Abstract
Car lightweight is an important means to achieve energy-saving emission reduction and methods, in improving the fuel economy and environmental protection has an important role. At present, the lightweight new material is the main way of the current body weight reduction, through the multi-material structure optimization, both to improve vehicle performance, but also significantly reduce the quality. This chapter discusses the performance and application of several lightweight materials, describes the development of lightweight materials in the automotive industry and the application of the trend
Key words: automotive ;lightweight ;lightweight materials

The study of lightweight car is a mainstream of modern car design and manufacturing. Car lightweight, is to ensure the strength and safety of the car under the premise of the car as much as possible to reduce the quality of the preparation, thereby enhancing the vehicle's power, reduce fuel consumption and reduce exhaust pollution. Data show that if the car to reduce the quality of 10%, fuel efficiency can be increased by 6% to 8%, fuel consumption can be reduced by 6% to 10%. Fuel consumption decline, emissions also decreased, while resource utilization increased, extended life of the car, the use of performance has improved significantly. Car body quality accounts for about 50% of the quality of the vehicle, it is clear that the lightweight body for the vehicle lightweight play a pivotal role [1]. At present, the car body weight reduction has two main research directions: First, the use of lightweight materials; Second, optimize the structure. Structural optimization potential space has been very small, the gradual use of lightweight new materials is the current body of one of the main means of lightweight.
