BBC Sport - Red Bull's Sebastian Vettel spins off in Bahrain F1 test

Vettel in a spin in Bahrain test

Sebastian Vettel spins his Red Bull off the track during day four of Formula 1 testing in Bahrain.

After winning the constructors' championship last year, Red Bull have endured a difficult pre-season but on Sunday morning at least managed 40 laps before Vettel's spin brought out the red flags.

The four-time world champion failed to complete a single lap on Saturday, with his troublesome RB10 car breaking down twice.
