Workhorse Group Incorporated is an American manufacturing company based in Cincinnati, Ohio, currently focused on manufacturing electrically powered delivery and utility vehicles.
The company was founded in 1998 by investors who took over the production of General Motors’ P30/P32 series stepvan and motorhome chassis. By 2005, they were taken over by Navistar International, which had been selling them diesel engines. Navistar then shuttered the plant in 2012 to cut costs after having suffered heavy losses.
In March 2015, AMP Electric Vehicles took over Workhorse Custom Chassis, changing the company name to Workhorse Group Incorporated, and began offering a range of electrically powered delivery vans. [source]
