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.

The anatomy of performance: can Oxford find a way to measure the thrill of driving?

The same car, on the same road, can feel very different depending on who’s driving. Which makes this a little more complicated than checking a stopwatch. Together with researchers from the SDG Impact Lab at the University of Oxford, we set out to better understand the thrill of driving and explore whether it can be measured. The anatomy of performance follows that work across four episodes.

Performance meets performance

What defines the perfect shot? Absolute precision. In tennis, the greatest victories often come down to razor-thin margins. A shot that’s too long sails out of bounds. A shot that’s too short leaves an opening for your opponent. It is in the smallest gap between the two, where power meets precision, that great careers are made and inspiring stories begin. For Félix Auger-Aliassime, the quest for precision drives every match he plays. He spends thousands of hours repeating the same motion, fine-tuning every detail so that power, finesse, and control all come into play.
