The impact of lightweight on fuel efficiency is significant, as the weight of a vehicle directly affects its fuel consumption while driving. Here are some key takeaways and strategies that illustrate how lightweighting can improve fuel efficiency:
Weight vs. fuel consumption: The reduction in the weight of the vehicle reduces driving resistance, which in turn reduces fuel consumption. Experimental data shows that for every 10% reduction in vehicle weight, fuel efficiency can be improved by 6%-8%. Experimental data from British laboratories show that for every 30% reduction in vehicle weight, fuel efficiency can be improved by 20%-24%, while carbon dioxide emissions can be reduced by 20%.
Application of lightweight materials: The use of lightweight materials such as aluminum alloy, magnesium alloy, carbon fiber composite materials and other alternative to traditional steel can effectively reduce the weight of the vehicle. For example, for every 100 kg of weight lost in a car, fuel consumption can be reduced by 03-0.6 liters.
Optimize the design: Lightweighting can also be achieved by optimizing the vehicle design, such as improving aerodynamics and reducing unnecessary trim and accessories, which in turn improves fuel efficiency.
Lightweight powertrainLightweight engines and powertrains, such as lightweight materials and optimized design, can reduce the weight of the engine and powertrain and improve fuel economy.

Balance between weight reduction and performance: In pursuit of weight reduction, it is necessary to ensure that the safety, comfort, and performance of the vehicle are not compromised. This may require innovation in material selection, structural design, and manufacturing processes.
Policies and standards: Focus on national and regional fuel efficiency standards and lightweighting policies that may drive automakers to adopt more advanced lightweighting technologies and materials.
