2027 Chevy Silverado 1500 Order Guide: Which Engine Every Trim Gets, and Why the Base Truck Wins Big
Chevrolet’s next-generation Silverado 1500 has been public since the brand revealed the redesigned truck in June. However, the details that actually matter at the dealership live in the order guide. Now that the 2027 Silverado 1500 order guide is live, we know exactly which of the 2027 Silverado engines comes standard on each trim, what you can upgrade to, and where the fine print will steer your purchase.
In short, every gas engine got stronger, and every engine now pairs with a 10-speed automatic. On top of that, the least expensive Silverado you can buy is a far better truck than it was a year ago. Here’s what the typical buyer needs to know.
The 2027 Silverado Engine Lineup at a Glance
The 2027 Silverado 1500 offers four engines. In fact, two of them are brand new sixth-generation small-block V8s that replace the outgoing 5.3-liter and 6.2-liter V8s.
| Engine | Horsepower | Torque | Transmission | 2026 Equivalent |
|---|---|---|---|---|
| 2.7L TurboMax I4 | 350 hp @ 5,200 RPM | 455 lb-ft @ 3,000 RPM | 10-speed automatic | 310 hp / 430 lb-ft |
| 5.7L V8 | 402 hp @ 5,500 RPM | 428 lb-ft @ 4,300 RPM | 10-speed automatic | 5.3L V8: 355 hp / 383 lb-ft |
| 6.6L V8 | 481 hp @ 5,800 RPM | 501 lb-ft @ 4,000 RPM | 10-speed automatic | 6.2L V8: 420 hp / 460 lb-ft |
| 3.0L Duramax Turbo-Diesel I6 | 305 hp @ 3,750 RPM | 495 lb-ft @ 2,750 RPM | 10-speed automatic | Unchanged |
Overall, the gains are real. First, the TurboMax picks up 40 horsepower and 25 lb-ft. The new 5.7-liter V8 also makes 47 more horsepower and 45 more lb-ft than the 5.3-liter it replaces. At the top, the 6.6-liter V8 adds 61 horsepower and 41 lb-ft over the old 6.2-liter, and Chevrolet says it’s the most powerful naturally aspirated V8 in the segment. Meanwhile, the Duramax diesel carries over with the same output. It also remains the only diesel you can get in a half-ton pickup from any automaker.
Which Engine Comes Standard on Each 2027 Silverado Trim
This is where the order guide earns its keep. The 2027 lineup includes seven retail trims. In addition, the Silverado trim itself comes in two configurations (1LT and 2FL), so there are eight versions to choose from. Here’s the full breakdown.
| Trim | Starting Price (incl. destination) | Standard Engine | Available Engines |
|---|---|---|---|
| Work Truck | $41,395 | 2.7L TurboMax | 5.7L V8, 3.0L Duramax |
| Custom | $46,395 | 2.7L TurboMax | None |
| Silverado (1LT) | $50,695 | 2.7L TurboMax | 5.7L V8, 3.0L Duramax |
| Silverado (2FL) | N/A | 2.7L TurboMax | None |
| Custom Trail Boss | $57,195 | 2.7L TurboMax | 5.7L V8, 3.0L Duramax |
| Trail Boss | $63,995 | 2.7L TurboMax | 5.7L V8, 3.0L Duramax |
| High Country | $74,495 | 5.7L V8 | 6.6L V8, 3.0L Duramax |
| ZR2 | $79,995 | 3.0L Duramax | 6.6L V8 |
What Stands Out in the Order Guide
A few things jump out.
The TurboMax is the backbone of the lineup. It’s standard on six of the eight configurations. In fact, if you shop Custom or the 2FL version of the Silverado trim, it’s your only choice. Also, the 2FL is a retail-only package that pairs the TurboMax with the Z71 Off-Road Package on 4WD Crew Cab short bed and 4WD Double Cab models.
The 6.6L V8 lives at the top of the ladder. Specifically, only High Country and ZR2 buyers can get the most powerful engine, and the order guide says it requires 4WD. Therefore, if you want the big V8 in a Trail Boss, you’re out of luck.
The ZR2 goes diesel first. Instead of a gas V8, Chevrolet made the Duramax the ZR2’s standard engine, with the 6.6-liter V8 as the upgrade. That’s a smart fit for an off-road truck because the diesel’s 495 lb-ft arrives at just 2,750 RPM, right where you want it when crawling over rocks.

The High Country gets the new 5.7L standard. Luxury truck buyers get the 402-horsepower V8 without checking an option box. They can also step up to either the 6.6-liter V8 or the diesel.
The Fine Print That Could Shape Your Purchase
Order guides are full of footnotes, and several tied to the 2027 Silverado engines will directly affect what you see on dealer lots.
- The Duramax requires a Crew Cab. As a result, Regular Cab and Double Cab buyers can only get gas engines.
- The 5.7L V8 skips the Regular Cab standard bed. On the Work Truck, the V8 also requires the WT Convenience Package.
- The TurboMax can’t get the bigger fuel tank. The optional 34-gallon tank isn’t available with the TurboMax or on Regular Cab models, but it comes standard with the 6.6-liter V8. So if you road trip or tow often, that range difference matters.
- Axle ratios depend on the engine. Every TurboMax truck gets a 3.42 rear axle, whereas V8 and diesel trucks use a 3.23 ratio.
- Late availability is everywhere. The order guide flags the TurboMax engine, all Work Truck models, all Regular Cab and Double Cab models, and Crew Cab standard bed models as late availability. Because of that, early inventory could lean toward pricier V8 and diesel Crew Cab short beds, so budget buyers may need patience or a factory order.
- Automatic stop/start comes standard across the lineup, with a disable switch.
How Much Can It Tow?
Chevrolet says a properly equipped 5.7-liter Crew Cab can pull up to 13,600 pounds, while a 2WD Double Cab with the same setup tops the lineup at 13,700 pounds. Meanwhile, the Duramax tops out at 12,000 pounds in 4WD Crew Cab form with the Max Trailering Package. According to the order guide, that package comes only on the Silverado (1LT) trim and requires either the 5.7-liter V8 or the diesel.
2027 vs. 2026 Silverado: What Changes for the Typical Buyer
Beyond the engines, the 2027 Silverado reshuffles the lineup. For example, the 2026 truck’s RST and LTZ trims don’t appear in the 2027 order guide. Similarly, the LT now simply goes by Silverado, and the LT Trail Boss becomes the Trail Boss. Overall, that’s a cleaner ladder with fewer overlapping choices, which should make shopping easier. GM also dropped leather seating from every 2027 Silverado, a change we broke down in our story on the leather-free cabins.
Still, the bigger story for everyday buyers is how much more comes standard, even on the Work Truck:
- A full safety suite on every trim. Silverado Active Safety is standard from the Work Truck up, including adaptive cruise control, Enhanced Automatic Emergency Braking, Intersection Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Reverse Automatic Braking, Rear Cross Traffic Braking, Blind Zone Steering Assist, and front and rear park assist.
- Big screens everywhere. Chevrolet says a 16.3-inch center touchscreen and a 12.2-inch digital driver display are standard across the lineup.
- Towing basics included. Every 2027 Silverado gets the trailering package with hitch and 7-pin and 4-pin connectors, plus an integrated trailer brake controller.
- Teen Driver is standard. For families handing the keys to a new driver, that’s a nice touch at every price point.
Next, step up to the Custom and you add remote start, a power driver seat, a 400-watt 120-volt bed outlet, LED cargo bed lighting, Hitch View, and an EZ Lift tailgate with power lock and release. At the top, the ZR2 and High Country get Super Cruise hands-free driver assistance as standard. In addition, Chevrolet says Super Cruise now works while trailering, a segment first.
Final Thoughts: Which Trim Makes the Most Sense?
For most buyers, the sweet spot looks like the Silverado (1LT) trim. It starts at $50,695 and comes standard with a TurboMax that now makes 350 horsepower. It also unlocks both the 5.7-liter V8 and the Duramax, plus the Max Trailering Package if you tow heavy. In other words, if you want a V8 without the High Country price, this is the trim to build.
On the other hand, if you mostly commute and haul the occasional load, the standard TurboMax is more than enough truck. Its 455 lb-ft of torque arrives at just 3,000 RPM, so it feels strong around town. Even so, watch that fuel tank restriction if you drive long distances.
Of course, if you want the headline engine, be ready to pay for it. Of all the 2027 Silverado engines, the 6.6-liter V8 is the one you’ll only find in trims starting at $74,495. Cross-shopping the GMC twin? See our breakdown of the 2027 GMC Sierra 1500 specs and pricing.
