McLaren are bringing a raft of aerodynamic updates for the MP4-25 to the Spanish Grand Prix as they strive to keep in touch with Red Bull and Ferrari.
Chief engineer Tim Goss explained the changes to the car this weekend:
We’re bringing a significant upgrade to Spain.
We’ve got a new front and rear wing, both are reasonably major changes compared to the last version.
There are also some subtle changes in to the floor at the rear of the car and other areas. It’s actually some of the subtlest changes that are the most significant in terms of the car’s performance.
He feels the team have made progress on qualifying pace since the start of the season having been surprised by Red Bull’s performance in the opening round:
After the Barcelona test in February we were quite confident. But we were taken aback at Bahrain – we were some way off the pace especially compared to Red Bull.
At Malaysia we brought a significant change and we were really expecting to be competitive in qualifying. But due to the mistakes we made with the weather we never really got to demonstrate it.
At China barring the slip-up Lewis had in qualifying we’ve proved we’ve closed the gap. We were probably two to three tenths of a second off Red Bull in China.
How we do in Barcelona depends on the changes we made to the car. We’ve made decent step but expect other teams will have to – obviously Ferrari have their own drag-reducing rear wing now too.
