The Trump administration’s announced CAFE changes would replace several older tests for light-truck classification with a towing-and-payload measure beginning in model year 2030. The change could move some crossovers into the passenger-car category, though its practical effect depends on how the standards are enforced and how automakers respond.
The Trump administration’s announced changes to U.S. fuel-economy rules would replace several longstanding tests for classifying vehicles as light trucks with a measure based on towing and payload capacity, according to a report by The Drive. Starting with the 2030 model year, the shift could classify some crossovers now treated as trucks as passenger vehicles, subjecting them to more stringent CAFE standards under the proposed framework.
The National Highway Traffic Safety Administration’s new measure, called Light Duty Work Factor (LDWF), adds a vehicle’s towing capacity to its payload capacity. A light-duty vehicle would qualify as a non-passenger automobile, or light truck, if its calculated LDWF is at least 8,500 pounds. Gross vehicle weight rating would be used to calculate payload, but would not otherwise determine the classification.
The change would replace older qualification routes that included passenger and cargo-volume tests, four-wheel drive or a weight threshold combined with off-road measurements. Those criteria were part of the system established in 1975. NHTSA’s report says the alternative pathways were omitted because designs with non-passenger or off-highway features could skew an analysis of whether a vehicle was chiefly designed to transport property.
The Drive reports that large trucks and SUVs are expected to meet the new threshold, while some midsize crossovers could move into the passenger-vehicle category. The administration’s package also eases emissions requirements for vehicles classified as light trucks. The article says the immediate effect may be limited, in part because CAFE enforcement is currently weak; it points to automakers dropping features such as auto stop-start as a more visible near-term change.
Crossovers Face a New Classification Test
The classification matters because CAFE standards differ by vehicle category. If a crossover no longer qualifies as a light truck, it would be assessed as a passenger vehicle under the new framework, where the requirements are tighter. That could affect how manufacturers balance efficiency, towing capability and vehicle design in a segment that includes models with substantial towing capacity but more modest payloads.
The adjustment also complicates a simple reading of the package as a uniform relaxation. While the light-truck category gets easier emissions requirements, narrowing which vehicles count as trucks could shift some models into a more demanding category. The actual effect on vehicle offerings and fuel economy will depend on the final rules, manufacturer decisions and enforcement.

A 1975 Definition Reaches Its Limit
The current light-truck classification traces to rules adopted in 1975, when the category was intended to account for vehicles used for commercial or other non-passenger purposes. The criteria included features such as open beds, cargo volume exceeding passenger volume, four-wheel drive and specified ground-clearance and approach-angle measurements.
According to NHTSA’s report, the original alternative pathways no longer reliably distinguish utility vehicles from passenger-focused models. The Drive says automakers have been able to use the off-road criteria to qualify vehicles for the less stringent truck standards. The new LDWF formula is designed to measure utility through a vehicle’s ability to carry or tow property rather than its size or off-road dimensions.
Enforcement and Model Effects Remain Open
The available report does not identify which specific crossover models would fall below the 8,500-pound LDWF threshold, or how automakers might alter towing and payload ratings in response. The full real-world effect will also depend on how the rule is finalized and applied.
The Drive describes current CAFE enforcement as weak and says the changes may have little near-term impact. The supplied material does not specify when enforcement might change or how much fuel use or emissions would shift as a result. The anticipated classification effects should therefore be treated as projections, not confirmed outcomes for individual vehicles.
The 2030 Model-Year Deadline
The classification formula is slated to apply beginning with the 2030 model year. Before then, the key milestones are the completion and implementation of the administration’s rule changes and decisions by automakers about which vehicles to offer and how to rate their capabilities.
As those details emerge, vehicle-specific classifications will show which crossovers move into the passenger category and whether the revised standards change manufacturers’ product plans. The source material does not give a separate enforcement timetable or identify a next agency action date.
Key Questions
What is changing in the CAFE light-truck rules?
Starting with the 2030 model year, eligibility would be based on a Light Duty Work Factor that adds payload and towing capacity. A vehicle would qualify as a light truck at 8,500 pounds or more.
Could the rule affect crossovers?
Yes. The Drive reports that some midsize crossovers could fail to meet the new threshold and be classified as passenger vehicles. Which models would change category has not been specified.
Will large trucks and SUVs be reclassified?
The report says large trucks and SUVs are expected to meet the threshold, including some that could qualify through towing capacity alone. Individual vehicle outcomes are not listed in the source material.
When would the new classification begin?
The change is slated to begin with the 2030 model year. The supplied report does not provide a separate enforcement timeline.
