GMC Sierra EV Towing Capability: What to Expect
Towing with an electric truck raises different questions than towing with a gas truck. Here's what the Sierra EV actually delivers.
Maximum Towing Capacity
The Sierra EV is rated up to 12,500 pounds of maximum towing capacity, putting it solidly in the range of capable half-ton and beyond gas trucks, backed by up to 785 lb-ft of instant torque that makes getting a heavy trailer moving noticeably easier than with a gas engine building power gradually.
Why Instant Torque Matters When Towing
There's no waiting for the engine to spool up or the transmission to find the right gear under load — the full torque band is available from a stop, which is where towing a heavy trailer is usually hardest on a gas powertrain.
Range While Towing
The tradeoff is range. Towing near maximum capacity typically drops you to roughly 40-50% of the truck's normal range. On the Max Range battery, that still works out to an estimated 190-240 miles before you need to plan a charging stop — enough for most day trips, but it does require more route planning than a gas truck and a jerry can.
Added Stability From Weight
The Sierra EV's battery pack adds substantial weight low in the chassis. While extra weight isn't always a selling point, more weight in the tow vehicle relative to the trailer meaningfully improves towing stability, especially at highway speeds.
Planning a Tow Trip
If you're planning a long tow, map your charging stops ahead of time the same way you'd plan fuel stops with a gas truck — the difference is charging takes longer than a fill-up, so build that into your schedule rather than discovering it mid-trip.
Frequently Asked Questions
What is the Sierra EV's maximum towing capacity?
The Sierra EV is rated up to 12,500 pounds of maximum towing capacity, backed by up to 785 lb-ft of instant torque.
How much range do you lose while towing?
Towing near maximum capacity typically drops range to roughly 40-50% of the truck's normal range, though the Max Range battery still delivers an estimated 190-240 miles under those conditions.
Why does the Sierra EV tow more stably than some gas trucks?
Its battery pack adds substantial weight low in the chassis, and more weight in the tow vehicle relative to the trailer meaningfully improves towing stability, especially at highway speeds.
How should I plan a long tow trip?
Map your charging stops ahead of time the same way you'd plan fuel stops with a gas truck, but build in extra time since charging takes longer than a fill-up — planning ahead avoids surprises mid-trip.
