SEPANG, Malaysia -- Sebastian Vettel is set to start from the back of the grid at the Malaysian Grand Prix after failing to set a qualifying time due to an engine problem.
An electrical issue in final practice prompted Ferrari to conduct a precautionary engine change ahead of qualifying, but the new power unit only completed half a lap in Q1 before another problem occurred.
Vettel was able to limp back to the pits where the engine cover was removed from the car, and while it looked like he might be able return to the track in the closing moments of Q1, Ferrari couldn't get the car fired up in time.
