Renault's customer team's, which include Red Bull, Toro Rosso, Lotus and Caterham, are all set to receive a major performance boost for the Spanish Grand Prix this weekend.

The power unit supplier is preparing a "significant improvement" to its software programme which it believes will deliver enhanced "driveability and overall performance" according to head of trackside operations, Remi Taffin.

"The Spanish Grand Prix will be the second stage of the performance evolutions we kick-started in China," he explained.

"While there are not many visible hardware upgrades, there are significant improvements to the software that should further enhance driveability and therefore overall performance.

"Yet again we have also moved forward in energy management and efficiency so we are hopeful our upward trend will continue in Barcelona," he added.

"We have worked hard on these areas in the past three weeks and we therefore go to Spain more confident of a good performance."

The upgrade could give Red Bull the push it needs to compete on a level-playing field with Mercedes as the Barcelona circuit isn't power dependent, therefore Red Bull's chassis and downforce advantage could be enough to see them challenging for the win.
