Five new Gillig 40-foot low-floor diesel-electric hybrid buses, which entered service in mid-April, are expected to deliver 30 percent fuel savings. The vehicles feature beltless alternators, where the electrical system pulls power from the hybrid batteries, and independent alternators feed power to the air-conditioning systems.
