What engine does a GS 350 have?
The GS 350 is powered by a 3.5-liter V6 engine. Across its generations, Lexus has used two variants of the 3.5-liter V6 from the Toyota 2GR family, with later models adopting direct injection for improved efficiency and response.
Engine family and key variants
Below is a concise guide to the core engine options that have powered the GS 350 across model years.
- Engine capacity and layout: 3.5-liter V6 in a traditional V-shaped configuration with DOHC setup and variable valve timing.
- Two main variants: the older 2GR-FE and the later direct-injected 2GR-FKS. The 2GR-FE appears on earlier GS 350 models, while 2GR-FKS appears on later editions with improved efficiency and output.
- Performance notes: horsepower and torque vary by year and market, generally ranging from the upper 200s to around 311 horsepower, with corresponding torque in the mid to high 200s lb-ft.
These differences reflect Lexus' ongoing updates to meet stricter emission standards and performance expectations while maintaining smooth, refined operation.
Engine evolution by model year
The GS 350's heart has evolved from older 2GR-FE versions to newer direct-injected 2GR-FKS iterations, aligning with broader Toyota/Lexus engine updates in the 2010s.
- Early GS 350 models (roughly 2006–2011): propelled by the 3.5L 2GR-FE V6, with performance tuned for luxury-sedan refinement.
- Mid-cycle updates (circa 2013–2015): introduced or transitioned to the 2GR-FKS direct-injected variant to improve efficiency and response.
- Recent GS 350 versions (post-2016): generally continue with the 2GR-FKS configuration, emphasizing smoother power delivery and improved fuel economy.
If you need the exact engine code for a specific car, check the vehicle identification label under the hood or the owner's manual for the precise specification by year and market.
Summary
In short, the GS 350 is powered by a 3.5-liter V6 from Toyota's 2GR engine family. The engine has evolved from the older 2GR-FE to the direct-injected 2GR-FKS in later models, with horsepower and tuning varying by year and market. This configuration underpins the GS 350’s balanced blend of performance and luxury.
