The first details of the internal combustion element of the car’s hybrid powertrain were announced on Monday, along with the release of another teaser image of the Lamborghini LMDh being developed in conjunction with French manufacturer Ligier Automotive.
The LMDh engine will be an early base design by Lamborghini Squadra Corse’s in-house motorsport department established in 2013, unlike the production-based V10 that powers its single-brand Huracan GT3 and Super Trofeo machines.
The Italian manufacturer has revealed that the powertrain will be a 90-degree V8 but not the capacity, although it is understood to be in the region of four litres. It will weigh 180 kg, the minimum provided for by the regulations.
The combined power output of the new V8 and the hybrid system jointly developed by Bosch, Williams and Xtrac has been listed by Lamborghini at 500 kW (670 hp), the average figure in the 480-520 kW range established both in the LMDh and Le Mans Hypercar. regulations.
Lamborghini has also confirmed the dimensions of its future prototype: it will fall within the class maximums allowed for width, length and height, 2000mm, 5100mm and 3148mm respectively. The indicated weight is 1030kg, the minimum authorized in LMDh.
Further technical details on Lamborghini’s as-yet-unknown competitor are not expected until photographs of the car are released in the first quarter of 2023. This will precede the start of testing, which is scheduled for next spring.
Mirko Bortolotti and Andrea Caldarelli, longtime Lamborghini factory GT drivers, have been announced as the first drivers for the LMDh program and will spearhead the development of the car.
The team or teams that will race the new Lambo LMDh in the WEC and IMSA, where it will compete in the GTP and Hypercar categories respectively, have yet to be announced.

Lamborghini’s latest statement on the LMDh program, which was announced in mid-May, highlighted the Volkswagen brand’s desire to hybridize its road car lineup under a strategy dubbed Cor Tauri, which means heart of the bull in Latin.
He said that “stepping into a motorsport landscape driven by hybrid propulsion is perfectly suited to Lamborghini’s transition to hybrid technologies”.
Who does what in LMDh?
Porsche’s new 963 is powered by a twin-turbo V8, like the Lambo. It’s a 4.6-liter unit that has its roots in the naturally aspirated engine that powered the successful RS Spyder in the second half of the 2000s.

What’s described as an all-new 5.5-liter V8 powers Cadillac’s V.LMDh, though whether it’s turbocharged or normally aspirated hasn’t been confirmed. Spy footage of car testing at Sebring appears to confirm the latter.
Honda Performance Development has developed an all-new 2.4-liter twin-turbo V6 for the Acura ARX-06, which, like the Porsche and Cadillac, is already operational and will race next year in the IMSA series.
BMW has taken the twin-turbo route for its M Hybrid V8. The starting point for the development of its LMDh block was the final evolution of its atmospheric DTM V8 used in 2017-18, of which it retains the four-litre displacement.
Alpine has not yet confirmed the technical details of its LMDh which, like the Lambo, will enter competition in 2024. For now, it has only told us that its development partner is ORECA.
