Overview

Sharing its NGV (Next-Generation Vehicle) cab with the TranStar, LoneStar, and DuraStar, the ProStar was developed as a $300 million project to produce the most fuel-efficient Class 8 truck in North America, along with improving driver ergonomics and reducing maintenance complexity. For both day-cab and multiple sleeper-cab configurations, the ProStar was based on a 122-inch BBC dimension with a set-back front axle. The model line is powered by the MaxxForce 11 and 13 diesels, along with the Cummins ISX15 diesel. For 2015, Navistar introduced its N13 diesel as an option, replacing the MaxxForce engines. In 2010, the ProStar was renamed the ProStar+ as part of a model revision. Coinciding with emissions and fuel-economy refinements (including 700 pounds of weight reduction), the ProStar+ received updates to the interior to increase interior functionality. For 2015, a second revision was introduced as an option, making it the ProStar ES (Efficiency Specification). Coupled with further exterior aerodynamic enhancements, the ProStar ES achieved further fuel economy gains nearly through engine and transmission controls; an automated manual transmission was standard. In the New Zealand market, the successor to the ProStar is the RH, rather than the LT. Introduced in 2023, it utilities the RH cab and an updated right hand drive instrument panel

International LT (2017-present)

Introduced for 2017 production, the International LT serves as the replacement for the ProStar. Using the NGV cab (under a substantial revision), the LT improves its fuel economy over 7% over the ProStar+, intended to save an operator over $2000 per year in fuel costs. Replacing the ISX15, the standard engine is a Cummins X15, with a Navistar N13 returning as an option. Again configured for long-distance highway use, the LT is produced in day-cab and sleeper-cab configurations.
