christian Horner has revealed that his team has already asked FIE authorities about the legality of the Ferrari powertrain.
We have repeatedly asked the FIO questions about the Ferrari powertrain, as we have certain doubts. No answers have been received yet.
In an interview with Auto Bild, Helmut Marko revealed that the Red Bull team is not alone in their suspicions:
We're not the only ones pointing their finger at a Ferrari. Mostly these are Mercedes and Renualt. In fact, their power on the plains is unimaginable to everyone else.
