Renault expect boost from new fuel and aero tweaks

Speaking ahead of the Spanish Grand Prix weekend, team chief Cyril Abiteboul revealed, "The start of the European season now needs to see a consolidation of that performance [in Baku]."

"We will be helped in Spain by a step on the engine side with new fuel and some aero tweaks to reflect the characteristics of the track."

"We hope this to be a move forward, but we also recognise that many other teams will bring upgrade packages too and Barcelona is well known to everyone," added Abiteboul.

Sources close to Renault believe the fuel alone could be worth a couple of tenths around Barcelona, but only time will tell if this indeed will be the additional performance they find and if their rivals stand still between now and the race weekend in Barcelona.

Renault are enjoying a strong start to their season and can lay claim to being the next best team behind Mercedes, Ferrari and Red Bull - the latter team also using Renault engines, albeit badged TAG Heuer.

Red Bull use Mobil-Esso as a fuel supplier and the other Renault powered team, McLaren utilise Petrobras.
