BYD BD11 double decker buses enter service on London Superloop routes with 532 kWh battery

Since mid 2025, BYD BD11 electric double decker buses have been deployed on Transport for London's Superloop network, including route SL4 from Grove Park to Canary Wharf. The BD11 features a 532 kWh battery spanning the lower deck floor, 90 passenger capacity, and safety systems including Advanced Emergency Braking and Blind Spot Monitoring. BYD has supplied hundreds of double decker buses to London, though the article notes some public concerns about TfL's reliance on the Chinese manufacturer.

Why it matters: The deployment demonstrates BYD's growing footprint in the UK public transport market and highlights the charging infrastructure requirements for high capacity, long range electric buses on extended urban routes. The 532 kWh battery specification sets a benchmark for depot charging capacity planning as operators electrify double decker fleets.
