Sebastian Vettel certainly hasn’t enjoyed the most productive of tests, having completed just 11 laps over two days of testing in Jerez.
The reigning champion completed just three laps on Tuesday after the team found a part had been installed incorrectly.
The team had hoped for a far more successful second day, but a reported ERS battery issue on the Renault engine left them garage-bound.
“Obviously we’ve not had a lot of running and have a few problems to sort out, but with such big rule changes it is usual to have some teething problems,” said Vettel. “That’s what tests are for, to sort those issues out.
“The next two days will be important to get some track time to prepare for the tests in Bahrain.”
Vettel has therefore cancelled his evening media arrangements and will fly home tonight, handing the car over to Red Bull team-mate Daniel Ricciardo for what the team hope will be a more successful days running on Thursday and Friday.
The failure brings into question Renault’s readiness, with Renault-V6 powered cars (Red Bull, Toro Rosso and Caterham), having completed just 19 laps on Tuesday.
