Large SUVs sit at the intersection of expanding vehicle scale, improving fleet efficiency, and persistent crash-risk questions. The available U.S. evidence below uses EPA regulatory categories and IIHS size definitions, so “large SUV” is not interchangeable with every truck SUV or car SUV.
Key Large SUV Statistics
The most useful headline figures are:
- In U.S. model year 2023 production, truck SUVs represented 45% of new vehicles.
- In U.S. model year 2023 production, car SUVs represented 12% of new vehicles.
- In the United States, truck SUVs and car SUVs together accounted for 57% of model year 2023 production, although this is not an official large-SUV share.
- U.S. truck-SUV production rose from 20.6% in model year 2005 to 45.3% in 2023.
- U.S. truck SUVs averaged 24.7 real-world mpg in model year 2023.

Large SUV Production Scale and Market Trends
EPA’s production categories show how strongly SUV-shaped vehicles influence the U.S. new-vehicle market. They are regulatory and analytical classifications, not a direct count of consumer-defined large SUVs, sales, registrations, ownership, or vehicles on the road.
| EPA category or neighboring class | Model year 2023 U.S. production share | Definition note |
|---|---|---|
| Truck SUVs | 45% | Broader than consumer “large SUV” |
| Car SUVs | 12% | Includes many smaller crossovers |
| Truck SUVs + car SUVs | 57% | Derived combined share, not official large-SUV share |
| Pickups | 15% | Neighboring vehicle type |
| Overall truck regulatory class | About 62% | Includes truck SUVs, pickups, and minivans/vans |

Truck SUVs were a very small share of U.S. production in 1975, then reached 45% by 2023. The report’s longer-run description establishes the direction of change, but it does not provide a numeric 1975 endpoint in the supplied evidence.
EPA reports that truck-SUV production share increased from 20.6% in 2005 to 45.3% in 2023. That is a production-share trend, not a direct sales or fleet-ownership series.
Large SUV Fuel Economy and Emissions Data
EPA estimated that truck SUVs averaged 24.7 real-world mpg and 356 g/mi of real-world CO2 in model year 2023. These are category averages covering EPA’s truck-SUV definition rather than every vehicle marketed as a large SUV.
| Measure | 2005 | 2023 | Population and unit |
|---|---|---|---|
| Truck-SUV fuel economy | 16.7 mpg | 24.7 mpg | U.S. real-world category average |
| Truck-SUV CO2 | 531 g/mi | 356 g/mi | U.S. real-world category average |
| Truck-SUV production share | 20.6% | 45.3% | U.S. new-vehicle production |
Source: 2024 EPA Automotive Trends Report Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975.
Between model years 2022 and 2023, truck-SUV fuel economy improved by 0.4 mpg. EPA also estimated that all new U.S. light-duty vehicles averaged 27.1 mpg and 319 g/mi of CO2 in 2023, figures that provide fleet context rather than a large-SUV result.
EPA’s comparison shows car-SUV fuel economy increasing by 7.2 mpg from 2022 to 2023, with much of the change attributed to the influx of battery-electric vehicles. Car SUVs are distinct from truck SUVs, so this change should not be applied to large truck SUVs.
EPA states that larger vehicle footprint correlates with lower fuel economy and higher CO2 for internal-combustion and hybrid vehicles. That is a relationship finding without a single quantified causal effect or a large-SUV-only coefficient.
Large SUV Size, Weight, Power, and Footprint
The available national size benchmarks cover all new U.S. light-duty vehicles, not large SUVs alone. They are useful context for understanding the scale of the overall market, but they should not be presented as a measured average for a specific large-SUV group.
| Average new U.S. light-duty vehicle measure | 2022 | 2023 |
|---|---|---|
| Weight | 4,303 lb | 4,371 lb |
| Horsepower | 259 hp | 266 hp |
| 0–60 mph time | — | 7.3 seconds |
| Footprint | — | 51.8 sq. ft. |
Source: 2024 EPA Automotive Trends Report Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975.
Average new-vehicle weight increased by 68 pounds, from 4,303 pounds in 2022 to 4,371 pounds in 2023. Average horsepower increased by 7 hp, from 259 to 266, while the 2023 average reached 0–60 mph in 7.3 seconds.
Average new-vehicle footprint was 51.8 square feet in 2023. Footprint means the area defined by wheelbase and track width, not interior cargo volume, and EPA’s preliminary projection for model year 2024 was 51.6 square feet.
Large SUV Electrification and Powertrain Adoption
Electrification is clearest in EPA’s car-SUV category, which includes many smaller crossovers and is therefore not a direct measure of electric large-SUV adoption. In model year 2023, battery-electric vehicles represented 36% of car-SUV production.
| Car-SUV measure | Model year 2023 | Preliminary model year 2024 |
|---|---|---|
| Production share | 12.5% | 15.4% |
| Average real-world fuel economy | 40.5 mpg | 40.3 mpg |
| Average real-world CO2 | 190 g/mi | — |

Car-SUV production share increased from 10.4% in 2022 to 12.5% in 2023. EPA’s preliminary 2024 projection was 15.4% of production, with preliminary average fuel economy of 40.3 mpg; both 2024 figures are forecasts rather than final observed data.
For truck SUVs, EPA’s preliminary 2024 projection was 46.6% of production and 26.0 mpg average real-world fuel economy. The projection does not establish how many large SUVs were electric, hybrid, or combustion-powered.
The 2024 EPA guide also excludes SUVs above 10,000 pounds GVWR from light-duty fuel-economy regulations. This is a reporting and regulatory boundary, not a claim that all large SUVs exceed it; Fuel Economy Guide 2024 explains the rating limits and class definitions.
Large SUV Safety and Fatality Statistics
IIHS reports size-specific fatality rates for vehicles that were 1–3 years old in 2024. The rates are deaths per million registered vehicles and reflect vehicle design, use patterns, exposure, and driver demographics; they are not probabilities for an individual trip.
| IIHS SUV category and crash setting | Driver deaths per million registered vehicles, 2024 |
|---|---|
| Large SUV, all crashes | 12 |
| Large SUV, multiple-vehicle crashes | 7 |
| Large SUV, single-vehicle crashes | 4 |
| Large SUV, single-vehicle rollover crashes | 3 |
| Very large SUV, all crashes | 22 |
| All SUVs, all crashes | 27 |

In the same IIHS table, large SUVs had 19 driver deaths in all crashes, including the rate of 12 per million registered vehicles. They had 12 driver deaths in multiple-vehicle crashes and 7 in single-vehicle crashes, corresponding to rates of 7 and 4 per million.
Very large SUVs recorded 22 driver deaths per million registered vehicles in all crashes, while all SUV sizes combined recorded 27 per million. The categories are not interchangeable: IIHS separates large and very large SUVs, while “all SUVs” also includes small and midsize vehicles.
SUV occupants accounted for 6,648 passenger-vehicle occupant deaths in 2024, or 29% of the total shown by IIHS. That broad count includes small, midsize, large, and very large SUVs and should not be interpreted as a large-SUV-only total.
Large SUV Rollover and Crash-Outcome Statistics
IIHS recorded 2,200 SUV occupant deaths in rollover crashes in 2024. Its rollover definition is a vehicle tipping onto its side or roof at any time, and the statistics cover all SUV sizes rather than large SUVs alone.
| Initial impact before rollover | Share of SUV rollover occupant deaths, 2024 |
|---|---|
| Frontal | 45% |
| Side | 16% |
| Rear | 5% |
| No recorded initial impact | 25% |
Source: Fatality Facts 2024: Passenger vehicle occupants.
Rollover crashes accounted for 22% of SUV occupant deaths in 2024. For passenger vehicles overall, rollover was involved in 28% of occupant deaths; the share was 47% in single-vehicle occupant deaths and 13% in multiple-vehicle occupant deaths.
The impact breakdown describes the initial impact point, not necessarily the complete crash sequence. Among SUV occupant deaths in 2024, 73% were drivers and 26% were passengers; the percentages may not total 100% because of rounding and unknown categories.
IIHS also reported 232 driver deaths in SUV multiple-vehicle frontal impacts, a rate of 10 per million registered vehicles in the 1–3-year-old exposure frame. This is an all-SUV measure, not a large-SUV-only outcome.
