McLaren says upgrade delivering "more than expected"

The Woking-based team introduced a new front wing on Fernando Alonso's car from the United States Grand Prix, which is based around a concept that it wants to carry forward into its 2018 design.

Fernando Alonso hailed the step in Austin as ‘great’, and its potential was made clear in qualifying in Mexico last weekend when the Spaniard managed to set the fastest overall middle sector time in Q1.

Racing director Eric Boullier admitted that the pace had come as a bit of a surprise, but reckoned that it was proof the update was bringing more speed to the car than had been anticipated.

“Let’s say it is a little bit better than we were expecting,” Boullier told Motorsport.com about the speed shown in Mexico.

“It was a surprise. We were not expecting to be that competitive, but if you put everything relative apart, the new full package that we introduced on Fernando’s car last weekend looks like it delivers a little more than expected – which is good news. Hopefully Stoffel [Vandoorne] will have it in Brazil as well.

“It is good as a reference as well, because it is part of next year’s car, and it is good to know where we are and what we can do.”

Best car

Alonso’s speed in qualifying in Mexico left him claiming that McLaren had the best chassis in F1 at the moment.

Boullier was reluctant to back such a bold claim, as he suggested that different characteristics of the McLaren and the Red Bull meant it impossible to rank them overall.

Asked about Alonso’s comment, Boullier said: “It is nice to hear, because this is obviously the best reward a team can have.

“When you are a driver of Fernando’s calibre and he is complimentary of the chassis, then it makes me proud of the team and obviously I am proud of what we achieved.

“But I think every race is a bit different. The car characteristics are different between our car and the Red Bull car for example, so we know what is our weakness versus the Red Bull car, and I am sure they know the inverse.

“That means we still have to work. But it is good. And after we reset the car concept three years ago, to have caught up with the top teams is quite an achievement, I would say.”
