24 Hours of Le Mans: What is Scrutineering?
On Sunday 9th and Monday 10th June the traditional Scrutineering and Administrative checks or ‘Pesage’ will kick off the start of race week for the 24 Hours of Le Mans.
All 186 drivers and 62 cars entered for the twice-round-the-clock race on 15/16th June must present themselves at the Place de la République in the centre of Le Mans.
The event provides a unique opportunity for real fans as well as passers-by to get a close-up look at the cars and the competitors who will be on the grid for the start of the most legendary endurance race in the world.
But what gets checked under the big white tents?
Following a clearly marked-out route, the cars are checked at three different posts to make sure they conform to the regulations.
The first is where the main dimensions are measured (width, length, overhang, wheelbase, height of the wing and the fin (for prototypes) and so on. Scrutineers use 3D scanners that reproduce the surface of the car to check dimensions such as the wheelbase.
The cars then pass onto a platform which can be raised so that the underneath of the car can be checked. The platform is equipped with lasers and mounted on scales so the weight of the car can be verified.
At the final post, bodywork is partially removed for the inspection of safety features such as fire extinguishers, belts, circuit breakers, indicators, hybrid safety systems etc), the fuel tank and the engine oil catch tank as well as the conformity of certain key elements such as placement of decals transponders, dataloggers and the leader light system.
The data acquisition system in each car is scrupulously tested as is the in-car marshalling system which, via a special black box, tells the drivers in the cars about what’s going on around the circuit and the actions carried out by track marshals. In total, the operation lasts around 50 minutes per car.
And what about the drivers?
They too are subject to checks, and all must present their licenses and every part of their equipment from race suits to helmets and everything in between to make sure they conform to FIA regulations.
Once this is done, official photographs are taken, and media work is carried out before they meet up again with their cars and team personnel for the big group photo which serves as a record for each participation and which often appears in the annual Le Mans Yearbook.
Scrutineering will take place on Sunday 9th June from 14h00 to 19h00 and will continue on Monday 10th June from 09h30 to 18h00. A timetable for the event can be found HERE.
