Lamborghini has announced the SC63 as its LMDh Hypercar entry


Le Mans 2023 represented a new dawn of endurance racing – the Hypercar era had begun proper, with Ferrari, Toyota, Porsche, Peugeot and Cadillac fighting it out for top honours.

Now, anticipation for the 2024 race is already building, with Lamborghini the latest marque to unveil its challenger for the world’s biggest race.

The SC63 was revealed at Goodwood Festival of Speed, and in addition to running at La Sarthe will also taken on the full WEC season as well as an IMSA campaign, which will take in the Daytona 24 Hours and Sebring 12 Hours.

The Italian marque will join Porsche, BMW, Acura, Cadillac and Alpine as LMDh contenders.

These cars will run under a ‘Hypercar’ umbrella class, alongside cars run to the Hypercar regulations also – which includes Toyota, Peugeot, Ferrari and Glickenhaus.

The influx of entrants is evidence that the new LMDh regulations, which came into play in 2022, are working as intended.

Designed to cut the costs of racing, these new rules stipulate that a chassis that must be bought from one of four suppliers and a that a standard hybrid system must be used. The cars will be eligible for both the World Endurance Championship (WEC) and North American IMSA Sportscar Championship, enabling them to fight for overall wins at Le Mans and Daytona.

In 2023, we’re now seeing Ferrari, Toyota, Peugeot, Porsche and Cadillac competing for the overall Le Mans win — with customer teams and other manufacturers in the mix too.

LMDh entries: confirmed manufacturers and teams, plus rumours


LMDh vs Hypercar

LMDh cars will compete against Le Mans Hypercars in WEC, including the Le Mans 24 Hours.

The Hypercars — being built by Peugeot and Toyota among others — offer manufacturers greater freedom but at a higher development cost.

The ACO, which organises WEC, and drew up the LMDh regulations with IMSA, is attempting to ensure close racing by harmonising the regulations: the power limit, minimum weight and aerodynamic performance of both types of car will be identical.

However, only the Hypercars will have four-wheel drive, with the combustion engine driving the rear axle and an electric motor at the front. In an attempt to reduce the advantage, the Hypercars won’t be able to engage the electric drive below 75mph in normal racing conditions.

A Balance of Performance system will also be used.


Balance of Performance

A new Balance of Performance process is used Le Mans Hypercars and will extend to LMDh when the first cars appear in 2022, as part of attempts to ensure close racing.

After the 2023 Six Hours of Spa, the race prior to Le Mans and often seen as indicative of performance, the FIA and ACO made further BoP changes for the blue riband race in the form of extra ballast relative to their pace in Belgium.

Toyota was given 37kg, Ferrari 24kg, Cadillac 11kg and Porsche 3kg.

As Gary Watkins explained, the first two teams were less than happy with the changes.

“In light of what happened this week, no one is going to show their hand on Sunday when the Le Mans field takes to the hallowed asphalt of the Circuit de la Sarthe,” he says. “Like it or not, it looks like sand-bagging is back.”

Parameters for BoP include adjusting weight, fuel flow and energy deployment from the hybrid system.


What does LMDh stand for?

‘LM’ stands for Le Mans whilst the ‘D’ stands for Daytona to reflect the regulations, which are designed to unify elite sports car racing. What does ‘h’ stand for? No-one’s quite sure. WEC prefers ‘hypercar’ whilst IMSA has moved towards ‘hybrid’.


LMDh technical regulations explained


The LMDh car is based on an enhanced iteration of LMP2’s next-generation chassis. Entrants can choose from four options made by one of the specified manufacturers: Dallara, Oreca, Ligier and Multimatic.

  • Manufacturers have relatively free-rein over the styling of the bodywork, enabling them to incorporate aspects from road cars.
  • Underfloor aerodynamics are tightly controlled. Each car will have a limited downforce to drag ratio of 4:1.
  • Maximum dimensions are 5100mm in length, 2000mm wide and 3150mm wheelbase.
    The car’s minimum weight is 1030kg.



To cut costs, LMDh cars must be fitted with a specified hybrid system and power management software. It’s a major divergence from Le Mans Hypercars, which are allowed to run entirely bespoke powertrain systems.

In both categories, manufacturers can design their own combustion engines with few major restrictions except for a cap on power output.

  • The combined LMDh powertrain is limited to produce a maximum of 500kW (671bhp) at any one time. The engine, designed by manufacturer entrants – must provide a minimum peak output of 470kW (630hp).
  • The spec hybrid system produces 50kW (67bhp). Bosch is developing the hybrid motor, Williams Advanced Engineering the battery and Xtrac the gearbox.
  • The system is supposed to withstand 22,000km (14,000 miles) of running, equivalent to more than four Le Mans 24 Hours races, between rebuilds and has its software locked so teams cannot tinker.



In terms of lap times, the cars are expected to clock in around 3min 30sec at La Sarthe. The lap record set by Toyota’s Kamui Kobayshi in qualifying last year is 3min 14.791.

Whilst markedly slower than current LMP1 cars, the ACO, FIA and WEC will be hoping an increased field size will make the trade-off worthwhile. This has been boosted by both Porsche and Audi saying they hope to supply customer LMDh cars in addition to their works efforts.



What makes LMDh so potentially attractive to manufacturers and entrants is the cost. The hybrid system will cost €300,00, the chassis €345,000, with the total (once the bodywork is added in) coming to around €1m before the combustion engine is factored in.

To compare, Porsche’s 919 LMP1 programme, which was run between 2014-2017 and only eligible to race in WEC, is said to have cost $200m.

As Porsche’s CEO Oliver Blume put it: “The new LMDh category allows us to fight for overall victories with a hybrid system at the Le Mans, Daytona and Sebring classics – without breaking the bank.”


LMDh entries: which teams and manufacturers are confirmed? Who’s next?

Lamborghini – confirmed for 2024

Lamborghini will now vye for sports car racing’s greatest prize


Lamborghini has taken the wraps off its LMDh Hypercar, the SC63, intending to enter both WEC and IMSA for 2024, which includes Le Mans, Daytona and Sebring.

This will be the first time Lamborghini has vied for top honours at any of the endurance classics.

“The SC63 is the most advanced racing car ever produced by Lamborghini and it follows our roadmap ‘Direzione Cor Tauri’ laid out by the brand for the electrification of our product range,” said Stephan Winkelmann, Lamborghini Chairman and CEO.

“The opportunity to compete in some of the biggest endurance races in the world with a hybrid prototype fits with our vision for the future of high-performance mobility, as demonstrated for road legal cars with the launch of the Revuelto. The SC63 LMDh is the step into the highest echelons and into the future of motorsports for our Squadra Corse.”

With a chassis provided by Ligier, the SC63 will be powered by a 3.8-litre twin turbo V8 engine, married to the spec hybrid system.

The Italian firm’s campaign will be run by successful GT squad Iron Lynx, with a number of drivers already announced.

Mirko Bortolotti and Andrea Caldarelli have been confirmed, as well as former F1 men Romain Grosjean and Daniil Kvyat, the former two already involved in GT competition with Lamborghini.

Bortolotti is a two-time Rolex 24 at Daytona GTD-class winner with Grasser Racing Team, while Caldarelli was part of Paul Miller Racing’s GTD win in 2020 at Daytona.


Lamborghini will be the second Volkswagen Group company represented in WEC’s top tier, with Porsche confirmed but with Audi pausing its project.


Porsche – confirmed


Porsche has tested at Daytona and other locations


Three years after closing its LMP1 919 programme, Le Mans’ most successful manufacturer (with 19 overall wins) is back again at endurance’s top table for 2023 – this time in partnership with legendary American outfit Team Penske, which is running Porsche’s newly-christened 963 LMDh prototype.

The livery of the new machine has now been revealed also, a retro combination of the Obermaier Racing’s 956 No47 entered at the 1984 Le Mans, and the Salzburg Racing 917 which took the marque’s first-ever Le Mans win in 1970.

For a luxury sports car brand known for its engineering excellence, opting for a set of regs which is cheaper and has less creative input from the designers doesn’t seem to be particularly ‘Porsche’, but the company appears convinced by the longevity a cost-effective set of rules offers.

Porsche partners with Multimatic to make its respective chassis.

The Canadian company has been a technical partner with Porsche for a number of years, producing the shock absorbers for the new 911 GT3 cup car, as well as supplying suspension parts for the 919 EVO, which went on a ‘farewell tour’ of Europe after the Stuttgart marque last withdrew from WEC, setting fastest laps in 2019 at the Nürburgring and Spa-Francorchamps. Additionally, Multimatic also supplies suspension components for the 99X Formula E car and Porsche 911 RSR, which is used in both WEC and IMSA.

Penske have long been masters at getting the best out of ‘spec’ machinery, having won a multitude of championship titles and race wins in IndyCar, NASCAR and IMSA.

Porsche has now confirmed its drivers for the LMDh programme: 2018 and 2021 IMSA DPi champion and former Sauber F1 driver Felipe Nasr has been signed up for one of the berths, with Dane Cameron – 2016 and 2019 title-winner in the same class – joining him.

André Lotterer, one of Porsche’s Formula E drivers, has also been confirmed. The most experienced and high-profile of all the drivers, the German has won Le Mans three times for Audi in ‘11, ‘12 and ‘14.

Porsche has looked to its GT team for the rest of the line-up: Matt Campbell and Mathieu Jaminet step up, along with Kevin Estre, Michael Christensen, Laurens Vanthoor.

The ACO dreams of the large fields of the ’80s and ’90s, when 956s widely populated packed grids. Stuttgart is on board with this idea, having now announced two customer LMDh car programmes so far for 2023, one in WEC and the other IMSA.

This year’s Le Mans LMP2 champions JOTA will field a car in the former, with title-sponsorship from Hertz – with Antonio Felix Da Costa, William Stevens and Yifei Ye driving –
while JDC-Miller will operate an entry in IMSA.


Alpine – confirmed

2 ALPINE LMDh car Le Mans 2023

Alpine has now unveiled its ß (Beta) LMDh Hypercar


Alpine has finally made the long-expected announcement that it will build its own LMDh machine, entering the Hypercar class with two cars in WEC from 2024.

The French challenger will be based on an Oreca chassis, with an engine developed in-house at Alpine, with a prototype The cars will be run by the Signatech team, which has taken LMP2 class honours at Le Mans in ’16,’18 and ’19 – it unveiled a prototype labelled “ß” (Beta) at the 2023 Le Mans 24 Hours.

Alpine currently runs in the LMP2, stepping up with its LMDh programme for 2023.

The current Alpine line-up includes André Negrão, four-time Le Mans LMP2 class winner Nicolas Lapierre – whose CV also boasts two wins at the 12 Hours of Sebring – and Le Mans LMP2 podium finisher Matthieu Vaxiviere in the N035

The N036 features Matthieu Vaxiviere, Charles Milesi and Julien Canal.

Alpine has heavily implied it intends to supply customer teams with its LMDh car also.


Acura/Honda – confirmed

Acura Profile

Acura won out on debut at Daytona

Honda confirmed its Acura-branded LMDh entry into IMSA, where it currently races the ARX-05, with a single-sentence press release, but has since revealed fire-up footage and renders of its ARX-06 prototype, keeping its familiar nose design from the DPi era.

“The process we used in creating the exterior design for the Acura ARX-06 is exactly the same as how we create a new Acura passenger vehicle,” commented Acura Executive Creative Director Dave Marek.

“The same world-class stylists that lead Acura production car design created initial sketches, then pared those down to several potential designs. Next we created a scale model, did aero and wind tunnel model testing, and brought HPD and our partner teams in for their feedback.”

In the hands of Meyer Shank Racing, the car won out on its debut at the 2023 Daytona 24 Hours, beating the likes of Porsche Cadillac and BMW.


BMW – confirmed

An Instagram post by BMW M CEO Markus Flasch indicated the Munich marque was on its way back to Daytona and IMSA, which was followed by official confirmation, with the German marque then revealing the car in testing.

Its IMSA driver line-up has now been announced too, with Nick Yelloly, Augusto Farfus, Phillip Eng and Connor de Phillippi all set to get behind the wheel. IndyCar star Colton Herta will also join the line-up for the Daytona 24 Hours.

“My team’s job was to make the BMW M Hybrid V8 look like a BMW, and embrace every opportunity to make it also perform like one on the race track,” BMW Designworks Global Automotive Director Michael Scully said.

“The design is rooted in BMW’s DNA of purposeful, efficient performance, and the exterior’s bold, determined character invokes BMW’s frontiersmanship of turbo power, now united with an optimized hybrid electric powertrain.

“The camouflage livery celebrates the 50 Years of M by commemorating the great cars of BMW’s storied history in IMSA racing while uniquely cloaking the BMW M Hybrid V8’s future-facing exterior geometry and technologies during the critical on-track development phase of the project.”

Rahal Letterman Lanigan Racing operates the IMSA team. The outfit, run by 1986 Indianapolis 500 winner Bobby Rahal, already campaigns BMW GT cars in IMSA, in addition to running its own IndyCar team.

On top of its IMSA project, BMW will also compete in WEC from 2024 with WRT, which will mark 25 years since it won Le Mans with its last prototype appearance.

“All of us at Team WRT are extremely happy with the start of this new partnership with BMW M Motorsport and feel honoured to be associated with a brand that has such an awesome pedigree in motor racing,” said WRT’s co-owner and team principal, Vincent Vosse.

“Team WRT was launched thirteen years ago and has enjoyed continuous success in different categories, mainly GT3 and endurance racing.

“Since the very beginning, the 24 Hours of Le Mans has been in our plans and in our dreams and being part of the new Hypercar era of the FIA WEC that is about to open, was our strongest desire.

“To prepare for that, we have launched a program in LMP2 two years ago, where we have proved to be competitive and successful, taking ELMS and FIA WEC titles, and also a class win at the 24 Hours of Le Mans in our maiden participation.

“Entering the LMDh arena with a strong partner such as BMW M Motorsport was the logical next step and we are not only thrilled about the challenge ahead but also thankful for BMW M Motorsport’s trust in us.

“I can still remember when BMW M Motorsport won at Le Mans in 1999, as I was one of the drivers of the team in the neighbouring box. We will work hard to repeat these moments and live them together.”

Cadillac has now hit Le Mans, WEC and IMSA, after a twenty year-plus absence in the top class at La Sarthe.

The Cadillac Project GTP Hypercar uses a Dallara chassis, the American/Italian combination creating the DPi-V.R which won the Daytona 24 Hours four times consecutively between 2017 and 2020.

An all-new V8 5.5-litre engine, along with the spec hybrid system, powers the car.

Chip Ganassi Racing and Action Express Racing run the cars, debuting at Daytona 2023.

The American team is made up of four-time Champ Car champion Sebastian Bourdais, two-time Le Mans winner Earl Bamber, former Formula E driver and Le Mans GTEPRO winner Alex Lynn and two-time Daytona winner Renger van der Zande will compete for the team in IMSA next year, with all likely to compete at some point in LMDh for the brand.

Scott Dixon and Richard Westbrook fill out the team for Le Mans.


Lamborghini – confirmed

Lamborghini has announced 2024 LMDH entry

Lamborghini has now confirmed it will run an LMDh programme from 2024, intending to enter both WEC and IMSA.

This will be the first time a Lamborghini has vied for top honours at any of the endurance classics.

“This step up into the highest echelon of sports car racing marks an important milestone for our company,” commented Stephan Winkelmann, Lamborghini chairman and CEO. “We will be measuring ourselves against the very best, on the most demanding proving grounds.

“On one hand, this will give our successful motorsports program even more visibility, but it will also allow us to test future technologies: our LMDh prototypes will become our most sophisticated open laboratory on four wheels.”

Without officially confirming it, the Italian firm has implied it will make use of customer teams, as it does in its GT3 exploits, instead of running a works outfit.

“LMDh will play a special role in Lamborghini’s motor sports strategy, giving us the unique opportunity to expand our customer racing activities to new platforms and enforce our long-term partnership with customer teams and drivers,” the company’s head of motor sport, Giorgio Sanna, said.

It has also announced Mirko Bortolotti and Andrea Caldarelli as well asformer F1 men Romain Grosjean and Daniil Kvyat, the former two already involved in GT competition with Lamborghini.

Bortolotti is a two-time Rolex 24 at Daytona GTD-class winner with Grasser Racing Team, while Caldarelli was part of Paul Miller Racing’s GTD win in 2020 at Daytona.

“We are especially proud to announce Mirko and Andrea as the first drivers for the LMDh programme,” said Sanna.

“Both have contributed substantially to achieving historic results for Lamborghini in GT racing and their addition to the LMDh project also rewards their continued commitment to the Squadra Corse [Lamborghini’s racing division] family.

“I’m sure that their talent and experience will be an added asset to our competitiveness in the premier endurance class.”

Lamborghini will be the second Volkswagen Group company represented in WEC’s top tier, with Porsche confirmed but with Audi pausing its project.


McLaren – rumoured

McLaren F1 GTR 1995

McLaren F1 GTR took a shock win in 1995


McLaren shocked the motorsport world by taking overall 1995 Le Mans victory with their F1 GTR – run in the LM GT1 category and technically the third fastest class that year.

Could McLaren return to the endurance fold at the highest level?

The current F1 and IndyCar team has said that it’s “very happy” with the latest LMDh regs, with boss Zak Brown declaring “We’re very interested in sportscars. I think it’s a great fit for the McLaren brand and we like it a lot.”

The brand wants assurances of parity with LMH though. “One car can be four-wheel-drive and another [LMDh] is not, so it’s one thing to balance two cars in the dry with new tires.” Brown notes, “But how do you balance them at 2am in the wet at Le Mans?”


Hyundai – rumoured

2020 Monza Rally Ott Tanak Hyundai

Hyundai could soon be trading mud for the Mulsanne


Hyundai is hardly the first name that comes to mind when one thinks of sports car glory.

However, the Korean marque has become frustrated with the FIA’s determination to implement hybrid regulations in the new generation Rally1 cars next year.

Unwilling to be rushed in the development of its hybrid technology, a 2023 move to sportscars with either a Hypercar or LMDh challenger could be on the cards instead, with its Motorsport director Andrea Adamo saying “Any sort of motorsport that can show the capability, the technology and the things Hyundai can do in the world are welcome.”


Ford – has chosen GT over LMDh

Ford Le Mans 2019

Ford pulled out of Le Mans competition in 2019 but has hinted at a Hypercar or LMDh future


Ford has previously expressed interest in building a Hypercar, before the LMDh regulations then offered a more cost-effective entry.

The Detroit-based brand was involved in the development of the Hypercar rules, where it pushed for a convergence of rules across WEC and IMSA. It has finally got its wish, but then decided instead to go down the GT route, committing its new Mustang to the GT3 rules for IMSA’s GTD Pro class in 2024, instead of an LMDh programme.

“For us, having something that is more relevant or tied to a production car is what put our decision in favour of Mustang and GT3,” said head of Ford Performance Mark Rushbrook.

“It’s [LMDh] not the right programme for us at this time.”
