The FIA have revealed that Renault has spent 3 engine development tokens for the development of the RS16B power unit, leaving Renault to continue to have the most tokens available in the remainder of the season.
The arrival of the RS16B power unit was highly anticipated by Red Bull Racing, who likely wanted to see if Renault was really making progress after an extremely difficult 2015 season during which tensions between the two parties reached a highpoint.
With just two upgraded engines available at Monaco, assigned to Red Bull's Ricciardo and factory driver Kevin Magnussen, the other two drivers are set for an upgrade at the Canadian Grand Prix.
Testimony of the improvement is Daniel Ricciardo's pole position at the Monaco Grand Prix.
And that would be the first pole for the R.E.16B, awesome job by the Honey Badger! 👊 https://t.co/MnHd0M0ZEr— Renault F1 Team (@RenaultF1Team) May 29, 2016
