What is the power output of a family sedan?

Family cars typically have around 100kw. Automobile power: 1 horsepower equals 0.735 kilowatts. Power is a physical quantity that indicates how fast an object does work. In physics, power P = work W / time t, and the unit is watt (w). The greater the power, the greater the torque, and the higher the pulling force of the car. Maximum power is commonly used to describe the dynamic performance of a car. Automobile power: Power refers to the work done by an object per unit time, meaning power is a physical quantity that indicates the speed of doing work. The greater the power, the higher the rotational speed, and the higher the maximum speed of the car. Maximum power is commonly used to describe the dynamic performance of a car. Maximum power is usually expressed in horsepower (PS) or kilowatts (kw), with 1 horsepower equaling 0.735 kilowatts.
I usually drive the family's old Nissan Sylphy, which has a power output of around 100 horsepower, or about 70-80 kilowatts when converted. This power level is more than sufficient for city commuting. During rush hour traffic jams, even higher power wouldn't make much difference. Overtaking on highways might feel a bit sluggish, but the fuel efficiency is truly impressive, saving quite a bit on monthly fuel costs. Nowadays, many new models have significantly higher power outputs, like 1.5T engines that typically deliver around 130 kilowatts. However, I believe for average family cars, a power range between 80 to 120 kilowatts offers the best balance—enough power for daily use without being too fuel-thirsty. If you frequently travel long distances with a full load, it's advisable to opt for a higher power output.
A couple of days ago, I compared some data while helping a friend check out cars, and the power range of current family sedans is actually quite wide. Entry-level models like the Fit only have about 80 kW with their 1.5L naturally aspirated engines. Mainstream compact cars such as the Corolla and Civic range from 90 to 130 kW. Mid-size sedans like the Camry with a 2.5L engine can reach around 150 kW. Electric vehicles are different—the Model 3 with a single motor already exceeds 200 kW. Power mainly affects acceleration and high-speed performance, but in city driving, the difference isn't that noticeable. When choosing a car, don't just focus on the power specs; the vehicle's weight and transmission matching are more important. Some high-power cars with heavy bodies might actually feel sluggish in real-world driving.
Remember cars from ten years ago, where a 2.0-liter engine typically had less than 120 horsepower. Nowadays, the same displacement usually starts at 150 horsepower. Technological advancements have significantly increased power output, especially with the widespread adoption of turbocharging. However, real-world driving experience can't be judged by paper specs alone. I've driven a car with 130 kW that felt more sluggish in throttle response than an older model with just 100 kW. The key lies in electronic system tuning. Modern engines with high thermal efficiency deliver both power and fuel economy. Even small-displacement engines can achieve decent power levels with turbocharging—for example, a 1.0T can reach around 90 kW.
