Material of brake pads

Do you know what material a car's brake pads are made of? In addition to traditional metal materials, some high-end cars use brake pads made of carbon fiber materials. The high strength and low weight of carbon fiber material make it one of the ideal materials for brake pads.

Fuel efficiency of automobiles

The fuel efficiency of a car may vary greatly under different driving conditions. For example, if you drive on a highway, the fuel efficiency of a car is usually higher than driving on urban roads. This is because when driving on highways, the car's engine can run more efficiently.

Car wipers

Do you know why car wipers have different speeds? This is because when driving at high speeds, if the wiper is too slow, it will affect the driver's field of view, while if the wiper is too fast, it will cause water splashes on the windows, which will also affect the driver's field of view.

Acceleration performance of automobiles

If you think sports cars have the best acceleration performance, then you may be wrong. In fact, some ordinary household cars may have better acceleration performance than some sports cars. This is because the acceleration performance not only depends on the engine performance of the car, but also is influenced by multiple factors such as vehicle weight, transmission system, and tire friction.

Distance traveled by one tank of oil

Do you know how far a car can travel? This depends on factors such as the fuel efficiency, fuel tank capacity, and driving conditions of the car. Generally speaking, a small sedan can travel about 500 to 700 kilometers after a single refueling operation.

Braking distance of automobiles

The braking distance refers to the distance required for a car to stop after braking. This depends on multiple factors, including vehicle speed, road conditions, and the quality of the braking system. Generally speaking, the distance required for a car to brake and stop at a speed of 80 kilometers per hour is more than 20 meters.

The proportion of manufacturing costs for automobiles

Automobiles are highly industrialized products with extremely high levels of mechanization and precision, which is also the reason why cars are more expensive. But usually its manufacturing cost only accounts for about 40% of the selling price, while other factors such as production costs, national taxes, and manufacturer profits account for about 60%.

Automobile tires

Do you know what the tire identification code means? For example, in P215/60R16, "P" represents the type of tire (P represents a passenger car tire), 215 represents the width of the tire (in millimeters), 60 represents the flat ratio of the tire (i.e. the ratio of tire height to tire width), R represents the structural type of the tire (R represents a rolled tire), and 16 represents the inner diameter of the tire (in inches).
