Demand for new Class 8 trucks remained remarkably strong in August, despite a month-to-month decline in orders, as North American fleets continued to position themselves ahead of the industry’s transition to tougher emissions requirements in 2027.
Preliminary figures from FTR Transportation Intelligence put August Class 8 net orders at 18,200 units. That represented a 19% decline from July, but orders were still 42% above August 2025 levels.
According to FTR, the monthly decrease was largely in line with normal summer seasonality. It also reflected the conclusion of the 2026 order season and the final phase of fleet purchasing ahead of the Environmental Protection Agency’s 2027 nitrogen oxide emissions requirements.
Despite the August decline, the broader picture remains exceptionally strong. Class 8 orders were 111% higher through the first eight months of 2026 than during the same period in 2025, FTR reported.
Looking at the complete 2026 order season, which ran from September 2025 through August 2026, North American Class 8 orders rose 39% compared with the previous order season. A total of 350,677 Class 8 trucks were ordered across North America during the past 12 months.
2027 order books could provide a clearer demand signal
FTR cautioned against viewing August’s sequential decline as evidence that underlying demand is weakening.
Several truck manufacturers may already have exhausted their remaining 2026 production capacity by early or mid-August, while their 2027 order books had not yet opened. That situation would have limited the ability of fleets to place additional orders during the month.
FTR estimates that most, if not all, surcharge-free 2026 engine production slots have now been allocated, effectively bringing the EPA 2027 NOx pre-buy period to a close.
As a result, September could become a much more important indicator of genuine market demand. With manufacturers beginning to accept orders for 2027 equipment, fleets will have to make purchasing decisions without the same pre-buy dynamics that supported demand over the past year.
The focus is now shifting increasingly toward cost.
FTR estimates that noncompliance penalties — which would permit transitional sales of engines that exceed the new NOx limit — could add approximately $6,000 to $7,000 per engine. Those additional costs would likely be passed directly on to fleets.
Fully compliant EPA 2027 engines could involve an even larger manufacturer upcharge, estimated at between $8,000 and $12,000.
Manufacturers take different approaches to the 2027 transition
Truck manufacturers are not taking a uniform approach to the regulatory change, according to Dan Moyer, FTR senior analyst for commercial vehicles.
Some manufacturers intend to offer fleets a choice between fully compliant engines and current-generation engines subject to noncompliance penalties. At least one manufacturer, however, plans to offer only the fully compliant option.
“Overall, August marks the close of the 2026 order season and the effective end of the EPA 2027 NOx pre-buy,” Moyer said in a statement.
He added that fleet purchasing decisions will increasingly depend on engine selection, pricing and the timing of production as manufacturers open their 2027 order books.
ACT Research’s preliminary estimate for August Class 8 orders also indicated continued year-over-year strength.
Used Class 8 truck sales lose momentum in July
The used-truck market, meanwhile, showed some signs of cooling in July, although sales remained substantially higher than they were a year earlier.
ACT Research reported that same-dealer retail sales of used Class 8 trucks fell 2.5% from June. The decline was greater than normally expected from seasonal patterns.
Even so, July sales were 45% higher than in July 2025, highlighting the significant year-over-year improvement in demand for used equipment.
Prices also moved lower during the month. The average retail selling price for a used Class 8 truck fell 4% from June to $60,986.
ACT’s July summary showed that same-dealer sales were up 10% year to date compared with the corresponding period of 2025. Average prices were also 3% higher over the same period. At the same time, average vehicle mileage and age were both lower year over year.
“The July slowdown in used Class 8 retail sales was directionally consistent with seasonal expectations, but the magnitude was greater than usual,” Steve Tam, vice president at ACT Research, said in a statement.
Tam noted that auction and wholesale activity also weakened during July, contributing to lower overall market volumes. Nevertheless, year-to-date sales and equipment values continued to show resilience despite uncertainty surrounding regulatory changes and manufacturers’ product strategies.
Why it matters
The Class 8 market continues to show considerable purchasing strength, with both new and used equipment demand remaining well above year-ago levels.
However, the end of the EPA 2027 NOx pre-buy marks an important turning point. With surcharge-free 2026 engine slots largely filled and manufacturers beginning to open their 2027 order books, September could offer a clearer picture of the underlying health of the North American heavy-duty truck market.
For fleets, the next phase will be less about securing equipment ahead of the regulation and more about balancing engine technology, pricing and production timing as the additional costs of the 2027 transition become increasingly visible.
