Not necessarily. A 2025 survey in mainland China found that passengers reported motion sickness more often in fuel vehicles, but that symptoms were more severe in electric vehicles (EVs). A separate, small on-road experiment found more participants experienced sickness with higher regenerative braking. These findings suggest that driving dynamics and passenger circumstances matter; they do not show that EVs universally cause carsickness.
What does “more likely” mean?
It can mean having motion-sickness episodes more often, or having worse symptoms when they occur. Those outcomes did not point in the same direction in the available direct comparison.
| Outcome | What the 2025 survey found | What that finding can establish |
|---|---|---|
| Reported frequency | Higher in fuel vehicles | An association in respondents’ reports, not proof that fuel vehicles cause more episodes |
| Reported severity | Greater in EVs | An association in respondents’ reports, not proof that EVs cause worse symptoms |
The survey by Weiyin Xie, Chunxi Huang, Jiyao Wang, and Dengbo He collected 639 valid responses in mainland China about passenger experiences over the previous year. It was self-reported and observational, not a controlled test assigning otherwise comparable passengers to EVs and fuel vehicles. It also is not a representative estimate of motion-sickness rates worldwide. Read the survey study.
Could regenerative braking make some passengers feel worse?
It is a plausible contributor, with preliminary experimental evidence. In a 2025 on-road within-subject study, researchers tested 16 participants susceptible to motion sickness under low- and high-level regenerative braking, with auditory motion cues either present or absent. The highest share of participants experiencing sickness occurred with higher regenerative braking. The authors wrote, “Our results confirmed that higher levels of regenerative braking led to the highest percentage of passengers experiencing MS.” Read the study manuscript.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
The small study does not show how often typical EV passengers will feel sick, or establish a setting that will prevent symptoms. It also found that auditory cues mitigated symptoms under high-level braking, but had negligible or possibly adverse effects at low-level braking. That result is not a basis for treating sound cues as a guaranteed remedy.
Why might an EV’s motion feel different?
The researchers discuss rapid electric-motor response, reduced engine sound that might otherwise help a passenger anticipate movement, and deceleration from regenerative braking as possible contributors. The braking experiment directly examined braking level and auditory cues; it did not independently prove each proposed mechanism. Treat these explanations as hypotheses, not a settled account of why any particular passenger feels sick.

More broadly, motion and predictability are relevant to vehicle sickness. A real-driving study associated greater lateral acceleration and less predictable vehicle paths with more severe symptoms. A systematic review and meta-analysis of experimental vehicle studies also discusses passenger status and visually demanding, non-driving tasks among relevant factors. These general vehicle findings help explain why rides can differ, but they are not evidence that EVs specifically cause more sickness. Real-driving study; Systematic review and meta-analysis.

In the China survey, reported severity was associated with individual differences, including age, gender, sleep habits, and susceptibility to motion sickness. It was also associated with activities such as chatting and watching in-vehicle displays, and with road conditions including congestion and slope. Reported frequency was associated with vehicle ownership and riding frequency. These are associations from the survey, not proof that any one factor causes symptoms.

Passengers may have less opportunity than drivers to anticipate or control changes in movement, but that does not mean every passenger will feel sick. The vehicle, route, activity, and individual passenger all form part of the experience.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What can you take from this as a passenger?
- Do not treat the EV-versus-fuel-vehicle question as a single yes-or-no comparison: reported episode frequency and symptom severity differed in the survey.
- Smooth, predictable acceleration and braking are reasonable comfort considerations given broader evidence on motion and predictability, but the cited studies do not establish them as a medically tested treatment.
- The braking experiment is limited to 16 susceptible participants, so it cannot tell every EV owner or passenger which setting to use.
If symptoms are persistent or severe, these vehicle studies do not assess clinical causes or treatment. The evidence here cannot substitute for medical advice.
