Major automotive manufacturers will work together with one of four approved chassis constructors – Dallara, Ligier, Multimatic or ORECA – to develop their LMDh race cars. Between the manufacturer’s internal combustion engine and a spec hybrid powertrain system, each LMDh car will have a combined power output of 500 kilowatts (just over 670 horsepower).
Minimum weight will be 1,030 kilograms (just over 2,270 pounds), with a maximum width of two meters (roughly six-and-a-half feet), a maximum length of 5.1 meters (16.7 feet) and a common wheelbase for all cars of 3.15 meters (10.3 feet). Each LMDh car will have advance upper body styling, allowing each automotive manufacturer to bring their own identity and styling cues, while each LMDh will have a controlled underfloor.
