The Phoenix Public Transit Department in Arizona has successfully tested and deployed its first group of hybrid buses on the city's roads. This initiative is part of the department's commitment to achieving a zero-emissions bus fleet by 2040. The hybrid buses utilize a combination of a hybrid-electric motor, batteries, and a biodiesel-fueled engine, resulting in improved fuel economy, reduced emissions, and quieter operation. Phoenix Mayor Kate Gallego expressed pride in leading the city towards a greener future, emphasizing the benefits of cleaner air for residents. The New Flyer Xcelsior hybrid-electric bus can accommodate up to 35 passengers, with additional standing capacity, including three wheelchair areas and a driving range exceeding 500 miles. The Phoenix Public Transit Director, Jesús Sapien, highlighted the agency's commitment to providing reliable and environmentally friendly transit services. Currently, the transit department operates a sizable fleet of heavy-duty buses running on alternative fuels like natural gas and biodiesel. With a recent grant from the Federal Transit Administration, Phoenix Public Transit plans to further enhance its fleet by replacing older buses with battery electric and hydrogen fuel-cell buses, along with infrastructure upgrades and workforce development initiatives.
