2027 Chevrolet Silverado 1500
2027 Silverado 1500 Specs and Dimensions PA
The 2027 Silverado 1500 specifications separate engine output, cab dimensions and bed capacity for Allentown drivers balancing passenger room and truck space.
The 2027 Silverado 1500 combines a ten-speed automatic with engines ranging from the 350-hp TurboMax to the 481-hp 6.6L V8. Body choice matters just as much on MacArthur Road or a Bethlehem side street: a Regular Cab and a Crew Cab put their length into different kinds of usable space. The Silverado overview covers the lineup, and the trim comparison separates equipment packages.
Key Numbers
- The Silverado TurboMax produces 350 hp and 455 lb-ft of torque.
- A Silverado Standard Bed cargo box holds 71.7 cubic feet.
- The Silverado front brake rotors measure 13.5 inches.
- Double Cab and Crew Cab Silverado trucks offer an approximately 34-gallon fuel tank.
Engine Specifications
| Engine | Horsepower | Torque | Transmission |
|---|---|---|---|
| 2.7L TurboMax | 350 hp | 455 lb-ft | 10-speed automatic |
| 5.7L V8 | 402 hp | 428 lb-ft | 10-speed automatic |
| 6.6L V8 | 481 hp | 501 lb-ft | 10-speed automatic |
| 3.0L Duramax Turbo-Diesel | 305 hp | 495 lb-ft | 10-speed automatic |
The 5.7L V8 and 6.6L V8 use both port and direct fuel injection. The Duramax reaches its 495 lb-ft torque rating at 2,750 rpm; TurboMax reaches 455 lb-ft at 3,000 rpm. Torque delivery, fuel type and the body combination create different uses for the four engines.
Exterior Dimensions by Cab and Bed
The examples below are GM’s two-wheel-drive body dimensions. Lifted models, different beds and equipment change height, clearance and weight. The width shown is body width without mirrors, so it describes the body rather than a mirror-to-mirror garage opening.
| 2WD body example | Length | Wheelbase | Body width / height |
|---|---|---|---|
| Regular Cab Standard Bed | 212.12 inches | 126.49 inches | 81.20 / 75.55 inches |
| Double Cab Standard Bed | 233.14 inches | 147.44 inches | 81.20 / 75.35 inches |
| Crew Cab Short Bed | 233.07 inches | 147.44 inches | 81.20 / 75.50 inches |
| 2WD body example | Ground clearance | Turning diameter |
|---|---|---|
| Regular Cab Standard Bed | 7.32 inches | 40.7 feet |
| Double Cab Standard Bed | 7.26 inches | 46.3 feet |
| Crew Cab Short Bed | 7.38 inches | 46.3 feet |
Double Cab Standard Bed and Crew Cab Short Bed have almost the same overall length in these examples. Crew Cab spends more of that length on rear passenger room; Double Cab pairs its shorter rear cabin with the longer cargo box. That distinction matters for a Whitehall driver carrying adults and tools on the same trip.

Interior Dimensions and Seating
| 2WD body example | Front legroom | Rear legroom | Front headroom |
|---|---|---|---|
| Regular Cab Standard Bed | 44.37 inches | Single-row cab | 43.18 inches |
| Double Cab Standard Bed | 44.37 inches | 34.75 inches | 42.67 inches |
| Crew Cab Short Bed | 44.37 inches | 42.80 inches | 43.07 inches |
GM lists three seating positions for the Regular Cab and up to six with an eligible bench-seat Double Cab or Crew Cab. Front bucket seats change that count. Crew Cab rear legroom is 42.80 inches in the example above, giving adult passengers more space than the Double Cab’s rear row.
Capacity and Capability
| Item | Exact configuration | Figure |
|---|---|---|
| Cargo-box volume | Crew Cab Short Bed | 62.8 cubic feet |
| Cargo-box volume | Standard Bed | 71.7 cubic feet |
| Inside bed length | 2WD Standard Bed example | 79.68 inches |
| Width between wheelhouses | 2WD Standard Bed example | 50.62 inches |
| Curb weight | TurboMax Regular Cab Standard Bed 2WD | 4,560 pounds |
| GVWR | Regular Cab Standard Bed 2WD | 6,900 pounds |
| Available fuel tank | Regular Cab | Approximately 28 gallons |
| Available fuel tank | Double Cab or Crew Cab | Approximately 34 gallons |
Properly equipped, a 5.7L V8 Double Cab Standard Bed 2WD with Max Trailering Package tows up to 13,700 lbs. The full towing page separates that maximum from the other engine and cab ratings. Curb weight is the empty truck’s weight; GVWR is its rated loaded limit.
Wheels, Tires and Brakes
Custom uses 20-inch wheels; Custom Trail Boss and Trail Boss use 18-inch wheels with 34-inch MT tires. High Country has 22-inch wheels, and ZR2 combines 18-inch wheels with 35-inch MT tires.
| Brake component | Diameter |
|---|---|
| Front vented rotor | 13.5 inches |
| Rear vented rotor | 13.6 inches |
Fuel Economy by Engine and Drive System
The EPA ratings separate ordinary 4WD trucks from mud-terrain-tire and ZR2 versions. These are city/highway/combined estimates, not fuel consumption while towing. Wheel, tire, road, load and driving conditions affect actual results.
| EPA configuration | City / highway / combined MPG |
|---|---|
| 5.7L Silverado 2WD | 15 / 19 / 17 |
| 5.7L Silverado 4WD | 15 / 18 / 16 |
| 3.0L diesel Silverado 2WD | 22 / 27 / 24 |
| 3.0L diesel Silverado 4WD | 21 / 23 / 22 |
| 6.6L Silverado 4WD | 14 / 18 / 15 |
| 3.0L diesel Silverado 4WD ZR2 | 20 / 22 / 21 |
| 6.6L Silverado 4WD ZR2 | 13 / 15 / 14 |

Key Features by Trim
| Feature | Standard equipment | Available equipment |
|---|---|---|
| 16.3-inch center screen | Every trim | Included throughout |
| 12.2-inch driver display | Every trim | Included throughout |
| 11.5-inch passenger screen | High Country and ZR2 | Included on the listed premium trims |
| Panoramic sunroof | High Country | Silverado, Trail Boss and ZR2 |

Safety and Driver Assistance
Chevrolet lists adaptive cruise control, Intersection Automatic Emergency Braking, Front and Rear Park Assist and Blind Zone Steering Assist in the standard assistance equipment. The manufacturer’s feature information explains the equipment. Driver assistance requires an attentive driver; compatible roads, an active plan and system conditions apply to Super Cruise.
Warranty Coverage
| Coverage | Chevrolet’s published term |
|---|---|
| Bumper-to-bumper | 3 years / 36,000 miles, whichever comes first |
| Typical gasoline powertrain | 5 years / 60,000 miles, whichever comes first; other durations apply |
| Typical rust-through | 6 years / 100,000 miles, whichever comes first; other durations apply |
| First maintenance visit | Within one year of delivery at a participating dealer, subject to restrictions |
Chevrolet warranty details distinguish defects coverage from scheduled upkeep. The engine-specific warranty booklet governs powertrain coverage. Silverado service intervals cover the separate tire, oil, filter and fluid schedule for a truck driven around Emmaus, Nazareth or Slatington.
Silverado Dimensions in Practice
| Daily use | Body difference that matters |
|---|---|
| A tighter parking turn | The Regular Cab example turns in 40.7 feet, versus 46.3 feet for the longer examples |
| Adults in the rear row | Crew Cab has 42.80 inches of rear legroom in the listed example |
| Long equipment in the bed | The Standard Bed example has 79.68 inches of inside floor length |
| A commuting truck with weekend cargo | Crew Cab Short Bed combines the larger rear cabin with 62.8 cubic feet of cargo-box volume |
For Easton parking and family travel, the cab and bed choice changes the truck more directly than a wheel-style choice. Shop Silverado 1500 inventory by the body and engine that fit the job, or return to the buyers guide.
Silverado Specifications FAQs
How long is a 2027 Silverado Crew Cab Short Bed?
The two-wheel-drive Crew Cab Short Bed example measures 233.07 inches long, with a 147.44-inch wheelbase. That combination uses a full rear cabin and a shorter bed; a different bed or drive system changes the relevant dimensions and weights.
What is the Silverado body width without mirrors?
GM’s engineering order guide lists 81.20 inches of body width without mirrors for the body examples shown here. That measurement excludes the mirrors. The Regular Cab, Double Cab and Crew Cab examples share this body-width figure while their overall length, height and turning diameter differ.
How much rear legroom does a Crew Cab provide?
The listed Crew Cab Short Bed example has 42.80 inches of rear legroom, compared with 34.75 inches in the Double Cab Standard Bed example. Both have 44.37 inches of front legroom. Crew Cab therefore puts more of its overall length into the space behind the front seats.
What is the Silverado Standard Bed floor length?
The Standard Bed examples have an inside floor length of 79.68 inches. Their width between wheelhouses is 50.62 inches, and cargo-box volume is 71.7 cubic feet. These dimensions describe the cargo box itself; the Regular Cab and Double Cab versions have different passenger-space layouts.
What wheel and tire sizes come on ZR2?
The ZR2 pairs 18-inch wheels with 35-inch MT tires. It also has a 2-inch factory lift, front and rear e-lockers and Multimatic DSSV dampers. Those tire and suspension choices distinguish its physical setup from the 34-inch-tire Trail Boss models and the 22-inch-wheel High Country.
What is the difference between Silverado curb weight and GVWR?
Curb weight describes the unloaded truck; GVWR is the maximum rated weight of the loaded truck. Chevrolet lists 4,560 pounds of curb weight for a TurboMax Regular Cab Standard Bed 2WD example. Its body’s published GVWR is 6,900 pounds, with equipment and actual loading affecting the available margin.
Which EPA rating belongs to the diesel Silverado 4WD?
The 3.0L diesel Silverado 4WD is EPA-rated at 21 city, 23 highway and 22 combined MPG. The separate diesel ZR2 rating is 20 city, 22 highway and 21 combined MPG. These ratings distinguish the ordinary 4WD and ZR2 configurations and do not describe fuel consumption while towing.
