International Motors Sets New Standards with the 2027 S13 Integrated Powertrain for Trucks

International Motors Enhances Truck Performance with 2027 S13 Integrated Powertrain

International Motors, LLC has officially announced that its innovative 2027 S13® Integrated Powertrain fully complies with the U.S. Environmental Protection Agency's (EPA) emissions standards set for the upcoming model year. This cutting-edge powertrain, which underwent a complete design overhaul starting in 2017, is meticulously crafted to meet the stringent regulatory requirements that emphasize simplicity, performance, and reliability.

The 2027 S13 Integrated Powertrain incorporates over 90% of the hardware from the existing model, assuring customers they will benefit from familiarity in service tools, parts, and technician training. This consistency means that drivers can expect similar fuel efficiency, operational experience, and overall powertrain weight in relation to the current S13 model, fostering operational continuity and reliability.

Key Technical Specifications and Changes

The transition from the 2024 to the 2027 standards reveals significant alterations in emissions and powertrain technology. For example, the nitrogen-oxide (NOx) limits have been drastically reduced from 0.20 g/bhp-hr in 2024 to a mere 0.035 g/bhp-hr in 2027. Additionally, the 2027 model eliminates the need for Exhaust Gas Recirculation (EGR), streamlining the aftertreatment process to a dual-stage system without pre-heating.

Other noteworthy advancements include shifting to an upgraded electrical architecture. The 2027 powertrain will now utilize a 12V electrical system for the cab while incorporating a 24V architecture for the powertrain to enhance cold-crank performance and durability. This harmonized approach ensures that all powertrain components operate effectively and efficiently.

The commitment to sustainability is evident with the approval for R100 renewable diesel, which minimizes the carbon footprint without requiring any additional hardware modifications. Furthermore, ongoing trials to assess compatibility with B100 biodiesel emphasize International Motors' dedication to practical, eco-friendly solutions.

Insights from Leadership

Executive Vice President of Commercial Operations, Dan Kayser, commended the company's readiness for the EPA 2027 standards, assuring customers that they will not be faced with unforeseen challenges. He stated, “Our customers won't face surprises, only the same proven powertrain. Our solution provides reliability without unnecessary complexity.”

The S13 Integrated Powertrain's design emphasizes a compact and efficient structure that adheres to NOx regulations while ensuring ease of use. Fleets across North America have already logged over 700 million miles with this powertrain, showcasing its outstanding performance in fuel efficiency, reliability, and drivability.

Looking Ahead: A Vision for Innovation

International Motors is at the forefront of innovation in the truck industry, having engineered its S13 Integrated Powertrain with forward-thinking in mind—anticipating regulatory changes long before they materialized. This foresight empowers fleets with a tried-and-true compliance solution and maintains their competitive edge for EPA 2027 and beyond.
