Key Takeaways:
Traton executives said July 23 that International Motors plans a new cab update for its Class 8 on-highway trucks to boost North American market share.The push follows S13 powertrain rollout and comes after International’s 2025 Class 8 sales fell 13.8% year over year to 22,898 trucks.International has not detailed the cab redesign, but officials said updated cabs would complement recent engine changes and support future growth efforts.
Traton Group’s top executives promised an overhaul of the cabs of International Motors’ on-highway tractor portfolio July 23, linking the revamp to a push to win a greater North American heavy-duty truck market share.
Lisle, Ill.-based International’s Class 8 on-highway strategy is centered on the LT Series and RH Series, each of which is now available with the S13 engine and powertrain.
But during Traton’s second-quarter 2026 earnings call, Chief Financial Officer Michael Jackstein said a new cab was coming as the second part of the basis for the market share push.
“We are looking into, let’s call it a cab update, since the cab that we [have] right now, even though we developed a little bit in there, is quite old,” Jackstein told analysts.
A spokesperson for International could not provide more details immediately, but testing of a camouflaged new cab may have been spotted in the spring.
International sold 22,898 Class 8 trucks in 2025, a 13.8% year-over-year decrease and equating to an 11% share of the market. In 2024, the company won an 11.1% share of Class 8 retail sales, according to Omdia Automotive data.
As Jackstein and Traton Group CEO Christian Levin noted during the call, engines for International’s heavy-duty trucks have been updated.
International laid out plans for an S13 integrated powertrain complying with Environmental Protection Agency emissions requirements for 2027 model-year trucks in January.
Serial production of the S13 powertrain at the Huntsville, Ala., plant began in October 2023. The powertrain comprises the S13 engine, proprietary T14 automated transmission and a dual-stage aftertreatment system.

The S13 engine is part of a Traton-wide development program. Versions of the so-called Common Base Engine are used across Traton’s global truck brands. The Scania brand began production of the engine in 2022, while MAN followed in 2024.
But on the cab side, the flagship longhaul, on-highway LT Series tractor last saw an overhaul in August 2022 that focused on aerodynamic improvements.
The LT Series — introduced in September 2016 to replace the ProStar model — also saw an updated aero and software package introduced in October 2019.
LT Series tractors were originally offered with the Cummins X15 and Navistar N13 engines and debuted the International A26 engine in February 2017 to replace the N13.
The RH Series, meanwhile, saw an updated aero and software package introduced in October 2019. The regional-haul truck debuted in April 2017. International also launched a battery-electric version, the eRH Series, in April 2025, but the eRH Series was subsequently withdrawn less than six months later.
International also sells Class 8 HV Series and HX Series vocational trucks. The company launched a redesign of the HV Series in September 2024. Series production of the updated HV 509, HV 515, HV 609 and HV 615 models began in 2025.
