Known as Polestar Performance Optimization and previously offered on other Volvo models, the package is centered around software tweaks rather than hardware upgrades. Actual performance figures probably won't change, but Volvo says the upgrades will improve throttle response, shift times, and "overall engine performance." Volvo also claims tuning was done with input from drivers and engineers of the Polestar Cyan Racing team, which competes in the FIA World Touring Car Championship.
