The Ferrari LaFerrari has a combined output of 950 horsepower. This figure is the commonly quoted mechanical-horsepower equivalent of the car’s 963 PS total system output.
LaFerrari combines a naturally aspirated 6.3-liter V12 with Ferrari’s HY-KERS hybrid system. The V12 produces 800 PS, while the electric assistance contributes an additional 163 PS, giving a combined maximum of 963 PS, or approximately 950 hp.
The distinction between hp and PS explains why reputable sources may show either 950 hp or 963 PS. They describe the same peak system output using different horsepower standards; the figures should not be treated as competing specifications.
Introduced in 2013, LaFerrari was Ferrari’s first production hybrid road car and the successor to the Enzo. Its hybrid system was derived from Ferrari’s Formula 1 energy-recovery expertise, adding acceleration performance while also improving efficiency.
