Le Mans Leaders Lost The Race In The Last Hour Because The Team Changed The Wrong Tyre

When a puncture was detected on the leading No.7 Toyota in the final hour, a problem with the tyre pressure sensor led the team to change the wrong tyre

The No.7 car of Mike Conway, Jose Maria Lopez and Kamui Kobayashi had dominated this year’s 24 Hours of Le Mans when the car had to make an unscheduled stop after a slow puncture was detected. Lopez came in, had the offending tyre changed, only for another puncture to be discovered on the outlap, resulting in a slow journey back to the pits.

This cost them the lead - and ultimately the win - to the sister No.8 car driven by Fernando Alonso, Sebastien Buemi and Kazuki Nakajima. However, it wasn’t just an unlucky coincidence that the car got two punctures in two laps, but actually an error with the equipment. Toyota Gazoo Racing technical director Pascal Vasselon told Sportscar365 after the race:

“They picked up a puncture which the sensors in the car have already detected. They have detected the wrong tire, so it told the team that it was the front-right, but it was the rear-left. So we changed only the front-right, and then when they restarted, we realized immediately that the puncture tire was still on the car. This is why he did the second lap slow.”

Vasselon added that the No.7 crew “fully deserved” the win, while team boss Rob Leupen admitted that there had been talks to issue team orders in order to restore the victory. He told Motorsport.com:

“We thought about doing something, but that wouldn’t have been correct. We talked it through with the drivers and I think we did the right thing. Le Mans chooses its winner again.”

It was an unfortunate turn of events so late on, but it begs the question of why Toyota changed just one tyre instead of all four - something Leupen said the team would have to look at. It would have taken slightly longer, yes, but it probably wouldn’t have cost the car the lead or the win. Even Alonso (who knows a thing or two about losing things at the last minute having lost three F1 championships in the final race) said that the No.7 car deserved to have won.

The race also brings a close to the 2018/19 World Endurance Championship ‘super season’, with Alonso, Buemi and Nakajima being crowned world champions. Alonso now has two Le Mans wins from two starts and has become only the second driver in history to win FIA World Championships in two different series (the other being Petter Solberg, who has titles in the WRC and World Rallycross).

Meanwhile, Nakajima has become the first Japanese driver ever to win an FIA World Championship. So, there’s still plenty of good news for Toyota, but it seems like the late change to the race result has put a bit of a dampener on things…

All because the TPMS system had a Gremlin called Atoyot on it and he hit it with a big hammer causing it to freak out twice and spit out wrong readings to the car computer and causing the engineers to freak out and have kittens….

This is probably a good example of why they couldn’t beat Audi and Porsche

It was only pure luck that Porsche won in 2017. Toyota led the entire way pretty much. And remember, Porsche have been in the game way, way longer…
