The goal of this project was to produce conceptual design of a sustainable car for the year 2020. It is in continuation of the C,MM,N project started in 2006 by the 3TU and the Nature and environment to develop a ‘car of the future’. I set out with the conviction that, for a car to be meaningful people ought to use it. In 2020 the car will become part of a mobility service and money will be made over the lifetime of the car as it serves through several iterations of use. The service offers a vehicle tailored to the occasion, therefore the utilitarian aspects of the car become less important. The focus of society shifts from the quantative to the qualitative aspects of life. No longer do we measure the quality of our lives by our material possessions, but by our experiences. Therefore; “I want people to enjoy the sensation of motion, free from worries.” To achieve this, driver and the car should become one, providing the optimal sensation of motion. Networks provide all necessary travel information, enabling the driver to focus on driving. A social network is implemented in order for people to cooperate and fall back on in moments of need. By improving ‘visibility’ of the driver and giving insight into his actions on road interaction is made more personal and natural. The c,mm,n car incorporates three types of playto help us cope with the increasing difficulties of mobility and find creative solutions for our mobility problems. Bodily play, is incorporated in the c,mm,n in its ability to lean into corners, increasing the sensation of motion. On the other hand giving other road users insight into his actions and improving on road communication. Object play, is one of the great joys of driving; the mastery of the car. However the c,mm,n also stimulates the driver to master a fluid driving style in order to keep energy usage to a minimum. Social play, is an integral aspect of the c,mm,n as cooperation is key to optimal personal mobility. This is incorporated in various forms, which stimulate on road cooperation, focusing on communication, stimulating helping others and drafting. On the same time we should keep in mind that we have to work within the limits of the future, providing a car that is efficient enough to offer a decent range, a package providing for daily activities, while keeping size and weight to a minimum. The car is equipped with Michelin Active Wheels, which house electric drive, braking and active suspension, which enables leaning into corners. The car seats 4 persons, placed on top of two interchangeable 20kWh Lithium ion batteries. The passengers and batteries are placed within an extremely strong, low weight Carbon Fiber Reinforced Plastic safety cell. Further safety is provided by aluminum crash structure in the front and rear. Optimal aerodynamics are achieved by minimizing the frontal area and featuring a Kammback design, a back end tapered to approximately 50% of the maximum cross section.
