How is engine power measured?

There are two standard ways to measure engine power, typically using horsepower or kilowatts as units—these can be converted via a simple formula. Testing is usually done in a lab with a dynamometer, which simulates different loads and RPMs to record max power output and torque. Power reflects the engine’s overall performance, while torque determines acceleration and towing capability. It’s worth noting that engine power is divided into rated power (manufacturer’s ideal-condition claim) and real wheel power (actual output at the wheels, slightly lower due to drivetrain loss). Modern turbocharging and hybrid tech also allow smaller engines to deliver higher power without sacrificing fuel efficiency.
