International LT Series

International's aero flagship for the highway.

Launched on September 30, 2016 in Las Vegas as International's driver-centric Class 8 on-highway flagship and the replacement for the 10-year-old ProStar, the LT (for Line-haul Tractor) debuted with the new 2017 Cummins X15 rated up to 565 hp in the performance series. Its reworked aerodynamics delivered roughly 7% better fuel economy than a 2017 ProStar with the Cummins ISX15, and the Bendix Wingman Advanced collision mitigation system came standard on every model in the series.
