FREYR

Freyr-1 was SolarMobil's first car. The car marked the inception of the student collective project -SolarMobil in 2011. The designing, manufacturing and assembly of the car was carried out in-house by the SolarMobil team. Freyr-1 is a single-seater, three-wheeler solar racing car. The most notable features of this car were its lightweight space frame chassis, the custom-made suspension system, and its ability to drive directly on solar power using a high-power-efficiency drive train.

The most notable features of this car were clean and free fuel with zero emissions and zero noise pollution. It is built with AISI 4130 Chromoly steel chassis which gives it high strength-to-weight ratio and Fibre Reinforced Plastic body making it lightweight. The solar panels with a 6m2 area constitute the top of the car. The car adheres to World Solar Challenge specifications and belongs to the ‘Adventure Class’ category of solar vehicles.
