Lynx -act for motion / city vehicle

Lynx -act for motion
Lynx -act for motion

Lynx is an urban vehicle powered both manually and via an electric motor. Solar cells on the vehicle roof can permanently generate energy, which can be accumulated and stored. The solar panels are one square meter in size and can move the car 18 km per day.

The pedal is the operator's central interface to the vehicle. The harder one pedals, the faster the car accelerates. The motor supplements the supplied manual power, allowing the car to reach up to 70 km/h. Through this process, the driver receives feedback on how much engine power is converted and can sense the relationship between energy and motion.
