The 94th 24 Hours of Le Mans saw the No. 7 Toyota GR010 Hybrid, driven by Kobayashi, Conway, and De Vries, take the checkered flag. However, the victory was far from straightforward, as the Japanese machine battled a secret sensor issue that cost it up to 8 km/h in top speed, a significant disadvantage on the demanding Circuit de la Sarthe.
A Masterclass Under Intense Pressure
This Sunday, the checkered flag signaled the win for the No. 7 Toyota GR010 Hybrid, but the crew certainly didn’t have an easy time. Behind the resounding success lay a persistent technical problem, revealed after the race by David Floury, Toyota’s technical director. The winning car was forced into “safety mode” multiple times, directly impacting its performance, particularly on Le Mans’ long straights where every tenth of a second counts.
The No. 7 Toyota GR010 Hybrid had to contend with a troublesome sensor issue.
A Tricky Sensor, a Headache for Engineers
The problem began during the night between Saturday and Sunday. A sensor, malfunctioning and generating “noise” according to Floury, was disrupting the FIA’s measurements. This instability forced the team to switch to a default mode, then reduce power. Even when the sensor regained partial functionality, it triggered a cascade of alerts, necessitating careful management. “I don’t know exactly how much power we lost, but at certain points in the race, we had a 6 to 8 km/h difference between the two cars,” the technical director stated. A significant gap that could have been costly in such a close duel.
A Race of Pitfalls from the Start
The victory was no stroll in the park. In the early hours of the race, the No. 7 Toyota suffered a slow puncture, threatening to cost it a full lap. This early incident complicated the team’s strategy.
