Honda Formula 1 chief Yusuke Hasegawa has revealed there was no sign of an engine issue in Fernando Alonso’s engine data from the Belgian Grand Prix, but opted to retire his car as a precaution on Sunday at Spa.
Alonso reported over the radio that he had an issue with his engine, prompting McLaren to call him into the pits and park him up after 25 laps of the race.
Honda has been struggling for either reliability or performance for much of this season, with a number of problems with its power unit resulting in retirements earlier in the year.
However, Hasegawa confirmed after the race that Alonso’s engine data showed no abnormalities despite his report.
“We thought we had the possibility of scoring some points here in Belgium today, so it was disappointing that we finished the race outside of the top 10,” Hasegawa said.
“After starting brilliantly, Fernando then had a tough race overall. He radioed in with what he thought was a problem with the car.
“Although there was nothing showing in the data, we decided to stop the car as a precaution.”
Eagle-eyed fans noted on Twitter after the race that Alonso’s call regarding his engine came not long after a query about the weather, asking if any rain was on the horizon.
Alonso had vented his frustration about the lack of straight-line speed and power from his car earlier in the race, being left a sitting duck while running P7 after a rocket start.
It is not the first time there has been doubt about Alonso’s report of issues with his Honda power unit, with his retirement late on in Bahrain also being suspect.
