The 2027 Chevrolet Silverado 1500 offers four engines, with the 6.6L V8 producing 481 hp and 501 lb-ft of torque. That makes it the most powerful Silverado 1500 ever built, while the 5.7L V8 leads with 13,700 lbs of max available towing. This page breaks down every engine option and what each one delivers, with inventory available at Greg Hubler Chevrolet.
Chevrolet introduced its first V8 in 1955. Seventy years later, the 2027 Silverado 1500 carries that legacy into its most capable generation yet. The next-generation lineup includes two all-new, American-assembled V8 engines, an upgraded TurboMax I4, and the class-exclusive Duramax 3.0L Turbo-Diesel. Every engine pairs with a 10-speed automatic transmission, so the foundation is consistent regardless of which powertrain you choose.
What changes across the four engines is the performance profile: raw power, maximum towing, maximum payload, and fuel type. Choosing the right engine is the most consequential decision you make when configuring a new Silverado 1500, and the differences between them are meaningful.
The 6.6L V8 is the top of the lineup in outright horsepower. It produces 481 max available horsepower and 501 lb-ft of max available torque, numbers that define it as the most powerful engine ever offered in a Silverado 1500. Max available towing reaches 9,700 lbs and max available payload sits at 1,510 lbs. This engine is designed for buyers who prioritize raw, confident power over maximum towing efficiency, and it delivers both with room to spare.
The 5.7L V8 is the tow-focused choice. It produces 402 max available horsepower and 428 lb-ft of max available torque, but the headline figure is its 13,700 lbs of max available towing, which Chevrolet claims as best-in-class available towing. Max available payload reaches 2,170 lbs. For buyers who regularly haul heavy loads, whether boats near the lakes around Camby or equipment trailers across Indiana, this is the engine engineered specifically for that job.
The TurboMax is the turbocharged four-cylinder option and it earns its own headline: best-in-class standard torque. It delivers 350 hp and 455 lb-ft of torque, with 9,400 lbs of max available towing and 2,340 lbs of max available payload. The 2,340-lb payload figure is the highest of any engine in the lineup, which matters for buyers loading down the bed with materials and equipment rather than pulling a trailer. The TurboMax is also the standard engine on several trims, making it the entry point for a significant portion of the Silverado range.
The Duramax 3.0L Turbo-Diesel holds a unique position: it is the only diesel engine available in the light-duty half-ton segment. It produces 305 max available horsepower and 495 lb-ft of max available torque, with 12,000 lbs of max available towing and 1,870 lbs of max available payload. Diesel torque delivery is different from gasoline engines, with peak torque arriving low in the RPM range for a pulling sensation that feels authoritative from the moment you load the trailer. For long-distance hauling or steady highway work, the Duramax diesel remains a compelling option.
Both V8s are reimagined from the ground up and assembled in America, building directly on Chevrolet’s seven-decade V8 tradition.
| Engine | Horsepower | Torque | Max Available Towing | Max Available Payload |
|---|---|---|---|---|
| 6.6L V8 | 481 hp | 501 lb-ft | 9,700 lbs | 1,510 lbs |
| 5.7L V8 | 402 hp | 428 lb-ft | 13,700 lbs | 2,170 lbs |
| 2.7L TurboMax I4 | 350 hp | 455 lb-ft | 9,400 lbs | 2,340 lbs |
| 3.0L Duramax Turbo-Diesel I6 | 305 hp | 495 lb-ft | 12,000 lbs | 1,870 lbs |
The 2027 Silverado 1500 is available in seven trims: Work Truck, WT, Custom, Silverado, Custom Trail Boss, Trail Boss, ZR2, and High Country. Not every engine is available on every trim, and Chevrolet has not yet announced complete per-trim engine assignments for the 2027 model year. Specific powertrain-to-trim pairings will be available when full ordering information is released.
What Chevrolet has announced across the lineup: all four engines use the same 10-speed automatic transmission, all trims include the 16.3-inch center touchscreen and 12.2-inch digital driver information center, and Super Cruise hands-free driver assistance with trailering capability is available across more of the lineup than ever before.
The ZR2 and High Country sit at the top of the range and are expected to offer the broadest powertrain selections. The WT and Custom represent the working end of the lineup, built for buyers who need straightforward capability on the job site.
A number like 13,700 lbs of towing is not just a spec sheet figure. It means the 5.7L V8 can pull a fully loaded fifth-wheel camper, a heavy equipment trailer, or a dual-axle boat rig without strain. Indiana buyers who work in agriculture, construction, or landscaping, whether in Camby or anywhere across the state, will find the towing and payload numbers directly relevant to their workday.
The 6.6L V8 appeals to a different kind of driver: one who wants the most powerful truck available, full stop. The 481-hp ceiling provides a performance margin that shows up during on-ramp merges, when passing on the highway, or when the terrain gets demanding.
The TurboMax I4 makes sense for buyers whose primary concern is payload capacity. At 2,340 lbs of max available payload, it actually outperforms the V8s in that category, which surprises most buyers at first. If the bed is carrying weight rather than a hitch pulling weight, the TurboMax delivers.
The Duramax diesel earns its place for buyers putting highway miles on the truck. The torque profile and efficiency characteristics of the diesel make long-haul trips and sustained towing feel less taxing on the drivetrain.
Super Cruise, the segment-exclusive hands-free trailering system, works in conjunction with whichever engine you choose. Drivers have logged more than a billion hands-free miles using Super Cruise technology. Adding that capability to a truck already engineered for serious towing creates a genuinely different experience on long interstate hauls.
No other light-duty half-ton pickup offers a diesel engine. The Duramax 3.0L is a segment-exclusive option that gives Silverado buyers a choice competitors simply cannot match. Most rival trucks offer two or three engines; the Silverado offers four distinct powertrains, each with a defined performance profile.
The best-in-class available towing claim for the 5.7L V8 at 13,700 lbs is another differentiator. While specific competitor specs are not independently verified here, Chevrolet’s towing claim positions the 5.7L V8 above what equivalent half-ton rivals achieve in the same category.

The breadth of the four-engine lineup is itself a competitive advantage. Buyers are not choosing between a base engine and an upgrade. They are choosing between four purpose-built powertrains, each optimized for a different kind of use.
The 2027 Chevrolet Silverado 1500 is available late 2026. Greg Hubler Chevrolet serves buyers across Camby and throughout central Indiana, and the Silverado lineup will be available to explore at the store when it arrives. Whether the 5.7L V8’s best-in-class towing, the 6.6L V8’s 481-hp ceiling, the TurboMax’s payload advantage, or the diesel’s unique torque delivery fits your work best, the Silverado has an engine built for it. Check current inventory and get in line for updates when the 2027 model opens for orders.
