BMW and Toyota have confirmed their collaboration in fuel cell technology, with BMW planning to introduce its first series-production hydrogen car in 2028. While the specific model is yet to be disclosed, it is highly speculated that it will be based on the BMW X5 platform, particularly the G65 model. This move follows BMW's years of experimentation and testing with hydrogen vehicles, including the iX5 Hydrogen test fleet. The X5's size, popularity, and existing hydrogen development make it a rational choice for this historic launch. The decision to potentially use the CLAR platform over the Neue Klasse architecture for the future hydrogen X5 remains a point of interest. BMW's partnership with Toyota, known for its Mirai hydrogen car, aims to deliver unique hydrogen vehicles under their respective brand identities. The collaboration also extends to improving the global hydrogen refueling infrastructure, crucial for the success of hydrogen-powered vehicles. BMW's strategy of integrating hydrogen technology into an existing model lineup like the X5 showcases a careful market approach, avoiding the risks associated with launching a new model. The X5's attributes make it a suitable candidate for incorporating the premium hydrogen tech, aligning well with BMW's customer base expectations. The article ends with a playful note on the potential naming conundrum for the hydrogen-powered X5, highlighting the ongoing BMW naming convention saga.
