Towing with an EV: range, strategy, and planning

The range reality

Towing a trailer dramatically increases aerodynamic drag and rolling resistance. Expect 40–60% range loss depending on trailer weight and highway speed. A Rivian R1T with 314 miles of unladen range realistically delivers 130–180 miles towing a 6,000 lb trailer at 65 mph. This is the number you must plan around, not the EPA number.

Calculate your towing range before you leave

Use a towing-aware planning app. ABRP (A Better Route Planner) has a towing mode that adjusts consumption estimates based on trailer weight, wind, temperature, and speed. Enter your actual trailer weight, not the maximum tow rating. This gives charging stop intervals you can actually hit.

• ·ABRP towing mode: enter trailer weight + weather
• ·Rivian: in-vehicle route planning accounts for trailer
• ·Rule of thumb: budget 60% of unladen range when towing
• ·Add 10% buffer: aim to arrive at chargers with 20%, not 10%

Choosing chargers with towing access

Not all fast chargers have pull-through stalls for vehicles with trailers. Look for Electrify America sites with truck-friendly spaces (listed in the EA app). Tesla Supercharger 4.0 locations often have pull-through stalls. Rivian Adventure Network sites are specifically designed for truck and trailer access.

Unhitching strategy

At chargers without pull-through access, you'll need to unhitch, charge, then rehitch. This adds 10–15 minutes per stop. For long hauls, this is a reasonable trade. Plan charger stops at locations where unhitching is practical — large parking lots, travel plazas.

Speed management when towing

Driving 60 mph instead of 70 mph while towing significantly improves range — aerodynamic drag from the trailer is the dominant force. The additional time is offset by needing fewer charging stops. On a 400-mile towing trip, driving 60 mph vs 70 mph might mean one fewer 30-minute charging stop.
