Canada GP: Drive through penalty for Button

MONTREAL, Canada - McLaren's Jenson Button, already starting last at the 2015 Canadian GP  after missing qualifying, collected an additional drive-through penalty after the team changed parts of his Honda power unit.

The team said on Twitter: "JB's MGU-H and turbo have been replaced, hence he will have a drive-through penalty in this afternoon's race."

Butto scored misfiring McLaren's first points of the season in Monaco when he finished eighth.

MCLAREN WOES CONTINUE

In 2011, he won a rain-affected race despite being in last place when the race was re-started. After passing Sebastian Vettel's Red Bull on the last lap, he described it as possibly the best victory of his career.

Button's team mate Fernando Alonso, who has yet to finish in the points in 2015, starts 13th but McLaren have no illusions about the task ahead.

Racing director Eric Boullier said on Saturday (June 6) that McLaren, who have not won a race since 2012, needed to improve in all areas.

Eric Boullier said: "If you want to win you have to be the best in terms of aerodynamics, vehicle dynamics, chassis, driveability, so we have to improve everywhere.

"We are lacking downforce to be at the front...so we have to work on this to make the car better."
