What’s New Under the Hood? All Four Engines in the 2027 Chevrolet Silverado 1500

The 2027 Chevrolet Silverado 1500 shows up with four engines, and the tow chart reads backwards. The most powerful gas engine in the lineup does NOT tow the most. Order on horsepower alone and you might drive off with the wrong truck for your work. Here’s the straight breakdown so you can order with confidence.

Which 2027 Silverado Engine Is the Sweet Spot for Most Buyers?

For most buyers across northeastern South Dakota, the farmers, ranchers, and tradespeople who need a truck that earns its keep every day, the 5.7L V8 is the engine we’d put in front of you first, though the TurboMax earns a real second look before you commit. Chevrolet lists it at 402 hp and 428 lb-ft of torque, and with the right equipment it carries the lineup’s top tow rating of 13,700 lbs. That figure is 400 more lbs than the outgoing 2026 Silverado’s best tow number, and Chevrolet calls it best-in-class.

Need the strongest payload number in the family? The TurboMax delivers it, and it’s a genuine second look and no afterthought. At 350 hp and 455 lb-ft, it actually out-torques the 5.7L at low rpm, and Chevrolet rates it for up to 2,340 lbs of payload, the best payload figure in the four-engine lineup. If you’re running grain bags, tool boxes, and equipment in the bed more than you’re hooking up a gooseneck, that number matters more than a tow rating you may never reach.

Which Engine Should You Watch Out For?

Keep a close eye on the 6.6L V8 before you order it, because the most powerful gas engine in the lineup carries one of the lower tow ratings, and if you shop by horsepower alone you can end up with less trailer capability than you expected. None of this is a knock on the engine. At 481 hp and 501 lb-ft it’s the most powerful naturally aspirated V8 Chevrolet has ever offered in a half-ton, and that claim is legitimate. But Chevrolet’s published max tow rating for the 6.6L is 9,700 lbs. The 5.7L, a less powerful engine, is rated to tow 4,000 more pounds. The gap exists because tow ratings are set by a combination of engine, cab configuration, drivetrain, and axle ratio, and the 6.6L is offered only in a crew cab 4WD configuration where those variables produce a lower ceiling. If you order the 6.6L expecting the biggest tow number, you’ll be disappointed.

Order it because you want the most horsepower and torque in the lineup. The 6.6L and the 5.7L are two different trucks.

The same logic applies to the Duramax diesel for buyers who haven’t looked at one since the early DEF-equipment years. The 3.0L Duramax is a clean, refined inline-six. At 305 hp and 495 lb-ft of torque it tows up to 12,000 lbs when equipped for it, and with the available 34-gallon tank Chevrolet projects over 900 miles of highway range on a single fill. US-81 runs south from Watertown to Sioux Falls. For a run down US-81 to Sioux Falls and back with a loaded trailer, that range matters, and a heavy bed load isn’t what this engine was built for.

The tradeoff is payload. The Duramax tops out at 1,870 lbs, below both V8 options and well below the TurboMax.

Which 2027 Silverado Engine Fits Your Work?

The honest short version is that your use case picks the engine, not the other way around, so sort out how you actually work the truck before you fall for a horsepower headline or a tow number you’ll never test.

You haul more than you tow. Go with the TurboMax. The 2,340-lb payload rating leads the lineup, and this engine is standard on the Work Truck trim, which keeps the out-the-door number accessible. Chevrolet also put it on the lowest trim for a reason.

You pull heavy equipment on a regular basis. The 5.7L V8 is your engine. Its 13,700-lb max tow rating, with the trailering gear in place, is the number that supports a loaded horse trailer, a two-axle equipment trailer, or a grain wagon on a section-line gravel road in any season. For the heavy farm and ranch towing common around Codington County, that’s the number we trust.

You want the most truck the 1500 platform can deliver, and towing the absolute maximum is not your daily task. Then the 6.6L V8 is genuinely compelling, and no half-ton Chevrolet has ever made more power. Just go in knowing the 9,700-lb tow ceiling and size your trailer needs accordingly.

You drive long miles on the highway and pull a consistent load. The Duramax diesel with the large tank makes over 900 miles between fuel stops by Chevrolet’s estimate, and its 495 lb-ft of torque moves a trailer at a steady cruise without working the engine hard. The long-haul argument for diesel has always been true, and it still holds.

All four pair with the same 10-speed automatic, which is the one transmission Chevrolet is offering across the entire 2027 lineup. No more choosing between an eight-speed and a ten-speed depending on which engine you picked.
