Pascal Vasselon, Toyota Gazoo Racing Europe technical director, mentioned: “The completely different vehicles have completely different efficiency profiles, that’s recognized.

“It’s not an anomaly that the Alpine is slower within the straightline; they’re faster within the corners.

“At Sebring [in March when Alpine won the race] we had been considerably sooner in a straightline however they had been lapping one second a lap faster than us.”
