The WorkStar features a DT-466 based natural gas engine developed in conjunction with Emissions Solutions Incorporated (ESI) of McKinney, Texas. ESI offers engine ratings from 175-300 horsepower with 460-860 lb.-ft. torque. The engines are capable of supporting both liquefied and compressed natural gas. The natural gas powered WorkStar model with either frame mounted or back-of-cab mounted natural gas tanks is available for customer ordering through International truck dealers and will be built at Navistar's Garland Assembly Plant and Truck Specialty Center in Garland, Texas.
