Alexander Dennis Limited and BYD UK announced that their electric vehicle partnership, the UK’s leading electric bus producer, has taken an order from First Bus for five BYD ADL Enviro400EV electric double deck buses, which will be used on Park & Ride services in West Yorkshire. The British-built zero emission buses will operate from First’s Hunslet Park depot in Leeds, where charging infrastructure was introduced last year to support the expansion of zero-emission buses in the city fleet. First has chosen the larger model of the BYD ADL Enviro400EV at 10.8 metres long and a height of 4.3 metres. The buses will have 69 seats and will use zero-emission heat pump technology to control interior heating and cooling. The all-electric vehicles are part of an ongoing investment programme by First West Yorkshire to upgrade its fleet in the city with zero emission and ultra-low emission buses, and part of a wider commitment by First Bus to operate a fully zero-emission fleet by 2035.
