Engine Specifications

Four powertrains carry the 2027 Silverado 1500, each paired with a 10-speed automatic transmission. Two are brand-new small-block V8s.

Engine	Type	Transmission	Notes
2.7L TurboMax	Turbocharged inline-4	10-speed automatic	350 hp, 455 lb-ft; standard on the Work Truck; now on the 10-speed
5.7L V8	Next-gen small-block V8	10-speed automatic	402 hp, 428 lb-ft; replaces the prior 5.3L; standard on High Country
6.6L V8	Next-gen small-block V8	10-speed automatic	481 hp, 501 lb-ft; the most powerful naturally-aspirated V8 in the class
Duramax 3.0L Turbo-Diesel	Turbo-diesel inline-6	10-speed automatic	305 hp, 495 lb-ft; segment-exclusive diesel; standard on ZR2, available on Work Truck and High Country

TurboMax's 350-horsepower output is 40 above its predecessor, while both gas V8s combine port and direct injection; compare the different engine choices against how your Silverado will work along I-49.

Capacity and Capability

A properly equipped 5.7L Double Cab 2WD with Max Trailering reaches a 13,700-pound maximum. Properly equipped Duramax trucks reach 12,000 pounds. The 6.6L V8 reaches 9,700 pounds with the required equipment. TurboMax reaches 9,400 pounds properly equipped. Match your loaded trailer with the selected truck’s actual rating at Nunnally. TurboMax supplies the properly equipped 2,340-pound payload maximum, a separate consideration from the trailer rating when counting people and bed cargo. Added cooling capacity comes with Max Trailering, while compatible-road Super Cruise can assist during towing; discuss those separate equipment functions at Nunnally when configuring for sustained interstate travel. Full detail is on the 2027 Silverado 1500 towing guide; heavy gooseneck and fifth-wheel loads are better matched to the Silverado 2500HD.

Wheels, Tires and Brakes

Trim	Wheels / tires
Custom	20-inch Technical Gray machine-faced
Custom Trail Boss	34-inch MT tires on 18-inch Dark Android wheels, 2-inch lift
Trail Boss	34-inch MT tires on 18-inch Dark Android wheels, 2-inch lift
ZR2	35-inch MT tires on 18-inch diamond-cut wheels; front and rear e-lockers
ZR2 Bison	18-inch beadlock-capable, full skid plates
High Country	22-inch After Midnight machine-faced

Wheel diameters run from 17 to 22 inches by trim, with vented brake rotors 13.5 inches in front and 13.6 inches in the rear. ZR2 pairs its 35-inch tires with Multimatic DSSV dampers and jounce dampers for high-speed off-road control.

Fuel Economy and Range

The available 34-gallon fuel tank goes on Double Cab and Crew Cab trucks (the Regular Cab option is 28 gallons), and it is standard on the ZR2. Paired with the 3.0L Duramax, it gives a highway driving range of over 900 miles, enough for a long I-49 haul or a run out US-62 without a fuel stop.

Key Features by Trim

The features most buyers cross-shop, by trim. Read S as included equipment and O as an option; a "not std" entry means you should check the actual Silverado's configuration at Nunnally rather than assume the feature is fitted.

In Practice: Reading the 2027 Silverado 1500 Spec Sheet

For Northwest Arkansas buyers, three numbers matter most: the diesel's highway range of over 900 miles for long I-49 hauls and trips out US-62, the 6.6L V8's 481 horsepower if you want maximum gas power, and each engine's tow rating if you pull a boat to the Beaver Lake ramps. The 5.7L V8's 13,700 pounds is the top rating, and the Duramax follows at 12,000. Beyond the numbers, pick cab and bed for how you load, trim for how you live in the truck, and engine for whether you value the diesel's range or a V8's character.

2027 Silverado 1500 Specs FAQs

What engines does the 2027 Silverado 1500 offer?

The four choices are a 2.7-liter TurboMax four-cylinder, 5.7-liter and 6.6-liter gas V8s, and a 3.0-liter Duramax diesel, each with ten automatic ratios; compare them at Nunnally using your loaded trailer and daily driving distance, because horsepower alone does not identify the best towing configuration.

How much horsepower does the 2027 Silverado 1500 have?

Rated output is 350 horsepower for TurboMax, 402 for the smaller V8, 481 for the larger V8 and 305 for Duramax, giving Nunnally shoppers four different engine priorities. The 6.6L leads this group on naturally aspirated gas power, while the highest trailer rating belongs to a different engine-and-cab combination.

What is the 2027 Silverado 1500's towing capacity?

A properly equipped 5.7L Double Cab 2WD with Max Trailering reaches 13,700 pounds. Properly equipped Duramax trucks reach 12,000 pounds. The 6.6L V8 reaches 9,700 pounds with the required equipment. TurboMax reaches 9,400 pounds properly equipped. Check the selected truck’s configuration against your loaded trailer rather than using another engine’s maximum.

What does the 2027 Silverado 1500 weigh?

Curb weight runs from 4,560 pounds for the 2.7L Regular Cab in 2WD to 6,140 pounds for the Duramax Crew Cab 4WD ZR2. The body offers Regular, Double and Crew cabs with short, standard and long beds.

What is the biggest screen in the 2027 Silverado 1500?

A standard 16.3-inch center touchscreen, with a 12.2-inch driver information center standard and an 11.5-inch passenger screen on ZR2 and High Country — over 60 inches of digital displays.

How far can a diesel 2027 Silverado 1500 go on a tank?

More than 900 highway miles is the Duramax figure when paired with the available 34-gallon tank; compare that combination against your longer interstate routes with Nunnally, keeping highway range distinct from the fuel consumption you would experience while towing a trailer through Ozark grades.
