In order to promote the development of green transportation in Macau, Transmac has specially introduced an extended-range electric bus with a solar power generation system. The roof is equipped with 8 solar panels and when the light conditions are good, the energy generated by the solar panels can be used for the vehicle. The bus is also equipped with an ECAS side kneeling system to facilitate passengers getting on and off the bus, and it is also equipped with an anti-slip control system to reduce accidents caused while the bus is on a ramp.
