North American Class 8 truck orders increased in September as fleets began shifting their focus toward model-year 2027 equipment, while uncertainty continues to surround emissions regulations and truck pricing.
Preliminary Class 8 net orders reached 21,300 units in September, an 18% increase from August and 3% above the same month last year, according to FTR Transportation Intelligence.
The month-to-month increase was smaller than the seasonal gain typically recorded in September. Nevertheless, FTR said underlying demand for heavy-duty trucks remained “fairly solid,” supported by fleet replacement requirements, tight capacity and firmer freight rates.
Through September, Class 8 orders totaled 263,499 units year to date, up 95% from the same period in 2025. Over the previous 12 months, orders reached 351,244 units.
The shift toward 2027 trucks begins
September also marked an important transition for the heavy-duty truck market as manufacturers began moving their order books toward model-year 2027 equipment.
According to FTR, the EPA 2027 nitrogen oxide emissions-related pre-buy period has ended, while surcharge-free production slots for model-year 2026 engines are essentially sold out.
Some manufacturers may have closed their 2026 order books in early to mid-August before opening orders for 2027 models. That timing may have pushed some previously deferred fleet purchases into September.
At the same time, truck and engine manufacturers are taking different approaches to meeting the upcoming emissions requirements, including whether to rely on nonconformance penalties, or NCPs.
The uncertainty could have a significant impact on fleet costs.
Dan Moyer, FTR senior analyst for commercial vehicles, estimates that NCPs could translate into an additional $6,000 to $7,000 per Class 8 truck for fleets. By comparison, an engine fully compliant with the new emissions requirements could carry an estimated $8,000 to $12,000 upcharge.
“Truck and engine manufacturers have announced varying strategies for handling the emissions transition, and some have not yet made their plans clear,” Moyer said.
He added that the final EPA rule could materially change the economics of those strategies. Higher NCPs would reduce the cost advantage of using current-generation engines, while lower NCPs would make that approach more attractive.
The outcome could affect 2027 engine availability, fleet acquisition costs and the mix of technologies ultimately chosen by operators.
Truck pricing remains uncertain
Pricing is another unresolved issue as manufacturers open model-year 2027 order books before the EPA finalizes its 2027 NOx regulation.
Truck prices could therefore change once the final rule is issued, adding another element of uncertainty for fleets planning their next equipment purchases.
FTR expects Class 8 orders over the next month or two could remain close to year-ago levels while fleets wait for greater clarity on regulatory requirements and their associated costs.
For carriers, the decisions made during this transition will extend beyond the timing of equipment purchases. The cost of compliance, availability of engines and the technology selected for new trucks could all influence fleet acquisition strategies as the industry moves into the 2027 model year.
Why it matters: Class 8 truck demand remains relatively firm heading into the 2027 model year, but uncertainty surrounding EPA emissions requirements, engine availability and the cost of compliant equipment could significantly influence fleet purchasing decisions in the months ahead.
