What different trailer types mean for range
The type of trailer you tow dramatically affects range loss. These typical reductions show the impact of different trailer categories.
EV truck owner
Plan trips with your travel trailer or boat knowing exactly how far you can go between charges and where to stop.

Estimate real-world range with your camper so you can choose campsites and charging stops with confidence.
Boat owner
Know how far you can tow your boat to the launch ramp and whether you have enough range for the return trip.
Fleet operator
Evaluate whether EV trucks can handle your towing routes and plan charging infrastructure accordingly.

How towing affects EV range
Towing reduces EV range by 25–50% depending on trailer weight, aerodynamics, speed, and terrain. The reduction comes from increased aerodynamic drag and rolling resistance, which both increase energy consumption per mile.
Heavier loads and boxier trailers cause more drag. Speed has a nonlinear effect — towing at 55 mph preserves significantly more range than towing at 75 mph.

Tips for maximizing towing range
Reduce speed to mitigate range loss
Towing at 55 mph instead of 65 mph can reduce range loss by 10-15 percentage points. Aerodynamic drag increases with speed squared, so slower speeds save disproportionate energy.
Choose an aerodynamic trailer
Teardrop and aerodynamic travel trailers cause significantly less range loss than boxy ones. Rounded fronts, tapered rears and smooth undersides all help reduce drag while towing.
Plan more stops, not fewer
Expect 2-3 times the usual number of charging stops. Use EV trip planners and filter for chargers that can accommodate trailers. Consider charging to 80% to minimize stop duration.
Use Tow Mode and regenerative braking
Tow Mode optimises battery cooling and stability systems. Maximise regenerative braking in hilly terrain to recover energy on descents. Pre-condition the battery before fast charging.
Why towing kills EV range
Towing impacts EV range through two main mechanisms: aerodynamics and weight. At highway speeds, a boxy trailer can double your effective frontal area, dramatically increasing drag. Weight adds rolling resistance and requires more energy for acceleration and climbing. Because EVs recover energy through regenerative braking, the net penalty is partially offset in stop-and-go driving, but on sustained highway trips, the aerodynamic penalty dominates.
Physics of towing
The energy required to tow is proportional to total weight (vehicle + trailer) for acceleration and climbing, and proportional to frontal area × drag coefficient × speed² for aerodynamic drag. Towing adds 1,000-8,000+ lb of weight and 2-4x the aerodynamic drag area. This can increase energy consumption per mile by 30-100%, directly reducing range proportionally.
Speed impact on towing range
Speed has a nonlinear effect on range when towing. At 55 mph, aerodynamic drag is manageable; at 75 mph, drag is nearly double. EV range at 55 mph with a moderate trailer might be 180 miles, while the same setup at 75 mph might only achieve 120 miles. Reducing speed is always the most effective way to extend towing range.
Trailer type matters
A small utility trailer with mesh sides causes ~15% range loss. A teardrop camper (~25% loss) is aerodynamic but heavy. A full-height travel trailer (~40% loss) combines large frontal area with significant weight. A large fifth-wheel RV (~50% loss) is the worst case. Choose the most aerodynamic trailer that meets your needs if EV range is a concern.
Frequently asked questions
How much range do I lose when towing with an EV?
Range loss varies from 15-50% depending on trailer type, weight, speed and terrain. A small utility trailer might reduce range by 15-20%, while a large travel trailer or boat can cut range by 40-50%.
Why does towing reduce EV range so much?
Towing increases aerodynamic drag (especially with boxy trailers), adds rolling resistance from extra weight, and requires more energy for acceleration and hill climbing. EVs are already very efficient, so the added load has a proportionally larger impact than on gas vehicles.
Does speed affect towing range more in an EV?
Yes. Aerodynamic drag increases with the square of speed, and towing adds a large drag multiplier. Towing at 55 mph vs 65 mph can reduce range loss by 10-15 percentage points. Slowing down is the single most effective way to preserve range.
What trailer type causes the least range loss?
Small, lightweight, aerodynamic trailers cause the least range loss. Teardrop campers (~15-25% loss) and small utility trailers (~15-20% loss) are the most EV-friendly. Large boxy travel trailers and enclosed cargo trailers cause the most loss.
How much does trailer weight vs aerodynamics matter?
Both matter, but aerodynamics often matter more at highway speeds. A heavy but aerodynamic trailer may cause less range loss than a lightweight boxy one. Below 45 mph, weight has a bigger impact; above 45 mph, aerodynamics dominate.
Can I improve towing range by driving differently?
Yes. Reduce speed, use regenerative braking actively, accelerate gently, maintain steady speeds, reduce HVAC usage, and plan routes with fewer hills. Using Tow Mode optimises battery thermal management for sustained loads.
How many extra charging stops does towing require?
Towing can double or triple the number of charging stops needed. A 250-mile trip that normally requires one stop might need 2-3 stops when towing. Plan routes carefully and use apps that show charger locations along your route.
Do EV trucks have better towing range than cars?
EV trucks like the F-150 Lightning, Rivian R1T and Cybertruck have larger batteries (100-200 kWh) specifically designed for towing, but they still lose 25-50% of range when towing at capacity. Their advantage is longer baseline range, not better towing efficiency.
How does terrain affect EV towing range?
Hilly terrain amplifies range loss from towing. Climbing hills requires significant energy, and while regenerative braking recovers some energy on descents, it does not fully compensate. Mountain driving while towing can reduce range by 50-60%.
Is it better to tow a trailer or carry cargo in the vehicle?
Carrying cargo inside the vehicle (up to the payload limit) causes less range loss than towing because aerodynamic drag is not affected. Use a roof box only when necessary as it also hurts aerodynamics. For heavy loads, towing is often the only option.
