Creating Allsvinn

Moving to carbon fibre

For Allsvinn, the choice was made make the body from carbon fiber rather than the natural fibres that had been used in the 2021 car. The increased structural strength from the carbon weave is a crucial part in making a car meant to take on the worlds greatest.

Steel space frame

The frame is made of SSAB Docol R8 steel tubes. Docol steel is widely used in racing because of its extreme strength to weight ratio, allowing the car to remain both ridgid and safe during racing but also light enough not to be a hindrance in terms of rolling resistance and drag.
