LMH has been introduced as a replacement for the LMP1 category, in a bid to reduce costs at the top end of endurance racing and increase its appeal to automotive manufacturers, after the likes of Audi and Porsche withdrew to leave Toyota as the only OEM remaining.
Toyota introduced its GR010 HYBRID for the start of the 2021 WEC season, while the US-based boutique manufacturer Glickenhaus added its non-hybrid 007 LMH to the field in time for the second round in Portimao.
