Polestar and the University of Oxford put 12 drivers in eye trackers and heart-rate monitors and sent them around a Swedish racetrack in two versions of the Polestar 4. The goal was to put numbers on something no spec sheet captures: how performance feels to the person driving.

The 544 hp Polestar 4 Dual motor with Performance pack delivered 32% higher peak acceleration than the 268 hp Rear motor version on matched laps, and it needed 15% less steering effort to do it. Drivers also rated it far higher on the experience.

Polestar launched the Polestar 4 SUV today, a new body style of its compact executive electric SUV that starts at €57,900 and delivers up to 630 km of WLTP range.

The bigger news for anyone who followed the original car: unlike the Polestar 4 coupé, the SUV has an actual rear window.
