Chevrolet raised output on the top Trail Boss trim of the 2027 Silverado EV to 750 horsepower and 775 pound-feet of torque, 25 hp more than the outgoing model, and every 2027 truck now carries a factory NACS charging port. InsideEVs reported the changes on Nov. 5, adding that production of the model year began at GM’s Factory Zero in Michigan the month before.

The extra power has a condition. The peak figure is available only in Wide Open Watts mode, which Chevrolet says is not meant for everyday driving, and the company has not said what output the truck makes with that mode off. Prices rose on every trim as well, so buyers get more power in one trim and a bigger bill in all of them.
The Trail Boss Max Range numbers
The 750 hp rating applies to the Trail Boss with the Max Range battery, the longest-range truck in the lineup at up to 478 miles. InsideEVs’ rundown of the update says the other trims are unchanged: the WT makes 510 hp with either 490 or 580 lb-ft depending on battery size, the LT Standard Range 605 hp and 605 lb-ft, the LT Extended Range 645 hp and 765 lb-ft, and the Trail Boss Extended Range 625 hp and 775 lb-ft. All use a dual-motor, all-wheel-drive layout.
Chevrolet’s own Silverado EV page repeats the main specifications, adding a 0-to-60 mph time of under 4.2 seconds with Wide Open Watts in Sport Mode and available towing of up to 12,500 pounds. Off-road gear on the Trail Boss includes a two-inch lift, a more aggressive body kit, 35-inch tires, standard four-wheel steering and new driving modes.
New cabin features arrive across the range. Cabin Glance shows live interior video on the infotainment screen, Security Recording saves camera footage when the alarm triggers, and Surround Vision Recorder films continuously while driving, in the manner of Tesla’s Dashcam. GM’s earlier Sentry Mode announcement is the closest precedent for the security feature.
The Trail Boss Max Range is also the price leader. At $90,395 including destination, it costs $1,200 more than before, and InsideEVs notes the RST trim that used to top the range is gone. For buyers, the practical effect is that the quickest and longest-range version now sits at a price point where it competes with luxury electric SUVs rather than with other full-size pickups, and the power gain applies only when the truck is used in its most aggressive setting. The range figure, up to 478 miles, is a GM estimate that Chevrolet’s page attaches to the same Max Range configuration, and the 12,500-pound towing number is listed as available rather than standard, so the fully equipped truck is the one that matches the brochure.
A native NACS inlet and the adapter shuffle
With a built-in NACS inlet, the truck can use Tesla Superchargers and other NACS chargers without an adapter. GM Authority reported in August that the 2027 Silverado EV joins the models that ship with a factory-installed NACS port, following similar updates announced for the 2027 Blazer EV, Equinox EV and Sierra EV. Chevrolet is pulling the NACS DC and NACS Level 2 adapters from its accessories catalog and adding a GM J1772 AC Adapter, a GM CCS1 DC Adapter and a GM PowerShift AC Charging Adapter, plus three bundles that include them.
The switch completes a transition GM outlined in 2023 after its agreement with Tesla. In 2024 the company set 2026 as the first model year for native NACS ports, and the 2026 Cadillac Optiq was the first GM vehicle to get one. Chevrolet’s consumer page, as retrieved, does not mention NACS, so the port detail rests on the GM Authority and InsideEVs reports rather than a Chevrolet product page.
Prices, trims and sales behind the truck
Prices rose on every trim. InsideEVs lists the Standard Range base at $56,085 including destination, up $700, the LT and Trail Boss Extended Range trims up $1,000, and the Trail Boss Max Range at $90,395, up $1,200. The RST trim, once the top option, has been dropped. Chevrolet’s page quotes different starting figures, $61,900 for the LT and $71,000 for the Trail Boss, which reflect specific trims and equipment rather than the lowest-cost version.
Autoevolution, citing CarsDirect’s order guide in September, counted seven versions remaining: three Work Truck, two LT and two Trail Boss, with the 4LT discontinued. It also noted that Chevy dealers delivered 3,672 Silverado EVs in the second quarter of 2026 against 3,044 for the GMC Sierra EV, which it read as GM keeping the truck despite weak demand.
The open question is the Wide Open Watts caveat. Until Chevrolet publishes the output outside that mode, buyers comparing the 750 hp Trail Boss with the 725 hp figure from the earlier Trail Boss review cannot say how much of the gain exists in normal driving.
