Years of manufacture	2014 to present
Length	60 feet
Width	100 inches
Power/Fuel	Electric

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.

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. 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.
