First official day for the 1.6T V6 engines and the new 2014 F1 cars. There were plenty of tasks and problems on all teams to get their cars running. Many teams didn't come out until the end of the day, when it started raining, and only for a few laps: installation lap and not much else.Lap times were at least 9-10 seconds worse than the best lap times you can remember in recent years at Jerez.
