Stoffel Vandoorne is facing another grid drop at the Singapore Grand Prix with McLaren-Honda mulling over whether to introduce yet more new engine parts.
Honda's introduction of their 'Spec 3.7' engine at Monza resulted in a double DNF for the team with both Fernando Alonso and Vandoorne forced to retire.
The duo recently took engine penalties at Spa and Monza in order to be able to start the Singapore Grand Prix, a race expected to suit the MCL32 chassis, on an even footing, but Vandoorne could need a new MGU-K fitted.
“We’ve worked hard to try to avoid incurring any penalties which could halt our progress in Singapore,” said McLaren racing director Eric Boullier.
“We hope that following Stoffel’s retirement in Monza we won’t have to use any new power unit elements, although this is yet to be officially confirmed.”
Vandoorne has already used 10 MGU-H and turbo charger components and seven ICE and MGU-K components. The season limit is four before penalties come into effect for each new engine part introduced.
