GMC Sierra EV vs Rivian R1T
Which Electric Truck Wins for Colorado?
By Ryan Green, Marketing Director — Weld County Garage GMC | Updated June 2026
Electric trucks have arrived in Northern Colorado, and the two that matter most are the GMC Sierra EV and the Rivian R1T. Both are capable, quick, and tech-loaded — but on the numbers that count for Colorado buyers, one pulls ahead.
Quick Answer
The GMC Sierra EV out-tows (12,500 vs 11,000 lbs), out-ranges (up to 478 vs 420 miles), and undercuts the Rivian R1T on price — and it qualifies for the up-to-$7,500 federal tax credit, which the R1T may not.
The R1T counters with a proven adventure brand and a polished cabin. For most Colorado work-and-tow buyers, the Sierra EV is the value pick.

Real-World Range
Range & Charging in Colorado
On paper the Sierra EV's Max Range battery leads at up to 478 miles. Real Colorado range is lower — expect 20–30% loss in deep winter cold and at altitude, and a steeper drop when towing. Both handle a Greeley-to-Denver round trip easily; the gap shows on longer mountain hauls. The Sierra EV's 800V architecture also adds range faster on a DC fast charger, which matters when you're topping up in the high country.
Work Capability
Towing, Payload & Bed Practicality
The Sierra EV tows up to 12,500 lbs — 1,500 more than the R1T — for horse trailers, campers, and equipment. The R1T edges payload slightly (2,317 vs 2,250 lbs). Where the Sierra EV pulls away is the bed: the MultiPro Midgate and six-function MultiPro Tailgate deliver over 10 feet of cargo length, plus a larger 11 cu ft frunk. For trades and serious haulers, it's the more versatile work truck.
The Money
Price & the $7,500 Tax Credit
The Sierra EV Elevation starts about $8,600 below a comparable R1T, and it's built to qualify for the federal EV tax credit of up to $7,500 — a swing the R1T may not match for every buyer. Stack the lower MSRP and the credit and the value gap widens further. Confirm current eligibility before you buy.
Which is right for you? Choose the Sierra EV for towing, range, value, and tax-credit eligibility. Choose the R1T for the adventure brand, gear tunnel, and a slightly higher payload.
