In New York City the Metropolitan Transit Authority has
started testing a new hybrid bus
, but this one is different from existing models. Rather than using a conventional
engine and parallel
setup, this one is a series hybrid. The bus is driven by batteries which are recharged from regenerative braking and a diesel fueled turbine engine. The MTA is testing the New Zealand-built bus for two months before deciding whether to proceed by adding more buses with similar power-trains. The test bus is smaller than typical American transit buses and if New York buys more they will probably the standard-sized units with the turbine hybrid system.
