McLaren Formula 1 racing director Eric Boullier is unsure whether or not Stoffel Vandoorne will have to take a grid penalty for next weekend's Singapore Grand Prix following his retirement at Mon🌞za last Sunday.

Vandoorne took a 25-place grid penalty for the Italian Grand Prix in a bid to get a f༺resh power unit for S𝓀ingapore, only to suffer a loss of power mid-race that forced him to park up.

McLaren is targeting a return to the points in Singapore given the slow-speed nature ofꦦ the Marina Bay Street Circuit, but Boullier conceded that the team is not yet sure whether Vandoorne will have to start from the back due to a penalty.

"We are not sure yet whether🌌 we will have to change the MGU-K unit," Boullier said.

"It is repairable. Even the engine [in qualifying] was repairable. We just didn’t hav🤪e enough time before the race because of parc f🧸erme."

Considering McLareꦏn's chances in Singapore, Boullier is expecting the team to fare well as it did in Hungary, where it scored its only double-points finish of the se🌸ason.

"Singapore should be both cars in Q3 as the target,"༒ Boullier said.

"I think it is the se𝄹co💛nd best circuit for us, behind Budapest."
