Car dynamics is defined as the study of the action of various car technologies and features on car body. It mainly includes technologies that help reduce fuel consumption and emissions.

Today, many car manufacturers are putting in the best of their efforts to introduce innovative technologies and measures to ensure efficient car dynamics. The introduction of alternative fuels, advanced engine technology, and innovative wheel types has helped many manufacturers to achieve improved efficiency and performance. Inspite of these, there are many such factors that prove to be magical when it comes to car dynamics.

Some of the aspects of a car that contributes to reduce fuel consumption as well as automotive emissions without any compromise on performance are: car weight, aerodynamic structure, automatic ignition system, and regenerative braking.

Car weight plays an important role in improving fuel efficiency as well as dynamics. It is truly believed that lighter the car more is the fuel efficiency. Reduction in actual car weight can be simply done by reducing the weight of the car components including the engine weight and the weight of the suspension. Once the weight is reduced, the engine has to put in less force to propel the car, eventually delivering better fuel efficiency and car dynamics. Some of the car manufacturers use aluminium, wherever possible, instead of steel in designing the car body structure. Aluminium is extensively replacing steel car bodies due to its light weight and thus improves energy efficiency of a car. It is used in the high speed and luxury cars in which light weight is priority to gain more engine efficiency. Steel is necessary to maintain the strength of the car body but in areas like roofs, doors, bumpers, and fenders, aluminium can be effectively used.
