What is engine power called?

Engine power is commonly referred to as "horsepower" or "kilowatts"—key metrics for measuring an engine's output. Horsepower (hp) is an imperial unit, while kilowatts (kW) belong to the metric system. The two can be converted using a simple formula: 1 horsepower equals roughly 0.746 kilowatts. But power isn’t the only factor—torque plays a huge role in performance too. It determines a vehicle’s acceleration and load-carrying capability, which comes into play when overtaking or climbing hills. In real-world driving, the combination of power and torque shapes the overall experience. High horsepower suits speed-focused drivers, while high torque is better for heavy loads or mountainous terrain. Other factors like engine tuning, intake and exhaust systems also affect power output. Different brands leverage unique technologies—turbocharged and naturally aspirated engines, for example, each have their strengths. Understanding these specs helps you pick a car that matches your driving needs.
