lightweight

The concept of being lightweight originated in motor sports, and its advantages are not difficult to understand. Lighter weight leads to better handling, and the power output of the engine leads to higher acceleration. Because the vehicle is light, the acceleration is better at the start.

As "energy conservation and environmental protection" has become a widely concerned topic, lightweight has also been widely used in the field of ordinary cars, which can improve the handling while also having excellent performance in fuel saving. Car's fuel consumption mainly depends on the engine displacement and the total mass of the vehicle, while maintaining overall car quality, performance and cost under the premise of unchanged even optimization, reduce vehicle weight can improve the output power, reduce noise, improve handling, reliability, increase speed and reduce fuel consumption, reduce emissions and improve security. According to some research figures, if the vehicle weight is reduced by 10%, the fuel efficiency can be improved by 6%-8%. If rolling resistance is reduced by 10%, fuel efficiency can be improved by 3%. If the transmission efficiency of the axle, transmission and other devices is increased by 10%, the fuel efficiency can be improved by 7%. The automobile body accounts for about 30% of the total mass of the automobile. In the case of no load, about 70% of the fuel consumption is used in the body mass. Therefore, the lighter body is of great benefit to the fuel economy, vehicle control stability and collision safety of the vehicle.

Main guiding ideology: On the basis of ensuring stable performance improvement, energy-saving design of each assembly parts, and continue to optimize the car profile.

The lightweight of a car is to reduce the vehicle's preparation quality as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve its power performance, reduce fuel consumption and reduce exhaust pollution. Experiments show that if the vehicle weight is reduced by 10%, fuel efficiency can be improved by 6%-8%. For every 100kg reduction of vehicle reconditioning mass, the fuel consumption of 100km can be reduced by 0.3-0.6 l; A 1% reduction in vehicle weight reduces fuel consumption by 0.7%. At present, due to the need of environmental protection and energy saving, the lightweight of automobile has become the trend of automobile development in the world.
