The four engines
| Engine | Horsepower | Torque | The read |
|---|---|---|---|
| 2.7L TurboMax I-4 (enhanced) | 350 hp | 455 lb-ft | The volume engine, carried over with enhancements — the torque figure embarrasses old small V8s. |
| 3.0L Duramax turbo-diesel I-6 | 305 hp | 495 lb-ft | The efficiency/towing cruiser. Highest torque per gallon in the lineup. |
| 5.7L V8 (all-new) | 402 hp | 428 lb-ft | Replaces the long-serving 5.3L. The new mainstream V8. |
| 6.6L V8 (all-new) | 481 hp | 501 lb-ft | The headline: the most powerful Silverado ever, and the most powerful naturally-aspirated V8 in the class. Replaces the 6.2L. |
Manufacturer ratings per GM's announcement; EPA fuel-economy figures publish closer to on-sale. Max towing: 13,700 lb.
What the new generation means for buyers
The 5.3L and 6.2L V8s retire with the outgoing truck, which makes 2026 the last model year for the proven V8 pair — and the best discount window. Generation changeovers are the single strongest lever on the outgoing model: dealers clear 2026 stock as 2027s land. If the 481-hp 6.6L or max towing is the goal, wait for the 2027; if the goal is the most truck per dollar, the 2026 clearance is where the deals live.

Frequently asked questions
What engines does the 2027 Silverado 1500 have?
Four, per GM's official announcement: an enhanced 2.7L TurboMax four-cylinder (350 hp / 455 lb-ft), the 3.0L Duramax turbo-diesel (305 hp / 495 lb-ft), an all-new 5.7L V8 (402 hp / 428 lb-ft) replacing the 5.3L, and an all-new 6.6L V8 (481 hp / 501 lb-ft) replacing the 6.2L. Maximum towing is rated at 13,700 pounds.
Is the 2027 Silverado the most powerful ever?
Yes — GM bills the next-generation 2027 Silverado 1500 as the most powerful Silverado ever, led by the new 6.6L V8's 481 hp and 501 lb-ft, which Chevrolet positions as the most powerful naturally-aspirated V8 in the segment.
What happened to the 5.3L and 6.2L V8s?
They retire with the outgoing generation: the new 5.7L V8 takes the 5.3L's mainstream slot and the 6.6L V8 takes the 6.2L's performance slot. That makes 2026 the final model year for the old V8 pair — relevant if you prefer the proven engines or want the clearance discount on them.
Should I buy a 2026 Silverado now or wait for the 2027?
The honest math: a generation change is the single best discount lever on the outgoing truck. As 2027s arrive, dealers get aggressive on remaining 2026 stock — check what buyers are actually paying for 2026 Silverados and the live lease programs before deciding. If you want the new 6.6L V8 or maximum towing, wait; if you want maximum discount on a proven truck, the clearance window is the play.
