Methods to improve the cycle include the two methods below. 

The first is the productivity cycle. 
The establishment of a versatile automobile platform allows for changes in design, such as in the front, back, fender, and roof while also making it possible to ship vehicles in a way that corresponds to the sales strategy and designs for each reason. 
This will significantly contribute to economic efficiency and CO2 reduction. 

The second is the raw materials cycle. 
The body and platform are produced using highly recyclable materials such as aluminum, ABS, and PC. 
In addition, manufacture and removal of complicated parts such as lights, fenders, or the motor are simplified through implementing modular design. 
This will improve productivity and make separation of recyclable materials easier upon disassembly. 
The change and repair of parts can also be done at low cost and with minimal negative effects on the environment. 
In addition, an improvement in the efficiency of part changes will respond to each user’s demands for customization, which will promote vehicle use over the long term. 


This efficiency in customization is at the heart of the Renault 4. 
Components made modular and a response to each strategy. 
The new Renault achieves a cycle that is both economically and environmentally friendly.
