The International HV Series is the newest line of heavy duty vocational trucks that replaced the PayStar/5000 Series and WorkStar/7000 Series, starting in 2018. The trucks are available in configurations from 4x2 up to 8x6, with body to back of cab lengths (BBC) of 107" or 113".
The HV Series differs visually from the prior PayStar and WorkStars (in the same way as the new MV Series from the older DuraStars) by having a drop in the door frame at the front lower corner of the driver and passenger windows. This shows the one-piece window that is used on the HV versus the 2-pieces that made up previous models.
