À l’occasion du #Rolex24 2020 à Daytona, les deux organismes ont dévoilé le principe directeur de cette plateforme – l’introduction en tant que catégorie supérieure de compétition de LMDh, qui sera éligible à la fois au championnat du monde d’endurance (WEC) et au championnat de voitures de sport WeatherTech de l’IMSA.

Le core du partenariat consiste à combiner la prochaine classe Hypercar Le Mans 2020 et une nouvelle formule appelée LMDh qui sera mise en pit-lane puis sur piste en 2021. L’Hypercar et la LMDh courront ensemble dans une seule classe mixte, qui repose sur la fameuse Balance of Performance.

“This announcement today is the crucial starting point for a joint endurance racing future, supported by both the ACO and IMSA,”

“The platform represents the convergence achieved by both organizations which is a great success story for endurance racing. A manufacturer will soon be able to compete in the top category of two championships, the FIA WEC and the WeatherTech Championship. We can’t emphasize enough, as it’s exceptional, how many opportunities this long-term sporting and marketing vision will open up.”

Pierre Fillon, Président de l’ACO

LMDh ?

La formule LMDh, qui signifie Le Mans Daytona (et attend encore la confirmation de la définition du « h »), est prévue pour un déploiement échelonné. LMDh fera ses débuts en septembre 2021 aux côtés de l’Hypercar en Europe, et à l’IMSA, LMDh remplacera la formule DPi actuelle en janvier 2022 au début de la nouvelle saison du WeatherTech Championship.

“When my father, Bill France Sr., brought the first Daytona Continental sports car race here to Daytona International Speedway back in 1962, he wanted to bring together sports car drivers, teams and manufacturers from around the world,”

“With the ACO, IMSA and manufacturers aligned, today’s announcement proudly takes my father’s vision to the next level.”

Jim France, IMSA co-founder and chairman

Cette plateforme commune répond aux souhaits de nombreux constructeurs : la possibilité pour les constructeurs automobiles de concourir avec la même voiture aux 24 heures du Mans, aux Rolex 24 de Daytona, au SuperSebring ou à Spa-Francorchamps, au Motul Petit Le Mans ou encore à Silverstone, sera bientôt une réalité. L’ACO et l’IMSA ont établi ensemble les bases d’une réglementation commune pour régir la nouvelle catégorie LMDh.

“The big winner today is endurance racing, as the door is now opened to many additional competitors to compete at the highest level on both sides of the Atlantic with the same car,”

“The two sanctioning bodies should be congratulated for their vision and spirit of collaboration. Le Mans Hypercars and the new LMDh cars racing together at Le Mans or Daytona will be an incredibly exciting prospect for endurance fans across the world.”

Gerard Neveu, WEC president

Les plans de convergence devraient être soumis au vote lors de la prochaine réunion du Conseil mondial du sport automobile de la FIA, où l’Hypercar et le LMDh seraient potentiellement ratifiés pour le calendrier 2021-2022 du WEC (World Endurance Championship).

A name for the class where Hypercars and LMDhs will vie for overall wins is expected to be revealed, along with the technical regulations for the new formula, at March’s Super Sebring event where IMSA and the WEC serve as co-headliners.

L’objectif est qu’à partir de septembre 2021 au WEC de la FIA et à partir de janvier 2022 au WeatherTech Championship, les constructeurs puissent entrer dans la catégorie supérieure et participer aux deux championnats de pointe en endurance avec ce nouveau modèle de voiture, le LMDh.

Les deux organismes de sanction se sont inspirés d’éléments de leurs réglementations respectives, à savoir de l’Hypercar du Mans de l’ACO et de celles en préparation par l’IMSA pour le DPi 2.0.

‘Convergence between IMSA and the ACO comes at the request of numerous auto manufacturers who implored the storied organizations to find a common ground with prototypes.’

[ICE! KERS! hydrogen?]

Basée sur un nouveau châssis commun à l’ACO et à l’IMSA, utilisant des éléments de l’Hypercar du Mans et du châssis LMP2, et construite par les quatre constructeurs actuels de la LMP2 : Dallara, Ligier, Multimatic et Oreca.

The formation and execution of LMDh will follow practices that have worked well in DPi since its 2017 launch. Like the existing LMP2-based DPi regulations, where four approved chassis constructors — Canada’s Multimatic, France’s Ligier and ORECA, and Italy’s Dallara — supply auto manufacturers with customized cars using stylized bodywork to carry their preferred choice of engines, the ACO and IMSA have signed contracts with the same four companies to produce LMDhs.

Ce châssis sera également utilisé pour la nouvelle génération de LMP2. La voiture utilisera un système hybride KERS commun, sur l’essieu arrière. Sa silhouette et son design seront modifiables, développés en fonction de la marque ou du style du constructeur qui fournira la puissance du moteur de la voiturePlus de détails techniques sur la voiture seront révélés en mars à SuperSebring, lors d’une présentation des départements techniques de l’ACO et de l’IMSA.

Ongoing efforts by IMSA to identify a spec kinetic energy recovery system (KERS) will be completed and made mandatory for every LMDh model. The hybrid internal combustion engine (ICE) and KERS package will drive the rear wheels, where energy harvesting will take place under braking and be fed back to the rear tires to boost acceleration. An electronic horsepower target in the 40-50hp range remains.

“On the eve of IMSA’s 51st season of competition, future race fans will regard today as one of the most significant of all time for IMSA, the ACO and the world of sports car racing,”

“Providing a common platform for top-level prototype racing globally has been a goal for the sanctioning bodies, our manufacturers — and most importantly, sports car racing fans everywhere — for many years, and we are proud to say the opportunity has finally arrived.

We are grateful for the collaboration with our partners at the ACO and the open dialogue with our manufacturer partners that led us to today’s introduction of the LMDh platform.”

John Doonan, IMSA president

À l’avenir, la catégorie supérieure des courses d’endurance comprendra à la fois la LMDh et l’Hypercar du Mans. Un système d’équilibre des performances garantira une concurrence équitable.

The acronym LMDh, which was not defined by the ACO or IMSA in Friday’s announcement at Daytona International Speedway, could come to stand for ‘Le Mans Daytona hybrid’ – or Hydrohen – once both parties agree on the final

new manufacturers on the LMDh horizon, Ford, Lexus, McLaren, and Porsche are among the major brands that could join Acura, Cadillac, and Mazda at Daytona, Le Mans and other famous endurance events in the next two years.

Peugeot, which announced a Hypercar program for 2022, is expected to shift its plans to LMDh, giving the new formula another famous manufacturer to bolster its ranks.

Team up! ACO & IMSA FORGE FUTURE OF ENDURANCE RACING

Full text. official.

The Automobile Club de l’Ouest (ACO) and North America’s sanctioning body for endurance racing, the International Motor Sports Association (IMSA), have today announced that agreement has been reached for a common future with convergence of the top categories of endurance racing.

On the occasion of the 2020 Rolex 24 At Daytona, the two sanctioning bodies unveiled the guiding principle for this platform – the introduction as the top category of competition of LMDh, which will be eligible for both the World Endurance Championship (WEC) and the IMSA WeatherTech SportsCar Championship.

This joint platform responds to the wishes of numerous manufacturers.The chance for automotive manufacturers to compete with the same car at the 24 Hours of Le Mans, the Rolex 24 At Daytona, at SuperSebring or at Spa-Francorchamps, at the Motul Petit Le Mans or even Silverstone, will soon become a reality.The ACO and IMSA have together established the basis for joint regulations to govern the new LMDh category.

The objective is that, from September 2021 in the FIA WEC and from January 2022 in the WeatherTech Championship, manufacturers will be able to enter the top category and compete in the two leading championships in endurance racing with this new model of car, LMDh.

The two sanctioning bodies were inspired by elements from each of their respective regulations, namely from the ACO’s Le Mans Hypercar and those in preparation by IMSA for the DPi 2.0.

The result of this convergence, the LMDh car will be:

  • Based on a new chassis common to both ACO and IMSA, using elements of the Le Mans Hypercar and LMP2 chassis, and built by the four current LMP2 manufacturers: Dallara, Ligier, Multimatic and Oreca. This chassis will also be used for the new generation LMP2.
  • The car will use a common hybrid KERS system, on the rear axle.
  • Its silhouette and design will be modifiable, developed according to the brand or style of the manufacturer which will provide the engine power for the carMore technical details for the car will be revealed in March at SuperSebring, in a presentation from the ACO and IMSA Technical Departments.

In the future the top category of endurance racing will include both LMDh and Le Mans Hypercar. A balance of performance system will ensure fair competition.
