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 millimetre apart, from a 20 to a 25-millimetre diameter. The top speed in the test drive is 200 km/h. The Polestar 1 prototype used in the test is stripped of all driver support systems so that the driver feels nothing but the exact base chassis settings. These tests are performed in a closed test track located in Sweden, just inside the Arctic Circle. Its average temperature is -25°C.
