The 2027 Chevrolet Silverado EV Trail Boss Max Range gains 25 horsepower to reach 750 hp and 775 lb-ft of torque, while every trim in the lineup adopts a native NACS charging port for the new model year.
The Technical Reality of Wide Open Watts
The headline figure arrives with a caveat. That 750 hp peak is only available when the driver activates Wide Open Watts mode, a setting Chevrolet describes as pushing every metric to the top for maximum acceleration. The company does not disclose what the dual-motor powertrain produces when WOW mode is disabled, leaving the technical reality of day-to-day output an open question. Torque holds at 775 lb-ft regardless. Power figures for every other Silverado EV trim — WT, LT, and Trail Boss Extended Range — remain unchanged for 2027.
NACS From the Factory
The more consequential change sits under the hood of the charging architecture. All 2027 Silverado EV models now ship with a native North American Charging Standard port, the Tesla-originated connector that has become the de facto standard across General Motors’ EV portfolio. The switch grants direct access to the Tesla Supercharger network and other NACS-equipped chargers without the adapter that CCS-equipped GM vehicles have required since the partnership was announced. It is a running change that aligns the electric truck with the Cadillac Lyriq, Chevrolet Equinox EV, and the rest of the Ultium lineup already rolling out with the port.
Interior Surveillance
Inside, the 2027 model adds Cabin Glance, a feature that streams a live video feed of the vehicle interior to the infotainment screen. It joins Security Recording, which captures footage from onboard cameras when the alarm triggers, and Surround Vision Recorder, a continuous dashcam-style system that records while the truck is in use. The trio brings the Silverado EV’s camera suite into parity with the Tesla Dashcam and Sentry Mode ecosystem that has set the expectation for built-in vehicle surveillance.
Pricing and the Gas-Powered Context
The updates come with modest price increases across the board. The base Standard Range WT now starts at $56,085 including destination, up $700. LT and Trail Boss Extended Range trims rise $1,000, while the flagship Trail Boss Max Range climbs $1,200 to $90,395. GM Authority first reported the power increase and NACS adoption.
The electric truck’s evolution unfolds against a broader strategic shift at General Motors. The company has postponed development of its next-generation electric trucks in favor of investing in updated gas-powered models, a decision that places the current Silverado EV architecture in the lineup for longer than originally planned. The 2027 gas-powered Silverado 1500 arrives simultaneously with two new naturally aspirated V8s — a 5.7-liter and a 6.6-liter — joining the carryover 2.7-liter turbo four-cylinder and 3.0-liter Duramax diesel in a simplified seven-trim range. Those new V8s return 1–2 mpg less than the outgoing engines across city, highway, and combined cycles, with the 5.7-liter rated at 17 mpg combined in two-wheel-drive form and the 6.6-liter at 15 mpg combined in four-wheel-drive only. The gas truck goes on sale at the end of 2026.
Competitive Positioning
In the electric half-ton segment, the Silverado EV Trail Boss Max Range’s 750 hp in WOW mode slots above the Ford F-150 Lightning’s peak output and positions the Chevrolet as the most powerful factory-spec entrant until the Ram 1500 REV arrives with its range-extended architecture. The native NACS port removes the adapter friction that has been a practical annoyance for early GM EV adopters at Supercharger sites. Whether the undisclosed non-WOW output proves competitive in daily driving — towing, hauling, sustained grade climbing — remains the detail that matters for buyers who do not treat a 9,000-lb pickup as a drag-strip toy.
