Electric vehicle manufacturer Polestar, in collaboration with the SDG Impact Lab at the University of Oxford, conducted an exploratory study aimed at measuring intangible factors in the driving experience by converting the "sporting performance feel" into digital indicators subject to laboratory and field analysis.
The experiments took place at the Gotland Ring in Sweden, with the participation of 12 drivers equipped with precise technical gear including eye-tracking devices, heart rate monitoring sensors, and EEG caps to measure physiological signals, alongside the recording of complete telemetry data emitted by the vehicle systems while driving in calm and high-speed dynamic conditions.
Performance and Muscle Effort Comparison
The experiment relied on comparing two different versions of the Polestar 4 model; the first features a single rear motor generating 200 kW (equivalent to 268 hp), and the second features a dual motor equipped with the Performance pack delivering up to 400 kW (544 hp). The results recorded during laps of identical speed showed that the more powerful version achieved a peak acceleration 32% higher compared to the standard version, with a noticeable 15% decrease in the effort exerted to steer the steering wheel.
According to the data, the reduced effort and more precise steering positively reflected on drivers' confidence, as the Performance pack version scored 89.2 out of 100 points on the dynamic performance scale compared to 67.7 points for the rear-motor version, while the overall experience quality index rose to 93.0 compared to 77.9 points.
Physiological Interaction and Deeper Focus
Researchers monitored clear physiological changes accompanying dynamic driving; eye blink rate decreased and drivers' pupils dilated with fixed gazes for longer periods on points of the track layout, which the research team interpreted as increased mental focus and attention sharpness. The analyses linked moments of sharp maneuvering to elevated levels of controlled physiological arousal.
In subsequent interviews, participants described the driving experience as resembling a "fully controlled roller coaster," emphasizing that performance is not limited to instantaneous thrust, but is closely tied to the feeling of confidence and the ability to predict the car's response.
What Do These Results Mean for the Electric Vehicle Industry?
Manufacturers seek to move beyond traditional metrics, such as zero-to-100 km/h acceleration figures and horsepower numbers written in specification tables; many electric vehicles today share similar initial acceleration figures, while true differentiation lies in the software calibration of steering systems, dynamic torque distribution, and suspension systems. University of Oxford researcher Max Klapow explains that true performance is not about sheer speed as much as it is about giving the driver a sense of confidence through expected and smooth responses from the vehicle.
Study Limitations and Boundaries of Results
Despite the study's implications, its organizers emphasized that it remains a pilot study relying on a very limited sample of only 12 individuals and used cars belonging to the sponsoring entity, which requires conducting expanded and independent research to scientifically confirm the validity of these results and generalize them to future electric vehicle engineering standards.
