Lightweight and intelligent vehicles have become a new trend in the development of the global automotive industry.
In recent years, with the pressure and development trend of global energy saving and emission reduction,
Countries have formulated strict passenger car fuel consumption standards and regulations,
Regarding passenger car fuel consumption and corresponding CO2 emissions,
Lightweight puts forward more stringent requirements.
Automobile is also the development trend of world automobile.
Especially in China, the decline in vehicle fuel consumption by 2021, will be significantly greater than in other countries, and the pressure on fuel emissions will be greater. Reducing the weight of the entire vehicle is the most effective way to reduce the weight of the vehicle.
Car lightweighting is to “slim down” the car. On the basis of ensuring the stability and improvement of performance, energy-saving design of all parts and components, and continuous optimization of models.
Experiments have proved that if the weight of the vehicle is reduced by 10%,
The fuel efficiency can be increased by 6%-8%;
The vehicle weight can be reduced by 1%, and the fuel consumption can be reduced by 0.7%;
For every 100 kg reduction in the vehicle’s curb weight, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters.
