Hamilton had to withdraw from the Turkish Grand Prix grid after swapping key engine components for the fourth time. The reigning world champion may have to start over in one of the next races to allay concerns about the reliability of his engine. This would mean a new grid penalty. A rider can use three motorcycles per season without penalty.
His teammate Valtteri Bottas is already working on his sixth bike. He had to return to the grid at the United States Grand Prix last Sunday. “It was painful for Austin’s race, but he will reap the benefits of the improved engine in future races,” said Vowles.
Hamilton is engaged in a fierce battle for the world title with Max Verstappen. The season has five more races and the Dutch Red Bull driver leads the way with a 12 point lead.
