Triple world champion Lewis Hamilton will be hoping they can come up with an overnight solution after the championship leader was only sixth fastest in a second session led by Ferrari rival Sebastian Vettel.
Hamilton took full advantage of Vettel's calamitous start at the Marina Bay Street Circuit to win the race extending his lead in the drivers' championship from three points to 28 with six races remaining.
Despite starting from last on the grid, compared to Hamilton who will see a clear road ahead of lights out, Vettel believes that he'll be able to fight back and aim to make up positions of the race tomorrow, but admits it feels a shame that issues occurred when his auto felt positive.
Hamilton was clearly surprised to be on pole after a torrid weekend where he had failed to be quicker than fifth in any practice session. "The vehicle felt good".
Sebastian Vettel is the only driver on the current grid to have graced the top step of the Sepang podium four times.
Vettel's engine had already been changed to a new one before qualifying after a similar gremlin in final practice Saturday - only for the new unit to fail.
Hamilton's team-mate Valtteri Bottas, who was seventh fastest overall at 0.043secs behind the Briton, was 0.7secs slower than Vettel on average on their race-simulation runs in the second part of the session. "Tomorrow is a long race and it will be tough for tires".
"In Monza we didn't do our best and equally Mercedes were very strong.it's mostly in Singapore where we didn't race. For me, F1 is all about speed, loud sound and unpredictable results, and Sepang is well known for its toughness and challenging weather", said Rajamohan, who is involved in the book and stationary business.
"It's a nice circuit", he continued, "but the only thing you see is the airport, the hotel next to the airport and the circuit. I don't know whether he feels pressure".
"I think it's OK".
As a result, Hamilton reverted to the old specification of auto while Valtteri Bottas ran the new.
Vettel saved Ferrari's blushes but, as if Ferrari's luck could not get any worse, Williams driver Lance Stroll smashed into the side of his auto on the warm-down lap, cutting it nearly in half. The lights went off, we did our start, everyone was trying to do his start, and with the way it happened it ended up really bad for all of us.
