Workhorse Custom Chassis is going out of business and is due to shut down this month, according to Heavy-Duty Trucking magazine. Navistar spokesman Steve Schrier confirmed the news.
Navistar's eStar electric van, though managerially connected to Workhorse, remains an active product, Schrier said.
Workhorse was started in 1998 by investors who took over production and sales of General Motors' popular P-series Stepvan chassis when GM dropped it. GM gasoline and diesel engines powered vehicles which, like competitors' chassis, got bodies from outside suppliers. Large delivery fleets like FedEx, UPS and Frito-Lay were among its customers. Navistar acquired Workhorse seven years ago.
Schrier said Navistar would continue to provide warranty and parts and service support for existing Workhorse chassis.
Navistar's website no longer lists Workhorse as one of its truck brands. A newly redesigned website now lists only International and Mahindra International as Navistar's truck brands.
Workhorse's site is still active.
