Alexander Dennis Limited and BYD UK jointly announced that ADL and BYD will commence the design and assembly of chassis for the BYD ADL partnership's electric single and double deck buses for the British market, ensuring completed vehicles are built in the UK. ADL is a subsidiary of leading independent global bus manufacturer NFI Group Inc. ("NFI"), while BYD is a global leader in batteries, energy management and electric mobility. Electric bus chassis assembly will take place in ADL's facilities with on-the-ground support from the BYD team, and is planned to commence in the second half of 2021. This significant step has been taken in response to the increasing demand for zero emission vehicles. It further strengthens the partnership's market-leading position while underpinning jobs in Britain and developing skills in the growing market for clean vehicle technology. Until now, chassis for the BYD ADL Enviro200EV single deck and BYD ADL Enviro400EV double deck buses were fully built by BYD before being delivered to ADL's facilities in the UK to have their bodywork fitted.
