What Car Parameters Should You Focus on When Buying a Car?

Buysing a car is a significant decision, with numerous models to choose from in the market. Understanding key car parameters can help consumers make a more suitable selection. The following car parameters are worth focusing on when buying a car.

In terms of power performance, engine parameters are core. Engine maximum power and maximum torque directly impact the vehicle's power performance. Maximum power is usually measured in kilowatts (kW) and determines the vehicle's top speed. Maximum torque is measured in Newton-meters (N·m) and represents the vehicle's acceleration ability. For example, turbocharged engines can output a large amount of torque at low speeds, making the car accelerate more rapidly. Generally, family cars have an engine maximum power of 100-200 kW and maximum torque of 200-400 N·m.

Fuel economy is also an important consideration. The National Bureau of Statistics' comprehensive fuel consumption is a reference indicator, which is obtained through testing under specific conditions. Actual fuel consumption will be affected by driving style, road conditions, etc. New energy cars need to focus on battery life, pure electric cars generally having a range of 300-600 kilometers, while plug-in hybrid cars have a pure electric range of 50-100 kilometers.

The vehicle's spatial dimensions include the length, width, height, and wheelbase. Vehicle length affects parking convenience, width determines the lateral space inside the car, and wheelbase refers to the distance between the front and rear axles, affecting interior passenger space, especially rear legroom space. Generally, compact cars have a wheelbase of 2.6-2.7 meters, while mid-range cars have a wheelbase of 2.7-2.9 meters.

Vehicle safety configuration parameters should not be overlooked. The number of airbags is an important indicator of passive safety, with common features including driver and passenger airbags, front and rear side airbags, and head-curtain airbags. Active safety configurations such as anti-lock braking systems (ABS) and electronic stability programs (ESP) can effectively prevent accidents from occurring. Some high-end cars also come equipped with advanced safety systems such as adaptive cruise control, automatic emergency braking, etc.

To make it easier to compare different car models' parameters, the following table provides a simple comparison:

When buying a car, consumers should consider their own needs and budget, taking into account these key parameters, to select the most suitable car for themselves.
