McLaren Formula 1 team boss Andrea Stella says the team needs to step up its development program if it is to catch Mercedes and keep up with the other top teams.
McLaren has been consistently behind the leading Mercedes cars this season and in recent races it saw both Ferrari and Red Bull make bigger swings with rafts of aerodynamic upgrades. McLaren didn't bring significant upgrades to this weekend's Austrian Grand Prix, with Lando Norris and Oscar Piastri qualifying sixth and seventh respectively - four tenths behind polesitter George Russell over the Red Bull Ring's short lap.
