Polestar 1 - World premiere in Shanghai. Polestar has a long history of working with supplier Öhlins to develop suspensions for it’s previous Volvo-based performance cars. For Polestar 1, Öhlins has developed a new Continuously Controlled Electronic Suspension (CESi) where each shock absorber is fitted with a new electronic valve that constantly monitors the driver inputs and road surface conditions, reacting in two milliseconds, to immediately change the ride characteristics according to road conditions. For the first time on an Öhlins suspension, the driver can also make changes to the suspension settings within the car, constantly able to tailor the chassis damping and ride quality to their own requirements.
