The Zhongtong Sunny is a series of city and intercity buses produced by Zhongtong for 8.3 to 12.0 metres length. Available versions since launch include LCK6103G, LCK6112G, LCK6121GHEV, LCK6125G, LCK6125G-1, LCK6830G, LCK6841GC and LCK6910G.
The LCK6121GHEV is essentially the hybrid electric variant, with a length of 12.0 meters.
SMRT used to operate one demonstrator unit of the Zhongtong Sunny LCK6121GHEV.
In 2011, SMRT received a Zhongtong Sunny LCK6121GHEV demonstrator for a 6 month evaluation. It was the first hybrid electric bus to be operated by SMRT.
At the end of a trial, the bus was returned to the dealer and no further purchases were made. It was sold to Travel GSH in 2013.
