smart has always been a pioneer in matters of urban mobility and with the smart fortwo electric drive the company is showing the direction of development in cities around the world. Together with BASF, the largest automotive supplier in the chemical industry, smart is demonstrating its leading role in the use of forward-looking technologies above and beyond the drive system. The joint concept vehicle smart forvision presented at the 2011 International Motor Show in Frankfurt combines a futuristic design with technologies relating to energy efficiency, lightweight design and temperature management.

“With the forvision smart is doing justice to its role as Daimler’s think tank for urban mobility. We are presenting numerous world premieres that make uncompromising electric mobility possible. With the clear objective of greatly increasing the zero-emission range we concerned ourselves with all factors that influence this on the vehicle. This resulted in completely new concepts and materials in the areas of insulation, reflection, lightweight design and energy management. In addition to transparent organic solar cells, transparent and energy-saving light-emitting diodes and infrared-reflective films and coatings, high-performance foams are used for insulation against cold and heat.
smart is also setting new standards of lightweight design with the use of the first all-plastic wheels,” says Dr. Annette Winkler, Head of smart. “In conjunction with smart’s revolutionary DNA, we have designed a vehicle that is so unique that we can’t wait to take it out of the research laboratory and onto the roads!”
Daimler AG and BASF SE have developed a new concept vehicle that combines both companies’ ideas for holistic electric mobility. The two companies have combined their technological competencies for the first time, developing a futuristic vehicle concept that offers decisive solutions to the challenges of the future. The new vehicle brings design, lifestyle and technology together to form a new functional whole.
“Cars of the future need materials and technologies which reduce energy consumption whilst also increasing the range and level of comfort. Our innovations make a decisive contribution to this”, says Dr. Christian Fischer, Head of BASF Polymer Research. “We are proud to have developed a holistic concept for sustainable urban mobility in cooperation with smart. Together we are presenting a pioneering vehicle which is without parallel.”
Thanks to the combination of smart’s automotive expertise and BASF’s material and system competence a vehicle has been created which showcases technologies for sustainable and holistic electric mobility of the future. The researchers and designers intentionally realised a mixture of visionary materials and technologies in the concept vehicle – some of these are still at a laboratory stage while others have a realistic chance of entering series production.
Energy efficiency: light and energy from above
The hexagonal transparent areas on the roof of the smart forvision are an eye-catching feature – as the first light-transmitting roof that also generates energy. Transparent solar cells covering the entire roof surface are the technology used here. They are based on organic dyes embedded in a sandwich roof. The transparent dyes of the solar cells are light-activated. Even in diffused light and poor light conditions they generate enough energy to power the multimedia components and the three fans that assist with climate management in the vehicle interior. If the vehicle is standing in the sun the ventilation is permanently operated with the help of these solar cells, keeping the car cool. This new photovoltaic technology opens up further efficiency potential and the energy generated can be used for further applications in the car.
There is an additional new feature under the solar cells: transparent OLEDs (organic light-emitting diodes) illuminate the vehicle interior when the door is opened or a button pressed. When switched off they allow for a clear view outside. This results in a glass roof effect during the daytime , whilst the areas are pleasantly illuminated without any dazzle at night. Thanks to a free choice of colours the new OLEDs do not only offer more design freedom, they also consume less than half as much energy as conventional energy-saving lamps.
