Most teams limited their running to a series of installation laps while McLaren was not able to join the fray, the MP-29 suffering with electrical issues.
Lewis Hamilton was the first driver to take on to the track, and the first to complete a series of significant lap times in the Mercedes W05.

The Brit managed to complete 18 laps of the Spanish circuit until a front wing failure on the following lap curtailed his track time shortly before midday.
At the end of the day, Kimi Raikkonen moved ahead of Hamilton on the charts, setting a 1m27.104 in the Ferrari F14 T.
The Finn also completed the greatest number of laps with 31.
“We had a lot of new things to learn today” – said Raikkonen to www.ferrari.com – “Even if we would have liked to do more laps, I think that for a first day it was alright. Towards the end, when the track was damp, we chose not to take any risks. Now we have a lot of work ahead of us, but all in all, we are pleased with our first day.”

Valtteri Bottas, driving the Williams-Mercedes, was third but almost three seconds to Raikkonen’s time.
Mexican Sergio Perez was fourth in the Sahara Force India Mercedes, some six seconds slower than the Ferrari.

Jean-Eric Vergne was fifth in the Renault-powered Toro Rosso. The STR9 was quick out of the box, but the car stopped early out on the track with a software issue.

Four-time World Champion, Sebastian Vettel managed only three installation laps in the Red Bull Racing RB10.
Like Vettel, rookie Marcus Ericsson managed just one exploratory lap in the CT05-Renault.
As a reference, the best lap time set last year here at Jerez was a 1m17.879 set by Felipe Massa in the Ferrari.
