Stop asking how much horsepower a vehicle has. The industry is shifting, and the new benchmark is kilowatts. If you see an EV spec sheet, the number next to “kW” tells you exactly how much work that motor can do per second. It is the modern equivalent of the horsepower question you used to yell at passing sedans.
Why the shift from horsepower to kilowatts?
James Watt invented the term horsepower in the 1700s. He calculated that one horse could perform 33,000 foot-pounds of work in a minute, essentially moving 1,000 pounds of coal 33 feet in that time. A 300-horsepower gasoline engine does the work of 300 of those horses simultaneously. Most countries still use this metric for internal combustion engines, though Australia prefers kilowatts even for gas cars.
Watt also gave us the watt and the kilowatt. These measure electrical power. A kilowatt is simply 1,000 watts. When Nissan describes the upcoming LEAF electric vehicle, they specify an 80 kW AC synchronous motor.
That “AC” designation matters. It means the motor runs on alternating current. This setup allows the car to recharge its battery pack through regenerative braking. It is not the battery driving the wheels; the 24 kilowatt-hour battery pack just supplies the energy to the motor. That motor is mechanically simpler and more efficient than any internal combustion engine you have ever owned.
How much horsepower is 80 kilowatts?
To compare electric output to the old standard, you need a conversion factor. Multiply the kilowatt figure by 1.34.
80 kW x 1.34 = 107.2 horsepower.
So, the LEAF’s 80 kW motor is roughly equivalent to 107 horsepower.
Is 107 horsepower enough?
On paper, 107 horsepower sounds modest for a five-door, five-passenger hatchback. A similarly sized Nissan Versa produces roughly the same amount of power. But gas engines and electric motors do not deliver power the same way.
An electric motor has a flat torque curve. It delivers peak torque instantly and maintains constant power output across a wide range of speeds. A gas engine needs to spin up to hit its power band. Because of that instant availability, the LEAF promises brisk acceleration around town despite the lower headline number. The numbers do not tell the whole story. The feel is different, faster, and more immediate.
