According to Polestar Marketing Director Hans Bååth, "The performance concept road-car is a spinoff of our work evaluating and developing the S60 for racing."
Mum's still the word on exactly what lies under the hood of the new Polestar S60. Rumors have suggested either a Yamaha-sourced V8 (a version of the engine that is used in the XC90) or a boosted version of the turbocharged inline-six currently found in the S60. Guess we'll just have to wait until the 16th to find out.
