LMH (Le Mans Hypercar)

LMH, Le Mans Hypercar, is one of the two technical platforms allowed in the Hypercar class. An LMH constructor designs the entire car: chassis, bodywork and powertrain, with the option of a front-axle hybrid system. Toyota's GR010 and Ferrari's 499P are LMH designs.

The freedom costs more than the alternative LMDh route, which mandates a spec chassis and hybrid package. The two platforms race together under a Balance of Performance that aligns their power, weight and aerodynamic performance, so the choice between them is a question of budget and brand philosophy rather than lap time.
