Hamilton unlikely for a repeat of Bottas' "very unusual" engine failure

Mercedes boss Toto Wolff has stated that Lewis Hamilton is unlikely to suffer with a "very unusual" engine failure that Valtteri Bottas had in practice on Saturday.

It was a hydraulic problem for Bottas just before the end of FP3.

"We've just heard that Valtteri's reliability issue shouldn't affect Lewis' engine," Wolff told RaceFans on Saturday. "Nevertheless, it is a reminder how fragile the situation is and how much everybody is pushing in order to extract performance.

Wolff confirmed that Bottas' engine will have to back to the team's headquarters to be assessed after its unusual failure: "The failure we have seen on Valtteri's engine is a failure we haven't seen for many years.
