Hydrogen cars offer several advantages over EVs, such as faster refuelling times, typically comparable to refuelling a conventional gasoline vehicle, and longer driving ranges due to the higher energy density of hydrogen. Additionally, hydrogen fuel cell vehicles provide a similar driving experience to traditional internal combustion engines, making them more familiar to consumers. However, hydrogen cars face challenges including the limited availability of hydrogen fueling infrastructure, higher production and storage costs, and the need for energy-intensive hydrogen production. As the automotive industry strives to reduce emissions, Toyota has unveiled its latest innovation on the eve of the 2023 24 Hours of Le Mans. The Toyota GR H2 Racing concept, a hydrogen-fueled Le Mans prototype race car, hints at the possibilities of a hydrogen-powered future on the racetrack. Let’s explore this concept and its potential impact on the racing world.
Toyota is collaborating with Yamaha to design a V8 Hydrogen Engine
Since 2021, Toyota has been competing in Japan’s Super Taikyu Series with a Corolla-based race car featuring a hydrogen engine. Although burning hydrogen produces zero CO2 emissions, addressing nitrogen oxide emissions remains a challenge. Toyota plans to tackle this issue by employing urea-based selective catalytic reduction technology, similar to what is used in modern diesel engines. Furthermore, the limited availability of hydrogen fueling stations poses a huge hurdle, but it seems like the industry is actively working to expand the infrastructure.
While specifics about the engine used in the GR H2 Racing concept were not disclosed, Toyota has been collaborating with Yamaha to develop a V-8 hydrogen engine. Yamaha’s expertise, previously demonstrated in the Lexus LFA supercar‘s V-10 engine, adds further credibility to this bold endeavour.
Toyota emphasizes that the GR H2 Racing concept extends beyond mere styling exercise. The World Endurance Championship, renowned for the iconic Le Mans race, plans to introduce a hydrogen-powered class in 2026. By implementing Balance of Performance rules, the championship aims to ensure fair competition among hydrogen-powered and fuel-cell cars.
