Renault have modified spec engine for Spain

Renault arrive in Spain, for Round 5 of the world championship, expecting to provide Red Bull and Toro Rosso with a more effective power unit to do battle with.

Speaking ahead of the Spanish Grand Prix weekend, Renault director of operations, Remi Taffin revealed, "The three week gap has given us an opportunity to look at all the information from the start of the season. We have been flat out to counter the issues encountered early on and we will have a modified spec of engine for this race that should give improved reliability and driveability."

"Barcelona is much more of a traditional circuit than the first four tracks we have visited so far this year. The layout flows a lot more, with high and medium speed corners rather than tight, slow hairpins and long straights."

"It also has changes of altitude as the track follows the contours of the hills. As such, the circuit represents medium difficulty for the Power Units, which subsequently have to deliver good all-round performance across all the parts."

"We are looking forward to Spain to see our hard work in action," added Taffin.

The Spanish Grand Prix has been a happy hunting ground for Renault in the past, winning in Barcelona on 11 occasions. Ayrton Senna won in 1986 with the V6-turbo powered Lotus 98T while the V10 proved dominant between 1991 and 1995, and again in 1997. T

he V8 powered a further four wins, the first coming in 2006 and between 2010 and 2012.
