2027 GMC Sierra 2500HD vs 2027 Ford F-250 Super Duty: Full Comparison
The 2027 GMC Sierra 2500HD reaches 38,000 lbs of available max towing with the new Duramax 8.3L Turbo-Diesel, surpassing the F-250's 23,000-lb rating. The Sierra HD also introduces segment-first electric rack-and-pinion power steering and the eBoost braking system, both absent on the F-250. This page breaks down every key difference and covers what shoppers can expect from the upcoming 2027 Sierra 2500HD at ASA Auto Plaza.
The Short Answer
Buyers who prioritize raw towing muscle and segment-first braking and steering technology have a clear winner in the 2027 Sierra 2500HD. Its available Duramax 8.3L Turbo-Diesel produces 555 hp and 1,230 lb-ft of torque, and it tows up to 38,000 lbs, a figure the F-250 does not match. The F-250 is a capable workhorse with a strong payload rating and broad trim selection, but the Sierra HD's engineering leaps in 2027 put it in a different tier for serious haulers.

GMC Sierra HD towing capability
On the gas side, the two trucks trade numbers closely. The F-250's 7.3L delivers 430 hp and 485 lb-ft, edging the Sierra's 6.6L at 412 hp and 472 lb-ft. Diesel is where the Sierra HD pulls decisively ahead: 555 hp and 1,230 lb-ft versus Ford's 1,200 lb-ft, and a towing ceiling that is 15,000 lbs higher.
Performance and Powertrain
The story of 2027 Sierra HD performance begins with the Duramax 8.3L Turbo-Diesel V8 paired to the Allison 10-speed automatic transmission. That combination generates class-leading diesel horsepower and torque and supports the 38,000-lb towing ceiling. The 6.6L V8 gas engine is standard across the lineup and runs on regular unleaded, making it the right pick for buyers who keep diesel costs and fueling logistics out of their daily math.
The F-250 also pairs a 10-speed automatic, the TorqShift unit, with its available 6.7L Power Stroke diesel. Ford's diesel reaches 1,200 lb-ft of torque, which is competitive, but the Sierra HD's 1,230 lb-ft edges it and the 38,000-lb tow rating is in a different category entirely.
Two Sierra HD systems set this truck apart from every competitor in 2027. Segment-first electric rack-and-pinion power steering replaces the hydraulic systems found in heavy-duty trucks today, including the F-250, delivering a more direct and precise feel at the wheel. The eBoost braking system, also a segment-first, is purpose-built to reduce trailering stopping distances and provide a firm, consistent brake response during downhill grades. Neither feature is present on the F-250.
The AT4X trim adds Terrain Mode, debuting on Sierra HD for the first time, which adjusts shift mapping, traction control, and braking automatically for low-speed off-road maneuvers. Multimatic DSSV dampers and a factory 1.5-inch suspension lift complete the AT4X picture.
Full 2027 Sierra HD trim breakdown
Interior, Space and Cargo
Both trucks seat six passengers, and both lineups reach into legitimate luxury territory at their top trims. The Sierra HD Denali Ultimate brings full-grain leather seating, authentic Paldao wood trim, and 16-way power front seats with a massage feature. The AT4X includes the same 16-way heated and ventilated power front seats with massage as standard content.
The F-250 counters with King Ranch's Kingsville Antique Affect leather and Platinum's power tailgate with a retractable step, which adds genuine day-to-day convenience for users who load the bed frequently. The F-250 Platinum also includes Pro Power Onboard at 2.0 kW as standard equipment, a useful feature for jobsite or campsite power needs.
For the F-250, bed length is listed at 6.75 feet and ground clearance at 8.7 inches.
The F-250 XLT also gains the new Carhartt Package for 2027, which adds Carhartt-branded interior cloth seating with triple-stitch construction, Carhartt all-weather floor mats, a spray-in bedliner with Carhartt branding, and 20-inch painted and machined aluminum wheels. It is an option for buyers who want a work-identity truck with practical interior details baked in.
Technology and Safety
The Sierra HD arrives with a significant display stack at upper trims: an available 13.4-inch Premium GMC Infotainment System, an available 12.3-inch digital Driver Information Center, and an available 15-inch multicolor Head-Up Display. The ProGrade Trailering System, available on SLT and above, includes an In-Vehicle Trailering App and up to 14 available camera views. Adaptive Cruise Control with trailering capability is standard on the Pro trim, making it available from the entry point of the lineup.
Sierra HD trailering technology
The F-250 matches the Sierra HD on infotainment screen size at Lariat and above with a 12-inch touchscreen, though it starts lower-resolution on XL and XLT at 8 inches. Wireless Apple CarPlay and Android Auto are standard on every F-250 trim, which is a noted advantage for buyers who make connectivity a baseline requirement.
Ford's technology stack at King Ranch includes a Head-Up Display, 12-inch cluster display, Intelligent Adaptive Cruise Control with Stop-and-Go and Speed Sign Recognition, Pro Trailer Backup Assist, and Blind-Spot Information System with Trailer Coverage. These features require moving up to King Ranch on the F-250 side.
On safety, both trucks include a Trailer Brake Controller as standard equipment at their base trim. The Sierra HD's eBoost system and segment-first electric power steering represent a structural advancement in braking and handling precision that does not have an F-250 equivalent. The F-250 covers Pre-Collision Assist with Automatic Emergency Braking as standard on XLT and above.
Value and Ownership
Both trucks carry an identical basic warranty of 3 years and 36,000 miles. The Sierra HD backs its powertrain with a 5-year/60,000-mile powertrain warranty. The F-250 matches that term on gas engines and extends diesel powertrain coverage further to 5 years and 100,000 miles, which remains a meaningful advantage for buyers who plan to run a diesel F-250 through high mileage.
The Sierra HD Pro comes with the Trailering Package, Trailering Mirrors, Trailer Brake Controller, and Adaptive Cruise Control with trailering capability as standard content, which means a working buyer does not need to option up simply to tow properly. The F-250 XL also includes a trailer brake controller as available equipment and provides a strong base for buyers on a work budget.
For diesel buyers focused on operating costs over time, the Sierra HD's 8.3L Duramax delivers the highest towing output in the class, which can translate to fewer trips and lower overall hauling costs on large loads. .
