Towing & Extreme Weather

How much range you actually lose towing, driving in the cold, or driving in extreme heat.

Quick Answer

Towing typically cuts EV range roughly in half, and heavy loads or poor trailer aerodynamics can cut it more. Freezing weather usually reduces range by about 20-30%, while extreme heat costs less but increases air-conditioning draw. Preconditioning while plugged in recovers much of the cold-weather penalty.

Frequently Asked Questions

How much range do you lose towing with an EV?

Plan on approximately 50% of rated range with a typical trailer, and worse with a tall, boxy load at highway speed. Aerodynamics matter more than weight above about 55 mph.

How much range do EVs lose in cold weather?

Roughly 20-30% in freezing conditions, mostly from cabin heating and cold battery chemistry. Preconditioning the cabin and battery on shore power greatly reduces the hit.

Does hot weather hurt EV range?

Yes, but less than cold. Air conditioning and battery cooling draw power, and sustained high heat accelerates long-term degradation, so park in shade and avoid leaving the pack at 100% in extreme heat.
