The combined horsepower of the 2023 Toyota Prius Prime is 220 hp.
The fifth-generation Prius Prime pairs a 2.0-liter four-cylinder gasoline engine with an electric motor and a 13.6-kWh lithium-ion battery. Toyota’s combined system output is 164 kW, commonly reported in the United States as 220 horsepower.
The figure represents the hybrid system’s combined output, not simply the gasoline engine’s rating. It is also easy to confuse the Prime with the regular 2023 Prius, whose output is lower, or with the European model’s 220-hp specification, which helped make that number especially prominent in launch coverage.
The 2023 Prius Prime also brought a major performance increase over the previous plug-in Prius. Toyota offered SE, XSE, and XSE Premium trims in North America, with EPA electric ranges of 44 miles for the SE and 39 miles for the XSE versions.
