Q4 2025 Truck Production Climbs 3.7%
Sign-up for TPI ReportsThe Power Systems Research Truck Production Index (PSR-TPI) increased from 107 to 111, or 3.7%, for the three-month period ended Dec. 31, 2025, from Q3 2025. The year over-year (Q4 2024 to Q4 2025) loss for the PSR-TPI was, 113 to 111, or -1.8%.
The PSR-TPI measures truck production globally and across six regions: North America, China, Europe, South America, Japan & Korea and Emerging Markets. This data comes from OE Link,™, the proprietary database maintained by Power Systems Research.
All Regions. In 2026, all regions are expected to see some level of improvement in the MHCV segment. After low levels of production in Europe and North America in 2025, a slight increase in demand in 2026 is expected as both regions recover and should see stronger demand in 2027 and 2028. All other regions are expected to see improvement as well.
Global. Globally, medium and heavy commercial vehicle production is expected to decline by 3.7% this year over 2025. A moderate softening of the global economy along with negative impacts from increased tariffs had placed pressure on vehicle demand last year but market conditions are stabilizing heading into 2026.

Tesla Semi Lines Up for $165M in California Incentives
Chris Fisher The update was initially reported by The Los Angeles Times.
Tesla reportedly is positioned to receive roughly $165 million in California clean-truck incentives for its Semi.
As per the Times, the Tesla Semi’s funding will come from California’s Hybrid and Zero-Emission Truck and Bus Incentive Project (HVIP), which was designed to accelerate the adoption of cleaner medium- and heavy-duty vehicles. Since its launch in 2009, the HVIP has distributed more than $1.6 billion to support zero-emission trucks and buses across the state.

2026 Growth of 4.9% Seen in Truck Production
Chris Fisher Medium and heavy truck production in North America is expected to increase by 4.9% this year compared with 2025. While class 8 truck production is expected to increase by 6.1% this year, the industry continues to be negatively impacted by the weight of the tariffs, low freight demand, excess truck capacity and relatively high finance rates which is expected to continue through at least the first half of the year.
With regard to the implementation of the phase 3 GHG emission regulations, it will be later in the spring before the EPA finalizes any revisions to the standards. Many in the industry believe the EPA will retain the 0.035 g/hp-hr standard along with the 2027 implementation date but cancel the extended warranty requirements which would have added significant up-front cost to the trucks.

EPA Won’t Delay 2027 NOx Rule, Plans Changes
Chris Fisher The U.S. Environmental Protection Agency is moving forward with the 2027 timeline for its heavy-duty NOx rule—currently set to take effect with the 2027 model year—but says changes are in store.
The American Trucking Associations (ATA), National Tank Truck Carriers, Truckload Carriers Association, and 49 state trucking associations in August penned a letter to EPA, asking the regulator to push implementation to 2031, citing “substantial compliance costs and operational burdens at a time when the trucking industry is already contending with historically difficult market conditions.”
Administrator Lee Zeldin in March announced that the EPA was reevaluating the Biden-era 2022 Heavy-Duty Engine and Vehicle rule that regulates oxides of nitrogen (NOx) and other emissions beginning with Model Year 2027.

Trucking Recovery To Be Driven by Supply Side?
Chris Fisher The signs of a freight recovery that appeared early this year are gone, replaced by a tough market where recovery will have to come from a supply-side correction, American Trucking Associations’ Chief Economist Bob Costello said at ATA’s 2025 Management Conference & Exhibition in San Diego.
Costello delivered a blunt and sobering economic warning: new tariffs, persistent stagflation, and a slowing labor market have created “absolutely unsustainable” conditions for many carriers, and the only way out, at least near-term, is to erase capacity from the highway.
“It’s not easy to talk about because it’s people’s livelihoods, but it’s a necessary evil,” Costello said, noting that freight demand is unlikely to improve anytime soon. “This has got to be a supply-driven change in the market.”
The current 18% effective tariff rate, nearly six times higher than it was during the first Trump administration, is a level not seen since the 1930s. Costello warned that the industry is only in the “bottom of the second or top of the third inning” of feeling the impact. “Any benefits of putting tariffs on foreign goods… are years in the future, but the cost hits much quicker,” he said.

The PSR-TPI measures truck production globally and across six regions: North America, China, Europe, South America, Japan & Korea and Emerging Markets.
This data comes from OE Link™, the proprietary database maintained by Power Systems Research.
All Regions. In 2025, Medium and heavy commercial vehicle production in South America, Greater China, South Asia and Japan/Korea are expected to increase while European and North American production is expected to decline significantly this year over 2024. Truck demand in North America and Europe is expected to show slight improvement in 2026.
Global Index. Globally, medium and heavy commercial vehicle production is expected to decline 3.2% this year over 2024. A moderate softening of the global economy along with negative impacts from increased tariffs has placed pressure on vehicle demand this year. However, global truck demand is expected to see some improvement in 2026. PSR

Truck Demand Expected To Remain Soft into 2026
Chris Fisher How things have changed. Less than a year ago the industry was gearing up for a huge 2026 class 8 truck pre-buy ahead of the phase 3 GHG emission regulations that would add significant cost to the price of a truck. Road freight was expected to rebound after the post covid freight recession, and the heavy truck replacement cycle was expected to begin. OEMs filled dealer lots in anticipation of strong demand starting in early to mid-2025 and lasting through all of 2026.
As a result of very strong freight shipments and supply chain disruptions during the Covid era, fleets were purchasing as many trucks as possible which resulted in very high truck sales from 2022 – 2024. This resulted in truck overcapacity within the market.

EPA Plans To Drop Phase 3 Emission Regulations
Chris Fisher In July, the Trump administration proposed a draft rule rolling back the Greenhouse Gas Phase 3 rule, among the last of – if not the biggest – looming Biden-era emissions regulations facing the trucking industry.
The proposal was announced jointly with Environmental Protection Agency Administrator (EPA) Lee Zeldin’s call to revoke the Endangerment Finding that has allowed presidential administrations to regulate greenhouse gases since 2009.
The repeal of greenhouse gas regulations is a long road that includes a lengthy rulemaking process and likely numerous legal challenges.
