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.
