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.
