Colorado Transit Fleet’s Hybrid Buses Getting Some Attention


The Denver Regional Transportation District (RTD) is working with UQM Technologies Inc. to inspect and refurbish components in RTD's fleet of 30 hybrid-electric transit buses.

The vehicles, which have logged more than a million miles in regular service since 2004, use UQM's PowerPhase Select electric generators and controllers in their hybrid powertrains. All of these components will be checked and repaired or replaced, if necessary, and then tested.

‘This pioneering fleet of hybrid buses was one of the earliest hybrid vehicle programs in the country, and the amount of miles these hybrid systems have traveled over nearly a decade is impressive,’ says Eric R. Ridenour, president and CEO of UQM.

UQM's products are also integrated in Hino electric city buses, Proterra electric composite transit buses, Electric Vehicles International all-electric medium-duty trucks and Boulder EV delivery vans.
