EV Towing Range Calculator
Towing is the single biggest hit to EV range. Pick a vehicle and a trailer weight to see how far it can really go with a trailer behind it — and how much of that loss is aerodynamics versus weight.

Trailer shape
Standard box-front travel trailer or small RV — shape matters more than weight at highway speed.

Plan a charging stop roughly every 168 mi when towing — you want to stop and recharge before dropping below ~20%, and DC fast sites that fit a truck and trailer are still scarce.

How towing affects EV range
A trailer attacks range in two ways. The big one is aerodynamic drag: a box-shaped travel trailer can triple the frontal area pushing through the air, and because drag rises with the square of speed, that cost explodes on the highway. The second is weight: a heavier rig needs more energy to overcome rolling resistance and to climb grades. On flat ground at 65 mph, aerodynamics usually account for the majority of the loss — which is why a tall, flat-fronted camper costs more range than a heavier but low, open utility trailer.
Put together, most EVs lose 40–55% of EPA rangewith a mid-size travel trailer near their tow rating. That turns a 410-mile Rivian R1T into a ~200-mile tow rig and a 320-mile F-150 Lightning into a ~150-mile one. The percentage is similar to a gas truck's mpg hit, but it bites harder because the starting range is shorter and recharging takes 30–45 minutes instead of five. The practical consequence is planning: you stop more often, and you need DC fast sites that physically fit a truck and trailer.
Range loss by vehicle
Every US EV rated to tow 3,500 lb or more, with an estimated towing range for a mid-profile box travel trailer loaded to 75% of each vehicle's max rating at 65 mph. Use the calculator above to model your own trailer and speed.

| Tesla Cybertruck LR RWD | 350 mi | 11,000 lb | ~173 mi | −51% |
| Rivian R1T Max | 410 mi | 11,000 lb | ~202 mi | −51% |

Tips to maximize EV range while towing
- Slow down.Drag scales with speed squared, so dropping from 70 to 60 mph can recover 15–20% of your towing range. It's the single most effective lever you have.
- Pick the most aerodynamic trailer you can.A low, tapered teardrop or a sleek boat trailer costs a fraction of what a tall box camper does. If you're shopping for a trailer to tow with an EV, frontal area matters more than weight.
- Precondition and charge to 100% before you hook up. Unlike daily driving, towing days are the time to use the full pack. Warm the battery while plugged in so your first leg and your first fast-charge stop both run at full efficiency.
- Plan stops every ~80% of your estimated range. Recharge before you drop below ~20%, and scout DC fast sites with pull-through stalls in advance — many car-oriented stations can't fit a truck and trailer without unhitching.
- Mind tongue weight and tire pressure. Proper tongue-weight distribution keeps the rig stable (and safe), and running tires at the correct towing pressure trims rolling resistance.
- Expect a bigger hit in the cold. Winter towing stacks battery-chemistry losses and cabin heating on top of the aerodynamic penalty. Pad your estimate by another 10–20% below 30°F.
Frequently asked questions
How much range does towing use in an EV?+
Expect to lose 40–55% of your EPA-rated range with a typical box travel trailer at highway speed. A Rivian R1T rated at 410 miles drops to roughly 180–210 miles; an F-150 Lightning rated at 320 miles falls to about 130–160. The loss is mostly aerodynamic, so a low boat trailer or open utility trailer costs far less than a tall, flat-fronted camper of the same weight. Light loads under 3,000 lb at moderate speed can keep you above 70% of EPA range.
Why does towing cut EV range so much more than gas?+
It cuts gas range too — a gas truck towing near its max often loses half its mpg. The difference is the starting point and the refuel. A gas truck still has 200+ miles of towing range and refuels in five minutes; an EV starts with less range and a DC fast charge from 10–80% takes 30–45 minutes. So the same percentage loss feels much bigger because the absolute towing range is shorter and stops are longer.
Does trailer weight or trailer shape matter more?+
Shape, at highway speed. Aerodynamic drag scales with the square of speed and depends on the trailer's frontal area and how flat its face is. A 7,000 lb enclosed box trailer costs more range than a 9,000 lb open flatbed with a tractor on it, because the box pushes far more air. Weight still matters — it drives rolling resistance and the energy to climb grades — but on flat highway, aerodynamics dominate. This calculator models both, with shape weighted more heavily as speed rises.
How accurate is this estimate?+
It's a planning estimate calibrated to independent road tests (InsideEVs, MotorTrend, TFL Truck, Out of Spec Reviews), which consistently show 45–55% range loss for a mid-size travel trailer near max tow at 65 mph. Your real number depends on wind, terrain, temperature, and tongue weight — cold weather in particular can push losses past what this tool shows. Treat the output as a starting point and pad it with a safety margin, especially in winter.
What's the difference between this and the EV range calculator?+
The EV range calculator models everyday factors — temperature, highway speed, HVAC, payload, and state of charge — for driving without a trailer. This towing calculator isolates the single biggest hit to EV range and breaks it into the two causes that matter when a trailer is attached: aerodynamic drag and weight. Use this one when a trailer is involved and the range calculator for normal driving.
