What size engine is the Impala V6?
The Impala has used several V6 displacements over its history, with 3.8 liters (the 3800 Series II) and 3.6 liters being the most common. Earlier years saw smaller 3.4/3.5-liter V6 options, while the high-performance Impala SS relied on a V8 rather than a V6. The exact size depends on the model year and trim.
V6 sizes by generation
A concise look at the V6 displacements that appeared in Impalas over the years. This is a general guide; exact engine size can vary by year, market, and trim.
- 3.8-liter V6 (3800 Series II) — a staple in many late-1990s to early-2000s Impalas, known for durability and broad GM familiarity.
- 3.6-liter V6 — introduced in later generations as a primary V6 option, delivering modern efficiency and power in the 2010s era.
- 3.4-liter/3.5-liter V6 — smaller-displacement V6 options that appeared in some earlier years and models.
Note: The Impala SS and other high-performance variants used a V8 engine, not a V6.
Other powertrains offered
Beyond the V6, the Impala lineup also included four-cylinder engines (in some later generations) and V8 options for performance-focused trims. The exact combination depended on the model year and market.
- 2.5-liter four-cylinder — used in later-generation Impalas as a more economical option.
- V8 option (not a V6) — notably in the Impala SS, which emphasized performance over fuel economy.
When shopping for an Impala, verify the engine displacement for the specific year and trim via the VIN or official documentation to confirm the exact V6 size.
Production context and current status
Chevrolet ended production of the Impala for the North American market after the 2020 model year, making the V6 variants part of the car’s broader historical lineup rather than a current configuration.
Summary
Across its history, the Impala’s V6 engine sizes have typically included 3.8 L and 3.6 L as the main configurations, with smaller 3.4/3.5 L options appearing early on. The SS used a V8 instead of a V6. For precise information on a specific year and trim, check the VIN or official specifications.
