The BYD ADL partnership, has unveiled the first of 37 new, zero-emission, fully electric BYD ADL Enviro400EV double deckers for delivery to London bus operator, Metroline.

The first five vehicles entered service on Metroline’s route 43 as part of the bus operator’s contract with Transport for London (TfL), operating out of Metroline’s Holloway Bus Garage.

The new Enviro400EV possesses the same "DNA" as its proven Enviro200EV stablemate with a new chassis and lightweight aluminum double-deck body work.

Power is delivered via BYD’s fully electric drivetrain technology providing an impressive 160-mile range. The drivetrain features BYD’s innovative wheel-hub-motor — meaning no gearbox, driveshaft. or differential componentry.

The new double-deck layout specifically for the Metroline order boasts a capacity of 67 seats in total. A modern exterior retains the traditional design cues of London’s iconic red double-decker. The bus features a glazed staircase meant to be aesthetically pleasing for passengers, while also being ADA compliant.

The new BYD ADL Enviro400EV is built in Britain at ADL’s facility in Scarborough, Yorkshire, using BYD components assembled into a powered chassis built in Europe at BYD’s plant in Komarom, Hungary.
