Both models are also exceptionally energy-efficient in terms of mileage. Where they vary, however, is in power, payload, and fuel economy ratings.

• Prepared to tow up to 12,500 pounds, both trucks are purpose-built for shouldering the needs of a general contractor or plumbing crew. They can trailer skid steers, mini excavators, and other vacation-friendly quarry such as RVs and boats.
• The 2027 Sierra EV produces anywhere from 625 to 760 horsepower, depending on your choice of its three engines. At the same time, the 2027 Silverado EV offers four engine options and produces 510 to 750 horsepower.
• They differ in what they can haul; where the Sierra EV can transport up to 2,250 pounds in its bed, the Silverado EV can carry up to 1,800 pounds. Both ratings are high enough to handle pallets of building materials, construction supplies, and landscaping equipment.
• Both pickups' electric ranges are comparable, making them well-suited to long drives between work orders. The Sierra EV can get up to 75 mpge city and 61 mpge on the highway, meaning anywhere from 283 to 410 miles of total driving range, depending on the setup. Designed to be more of a work truck, the Silverado EV has the edge, achieving up to 78 mpge in the city and 63 mpge highway, which equates to anywhere from 286 to 493 miles of total driving range.

The pickups converge when it comes to accommodations for day-laborers and crew chiefs alike. They diverge somewhat in whom they cater to.

• Ever the definition of capacious and comfortable for the requirements of project managers, the 2027 GMC Sierra EV comes in a crew cab configuration. It features an interior insulated for quietude, with sound-deadening material, acoustic glass, sumptuous open-pore wood accents, and available leather upholstery. With a nearly six-foot bed and a sizable front trunk, you'll have ample space to store a laptop, duty roster, and other workday essentials.
• A top choice of utilities workers and public works teams, the cabin in the 2027 Silverado EV is designed to be utilitarian, with a spacious crew cab that features more durable leatherette seating and comparable storage between the dashboard and center armrest. Likewise, its bed measures just under six feet long, providing plenty of room for tools and equipment.

• The 2027 Sierra EV features a massive 16.8-inch infotainment system with a Bluetooth interface for smartphone integration, plus an 11.0-inch digital gauge cluster that displays key metrics at a glance. Its standard wireless charging system keeps mobile devices powered and ready to keep in touch. Upgrade from the standard six-speaker audio system to a seven-speaker Bose setup to take your entertainment to the next level during the commute; several specialized braking and assistance systems help you stay in your lane and avoid pedestrians along the way, and the standard Super Cruise system enables automated driving with limited feedback on select roads across the United States.
• Similarly equipped, the 2027 Silverado EV has a generous 17.7-inch touchscreen, Bluetooth connectivity, an 11.0-inch digital gauge display, and six-speaker and Bose seven-speaker audio options. Its suite of smart driver aids is comparable, and it features built-in Google tech, including Google Maps navigation to help you stay on track. A standard Wi-Fi hotspot lets you access the Internet during service calls.
