With its more compact wheelbase, the 10.3m long model will increase manoeuvrability when navigating congested roads and tight corners.
The partnership launched the double deck BYD ADL Enviro400EV in 2019, enabling the electrification of busy bus services. Over 450 of the standard 10.8m version have since been sold to operators in London and other UK cities.
Operators will now have the option of a new version that is just 10.3m long. This new length is achieved with a wheelbase that has been shortened by 50cm to 5.4m, which benefits manoeuvrability in challenging inner-city routes such as in those found in London.
BYD's dedicated R&D team in the UK has been responsible for the rapid development of the new 10.3m chassis. It worked in close collaboration with ADL's body engineers, who ensured that the battery placement gives optimum weight distribution, while ample power remains available to deliver a full day's operation.
A demonstrator will be available from the second half of 2021 for operators to trial on their routes.
Paul Davies, ADL president & managing director, said: "As bus companies across the United Kingdom make the switch to electric buses with support from national and local government, the BYD ADL partnership is preparing to ‘Build it in Britain' with complete assembly of electric buses in our facilities here in the country.”
