Chevy kills its most iconic truck engine to build two massive new V8s

Chevrolet is retiring the Silverado's 5.3-liter and 6.2-liter V8 engines for the 2027 model year, replacing them with a 5.7-liter and a 6.6-liter V8 family built on a refreshed GM Small Block design. The update signals a major powertrain shift for the Silverado lineup as GM bets on larger, more capable naturally aspirated V8s. The new engines will share architecture with GM's latest Small Block V8 platform, while Duramax continues to target fleet customers. Chevrolet argues that buyers still value a traditional, non-turbo V8 experience.

Within the competitive landscape, Ford still offers a 5.0-liter V8 in the F-150 but leans more on EcoBoost V6 or hybrid PowerBoost in other models. Toyota has moved away from V8s in the Tundra toward turbocharged hybrids with i-FORCE MAX, while Nissan keeps a natural V6 in the Frontier and shifts other models to turbo four-cylinders. Chevrolet's strategy appears to preserve the appeal of a classic V8 while embracing a new generation of power and design.
