It'll come down to which badge you prefer.
GMC unveiled the 2024 Sierra EV last week, and its output figures were quite shocking. We expected the figures to match those of the Silverado EV, which made its debut in January this year. Both cars are built on the same platform, after all.
At first, we thought the additional power would be a selling point to lure customers into the seemingly more upmarket Sierra EV. When it first made its debut, the top-trim Chevrolet boasted 664 horsepower and 780 lb-ft. That was enough power to get it to 60 mph in 4.5 seconds. More importantly, the estimated range was set at 400 miles. The GMC made its debut with the same dual-motor setup but with a GM-estimated 754 hp and 785 lb-ft of torque.
Chevrolet's website has been updated, and the output figures match the GMC. Oddly, the rest of the claimed figures remain the same. The additional 90 hp and five lb-ft make no difference to the performance.
Chevrolet still claims a towing capacity of 10,000 pounds, while the GMC has to make do with 9,500 lbs. Chevy's future Work Truck can tow up to 20,000 lbs, but GMC is keeping mum on its future trims for now. We know that the AT4 and Elevation trims will only be available in 2025.
"As we prepare for production of the Silverado EV, our engineering team has further refined the estimated performance specs for the 2024 Chevrolet Silverado EV RST First Edition. GM now estimates horsepower to be up to 754 and torque up to an estimated 785 lb-ft when Wide Open Watts mode is engaged," GM said in an e-mail to Motor1.
Wide Open Watts Mode (WOW) is the Chevy's most aggressive driving mode and exists purely to embarrass hot hatches off the line. The GMC is equipped with Max Power mode, which does the same. It's merely a continuation of GM's grin-inducing acronyms like the WTF (Watts To Freedom) Mode found on the Hummer EV.
We find it interesting that GM suddenly switched to a new term with the introduction of the Sierra EV. As mentioned earlier, it comes with a "GM-estimated" 754 hp power rating. That means GM is not ready to commit to a power figure just yet. At least the power figures are moving upward and not in the other direction.
This suggests that GM is still refining both trucks and is perhaps applying lessons learned from the struggling Hummer EV. The Silverado and Sierra will only be available from 2024, giving GM more than a year to further cultivate both models.
