McLaren is planning to introduce another “major upgrade” package before the end of the season.

Having applied a raft of updates in Singapore, McLaren scored more points than all teams bar Mercedes and Red Bull at the following Japanese and Russian rounds, reclaiming fifth position from Force India in the process.

McLaren’s Racing Director, Eric Boullier, says that rather than a final push to further improve the outfit’s overall classification, developments over the remaining three races will be geared towards the 2015 campaign.

“We have another major upgrade coming before the end of the season,” explained Boullier during a McLaren-Mercedes phone-in. “It is not designed to bring an advantage for the double points [season finale in Abu Dhabi], it is more about building the foundations for the future. 100 per cent is applicable to next year’s car.”

Boullier agrees that reeling in Ferrari – 45 points clear – remains feasible, but says it is not a specific target.

“If the performance on our car is good and we can deliver some strong races like in Russia we will see if we can take back another championship position. I would be delighted to,” Boullier added. “[But] I don’t think we have a clear target this year other than rebuilding the team and getting ready to fight back as soon as possible.”
