Toyota has revealed a hydrogen-powered prototype of the Hilux pickup truck, with 10 units produced at the Derby factory in the UK. This model is set to make its global debut at the 2024 Olympic Games opening ceremony in Paris. The prototype, based on the extra-cab version of the Hilux, features a hydrogen engine that allows a driving range of up to 600 km on a single tank. The design changes in the driver's environment include a hydrogen tank gauge and a drive mode selector similar to Toyota's Mirai model. The engine, which generates electricity from hydrogen and oxygen, emits only clean water vapor. The hydrogen engine in the Hilux prototype is fed by three tanks with a capacity of 2.6 kg each, placed under the front hood between the ladder frame rails. An electric motor in the rear axle delivers 182 hp directly to the wheels, with a battery storing the electricity produced. Despite the advantages of hydrogen engines like faster refueling and lighter weight, the main challenge lies in establishing a widespread refueling infrastructure. Toyota emphasizes the need for regulatory support to boost the adoption of hydrogen technology for mass production. The success of hydrogen-powered vehicles in the future will depend on the development of necessary infrastructure and regulatory interventions.
