Today, BYD launched what it says is the world’s longest electric bus, the K12A. At 88 feet long, the red bi-articulate bus looks like a giant caterpillar. It can carry up to 250 people, reach a max speed of about 40 MPH and travel 186 miles on a single charge. The bus is headed for the country of Colombia, where it will be part of the TransMilenio bus rapid transit system (BRT), but it could join other BRTs.
