Home / SMRT Buses, Singapore (before GCM/BCM) / Zhongtong LCK6121GHEV Hybrid 11

SMRT Buses conducted a six-month hybrid bus trial with a Zhongtong LCK6121GHEV demonstrator between January 2011 and July 2011, registered SMB137A. Similar to the other trial SBS Transit was conducting, it uses the Eaton automatic transmission system.

While the parallel hybrid bus uses its batteries to power the electric motors for most of the time, the Cummins ISBe4 225B Euro IV diesel engine (6,693cc) provided any additional power if necessary. EDS was supplied by Mobitec and air-conditioning was from Tongsun.

SMRT Buses returned the bus after the trial was completed, and no further purchases were made. This bus was subsequently sold to private operator Travel GSH and used in Peak Period Short Services (PPSS).
