FORT STEWART, GA - Of the nearly 500 hybrid-electric vehicles (HEVs) already delivered to Army installations, seventeen are now part of Fort Stewart-Hunter Army Airfield's general dispatch fleet or maintenance vehicles. The Army began leasing hybrid-electric vehicles from the General Service Administration, the federal agency that purchases non-tactical vehicles for the federal government, about six months ago.

"We told GSA we'd take as many hybrids as they can give us," said John Brinton, Transportation Motor Pool fleet manager with the Directorate of Logistics. "We currently have six Ford Fusions and 11 Chevrolet Silverados, all hybrid-electric vehicles. We hope to get another 10 or 20 next year, probably in the spring."

Each car taken into the Army's general dispatch fleet is replaced every three years or 36,000 miles. Trucks and light vans are replaced every six years or 72,000 miles, according to a Stewart-Hunter statement.
