The three years without a win is the team's longest barren stretch since their absence from the top step of the podium in 1994-96.

That purpose is to develop our team towards our shared ambition: to win," said McLaren boss Ron Dennis. "We'll make no predictions as to when those wins will come," he added. The new MP4-31 car was presented online in a predominantly black livery with some prominent new sponsors in LVMH's sparkling wine brand Chandon and watchmaker Richard Mille replacing the departed Tag Heuer.
