Unveiled in September 2017 for the 2018 model year as the replacement for the steel-cab WorkStar, the HV (Heavy Vocational) is powered by the standard International A26 12.4L big-bore engine. It brought over-the-road comfort to vocational work by borrowing its cab interior from the LT long-haul and RH regional-haul tractors, and is rated up to 73,000 pounds GVWR for dump, mixer and refuse duty.
