Toyota and BMW have announced a collaboration to work on a next-generation hydrogen fuel-cell powertrain that will be used in their production models. Both companies have a history of exploring hydrogen fuel-cell technology, with BMW having previously developed a demo fleet of the iX5 Hydrogen FCEV models. Although Toyota's Mirai sedan has faced challenges due to a narrow hydrogen network in the US, the automakers remain dedicated to advancing fuel-cell technology. They plan to introduce series-production fuel-cell electric vehicles in 2028, maintaining the unique brand identities of BMW and Toyota. While BMW has experimented with hydrogen technology in SUVs and sedans, Toyota has been offering the Mirai sedan in a limited region. The collaboration aims to provide customers with diverse FCEV options. Other automakers like Hyundai and Honda are also investing in hydrogen technology. Despite the increasing popularity of battery-electric models, the partnership between Toyota and BMW signifies a continued commitment to sustainable mobility solutions and innovation in the automotive industry.
