McLaren’s new MP4-29 failed to complete a lap at Jerez on Tuesday, leaving Jenson Button twiddling his thumbs.
Although the car had been fired up successfully in the factory, the team had trouble getting it to run properly on Monday night, and despite working on the problems, it ran out of time on Tuesday.
A team statement confirmed: “Despite firing up successfully at the MTC last week, the car was predominantly affected by electrical issues during the day. The subsequent dismantling, inspection and re-installation of several major components ultimately meant we were unable to conduct any running today.
“We’re reinstalling key systems on the car overnight, with the expectation that Jenson will begin the car’s installation program tomorrow.”Formula 1, Jenson Button, McLaren
