Bahrain Grand Prix – Fernando Alonso will require a power unit change on his McLaren after suffering an MGU-H failure in qualifying.
The Spaniard had progressed to Q2, but before he could complete a lap in the second qualifying session his power unit gave in, leaving him just fifteenth.
“I think until the last corner it was half a second better than my Q1 time, then I went on the throttle and there was an issue in the power unit,” he said.
“That hurt, because we had a chance of being a couple of places up, and tomorrow we’ll have to fit a new power unit, which won’t have the perfect settings or calibration.
“The first lap the engine gets will be the formation lap, so it won’t get any warm-up, we won’t get any laps to tune it, and we’ll probably therefore have an even tougher race than we’d expected.
“It’s not the ideal situation, but there’s nothing we can do just now, so we’ll see tomorrow what we can do.”
This will mean Alonso moves onto his second power unit for the season, three races prior to when most teams are expected to make their first power unit change.
Drivers can use four engines in 2017 before grid penalties start to be applied.
