Energy positive family car

Stella Lux, the energy positive family car. This means she is so efficient that she generates more energy than she consumes during the entire year, even in Dutch weather conditions! The aerodynamic design has an important role in this: consider, for example, the tunnel which runs through the center of the car. Furthermore, Stella Lux has an extended roof on both sides of the car. Because of this, we were able to place another row of solar panels on the car. Stella Lux is designed to be extremely light by using materials like carbon fibre and aluminium.

Intelligent car

Stella Lux is an intelligent car. For example, it contains an innovative energy management system: the Solar Navigator. By collecting the current weather data Solar Navigator gives suggestions for the optimal route. Furthermore Stella Lux is synchronized with your smartphone, because of this Stella Lux is up to date about your appointments during the day.

By combining the flexible screen layout of a tablet and haptic buttons, we developed Layr. By scrolling the tangible bar over the screen applications are maximized or minimized. Three gaps in the bar direction your fingers to the right spot, so you won’t have to look at the touchscreen to operate it. Because of this Layr increases safety.

Stella Lux communicates with other cars on the road. For example, the music volume automatically turns down when an ambulance is approaching.


No other solar car has the same comfort as Stella Lux. The beautiful interior appears after the door is automatically unlocked when Stella Lux detects your smartphone nearby. The door itself is part of the seat which gives you a spacious interior experience. The seats are equipped with comfortable textile in combination with lightweight pillows which let you enjoy maximum comfort. The rest of the interior is designed with bright colors and materials. This gives the interior of Stela Lux an open and bright appearance. The moodlights that are cleverly installed through the entire car makes you imagine you are driving in a futuristic mini-lounge.
