Toyota and Hino have agreed to jointly develop a heavy-duty fuel cell truck, and to proceed with initiatives toward its practical use through verification tests and other means. Toyota and Hino have declared ambitious goals to reduce CO2 emissions by 2050 and are developing electric vehicle technologies for widespread use in society. In order to achieve further reductions in CO2 emissions, major improvements will be required in the environmental performance of heavy-duty trucks, which account for about 60 percent of the total CO2 emissions from commercial vehicles in Japan. For the electrification of commercial vehicles, the optimum powertrain must be adopted to ensure both outstanding environmental performance and just-right practicality as a business vehicle in terms of cruising range, load capacity, and other aspects depending on the usage.
Heavy-duty trucks are typically used for highway transportation; therefore, they are required to have sufficient cruising range and load capacity as well as fast refueling capability. For this reason, fuel cell vehicles that run on hydrogen with its higher energy density are considered effective. The heavy-duty fuel cell truck in this joint development project is based on Hino Profia, and is being developed taking maximum advantage of the technologies both Toyota and Hino have cultivated over the years. The chassis is specially designed with the optimum packaging for a fuel cell vehicle, and steps are being taken through comprehensive weight reduction to ensure a sufficient load capacity.
The powertrain is equipped with two Toyota fuel cell stacks that have been newly developed for Toyota’s next Mirai and includes vehicle driving control that applies heavy-duty hybrid vehicle technologies, developed by Hino. Cruising range will be set at approximately 600 km, aiming to meet high standards in both environmental performance and practicality as a commercial vehicle.
