The instant upgrade adds 68 horsepower and 15 pound-feet of torque to the dual-motor powertrain, for a total output of 476 hp and 502 pound-feet of torque.
Behind the wheel, the performance boost delivers increased responsiveness and a sportier experience overall, Polestar said.
The additional power and torque are primarily felt at speeds between 44 and 80 mph, resulting in even, rapid mid-range acceleration. With the upgrade, accelerating from 50 to 75 mph takes 2.2 seconds – half a second quicker than a standard Polestar 2.
“This upgrade highlights how connected technologies can transform the relationship a car company has with its customers,” Polestar CEO Thomas Ingenlath said in a statement.
