Cummins Inc of Columbus, Indiana, has provided eight all-electric drivetrains installed in vans for operation with the United States Postal Service (USPS). The fully electric Cummins PowerDrive equipped vans are expected to eliminate vehicle emissions and reduce fuel and maintenance costs. The pilot programme, made possible by a grant from the California Air Resources Board to the San Joaquin Valley Air Pollution Control District (SJVAPCD) and administered by CALSTART, is to place the zero-emission vehicles in Fresno and Stockton. Cummins is to also provide operator training, vehicle support and data collection.
           

The vans have an all-electric range up to 85 miles with a full load on urban drive cycles typical of USPS collection vehicles. The direct drive architecture provides improved performance over the gasoline-powered version in critical areas of power and efficiency. The vans use the same charging system as passenger electric vehicles (SAE J1772 Level 2) and can reach a full charge in about eight hours, making overnight charging a viable option.
