Frequently asked questions
- What affects EV range?
- Temperature (cold reduces range), speed (highway driving is less efficient), climate control use, and payload all affect real-world range. Efficiency drops ~20–40% in winter.
- Why is usable battery less than total capacity?
- EV manufacturers reserve a buffer at the top and bottom to protect battery health. A 75 kWh pack typically has about 67–72 kWh usable.
