Proterra is answering the international call for efficient, cost-effective and environmentally responsible heavy-duty vehicle solutions. Headquartered in Greenville, SC, Proterra is a leading designer and manufacturer of heavy-duty drive and energy storage systems, vehicle control systems and complete transit buses. Proterra's systems are scalable to all forms of commercial buses and Class 6-8 trucks. Proterra's initial product, a 35' battery-electric transit bus, has been designed from the ground up to enable a world's first ever solution for transit agencies to replace conventional diesel buses on a one-for-one basis with all-electric buses operating 24/7. This is accomplished by combining Proterra's light-weight composite body, highly efficient ProDrive(TM), advanced TerraVolt(TM) energy storage system and on-route rooftop FastCharging(TM) station to charge the bus in 5-10 minutes. The vehicle achieves between 18 and 29 miles per gallon diesel fuel equivalent fully loaded with 68 passengers - 500% better than a comparable diesel bus.
