Wolff baffled by engine failure

Hamilton looked to be cruising towards the chequered flag in Sepang on Sunday before an engine fire in the 41st lap brought his race to an abrupt end.

The Englishman was clearly distraught with another reliability issue with his car and did not attempt to hide his disappointment in the post-race interviews.

However Wolff was adamant there is no particular reason why Hamilton has struggled with engine problems and not his Silver Arrows team-mate Nico Rosberg.

"We had a meeting and it's clear he is seeking an explanation," Wolff told Sky F1. "But there are no words and there is no explanation. We had those failures on the car and it is a mechanical sport. It was different failures all the time. As much as he's gutted, so are we, and there's no such thing as anybody having his fingers on any bits."

Hamilton now finds himself 23 points behind Rosberg in the World Drivers' Championship, as both stars prepare for the Japanese Grand Prix at Suzuka this weekend.
