Title favourite Lando Norris was fastest for Formula One champions McLaren after a power cut disrupted the first day of pre-season testing in Bahrain on Wednesday. The track action was extended by an hour into the evening to compensate after a power cut plunged garages into darkness and brought out red flags.

Lando Norris got his pre-season testing off to a good start with the fastest time in day one, despite a power outage delaying most of the afternoon's session.
