UQM Technologies Congratulates Proterra on Setting Record with Battery-Electric Transit Bus

UQM Technologies Inc. (NYSE MKT: UQM) congratulates Proterra for setting a record for the most miles traveled in a day by a battery-electric transit bus. Proterra uses the highly efficient UQM Technologies’ PowerPhase HD® electric propulsion system for its all-electric buses to achieve this incredible fuel economy and superior mileage.

Proterra reports that it has recently tested a production bus that set a record for battery electric buses by traveling more than 700 miles in 24 hours. It also had outstanding efficiency during this test and achieved nearly 27 MPGe – the rating system used by the U.S. EPA to compare energy consumption of electric, plug-in electric and similar alternative-fuel vehicles with the fuel economy of vehicles powered by conventional internal-combustion engines. Proterra reports that the MPGe realized in this recent test is nearly six times better than a diesel-powered bus and seven times better than a CNG-powered bus.

“This achievement by Proterra demonstrates the efficiency of UQM propulsion systems in all-electric buses, as well as the durability,” said Eric R. Ridenour, President and Chief Executive Officer of UQM Technologies Inc. “Proterra continues to grow their presence in the marketplace with buses now running in six major U.S. markets, with more on the way, all exclusively powered by our electric propulsion system, providing efficient and reliable public transportation.”
