CaetanoBus, a Portuguese manufacturer, has expanded its urban bus portfolio with a focus on enhancing powertrain configurations and sustainability. In this new generation, all zero-emission buses will be equipped with LFP batteries from CATL, providing improved performance and durability compared to the previous NMC cells. The shift includes adopting a CRRC motor for battery-electric and hydrogen fuel cell electric buses, while maintaining Toyota's hydrogen components in the H2 City Gold model. CaetanoBus has received significant orders for hydrogen buses and positions itself as a pioneer in hydrogen drivetrain integration. The company is also transitioning to alternative drivetrain suppliers, such as utilizing CATL's BC5 battery system for BEV models, offering various kWh capacities for different bus sizes. The integration of CRRC's drivetrain with Toyota's fuel cell technology and CATL battery packs in the hydrogen buses highlights a comprehensive and innovative approach to sustainable transportation solutions. The company's focus on scalability and flexibility ensures the seamless integration of advanced systems across its entire product range, reflecting a commitment to cutting-edge e-mobility engineering. With collaborations with Toyota and Mitsui & Co., CaetanoBus is at the forefront of urban and airport buses innovation, with plans to introduce a hydrogen-powered coach in partnership with Temsa in the near future.
