GMC Sierra EV Denali towing range: Airstream comparison math
The Denali is the luxury GM big-pack comparator: air ride, four-wheel steer, Energy Transfer Pro, and a huge range number, with measured Wattreach towing data still pending.

What we can say with confidence.
Wattreach has photo-documented Sierra EV Denali context from Quartzsite with the Airstream and EV-truck crew, but no charge-to-charge Denali towing ledger yet.
- Official range:Up to 478 mi GM-estimated range with Max Range Battery Pack
- Official tow rating:Available tow up to 12,500 lb

Estimate this pack's towing range.
This is a planning estimate, not a measured Sierra EV Denali tow ledger. The Sierra EV Denali is a physically larger truck with a less aerodynamic shape and a less efficient motor and drivetrain than our R1T, so towing the same 23-foot Airstream it gives up real efficiency: we plan it at 1.00 mi/kWh, below the 1.19 mi/kWh our R1T measures across 4,405 towing miles. That estimate, multiplied by this truck's pack basis, is the math below.
205 kWh x 1.00 mi/kWh (truck-adjusted).
A realistic fast-charge hop before wind, grade, and arrival buffer.
Useful advantages.
- Max Range pack gives the largest planning buffer in this comparison
- Available Air Ride Adaptive Suspension and 4-Wheel Steer matter for trailer use
- Energy Transfer Pro can be valuable at camp
Range planning cautions.
- The published range is solo range, not Airstream range
- Big pack means big charge sessions when towing
- Wattreach has not measured Denali EV towing efficiency yet
