Car horsepower over time: average and record power by decade
How much power new car generations made, decade by decade: the median, the average and the record holder. Figures come from the 1CARS catalog, which leans towards sports cars and American V8s, so read them as the catalog, not the market.
Key findings
- The median new car generation of the 2020s makes 282 kW (383 PS) in its most powerful version, against 89 kW (121 PS) in the 1920s.
- The 2020s record is the Lotus Evija with 1,500 kW (2,039 PS).
- The 2020s average (371 kW) is well above the median: a few hypercars pull the mean up, so the median is the better figure for a typical car.
- The median dipped to 67 kW in the 1940s before rising again.

Methodology
For each generation we take its most powerful version (peak power in kW from the generation record or its modifications) and group generations by the year production started. Median = the middle value; average = the mean; record = the highest value. Values below 5 kW or above 1,500 kW are treated as errors and excluded. 1 kW = 1.36 PS.
Passenger cars only: trucks, buses and vans are excluded (the same rule as our rankings).
Decades with fewer than 8 generations are not shown; the table gives the number of generations behind every figure.
Values come from the 1CARS catalog. Part of the specifications are extracted from our articles and not yet checked by an editor; obvious outliers are excluded. Figures describe the cars in our catalog, not the whole market.
