Is 350 Lexus V6 or V-8?
The short answer: in most Lexus models that carry the 350 badge, the engine is a 3.5-liter V6 rather than a V8. However, the badge alone isn’t a reliable predictor in every generation or model, since recent lineups have introduced turbocharged four-cylinders and hybrids that wear the 350 badge for branding rather than displacement.
How the 350 badge has evolved
Lexus has used numeric designations to hint at engine size or performance, but the interpretation has shifted over time. Traditionally, 350 signified a 3.5-liter V6 in popular models such as RX, IS, and ES lines. In later years, some models with the 350 badge moved to other powertrains, including turbocharged four-cylinders or hybrids, depending on market and generation.
Commonly 350-badged Lexus models and their engines
Below is a quick look at models that have carried the 350 badge and the engines they typically use. Note that engine options can vary by year and market, so always verify for a given vehicle.
- RX 350 — 3.5L V6
- IS 350 — 3.5L V6
- ES 350 — 3.5L V6
- GS 350 — 3.5L V6 (older generation)
These models have traditionally relied on Lexus's 3.5-liter V6 for balanced performance and smooth operation.
Exceptions and modern changes to the badge
In newer Lexus lineups, the 350 badge does not always mean a V6 engine. Some models use different powertrains while retaining the designation, and others use a different number altogether. The NX lineup, for example, shifted to a smaller turbocharged four-cylinder for its 350-badged variant, and the NX 350h hybrid uses a 2.5L hybrid setup.
- NX 350 — 2.4L turbocharged inline-4
- NX 350h — 2.5L hybrid inline-4
When shopping, it’s essential to check the specific model year and trim to confirm the engine, since the badge alone isn’t a reliable predictor across all generations.
How to verify the engine in your target vehicle
Look up the vehicle’s VIN, review the window sticker or build sheet, and check the engine code (for example, 2GR-FKS or 2UR-FSE indicates a V6, while a 2.4L turbo is typically indicated by the turbocharged inline-4 designation). The owner's manual and official Lexus documentation are also reliable sources.
Summary
Across the Lexus lineup, the 350 badge has historically signified a 3.5-liter V6 in sedans and many SUVs. However, newer models and certain markets have used the 350 badge with different engines (notably turbocharged four-cylinders or hybrids). Always verify the exact engine by checking the VIN, window sticker, or official documentation rather than relying solely on the badge.
