When you walk a dealer lot today, many of the compact and midsize SUVs Americans buy most often—Toyota RAV4, Honda CR-V, Ford Bronco Sport, Chevrolet Equinox, Jeep Compass—are regulated as light-duty trucks even though they behave like family haulers. That label matters because Corporate Average Fuel Economy (CAFE) sets separate mpg curves for passenger cars and for trucks. In the final rule the U.S. Department of Transportation and the National Highway Traffic Safety Administration (NHTSA) released in late September 2026, a long-planned tightening of those definitions lands on model year 2030, moving a large share of crossovers into the passenger-car bucket unless automakers redesign them to meet truck criteria.
What regulators changed and when it starts
The rule resets CAFE standards for model years 2022 through 2031 and is packaged under the administration’s “Freedom Means Affordable Cars” initiative. Fleetwide, NHTSA targets about 34.9 miles per gallon by 2031—well below the roughly 50.4 mpg trajectory under the 2024 Biden-era framework, but still an increase from the 30.1 mpg fleet average NHTSA cites for model year 2024. Buried in the same 892-page document is the piece most shoppers will eventually feel: starting with 2030 models, NHTSA will stop treating many crossovers as trucks by default.
Industry comments pushed the effective date from 2028 to 2030, so 2028 and 2029 model years still follow today’s classification logic. If you are cross-shopping a 2029 RAV4 against a 2030 redesign, the regulatory label on the window sticker may differ even when the vehicle looks identical on the outside.
Why so many “trucks” were really cars
NHTSA’s filing is blunt about market reality: roughly 68% of the light-duty fleet currently meets the truck definition, yet most of those vehicles rarely leave pavement and are bought to move people, not cargo. Automakers historically added features—fold-flat third rows, modest ground clearance, styling cues—to qualify for the truck category and its less demanding mpg curve while selling car-like products. Environmental and consumer groups have argued for decades that the loophole distorted both fuel use and product planning. The 2030 reclassification is, in that sense, a bookkeeping correction that also reshuffles compliance math for every major brand.
On paper, the regulated fleet mix flips from about 70% trucks and 30% passenger cars to roughly the opposite. Crossovers that helped pull truck averages up will now count toward the stricter passenger-car target—about 40.2 mpg for that category in 2031, versus about 26.4 mpg for vehicles that remain classified as light-duty trucks.
Nameplates most likely to move
According to NHTSA filings cited in industry coverage, high-volume crossovers slated to shift include the Toyota RAV4, Honda CR-V, Ford Bronco Sport, Chevrolet Equinox, and Jeep Compass. Subaru’s U.S. lineup—Forester, Crosstrek, Outback—is expected to land in the passenger-car column unless designs change materially. The same broad shift applies to much of Kia’s and Mazda’s crossover portfolios, including models such as the Telluride and CX-5 that buyers treat as SUVs but regulators will soon treat as cars.
Pickup trucks, body-on-frame SUVs, and vehicles engineered for serious towing or off-road use are the ones most likely to stay in the truck category. That leaves a leaner truck bucket dominated by pickups and true off-roaders, which can pull the truck average down even as the passenger-car average gains heavier crossovers.
The two paths to remain a light-duty truck
NHTSA narrows truck eligibility to two measurable routes. First, combined towing and payload capacity of at least 8,500 pounds—think heavy-duty hauling, not a roof box and two bikes. Second, documented off-road capability passing four eligibility tests NHTSA spells out in the rule. Fold-down third rows alone will no longer nudge a suburban crossover into the truck column.
Automakers can respond in several ways: add genuine capability (with weight and cost trade-offs), accelerate hybrids and other efficiency tech on crossovers, or accept that those models now count against the passenger-car curve. Hyundai executives told reporters the company will adjust product plans rather than unwind U.S. investment, leaning on hybrid volume. GM publicly warned that reclassification could distort the market more than regulators modeled, while still continuing electrified development independent of the headline mpg numbers.
What drivers should watch on the lot
Do not expect overnight disappearances of compact SUVs—they remain America’s preferred shape. You may, however, see marketing shift toward tow packages, skid plates, or all-terrain trims on models that must defend truck status, or conversely see automakers lean into hybrid powertrains and aero tweaks on models that will be regulated as cars. Trim walkarounds that used to highlight cosmetic “adventure” add-ons may start quoting tow ratings and payload figures instead.
Congress separately zeroed out CAFE non-compliance penalties in 2025, so the fleet mpg figures function more as planning targets than as fines-backed mandates for now. NHTSA can restore penalties only if a future transportation secretary raises them above zero. Even with weak enforcement, the classification change still steers engineering budgets because brands compete on efficiency labels and because state-level greenhouse-gas programs— overseen by the U.S. Environmental Protection Agency (EPA) for tailpipe rules—can interact with federal mpg planning.
If you are comparing model years or shopping used inventory, run the VIN through government recall data before you sign, because design changes tied to new definitions often arrive mid-cycle; CarDiary’s VIN check keeps that lookup alongside your other vehicle records so you are not juggling browser tabs at the desk.
How this differs from the headline mpg rollback
Another CarDiary piece walks through the broader September 2026 CAFE reset and what the lower 2031 fleet target means for powertrain planning. This article isolates the crossover reclassification because it changes which mpg curve applies to the vehicle on your driveway, not just the average on an automaker’s spreadsheet. Analysts note the reclassification can make a “softer” fleet target harder to hit for truck-heavy lineups even when the numeric mpg goal looks modest relative to 2024 performance.
Consumer Reports and other policy watchers point out that advocates had sought tighter truck definitions for years; ironically, the industry now faces that tightening inside a rule that otherwise relaxes long-term mpg stringency and eliminates CAFE credit trading from model year 2028. For shoppers, the practical takeaway is simpler: starting with 2030 models, the CR-V-like crossover you buy may legally be a passenger car, and the engineering choices that follow are about real capability and real efficiency—not checkbox features aimed at a regulatory category.
