McLaren aren’t too concerned by their lack of performance at the Chinese Grand Prix, which saw Jenson Button and Kevin Magnussen fail to score.
That’s because they’re confident they can make a huge step forward in performance with their latest upgrades, which will filter through over the next few races, according to racing director Eric Boullier.
“I know what is going on [at the the factory], so I know we are on a very good development rate,” he said during a media call.
