Polestar's chassis team is tuning the Polestar 1 handling balance in extreme winter conditions. Polestar's chassis engineer and test driver Joakim Rydholm is leading the handling evaluation process.
Polestar 1 winter test
Watch how the Öhlins shock absorbers combined with different rear anti-roll bar settings are tested and evaluated at high speeds. Each setting step is half a millimeter in difference, from a 20 to a 25-millimeter diameter. Top speed in the test drive is 200 km/h (124 mph). The Polestar 1 prototype car used in the test is stripped of all driver support systems so that the test driver can feel the exact base chassis settings. These tests are performed on a closed test track located in Sweden, just inside the Arctic Circle. The temperature is -25°C (-13 °F).
