on an 18-mile route that is typical of everyday usage combining traffic-congested urban roads, residential roads, open stretches, and twisty country roads. All of them were listening to a predetermined playlist on the same volume level with fixed sound settings, while an Empatica E4 medical-grade wearable device recorded their biometric measurements.
The results showed that participants drove up to four times more efficiently while listening to Beethoven compared to certain other tracks. On the other hand, the up-tempo hit song of The Weeknd made them twice as inefficient, prompting them toextracting more performance but also draining the battery faster. Finally, Adele’s ballad was somewhere in between, prompting an “emotive driving style” affected by the song’s crescendos.
The average range expenditure was 22.48 miles over the 18-mile course. Out of the range expenditure, classical music accounted for 7.7 percent, ballad songs accounted for 13.3 percent, while up-tempo pop music accounted for 23.6 percent. The study was overseen by Dr. Duncan Williams, a lecturer at the University of Salford’s School of Science, Engineering and Environment and an expert in acoustics, noise, psychoacoustics, and sound science.
After analyzing the data, Dr. Duncan Williams concluded: “What we found from only two days of testing was that music really can have a dramatic influence on the real-world driving range of an electric vehicle. Different songs resulted in varying electrodermal activity and blood volume increase for each of the participants. This had a knock-on effect on driving style, and ultimately influenced the real-world driving range of the EV6.
