Porsche’s last Le Mans victory, earned in 2017 with the 1000-hp LMP1 919 Hybrid, served as the German brand’s farewell from prototype action. Among the fastest sports cars ever made, Porsche struggled to reconcile the 919’s jaw-dropping performance with the nine-figure budgets it devoured while playing on the world stage.
In selecting IMSA’s LMDh as its preferred formula, Porsche eschewed its other option, the WEC’s costlier Le Mans Hypercar regulations. With LMDh, car companies partner with one of four spec LMP2 prototype suppliers, supply its desired internal combustion engine, affix a spec 40hp kinetic energy recovery system to comply with the hybridization rules, and design custom bodywork that features styling elements from its road cars. For LMH, purebred prototypes are allowed, along with race-converted supercars, and all manner of engine options and high-power KERS systems are permitted.
Exceptional creativity lives within LMH, and it’s here where projected budgets diverge with LMDh.
