Azure Dynamics series hybrid bus completes US government tests

Public transit agencies in the US will now be able to buy series hybrid shuttle buses from Azure Dynamics and get federal subsidies. One of the CitiBus Hybrid HD Senator buses successfully completed a durability test program at a facility in Altoona, Pennsylvania. The test simulates seven years of use in an urban transit environment. Like the Chevy Volt, the Azure bus is driven only by the electric motor. The motor gets electricity either from a battery pack or the engine-generator set which uses a GM 4.8L V-8.
