FedEx Corp. (NYSE: FDX) announced the expansion of its alternative-energy vehicle fleet with the first all-electric FedEx parcel delivery trucks in the United States. Four purpose-built electric trucks—optimized for electric operation from the wheels up—are slated to hit the road in the Los Angeles area starting in June, joining more than 1,800 alternative-energy vehicles already in service for FedEx around the world.

“FedEx has a history of changing what’s possible, both in the innovative services we offer customers and in the way we offer those services,” said John Formisano, vice president, Global Vehicles, FedEx Express. “In 2004, we were the first global company to invest in hybrid-electric commercial trucks, and now we’re introducing the even cleaner all-electric parcel delivery truck. We’re making these investments, and invite others to join us, so that together we can speed the transition to a cleaner transportation system.”

Rather than creating its own proprietary technology, FedEx is again turning to the marketplace to spur solutions that can rapidly be scaled up to provide affordable and reliable service to a wide range of delivery truck operators. It is purchasing its first North American all-electric vehicles from two different suppliers to evaluate the robustness of this technology for demanding daily FedEx Express deliveries in the Los Angeles area and provide information to help guide future FedEx vehicle purchases.

Two of the new all-electric trucks come from Navistar, and are being assembled in Indiana. These are based on the Modec design already operated by FedEx in Europe. Ten such Modec vehicles serve FedEx routes in London and five more are on order for Paris.

Another pair of electric vehicles is being purchased from a different manufacturer for delivery to the Los Angeles area later in 2010. Both sets of electric vehicles are designed with a range that allows many FedEx Express couriers to make a full eight-hour shift of deliveries before their vehicles need recharging.

By the end of June, the FedEx alternative energy fleet will have grown to 1,869 vehicles in service around the world, helping to diversify and expand the all-electric and hybrid-electric vehicle market around the globe. Beyond the nine new electric trucks to be deployed in Los Angeles and Paris, FedEx has purchased ten additional hybrid-electric vehicles that will be added to its California fleet throughout the spring, based in Oakland.

FedEx currently operates the largest hybrid fleet in the transportation industry, along with one of the largest alternative energy vehicle fleets, and is committed to improving its overall vehicle fuel efficiency 20 percent by 2020.
