Both Toyota and Hino have declared ambitious goals to reduce CO2 emissions by 2050 and are continuing to develop electrified vehicle technologies for widespread use. In order to achieve broader reductions in CO2 emissions, major improvements will be required in the environmental performance of heavy-duty trucks, which account for about 60 per cent of the total CO2 emissions from commercial vehicles operating in Toyota and Hino’s home market of Japan.
For the electrification of commercial vehicles, the optimum powertrain must be adopted to ensure both environmental performance and practicality as a business vehicle, in terms of cruising range, load capacity and other commercially relevant aspects of operation. Heavy-duty trucks are typically used for inter-city transportation. Therefore, they are required to have sufficient cruising range and load capacity as well as fast refuelling capability. For this reason, fuel cell vehicles that run on hydrogen, with its high energy density, are considered effective.
The heavy-duty fuel cell truck being developed is based on Hino Profia and will take maximum advantage of the vehicle technologies delivered by Toyota and Hino 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, equipped with two Toyota fuel cell stacks newly developed for Toyota’s next generation Mirai, includes elements of vehicle driving control applied through heavy-duty hybrid vehicle technologies developed by Hino.
Cruising range will be set at approximately 370 miles, aiming to meet high standards in both environmental performance and practicality as a commercial vehicle.
Toyota and Hino have positioned hydrogen as an important energy source for the future and have worked together on the development and proliferation of fuel cell technologies since conducting joint trials of a fuel cell bus in 2003. Going forward, Toyota and Hino will further strengthen this partnership and accelerate efforts toward the realisation of a hydrogen society.
