What kinds of automobile performance indicators are there?

1, power

It refers to the maximum speed of the car can overcome the maximum gradient and acceleration ability. The main evaluation indexes are: maximum speed, acceleration time and drums to climb the slope. When the maximum speed of the car decreases, acceleration time or acceleration distance increases, traction is reduced. Indicates that the automobile power has declined.

2, economy

The fuel and oil consumed by the engine and the engine running at a certain speed of motorcycle hours ratio. In terms of the whole car, if a certain machine parts (such as tires) wear fast . Repair costs increase and the cost of running the car increases . This also indicates a decrease in the economy of the car.

3, reliability

It refers to the automotive products (assemblies or components) in the specified 'conditions and the specified time to complete the specified function of the ability. Automobile in the operation of the failure (such as oil leakage, water leakage, heat, abnormal noise, etc.) increased, the number of stops for maintenance increased, driving safety is not guaranteed, are indicative of the decline in the reliability of automobile driving.

Other accident prevention factors

Acceleration, driving posture, vision, and even seat comfort can affect the safety performance of a car. A car that accelerates quickly can make it easy for a driver to escape a potential accident zone. Driving position affects vision and comfort. The better the field of vision, the earlier the signs of an accident can be detected. The seat also plays a role, albeit a small one. Being uncomfortable in the seat can cause fatigue and affect the driver's alertness.

If a collision occurs, a vehicle's ability to protect its occupants becomes critical. The U.S. government's Highway Traffic Safety Commission's testing focuses on this ability of a vehicle.
