Sebastian Vettel topped the first day of Formula One's pre-season after Ferrari made an impressive start to testing.
Vettel was 0.4s seconds quicker than the next fastest driver, Carlos Sainz in the McLaren, and completed the most laps with a total of 169. Vettel racked up a string of laps in the 1:18s towards the end of the morning session, using Pirelli's new C3 compound (the equivalent of last year's soft tyres) to set the fastest time.
