The 2027 Silverado is finally here, but Chevy is still holding back some important numbers.
The truck arrives with updated styling, a completely redesigned interior, two next-generation V8 engines, an updated TurboMax four-cylinder, and the returning Duramax diesel. It also brings a revised trim lineup, larger screens across every model, and what Chevy calls its most powerful and advanced Silverado ever.
What Chevrolet did not reveal is just as interesting.
While we now know the truck will continue offering four powertrain choices and standard 10-speed automatic transmissions, Chevrolet has not released other key specifications buyers use when comparing trucks.
That leaves truck buyers with plenty of unanswered questions. Here are the five biggest things we still need to know before declaring the 2027 Silverado a winner.
Horsepower and Torque Remain a Mystery
This is the biggest unanswered question.
Chevrolet confirmed the outgoing 5.3-liter V8 and 6.2-liter V8 are being replaced by new 5.7-liter and 6.6-liter V8 engines, respectively. The company says the 2027 Silverado will offer the most powerful naturally aspirated V8 in the segment, but it has not released any horsepower or torque figures.
For reference, the 2026 Silverado lineup offers:
- 2.7L TurboMax: 310 hp, 430 lb-ft
- 5.3L V8: 355 hp, 383 lb-ft
- 6.2L V8: 420 hp, 460 lb-ft
- 3.0L Duramax Diesel: 305 hp, 495 lb-ft
Meanwhile, competitors already have established benchmarks:
Ford F-150
- 2.7L EcoBoost: 325 hp, 400 lb-ft
- 5.0L V8: 400 hp, 410 lb-ft
- 3.5L EcoBoost: 400 hp, 500 lb-ft
- 3.5L PowerBoost Hybrid: 430 hp, 570 lb-ft
Ram 1500
- 3.6L Pentastar V6: 305 hp, 369 lb-ft
- 3.0L Hurricane SO: 420 hp, 469 lb-ft
- 3.0L Hurricane HO: 540 hp, 521 lb-ft
- 5.7L HEMI V8: 395 hp, 410 lb-ft
Toyota Tundra
- 3.4L Twin-Turbo V6: 389 hp, 479 lb-ft
- i-FORCE MAX Hybrid: 437 hp, 583 lb-ft
If Chevrolet wants to claim leadership, these are the numbers it will have to beat. However, with the caveat of being the most powerful naturally aspirated V8, it really does not have much competition.
Payload and Towing Ratings Are Still Unknown
Chevrolet says the new engines were engineered to improve towing and capability, but official payload and towing ratings remain under wraps.
The outgoing 2026 Silverado provides a useful baseline:
- Maximum towing: 13,300 pounds
- Maximum payload: 2,260 pounds
Those figures already place the Silverado near the top of the segment, but competitors continue to push hard.
Ford F-150
- Maximum towing: 13,500 pounds
- Maximum payload: 2,440 pounds
Ram 1500
- Maximum towing: 11,610 pounds
- Maximum payload: 2,360 pounds
Toyota Tundra
- Maximum towing: 12,000 pounds
- Maximum payload: 1,850 pounds
Chevrolet repeatedly referenced improved torque and towing confidence during the reveal, which suggests these numbers could increase. The question is by how much. (All the numbers above are the maximum capacities claimed by each respective brand. Configurations may vary.)
Fuel Economy Could Be More Important Than Ever
Fuel economy matters even more today as truck prices continue to rise.
Unfortunately, Chevrolet has not released EPA estimates or projected fuel economy figures for any 2027 Silverado powertrain.
The current Silverado lineup offers respectable numbers, particularly with the Duramax diesel:
2026 Silverado
- 2.7L TurboMax: up to 20 mpg combined
- 5.3L V8: up to 18 mpg combined
- 6.2L V8: up to 17 mpg combined
- 3.0L Duramax: up to 25 mpg highway
Meanwhile, competitors have several strong fuel-economy plays:
Ford F-150
- PowerBoost Hybrid: up to 24 mpg combined
Ram 1500
- Standard Output Hurricane Inline-6: Up to 21 mpg combined
Toyota Tundra
- 3.4L Twin-Turbo V6: up to 22 mpg combined
- i-FORCE MAX Hybrid: up to 22 mpg combined
With GM introducing all-new V8 engines, one of the biggest questions is whether those engines can improve efficiency while maintaining traditional V8 performance. (All numbers above are provided by fueleconomy.gov)
How Large Is the Fuel Tank?
This may sound like a small detail, but truck owners know better.
Fuel tank size directly impacts driving range, towing convenience and how often owners stop at the pump.
The 2026 Silverado currently offers multiple tank sizes depending on configuration:
- 24-gallon tank
- 28-gallon tank
Chevrolet has not said whether those capacities will carry over to the 2027 truck.
Ford currently offers tanks up to 36 gallons in the F-150. Ram offers tanks up to 33 gallons in certain configurations, while Toyota has standard 32.2-gallon tanks in the Tundra.
Given how many Silverado owners tow boats, campers, and trailers long distances, this is one specification many buyers will be watching closely.
Off-Road Dimensions Could Change Significantly
Chevrolet spent considerable time discussing the Trail Boss and ZR2 during the reveal, yet it stopped short of providing complete off-road specifications. For buyers who spend weekends on trails, ranch roads, hunting leases, or job sites, those numbers matter just as much as towing capacity.
The current 2026 Silverado provides a baseline:
- Maximum ground clearance: 11.2 inches
- Maximum approach angle: 32.5 degrees
- Maximum breakover angle: 23.4 degrees
- Maximum departure angle: 23.4 degrees
Chevrolet confirmed the 2027 Silverado receives revised suspension tuning, updated chassis calibrations, and a new generation of ZR2 hardware, but exact dimensions remain unavailable. The company also highlighted improved off-road capability and trail performance throughout the launch presentation.
Competitors already provide strong benchmarks:
Ford F-150 Tremor
- Ground clearance: 9.4 inches
- Approach angle: 27.6 degrees
- Departure angle: 24.3 degrees
Ram 1500 Rebel
- Ground clearance: 10.8 inches
- Approach angle: 26.2 degrees
- Departure angle: 24.8 degrees
Toyota Tundra TRD Pro
- Ground clearance: 9 inches
- Approach angle: 23 degrees
- Departure angle: 23 degrees
The outgoing Silverado ZR2 already leads several competitors in approach angle, but Chevrolet’s decision to withhold the new measurements suggests there could be meaningful changes coming. Whether that means higher ground clearance, improved suspension travel, or better obstacle clearance remains one of the biggest unanswered questions for off-road enthusiasts.
Final Thoughts
The 2027 Chevy Silverado is not a dramatic visual reinvention, and that is probably by design. On the outside, this is an evolutionary update that keeps the Silverado’s familiar shape, stance and truck-first attitude intact. It still looks like a Silverado, just sharpened for the next generation.
The bigger story is inside and underneath.
The redesigned cabin appears to be a major step forward, especially compared with the outgoing Silverado’s interior, which has often lagged behind Ram and Ford in perceived refinement. Larger screens, a more modern layout, improved materials, and better trim separation should help Chevy close that gap in a big way.
But the unanswered numbers still matter. Horsepower, torque, towing, payload, fuel economy, fuel tank size, and off-road dimensions will determine how this truck stacks up where owners actually use it. The new Silverado may look familiar, but if Chevy delivers on capability, range, efficiency, and trail hardware, this could be a much bigger redesign than the exterior suggests.
