Toyota has been very active lately, revealing a number of interesting concept cars previewing future models and technologies (see the related links below). That activeness comes to its culmination with the GR H2 Racing Concept unveiled today at the Circuit de la Sarthe in western France ahead of this weekend’s 2023 24 Hours of Le Mans. The hydrogen-powered endurance race car concept was revealed by Akio Toyoda, Toyota’s chairman.

The automaker doesn’t release technical specifications for the hydrogen engine prototype, only saying it is 5,100 mm long and 2,050 mm wide. This makes it slightly longer and wider than Toyota’s LMP1-H Le Mans Prototype, which is 4,650 mm long and 1,900 mm wide. The Japanese firm also confirms powering the race car concept is a mix between a hydrogen engine and a hybrid system, but this is literally everything we know about what’s happening under the skin.
