What are the main performance indicators of a car?

Car's main performance indicators are as follows: Power performance of the car: The main parameters of power performance include maximum speed, 0-100 km/h acceleration time, and climbing ability. The higher the maximum speed, the shorter the 0-100 km/h acceleration time, and the greater the fully loaded climbing angle, the better the car's power performance. Fuel economy: This refers to fuel consumption. Among competing models in the same category, the better the car's fuel economy, the lower the fuel consumption. Of course, fuel consumption is also greatly influenced by driving conditions and the owner's driving habits, but the car's inherent fuel economy plays a dominant role. Braking performance of the car: The main reference parameters include 100 km/h braking distance, braking efficiency consistency, 100 km/h braking time, and braking stability. The shorter the 100 km/h braking distance and time, and the less noticeable the body offset or skid, the better the braking performance.
As an ordinary car owner who drives daily, the main performance indicators in my eyes are fuel efficiency and power performance, as these directly impact both my wallet and driving experience. Low fuel consumption means fewer trips to the gas station, saving money amid fluctuating oil prices; good power performance is reflected in quick acceleration, such as rapid engine response when overtaking on national highways without any lag. Comfort is also crucial—soft suspension that doesn’t jolt and minimal cabin noise make long-distance drives less tiring. Safety-wise, ABS systems and short braking distances help avoid accidents. High reliability with fewer breakdowns is a plus, and don’t forget about smooth transmission—excessive shuddering is always annoying. These everyday indicators combined determine the happiness of car ownership and are worth prioritizing when choosing a vehicle.
From years of repair experience, performance indicators are not just superficial aspects; the core lies in engine output and the transmission system. The horsepower and torque of the engine determine the starting and climbing ability—too low, and it struggles when towing. The smoothness of the gearbox matching, without jerking, affects driving fluidity. The efficiency of the braking system, such as the wear level of the brake discs, relates to shorter stopping distances for safety. The rigidity of the suspension and the grip of the tires control handling stability. The electrical system, including battery lifespan and failure rates, is also a crucial reference to avoid frequent time-consuming repairs. These details build the vehicle's durability and overall performance. When choosing a car, actual test data is more practical than promotional claims.
Safety is my top priority when choosing a car, with performance indicators including crash test scores and active assistance features. A sturdy body structure protects passengers in accidents, such as high Euro NCAP ratings; shorter braking distances reduce reaction time during emergency avoidance. Handling stability prevents steering loss of control, while the ABS system reduces skidding risks. Anti-lock devices and side airbags elevate the safety level. These indicators, combined with daily maintenance habits like regular tire pressure checks, enhance driving confidence and defensive capabilities.
