2023 24H of Le Mans - All you need to know

It's almost time for Le Mans! Tomorrow it's test days and next week we're racing!

This year we see the 91st running of the oldest active endurance race in the world. Its inaugural race was in 1923 which means this year its it’s 100th anniversary, this means it’s the Centenary Edition. the 24 Hours of Le Mans is recognised as the most prestigious and gruelling test for innovations and improvements in motorsport technology.

It’s not only a special edition because of the 100th anniversary, but also because we’re seeing the most cars in the top class in a while. 16 cars will take the start, representing the biggest manufacturers in the world; Ferrari, Porsche, Toyota, Cadillac, Peugeot & Glickenhaus.

Because it’s the Centenary edition, we have a special trophy for the overall winner as well. The 24 Hours of Le Mans, has sealed a partnership with the Monnaie de Paris. The oldest institution in France has thus created a unique Trophy, which will be awarded to the winner of the 2023 24 Hours of Le Mans.

Before the race it has travelled the world to places such as Goodwood, The International Concours of Elegance St.Moritz, Bahrain and more.

History

You might know Le Mans for the running starts. A type that has been used for many types of racing. When the start flag dropped drivers had to run across the track to their cars, climb in, start the car and drive away.

Those kinds of starts were obviously rather unsafe. Drivers would rush to fasten their seat belts to get as fast of a start as possible. This was the reason why it was banned in English racing from 1962.

In 1969 Jacky Ickx decided to walk to his car instead of run, and then took the time to fasten his seat belt. This meant he effectively started last but he still ended up winning the race. In this same race, a driver named John Woolfe died on the first lap after he hadn’t secured his seat belt properly.

This meant it was abolished the following year. Nowadays this type of standing start is only used in Endurance Motorcycle racing. Nowadays at Le Mans, a rolling start is used where cars line up alongside each other at a slow pace and start to race once the green flag is dropped.

The 24H of Le Mans has a rich history, but not a very pretty one in some parts. Back in 1955 one of the biggest tragedies in motorsports occurred. On the straight around the pit wall a huge collision occurred. Usually referred to as the 1955 Le Mans disaster, 84 people died and over 120 were injured. For many countries this meant an immediate ban on motorsport, though a lot of those bans were lifted within a year.

One country, that did not lift the ban, is Switzerland. In 2009 a proposal to lift the ban was defeated by the Swiss Parliament but in 2015 the ban was relaxed for electric vehicles only. Which meant Formula E could race on the streets of Switzerland, even though the ban was technically still there. Now in 2022, at the end of May the ban was finally lifted and motorsport is allowed again in Switzerland.

Please proceed with caution, the Wikipedia page includes one uncensored picture of the incident. The BBC documentary includes footage and pictures and the Reddit post does not include any pictures or videos but does link to the them.

The Track

The track that is currently used is 13.6 kilometers long. It combines the permanent Ford Chicanes, pit straight, under the Dunlop bridge and through to tetre rouge as well as normal everyday roads of the Mulsanne straight through to Indianapolis and Arnage.

The track used to have a 6km long straight where Group C prototypes could reach up to 400km/h. This was changed in 1990 as the FIA required the track to have a straight no longer than 2km to be sanctioned. This is why nowadays two chicanes can be found on the Mulsanne straight. The fastest lap ever on the track was driven by Kamui Kobayashi with a 3:14.791 in 2017.

If you have the time, try to get familiar with the corner names as that’s often how commentators will refer to them.

T1, T2 etc stands for turns 1, 2 etc.

MP1, MP2 etc stands for the Marshall posts. This is important as yellows are often located by race control under the marshall posts.

Points

The race is part of the World Endurance Championship and this means there are also points to score for that championship. The winner of the race will receive 50 points, meaning this race means a lot in the championship.

Points to score:

Women at Le Mans

All credit for the info in here goes to Twitter user @smokingpuppy841 he created these two threads: Women at Le Mans & Why Women Were Banned at Le Mans

This year Lilou Wadoux is one of the women to compete at the 24H of Le Mans. in 2021 year she turned heads when she managed to completely destroy the field in one of the support series at Le Mans. In the French Porsche Sprint Challenge, she beat the field in qualifying by several seconds and then went on to win the race by a huge margin. Within just five years she went from racing in a Peugeot 206 to racing in a World Championship.

Last year she raced in LMP2 but for this year she switched to GTE as she has become a Ferrari Factory driver. This season she already took a win and hopes to do so again at Le Mans.

In 1930 Marguerite Mareuse and Odette Siko become the first women to compete at Le Mans, they finished 7th overall and second in their class.

Odette Siko also finished 4th overall in 1932 and took the win in her class which makes her the best finishing woman at Le Mans. In 1935 a record of 10 women competed at Le Mans, Anne-Cécile Rose-Itier was the best placed of them when she finished 18th overall and third in class.

Unfortunately in 1957 women were prohibited from participating. In 1956 Annie Bousquet, who was known as a spectacular but risky driver, tragically lost her life in the 12 Hours of Reims. As well as driving, Bousquet was also responsible for the preparation work, which involved picking up the car the day before and driving it 500km through the night to the race.

She started the race, but unfortunately, tragedy unfolded when her car would roll on lap 17 after it lost a wheel. She broke her neck and passed away immediately. Following the 1955 disaster which nearly ended motorsport, the ACO were very nervous about another accident. These nerves were only heightened by another tragedy at the 1957 Mille Miglia which saw the Italian government intervene to prevent a repeat.

These worries, combined with Bousquet’s reputation as a risky driver, meant they banned women from the event. A woman hadn’t even competed at Le Mans since 1951, which madethe ban, kind of pointless. The ban was eventually lifted in 1971 and this yearwe will see 5 women at the start again. Rahel Frey, Sarah Bovy and Michelle Gatting share a car in the GTE Am class while Lilou Wadoux also drivers in the same class. Doriane Pin drives in the LMP2 class.

All the women competing at Le Mans this year have already taken a podium in the regular season. While Lilou Wadoux even took two with a 2nd and 1st place. Expectations are high as all these women have the pace to win their respective classes.

Qualifying

Just like last year we will see the Hyperpole format. This sees a one hour session on Wednesday evening where all cars of all classes are allowed on track to set a time. The top 8 cars of all classes (Hypercar, LMP2, GTE AM) at the end of the session move on to the Hyperpole session on Thursday evening. This sets the top of the grid for each class. The remaining order is already decided by the one hour session on Wednesday. During the one hour qualifying session every team is allowed to nominate two drivers that can set a lap time.

Refuelling is forbidden during the Hyperpole.

For the LMGTE Am category, only a Bronze driver can participate in the Hyperpole.

Any car causing a red will have all or some laps deleted

Any car causing a red will not be allowed to rejoin the qualifying session

Regulations

Balance Of Performance

As both the Hypercar class and the GTE AM class have several manufacturers running in the class, there’s a balance of performance in place. BoP” was introduced by the FIA with the aim of achieving a level playing field for the different vehicle concepts.

After an initial grading by the FIA, the performance data of the vehicles are acquired during the races via telemetry in order to adjust the balance of performance. This data input is automatically analysed and incorporated into the “BoP”. The most frequently used means of adjusting the performance level is through adding or subtracting weight as well as increasing or limiting the engine output through a restrictor or boost.

Here’s a short video on BoP

Tyre Allocation

Down below you can see the tyre allocation for dry weather tyres. GTE Pro is crossed out as that class does not exist anymore. Wet weather tyres aren’t limited. This is tyres, not sets. This makes it 14 sets for LMP2 & Hypercar during the race for example. Meaning the tyres will definitely need to be double stinted at times.

Drive Time

The maximum driving time for each driver is limited to 4h for any period of 6h. Every driver has to drive a minimum of 6H across the whole race or the team will be penalised. Every driver is only allowed to drive a maximum of 14H across the whole race.

What's a stint?

A stint is the time the car spends on the track between pit stops. So when tyred are “double stinted” at Le Mans, it means the driver didn't change their tyres during the last stop and only refuelled. Also allowed, is only changing two tyres on the car.

Safety Car Rules

The safety car rules for this year's race have been completely revised. These changes have been made in hope of having less influence on the race. As previously being caught by the wrong safety car could loose the teams a lot of time.

However, these new rules could be a disadvantage for the class leader as it does bring cars closer together. Some critisicse these new rules as they will “manufacture battles at the front.”

When the order is given to deploy the Safety Cars, all marshal posts will display waved yellow flags, and “SC” boards. Pit exit will be closed, and the pit exit light turned red, while the pit entry will remain open.

There will be 3 safety cars, starting from their respective positions, (as can be seen on the track map below). They will join the track regardless of where the overall leader is. All the competing cars must then form up in line behind the Safety Cars no more than five car lengths apart.

Pit exit green light will be turned on after the last car in line behind a Safety Cars has passed Safety Car Line 2, to allow all cars at pit exit to rejoin the track at an appropriate speed until they reach the queue behind that Safety Car.

When the Race Director deems it is safe to proceed with the merging process, the race control message ‘Incident clear – Prepare for Merging’ will pop up. This is followed by the Pit entry being closed Then safety Car B and Safety Car C will proceed to turn on their green lights, then cars which were positioned behind Safety Car B and Safety Car C will overtake their respective Safety Car and will continue as quickly as possible without compromising safety and without overtaking between themselves until they reach the line behind Safety Car A.

Once this is done, a pass around will be started. Any car that has their class leader behind them in the safety car queue will be allowed to pass the safety car.

After this the drop back procedure starts, first in line are the LMP2s. Race control will notify “Drop Back LMP2”, then all LMP2 cars will pull to the right-hand side of the track, then the rest of the cars, will overtake them to take position behind the Safety Car. Then the LMP2 cars will join the line again.

Once this is done, race control will notify “Drop Back LMGTE”. LMGTE cars will drop to the right side just like the LMP2s did. The rest of the cars will overtake them to take position behind the SC.

Once this is done it means that all Hypercars are together at the front, followed by all LMP2s and then the GTEs.

This wave around procedure won't be used in the last 60 minutes of the race.

Red Flag Rules:

During red flags it is not allowed to work on the car, only if allowed by the race director for safety reasons teams are allowed to change the tyres.

Slowzones:

To not immediately neutralize the complete field in case of an accident or debris. There's slowzones in place. The track is divided into 9 zones, when a slowzone is active cars will have to adjust their speed to 80 kph.

It is possible to have several slowzones going on at the same time. For example when an accident happens on the border of a slowzone, it is likely both zones will be deployed.

Penalties:

Speeding in the pitlane during Practice or Warm Up results in a fine of 100 euros for each kph over the limit. Besides that the driver's lap times leading up to the infringement are deleted. During the race the 1st infringement will result in either a drive through (between 60 and 70kph) or a 5 sec stop & go penalty (70kph+). The 2nd infringement will result into another drive through (between 60 and 70kph) or a 10 sec stop & go penalty (70kph+). The third infringement will result into a dsq in both cases.

It is prohibited to spin the wheels when a car leaves its pit, this will result into a stop & go. Aside from that refuelling may only be done when the car is completely on the ground which means tyres can't be changed during refuelling.

Media Guide to WEC

Might seem like a weird one to link but it’s really interesting to read. It goes into further depth about classes, and talks about previous winners etc

Entry List

R/WEC Scratchpad - This is the landingspage, you'll be able to find the scratchpad for practice & qually and for the race here

By this you’re able to catch up on any missed action, penalties and retirements. Obviously it’s difficult following a 24H race in its whole so this is a great way to catch up.

The Classes

The WEC grid consists of three different classes during the complete season, those are Hypercar, LMP2 & GTE. However for Le Mans two subclasses join the race. Neither of those score points for the championship (LMP2 Pro/Am & Innovative Car/Garage 56)

Each class has its own driver requirements, meaning both Amateur drivers and Pro drivers will be on track together.

Hypercar

Red number board with “Hypercar” next to it.

The current top class in endurance sportscar racing is “Hypercar”. This combines cars built to the LMH (Le Mans Hypercar) and LMDh (Le Mans Daytona h) specifications.

The ultimate aim of the ACO, FIA and IMSA is for these two types of car to compete against each other in the FIA WEC and in the IMSA WeatherTech SportsCar Championship and, therefore, to race in both the 24 Hours of Le Mans and the Rolex 24 at Daytona.

LMH (Toyota, Ferrari, Peugeot, Glickenhaus & Vanwall)

These regulations leave scope for a wide variety of architectures and allow a front-axle hybrid system to be fitted. They are designed to a strict set of requirements dictating maximum power, drag coefficient, and weight.

LMDh (Porsche & Cadillac)

In LMDh, the backbone of the car – i.e. the whole car minus the internal combustion engine, the body and the hybrid system – will be supplied by one of four chassis manufacturers: Dallara, Multimatic, Ligier or Oreca.

The driver line ups in this class consist of only pro drivers, with all drivers rated platinum or gold. Technically, lower rated drivers are allowed in the class, but that’s not likely to happen.

LMP2

Blue number board with “P2” next to it.

The LMP2 class features a spec drivetrain and gearbox, using a Gibson V8 producing 400kW, and a selection of three chassis to choose from, of which the Oreca 07 has been the chassis of choice. So much, that every single LMP2 car on this year’s entry list is an Oreca

Driver’s line-ups have to consist of at least one Bronze or Silver driver. When one of the drivers is bronze rated a car is automatically scored in LMP2’s sub class “LMP2 Pro/Am”

A Pro/Am car is easily recognised by the “Pro/Am” sign under the car number

GTE AM

Orange number board with “AM” next to it.

This is the last year we’ll see the GTEs at Le Mans as next year the GT clash switches to GT3 cars.

Although there is no Pro category, the driver quality in GTE-Am is still incredibly high. The grid features factory drivers, young stars, experienced champions, and every level of experience in between. Each car features one Bronze and one additional Bronze or Silver rated driver.

Innovative Car/Garage 56

Black number board with “IC” below it.

Garage 56, is reserved for innovative cars. In recent years we’ve also seen a modified LMP2 car that allowed paraplegic drivers to race. The car was modified and fitted with a braking, clutch and throttle system controlled by a hand-controlled steering wheel.

The Garage 56 entry runs outside the official classification, and will start last no matter where they qualify. This year it will host a Chevrolet Camaro ZL1 entered by the Hendrick Motorsports team for its maiden appearance at the 24 Hours of Le Mans.

This is a heavily modified version of the Next Gen NASCAR that competed in the 2022 Cup Series. The car will be symbolically numbered #24 and driven by Jenson Button, former Formula One World Champion, Mike Rockenfeller, winner of the 2010 Le Mans 24 Hours, and Jimmie Johnson, a seven-time NASCAR Cup Series champion.

Spotters guide

I used to make my own ones but there’s no use in making one myself when @GrosiakMateusz already makes perfect ones. You can find it on spotters.guide. The planned release date is June 6th.

Where to Watch?

Official stream OUTSIDE US ONLY - The Le Mans package gives you access to all WEC sessions (Practice, Qualifying, Warm Up and the Race) with a choice of on boards. It’s a rip-off quite honestly, it costs 13 euros and the platform is prone to crashing. If you’re buying I’d recommend just buying for the rest of the season, usually WEC will put up a discount code - PAID

Multiviewer F1 (Source) - The developer of this app says their goal is to get it ready before Le Mans. It will be integrated with FIAWEC.TV - PAID (Need FIAWEC.TV subscription)

Robin Frijns server, I will be streaming the WEC Coverage, all sessions from qualifying on Wednesday evening - FREE

Eurosport will likely be broadcasting the event in a variety of locales throughout Europe. This will be updated when confirmed - FREE WITH ADS OR PAID DEPENDING ON WHERE YOU WATCH IT

Radio Le Mans will be streaming live radio for every session (Including the test days) - FREE

For American audiences, unfortunately the Official stream is geoblocked for your area. American and English-speaking Canadian audiences can access coverage through Motortrend On Demand. Motortrend should have a free trial so you can try that if needed. - PAID (BUT FREE TRIAL)

Complete Broadcast distribution list

Live Timing

This is Official Livetiming it’s okay, but I recommend using the Timing71 Beta extension

As said the creator of Multiviewer F1 is trying to integrate WEC into the app as well, this would also likely include live timing. If there’s an update on that, i’ll post it.

I hope this is all, but for any questions, my askbox is always open!
