It’s day 4 of testing LIVE from the Jerez circuit in Spain. Stay up to date with all the action from all the teams and drivers participating in the first official test of the 2015 Formula 1 season. The first 3 days got off to a good start from World Champions Mercedes with a large haul of laps. Ferrari took top spot on the time sheet with Sebastian Vettel at the wheel. McLaren however were consigned to the garage for the most of the day with Fernando Alonso only completing 6 laps and Jenson Button a mere 6 on day 2. With only 32 laps completed on Tuesday they have a lot of work to do before Melbourne.
