(Reuters) - Lewis Hamilton's Mercedes suffered a rare mechanical failure on Friday as Formula One teams wrapped up pre-season testing in Barcelona with Ferrari back on top of the timesheets.
"I'm kind of glad I broke the car at the end of my final run today because it's better to have found something now than in Melbourne," said the triple world champion, who completed 69 laps in the morning.
