Reigning Formula E champion, Sebastien Buemi, faces an uphill struggle to retain his title after a disastrous Saturday in Montreal.
It all started to go wrong in free practise two, when Buemi managed to hit both entry and exit barriers to the final chicane destroying one of his race cars. Things took a turn for the worse when the e-dams team discovered damage to the car's battery, resulting in a ten place grid penalty. In the race Buemi managed to climb to fourth place - more of that later - only to be disqualified when the repaired car was found to be 4kg underweight.
With championship rival Lucas di Grassi taking points for pole position and the race win Buemi lost the championship lead too.
After the race Buemi was filmed in heated arguments with three other drivers. Unlikely to put them in a frame of mind to be kind to him in the season finale tomorrow.
Still, Buemi has been the class of the field in Formula E almost since its inception, so even with an 18 point deficit it would be a fool who writes him off tomorrow. A maximum score of 29 points would heap the pressure on di Grassi, who is likely to endure a fraught afternoon if he is going to stop Buemi from retaining the title.
