General Motors has confirmed that the next-generation Chevrolet Silverado and GMC Sierra full-size trucks will be unveiled this year. This update is significant because the current models have been on the market since 2019, with only minor updates in 2022.
Upcoming Engine Advancements
The biggest change coming with these trucks will be a new sixth-generation V8 engine. GM has already invested $888 million into its development, with production starting in 2027. The current V8 options in the Silverado and Sierra range from 355 horsepower to 420 horsepower, with even more powerful supercharged versions available in other GM vehicles like the Cadillac Escalade-V (682 hp).
GM promises that the new engine will deliver more power while improving fuel efficiency. They plan to achieve this through innovations in combustion and thermal management, addressing concerns about both performance and emissions.
Production & Timing
The exact release date for the new Silverado and Sierra remains unclear, but the announcement came during GM’s fourth-quarter earnings report for 2025, suggesting a reveal sometime this year. The 2022 mid-cycle refresh added popular trims like the ZR2 and AT4X, but the new models will represent a more substantial overhaul.
Past Challenges & Future Outlook
Production of the current generation trucks faced disruptions in 2021 due to the global chip shortage, forcing GM to temporarily ship some vehicles without features like heated seats. The new generation is expected to avoid such issues with improved supply chain management.
The next-generation Silverado and Sierra are critical models for GM, so changes will likely be evolutionary rather than revolutionary. Expect a refined design, enhanced performance from the new V8, and a continued focus on capability and technology.
