Oak Park-based Azure Dynamics Corp. (OTCQX: AZDDF) Monday announced an order for 10 hybrid buses from the Pennsylvania Department of Transportation.

There's also an option for 15 additional buses at a later date.

Azure develops hybrid electric and electric powertrains for commercial vehicles. PennDOT has ordered the 18-passenger Azure/StarTrans Hybrid Para-transit Citibus for delivery in later this year.

"Azure's hybrid technology continues to gain traction with proactive fleet managers who value our performance, significant fuel economy improvements, emissions reductions and long-term maintenance cost savings," said Scott Harrison, Azure Dynamics' CEO. "We see the PennDOT order as further validation that our technology answers stringent market demands."

The Azure Series-Hybrid CitiBus system specified by PennDOT has unique attributes like engine-off driving while electronically supporting key ancillary functions like air conditioning, power steering and braking. The powertrain, with a GM Vortec 4.8-liter engine, offers over a 40 percent improvement in fuel economy, and a 30 percent reduction in carbon emissions in city conditions. The powertrain also offers a 25 percent reduction in engine maintenance and a 75 percent reduction in brake maintenance versus conventionally equipped competitors.

The first 10 Azure Dynamics Para-transit hybrid buses ordered by PennDOT will be operated by Rabbit Transit in York County and will expand its shared-ride program.
