Abiteboul: Fuel is leaving Red Bull behind

Cyril Abiteboul believes that Red Bull are not using their engine upgrade to its full potential, and it is down to the fuel they put through it.

Red Bull have a deal with Exxon/Mobil, while both Renault, and their other engine customers, McLaren, use BP/Castrol fuel and lubricants.

This means that when Renault develop the engine, less time is used to develop it using Exxon/Mobil products, as the majority of the time is focussed on using BP/Castrol for the development.

BP/Castrol brought an upgrade to their fuel and lubricants package for the Spanish Grand Prix, which has seen both Renault and McLaren improve over the last three races.

Renault Sport F1 boss Cyril Abiteboul believes that Red Bull were missing out on that extra bit of pace in Montreal last weekend.

“I was secretly hoping that Red Bull would have the pace to win,” Abiteboul told Autosport. “They were very, very close to that, but not quite there. We have more to come, and they could have more to come from the fuel.”

Abiteboul went on to say that although all three teams have the same engine, and with it comes a guarantee of equity, they have no say over the fuel supplier.

“That is something that is clear. We can guarantee an equity of performance of what is in our control, which is hardware, which is software,” he continued.

“Not anything other than the, like fuel, because they elected themselves for strategic and commercial reasons to go for their own partner, which we appreciate, and we support by homologating their product,” Abiteboul added.
