Optimally efficient energy use

While designing the aerodynamic shell of Stella Vie, a perfect balance between aerodynamic and aesthetic design was pursued. The result of this process yielded a car body which features some well known automotive design features whilst also being nine percent more aerodynamic than its predecessor, Stella Lux. Although Stella Vie has a smaller battery and a solar array that is one square meter smaller, it still achieves a range of a 1000 kilometers on a sunny summer day in the Netherlands. The surplus energy generated by Vie can be supplied back to the house or electric grid. The smart charging and discharging system keeps track of energy prices and the user’s agenda in order to find the optimal time to charge or discharge. Stella Vie’s charging status can also easily be checked through its connection with a smart thermostat.

Interior design

Efficient driving assistance

Through it’s updated solar navigator, which now takes height profile maps into account, Stella Vie finds the most efficient route and shows how much energy you will save compared to a standard, fossil fuel powered, car. When approaching the destination, Vie will offer parking assistance. If enabled, Vie’s built-in solar parking system will use height maps, weather data and a parking probability map to guide you to a free parking spot. The chosen parking spot is the one within range of the destination which yields the most solar energy.
While driving Stella Vie uses the latest V2X technology to warn the driver to anticipate upcoming traffic events, which allows for safer and more efficient driving. Finally, it also encourages the user to drive as efficiently as possible by giving subtle feedback through a built-in lighting system, this system warns the driver by turning red when either braking or accelerating too fiercely.

 

 

The car for everyday life

Vie, which is French for “life”, is the car for everyday life. Although she is lower than conventional cars, due to her big doors and handles she is easy to enter. Inside she provides a comfortable driving experience due to ergonomically optimised seats, a clean and spacious interior and intuitive controls for both driving and infotainment. A futuristic solar car that is ready for today! But that’s not all. Vie also stands for the Roman numeral “V”, or 5, as Stella Vie is the first solar powered family car ever to seat five persons!
