Performance cars combine measurable output with engineering choices that affect how a car feels on the road. These statistics compare selected model-year 2024 performance-oriented passenger-car configurations using horsepower, engine displacement, cylinder count, transmission gears, and EPA combined fuel economy. They also place those model figures beside EPA fleet-level 0-to-60 benchmarks for model years 1978–2025.

Horsepower at a glance
The selected 2024 cars span a wide output range. The Toyota GR86 was rated at 228 horsepower, while the Chevrolet Corvette Z06 reached 670 horsepower. That is a 442-horsepower spread across the examples in this comparison, but the figures represent different vehicle concepts rather than a single standardized class.
According to the EPA Model Year 2024 Fuel Economy and Technology Data, the ratings were:
- Chevrolet Corvette Z06: 670 horsepower.
- Porsche 911 Turbo S: 640 horsepower.
- Audi RS 6 Avant: 621 horsepower.
- Porsche 911 GT3 RS: 518 horsepower.
- Ford Mustang Dark Horse: 486 horsepower.
- BMW M4 Coupe: 473 horsepower.
- Audi RS 3: 401 horsepower.
- Volkswagen Golf R: 315 horsepower.
- Hyundai Elantra N: 280 horsepower.
- Toyota GR86: 228 horsepower.
The Corvette Z06 was the highest-rated example in this set, at 670 horsepower. The 911 Turbo S followed at 640 horsepower, while the RS 6 Avant was rated at 621 horsepower. At the other end, the GR86 and Elantra N show that performance-oriented cars do not need the output of a large-displacement V8 to occupy this comparison.
Horsepower also needs context. The EPA data identifies the model-level values and matching configurations, but these cars should not be treated as members of one universal EPA-defined “performance car” category. The selection is performance-oriented, and the numbers are best read as a snapshot of representative model-year 2024 configurations.
Engine size and cylinder layout
Engine displacement ranges from 2.0 liters to 5.5 liters among the selected cars. The smallest engines in the set were the 2.0-liter units in the Volkswagen Golf R and Hyundai Elantra N. The largest was the Corvette Z06’s 5.5-liter engine, followed by the Ford Mustang Dark Horse at 5.0 liters.
The EPA CSV lists these displacements:
| Vehicle | Displacement | Cylinders |
|---|---|---|
| Porsche 911 GT3 RS | 4.0 L | 6 |
| Porsche 911 Turbo S | 3.745 L | 6 |
| BMW M4 Coupe | 3.0 L | 6 |
| Audi RS 3 | 2.5 L | 5 |
| Audi RS 6 Avant | 4.0 L | 8 |
| Ford Mustang Dark Horse | 5.0 L | 8 |
| Chevrolet Corvette Z06 | 5.5 L | 8 |
| Toyota GR86 | 2.4 L | 4 |
| Volkswagen Golf R | 2.0 L | 4 |
| Hyundai Elantra N | 2.0 L | 4 |
The cylinder counts range from four to eight. Four-cylinder engines appear in the GR86, Golf R, and Elantra N. The Audi RS 3 uses five cylinders. Six-cylinder engines power both Porsche examples and the BMW M4 Coupe. Eight-cylinder engines are used by the RS 6 Avant, Mustang Dark Horse, and Corvette Z06.
Displacement and cylinder count do not form a simple horsepower ranking in this sample. The 3.745-liter, six-cylinder 911 Turbo S was rated at 640 horsepower, while the 5.0-liter, eight-cylinder Mustang Dark Horse was rated at 486 horsepower. Conversely, the 5.5-liter, eight-cylinder Corvette Z06 produced the highest listed output at 670 horsepower. These comparisons describe the displayed specifications; they do not establish a general rule about how engine size determines performance.
Transmission gear counts
The selected transmissions range from six to ten speeds. The Ford Mustang Dark Horse automatic configuration used the largest count, with 10 speeds. The Porsche 911 Turbo S, Audi RS 6 Avant, and Chevrolet Corvette Z06 each used an 8-speed transmission. Several cars used 7-speed transmissions, while the manual configurations in the BMW M4 Coupe, Toyota GR86, and Hyundai Elantra N used 6-speed transmissions.
The configuration details in the EPA Model Year 2024 data are:
- Porsche 911 GT3 RS: 7-speed transmission.
- Porsche 911 Turbo S: 8-speed transmission.
- BMW M4 Coupe: 6-speed manual transmission.
- Audi RS 3: 7-speed transmission.
- Audi RS 6 Avant: 8-speed transmission.
- Ford Mustang Dark Horse: 10-speed transmission in the automatic configuration.
- Chevrolet Corvette Z06: 8-speed transmission.
- Toyota GR86: 6-speed transmission in the manual configuration.
- Volkswagen Golf R: 7-speed transmission in the automated-manual configuration.
- Hyundai Elantra N: 6-speed transmission in the manual configuration.
Gear count is therefore not interchangeable with transmission type. A 6-speed manual and a 6-speed automated or automatic design would represent different configurations, and the supplied model-level figures specifically identify manual, automated-manual, or automatic variants where applicable. The Mustang and GR86 figures in this section should be read with those configuration labels attached.
Combined fuel economy
EPA combined fuel economy for the selected gasoline vehicles ranges from 15 mpg to 25 mpg. The Chevrolet Corvette Z06 was rated at 15 mpg combined, while the Volkswagen Golf R automated-manual configuration was rated at 25 mpg combined. The 10-mpg spread shows that the performance-oriented group includes meaningful variation in everyday fuel-use ratings.
| Vehicle and configuration | EPA combined fuel economy |
|---|---|
| Chevrolet Corvette Z06 | 15 mpg |
| Porsche 911 GT3 RS | 16 mpg |
| Porsche 911 Turbo S | 16 mpg |
| Audi RS 6 Avant | 17 mpg |
| Ford Mustang Dark Horse, automatic | 17 mpg |
| BMW M4 Coupe | 19 mpg |
| Toyota GR86, manual | 22 mpg |
| Audi RS 3 | 23 mpg |
| Hyundai Elantra N, manual | 24 mpg |
| Volkswagen Golf R, automated-manual | 25 mpg |
The EPA ratings put the 911 GT3 RS and 911 Turbo S at 16 mpg combined. The RS 6 Avant and automatic Mustang Dark Horse were each rated at 17 mpg. The BMW M4 Coupe was rated at 19 mpg, followed by the manual GR86 at 22 mpg, the RS 3 at 23 mpg, and the manual Elantra N at 24 mpg.
These are EPA combined labels for gasoline vehicles, expressed in miles per gallon. They are not fuel-consumption measurements for every driver or every driving route. The configuration matters: the supplied figures identify the automatic Mustang, manual GR86, automated-manual Golf R, and manual Elantra N specifically.
How the cars compare
Looking across the four model-level measures gives a useful statistical profile of the group. The Corvette Z06 combines the highest horsepower and largest displacement in the selection with the lowest combined fuel-economy rating. The Golf R has the lowest listed displacement, at 2.0 liters, yet its 25 mpg combined rating is the highest among the examples.
The Porsche entries illustrate two different balances within one model family. The 911 GT3 RS used a 4.0-liter, 6-cylinder engine, produced 518 horsepower, used a 7-speed transmission, and was rated at 16 mpg combined. The 911 Turbo S used a 3.745-liter, 6-cylinder engine, produced 640 horsepower, used an 8-speed transmission, and was also rated at 16 mpg combined.
The four-cylinder cars occupy the lower end of the horsepower list but not the same place in fuel economy. The GR86 was rated at 228 horsepower and 22 mpg combined in its manual configuration. The Golf R was rated at 315 horsepower and 25 mpg combined in its automated-manual configuration. The Elantra N was rated at 280 horsepower and 24 mpg combined in its manual configuration.
The EPA model-level file contains multiple rows for some configurations when production volume or label variants differ. Each statement here uses the matching configuration and reports the displayed EPA value. These comparisons should therefore be treated as a selected model-year snapshot, not as an estimate of the entire performance-car market.
EPA acceleration benchmarks and long-run trends
EPA fleet statistics provide a broader context for 0-to-60 performance, but they are not manufacturer test claims for the individual cars above. In The 2025 EPA Automotive Trends Report: Fuel Economy, and Technology since 1975 (EPA-420-R-26-001), the EPA estimated the average new-vehicle 0-to-60 time at 7.5 seconds for model year 2024. The report projected a 7.3-second average for model year 2025.
The same report says the average new-vehicle 0-to-60 time was down 45% from model year 1978 for the all-vehicle fleet, covering model years 1978–2024. Within its vehicle groupings, the average sedan/wagon 0-to-60 time was down 43% from model year 1978, the average car-SUV time was down 46%, and the average pickup-truck time was down 50%.
| EPA fleet measure | Reported result | Period |
|---|---|---|
| Average new-vehicle 0-to-60 time | 7.5 seconds | Model year 2024 estimate |
| Average new-vehicle 0-to-60 time | 7.3 seconds | Model year 2025 projection |
| All-vehicle fleet change | 45% lower | Model years 1978–2024 |
| Sedan/wagon change | 43% lower | From model year 1978 |
| Car-SUV change | 46% lower | From model year 1978 |
| Pickup-truck change | 50% lower | From model year 1978 |
The report’s 7.5-second and 7.3-second figures are calculated or projected fleet benchmarks, so they should not be compared as if they were controlled manufacturer tests of the Porsche, BMW, Audi, Ford, Chevrolet, Toyota, Volkswagen, or Hyundai models listed above. The EPA also states that acceleration values for battery-electric, plug-in hybrid, and hybrid vehicles have greater uncertainty. The long-run percentages describe changes in average fleet categories, not the improvement of any one performance-car model.
