Workhorse Custom Chassis launched its new walk-in truck at this week’s National Truck Equipment show in Indianapolis. Called the W62, the new truck (chassis by Workhorse, bodies by Morgan Olson or Utilimaster) extends the capacity of the Workhorse walk-in lineup with 19,500 lbs. and 23,500 lbs. GVWR models.Of special interest is that Workhorse’s initial offering in these weight classifications will be gasoline powered. It will use General Motors’ 8.1 L Vortec V8 gasoline engine mated to the five-speed Allison 1000HS (for 19,500 lb. GVWR) or Allison 2200HS (for 23,500 lb. GVWR) transmission. The big block Vortec produces 310 horsepower and 455 lb.-ft. of torque. Workhorse says it is the only chassis manufacturer to power a gas walk-in at these GVWRs. A diesel version using International’s MaxxForce 5 V6 engine will be launched by mid summer. With the diesel addition, Workhorse will offer both gas and diesel choices for GVWRs ranging from 9,400 lbs. to 23,500 lbs., with wheelbases from 125 inches to 218 inches. The W62 comes with wheelbases of 157, 178, 190, 208 and 218 inches.Parcel delivery, utilities, textile/uniform rental, municipalities, newspapers and mobile tool sales are some of the vocations that Workhorse expects to compete in more effectively with the higher GVWR classifications.
