51 Performance Car Statistics on Power, Efficiency, and Safety

Performance car statistics show how the U.S. new-vehicle fleet changed from 1975 through 2024: average horsepower reached 267 in the preliminary 2024 estimate, while efficiency, electrification, vehicle mix, and road-safety measures developed on different timelines. The figures below describe U.S. new light-duty vehicles unless a safety statistic is explicitly identified as covering all motor vehicles.

EPA production-weighted data show a long-term rise in the average power of new U.S. light-duty vehicles, with a temporary low point in the early 1980s. The 2024 value is preliminary, while model years 1975 through 2023 are final in the EPA report.

Measure Period Result
Average new-vehicle horsepower 1975 137 hp
Average new-vehicle horsepower 1981 102 hp
Average new-vehicle horsepower 2022 259 hp
Average new-vehicle horsepower 2023 266 hp
Average new-vehicle horsepower Preliminary 2024 267 hp

The EPA reports that average new-vehicle horsepower in 2023 was 94% higher than in 1975 and 160% higher than in 1981. These are production-weighted fleet measures, not the output of a narrowly defined performance-car class. 2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975

Power growth also differed by vehicle grouping. From 1975 to 2023, sedan and wagon horsepower increased 69%, while car-SUV horsepower increased 139% and pickup horsepower increased 141%, according to the same EPA analysis.

Performance Car Data: Acceleration, Weight, and Footprint

Acceleration improved alongside power, although the measure has important methodological limits. EPA 0-to-60 values are calculated for most vehicles and are uncertain for electric vehicles, hybrids, and plug-in hybrids.

Vehicle-performance measure Period Result
Average new-vehicle 0-to-60 time 2022 7.6 seconds
Projected average new-vehicle 0-to-60 time 2023 7.3 seconds
Truck-SUV 0-to-60 decline Since 1978 45%
Minivan/van 0-to-60 decline Since 1978 44%
Car-SUV 0-to-60 decline Since 1978 46%

Since 2004, average horsepower rose 23%, compared with a 5% increase in average weight. Since 2008, average vehicle footprint increased 6%, showing that the physical dimensions of the fleet changed along with its power and performance characteristics.

The upper end of the production range was also substantial: the maximum individual vehicle horsepower reported by the EPA was 1,600 horsepower, while 7% of vehicles were above 250 horsepower. Those figures describe the observed new-vehicle set rather than a sales-weighted definition of enthusiast performance cars. 2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975

Performance Car Statistics: Fuel Economy and CO2 Tradeoffs

Power and acceleration should be read alongside fuel economy and emissions. For U.S. new light-duty vehicles, the EPA reported 27.1 mpg average fuel economy and 319 g/mi average carbon-dioxide emissions in 2023.

Measure Period Result
Average fuel economy 2023 27.1 mpg
Average CO2 emissions 2023 319 g/mi
Fuel-economy change from prior year 2022–2023 +1.1%
CO2 change from prior year 2022–2023 -18 g/mi
Gasoline ICE without stop/start CO2 2022–2023 dataset 422 g/mi
Gasoline ICE with stop/start CO2 2022–2023 dataset 357 g/mi

The EPA’s reported CO2 decline versus 2022 was 18 g/mi, while fuel economy increased 1.1%. The gasoline internal-combustion comparison shows the role of stop/start technology: the reported value was 422 g/mi without the system and 357 g/mi with it.

Gasoline internal-combustion vehicles without stop/start recorded 24.1 mpg in the supplied comparison, and gasoline fuel consumption per unit of engine displacement declined 11% over the relevant 2022–2023 comparison. These figures are technology and fleet measures, not direct operating-cost estimates for a particular performance model. 2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975

Vehicle-Type and Market-Mix Statistics

The production mix matters because fleet averages combine cars, SUVs, pickups, vans, and other light-duty vehicles. For model-year 2024 U.S. production, cars accounted for 34% and trucks for 66%, with truck-SUVs alone representing 50%.

Model-year 2024 production measure Share
Cars 34%
Trucks 66%
Truck-SUVs 50%
Vehicles reaching 400 horsepower in 2023 7%

The average number of cylinders across all production was 4.9, while the gasoline internal-combustion group without stop/start averaged 6 cylinders. The EPA also reported a diesel production peak of 6% and a 4.9% increase in diesel specific power.

One supplied production-share entry reports gasoline internal-combustion vehicles without stop/start at 250%. Because a production share cannot exceed 100%, that figure is retained here as reported but should be treated as a source-label or transcription issue rather than interpreted as a literal market share. 2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975

The supplied EPA technology figures use model-year 2023 production, with related calendar-year coverage from 2020 through 2024. They describe production shares, not calendar-year sales shares.

Powertrain or drivetrain measure Period Production share
Gasoline ICE with stop/start Model year 2023 26.3%
Mild hybrid Model year 2023 49.2%
Strong hybrid Model year 2023 4.9%
Plug-in hybrid Model year 2023 7.2%
Battery electric vehicle Model year 2023 1.7%
Diesel Model year 2023 9.8%
Turbocharged Model year 2023 0.8%
CVT-equipped Model year 2023 56.4%

The largest listed technology share was mild-hybrid production at 49.2%, followed by continuously variable transmission production at 56.4% when the measures are considered separately. The categories should not be added together because they describe overlapping technology dimensions rather than mutually exclusive groups.

The battery-electric production share was 1.7%, while plug-in hybrids reached 7.2% and strong hybrids 4.9% in the model-year 2023 figures. These production measures help describe technology adoption, but they do not establish performance outcomes for every vehicle type. 2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975

Engine Technology and Road-Safety Outcomes

Road-safety statistics provide context for performance discussions, but the NHTSA figures below cover all motor vehicles, not performance cars specifically. They therefore cannot be used to attribute a national fatality result to horsepower, a particular engine, or a particular vehicle segment.

NHTSA reported that speeding was associated with 24.4% of traffic fatalities in 2020 and 49.2% in 2021. The supplied NHTSA measure also reports a 90% speeding-fatality increase over that comparison and estimates that speeding represented 200% of fatalities in 2021; because the latter exceeds a conventional share, it should be read as reported rather than reconciled into a new calculation. NHTSA, Speeding and Speed Management

The broader safety series includes an estimated 6% change in first-half 2024 traffic fatalities and 12 consecutive quarters of declining fatalities. The first-half 2024 figure is an estimate, and both measures concern nationwide traffic safety rather than the ownership, use, or outcomes of performance cars. NHTSA, 2024 Early Estimates of Decreased Traffic Fatalities

Across these sections, the central measurement distinction is consistent: EPA figures describe U.S. new light-duty-vehicle production, technology, power, efficiency, and calculated acceleration, while NHTSA figures describe all-motor-vehicle safety outcomes. EPA model years 1975–2023 are final, 2024 values are preliminary projections, and EPA acceleration estimates are uncertain for EVs, hybrids, and plug-in hybrids.
