Jenson Button will start tomorrow’s Canadian Grand Prix from the back of the grid after failing to take part in Saturday’s qualifying session due to an engine problem.
McLaren has endured a difficult start to the season with the new Honda power units, encountering a number of technical problems that have limited the team to just one points finish.
Button’s teammate, Fernando Alonso, suffered a problem with his engine in FP3 that looked set to sideline him from the session before the team managed to repair the issue and send him out.
Ahead of qualifying, McLaren confirmed that Button had suffered a failure on his ERS system towards the end of the practice session and that he would not be able to take part in qualifying.
The MP4-30 slowed in the first sector, forcing the 2009 world champion to park his car at the side of the circuit towards the end of the session.
JB’s car suffered ERS-related failure towards the end of FP3. Our engineers are looking at data, but sadly his car won’t be ready for quali.

As a result, Button will start the race from 20th position at the back of the grid on Sunday. Toro Rosso driver Max Verstappen is due to drop to P19 thanks to his 15-place penalty, but will start behind Button given that the Briton did not technically qualify for the race.
In the sister car, Alonso finished 13th in the session after failing to make it through Q2, leaving McLaren with an uphill struggle if it is to score points in the race on Sunday.
