Hybrid is the best lah. No need to headache. The microcontroller
will decide how & which engine to run. Hot day can still
achieve 20~km/l, where to find.
Hybrid is the way to go besides CNG as far as i am concerned .
Sadly government do not encourage greener vehicles due to
national intere$t .
Sadly all taxi companies take revenue ahead of environmental
issues .
Hybrid will be ideal if oil prices are low .
Hybrid will be ideal if no 5-years-contract ,
Hybrid will be ideal , if TransCab replace their aging Crown
.
