The BYD Auto K11M, also called the "Lancaster", is a low floor, articulated battery-electric transit bus. The bus was launched at the 2014 American Public Transportation Association Expo in Houston, Texas. The first customer to take delivery of the 60-foot electric bus was the Antelope Valley Transit Authority in May 2017. The 13 buses are part of their campaign to fully electrify its fleet by 2018.[1]

Initially, the K11M promised a range of 170 to 200 miles or 273 to 321 kilometres in an urban environment. It could be fully charged in two to three hours.[2][3] By 2019, a high capacity battery option was available and increased the range to 220 miles or 354 kilometres. Though by 2021, specifications advertised a revised working range of 193 miles or 311 kilometres.

Like the 12-metre BYD Auto K9, the K11M uses in-wheel traction motors (on the 'C' axle) and iron-phosphate batteries. The outward appearance was quite different from the K9 at the front and rear ends along with a more rounded roofline. On production buses, the appearance of the K11M is in line with BYD’s K9MC and K9S.
