How does passenger and cargo load affect an EV’s range?

Passenger and cargo load can have a noticeable impact on an electric vehicle’s (EV’s) efficiency and driving range, especially in certain conditions.

How Extra Weight Affects Range

  • Acceleration: More mass requires more energy to move, particularly in stop-and-go traffic.
  • Climbing Hills: Additional weight increases the load on the powertrain when going uphill, reducing range.
  • Regenerative Braking: Heavier loads can improve energy recovery during braking, slightly offsetting the range loss in some cases.

Real-World Impact

While a few extra passengers or bags might only reduce range by 1–5%, a fully loaded EV with passengers and gear—especially on long or hilly trips—can see a 10–20% range drop depending on conditions.

Tips to Minimize Range Loss

  • Avoid unnecessary cargo when possible.
  • Keep tire pressure at recommended levels to reduce rolling resistance.
  • Use Eco or Range modes if available to optimize efficiency.
