Red Bull brought a disastrous first pre-season test to a close on Friday after completing just 21 laps across the week.

Daniel Ricciardo was on track early on the final day but after completing five laps overheating issues saw the team cut holes in the sidepod. However, Ricciardo only went out for two more laps before returning to the garage and the team confirmed early in the afternoon that it would not run again at Jerez.

Sebastian Vettel was driving the car on the opening two days but managed just 11 laps in total, with Ricciardo only adding three on Thursday before another frustrating final day. Issues on Wednesday were attributed to the Renault power unit, but the solutions attempted on Friday suggest it's a packaging issue with the RB10, as the Renault-powered Caterham managed 45 laps on the final morning.
