Fernando Alonso will arrive in Malaysia without facing the immediate prospect of grid penalties after Honda confirmed his car's engine survived the heavy crash which prematurely ended his Singapore Grand Prix.
Alonso missed out on what he felt was at least a podium finish after being caught up in the first-corner collision involving Sebastian Vettel, Kimi Raikkonen and Max Verstappen. The contact forced the Spaniard to retire from the race.
Damage to the engine would have required extensive changes and prompted a big grid penalty, but Honda's investigations have concluded that will not be necessary.
"Regarding Fernando's Singapore power unit, we were concerned that it may have been irreparably damaged, but fortunately after a thorough check back at the Sakura factory we can confirm it is okay to be re-used," Honda chief Yusuke Hasegawa said.
