Abstract
In this paper, we explore the differences in vehicle dynamics and drivers´ behaviour between electric cars (ecars)
and conventional cars with combustion engine. Our research aimed at revealing potential safety risks due to
a higher e-car penetration, e.g. incidents or conflicts with other road users that primarily occur with e-cars
involved. To do this, we conducted a real-world driving study with 90 participants on a pre-defined route. Each
participant had to complete the route with an electric as well as a similar conventional car that both recorded
video, GPS data and 3D accelerations. Our results show that the effects of an electric engine on "non-extreme"
vehicle dynamics are negligibly low compared to other factors such as transmission type. Surprisingly high
decelerations were measured during the e-car´s recuperation phases, which might lead to risks for follow-up
drivers. The analysis of questionnaires showed that the participants felt safe and got used to the e-car quickly.
