What Happened
The 2027 S13 Integrated Powertrain passes EPA's stringent 2027 model year emissions rules, including a NOx limit of 0.035 g/hp-hr, down from 0.20. International says the powertrain retains 90% of existing hardware, so service tools, parts, and training remain consistent.
- 0.20 (2024) → 0.035 (2027)
- Yes (2024) → Eliminated (2027)
- R100 Approved (both)
700 million
Across North America, proving reliability and fuel efficiency.
“We've been preparing for EPA 2027 for years. Our customers won't face surprises, only the same proven powertrain.”
Why this matters
Fleets can comply with stricter NOx regulations without major redesign, ensuring operational continuity and support for renewable diesel, reducing carbon footprint.
