McLaren was forced to retire from the third day of testing at Jerez after a cooling pressure failure on the car. The team managed 32 laps in the morning session making day three their most productive yet.
The problem forced McLaren to take the engine out of the car, ending the day's testing session.
Day two of preseason Formula One testing saw Sebastian Vettel once again lead the time tables. The Ferrari machine logged 89 laps on Monday and set a best time of 1:20.984 seconds, nearly eight tenths faster than the Sauber piloted by Felipe Nasr.
The second day of testing with the new 2015 cars also produced a fair share of mechanical troubles as one might expect. New cars, changes being made, and the unreliability that is inherently in motor racing all contributed to the three main technical talking points of day two.
Formula One will have its first official test of 2015 at the Jerez circuit in Spain February 1st through 4th. Eight teams are set to attend the testing sessions with Force India, Marussia, and Caterham being the three teams that will not be there.
