Is Lexus GS V6 or V8?
The standard Lexus GS uses a V6 engine (the GS 350), while the high-performance GS F uses a V8 (5.0-liter). The GS lineup was discontinued after the 2020 model year, so there are no new GS models available today.
Engine options in the GS lineup
Here are the core powertrains historically offered in the Lexus GS through its production years.
- GS 350 — 3.5-liter V6 (2GR-FSE/2GR-FKS) delivering around 311 horsepower and about 277–280 lb-ft of torque; paired with an 8-speed automatic transmission; rear-wheel drive is standard with all-wheel drive available in some years/markets.
- GS F — 5.0-liter V8 (1UR-GSE/2UR-GSE family) producing about 467 horsepower and 389 lb-ft of torque; paired with an 8-speed automatic; rear-wheel drive is standard (no factory AWD option).
Notes: Earlier generations of the GS offered hybrid variants in certain markets, but the main U.S.-market lineup centered on the V6-powered GS 350 and the V8-powered GS F. The GS F served as the performance halo car for the lineup.
Lifecycle status and what happened to the GS
In 2020 Lexus ended production of the GS in most markets, effectively ending the model's run. Since then, the brand has grown its other sedans and sportier offerings (such as IS, ES, LS, and LC) to cover the practical and performance-oriented segments that the GS once served. For buyers seeking similar power today, those models are the closest direct alternatives within Lexus’ current lineup.
What to know if you’re shopping used
For used-GS buyers, the primary choices are the V6 GS 350 and the V8 GS F. When shopping, consider maintenance history, mileage, and the availability of parts, since the model has been out of production for several years. Availability varies by region and model year.
Summary: The Lexus GS offered a V6 option in the GS 350 and a V8 option in the GS F; the lineup was discontinued after 2020, so there are no new GS models today. Buyers looking for current Lexus performance or luxury sedans should explore the IS, ES, LS, or LC as appropriate alternatives.
