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.

“We’ve had a loss of cooling water pressure and have removed the power unit for inspection. That’s a long process, so it ends today’s running.”

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.

Lotus
For the first time this year Lotus ran their 2015 car, the E23, for the public to see. The Lotus chassis was piloted by Pastor Maldonado and completed 41 laps throughout the day. Lotus finished sixth on the time sheet after putting up a 1:25.802 to stay ahead of McLaren and Red Bull.

Mercedes
Lewis Hamilton was in charge of the Mercedes WO5 for day two and completed 91 laps before a water leak forced the team to retire for the day. According the team website, they are working “to ensure the car is ready for a return to the track tomorrow morning.” The teams hasn’t released any more information as to what caused the leak or if it has been resolved. Mercedes finished the day in fourth.

Red Bull
Daniil Kvyat suffered contact with the wall on his installation lap Monday morning and lost his front wing, something Red Bull apparently wasn’t anticipating. The team had no back-ups available to put on the car, so the Russian was forced to go out to the track without a wing. He managed just 18 laps around Jerez in the RB11 and essentially provided an almost worthless day of testing to his team.

The 2015 Ferrari car for the Formula One series was revealed this Friday. The SF-15T will be driven by Sebastian Vettel and Kimi Raikkonen in the upcoming season. Much like the other cars that have been released, the Ferrari machine has a longer front nose than last year’s cars, per the new regulations in this category.

Ferrari’s technical director, James Allison, said the team is trying to combat the “unacceptably large gap in our performance” last season as compared to the rival teams. The team will be looking for their first win since the Spanish Grand Prix in 2013 after going win-less last season.
