What Lexus GS has the most horsepower?
The Lexus GS F has the most horsepower in the GS lineup, delivering 467 horsepower from a 5.0-liter V8.
Beneath the numbers, the GS family spans several generations and powertrains, including regular gas models, a hybrid, and a high-performance flagship. This article breaks down which variant tops the horsepower chart and how the lineup compares across years and regions.
Power profile of the GS variants
Below is a concise comparison of horsepower across the main GS models, noting that figures vary by year and market.
- GS 300: approximately 245 horsepower from a 3.0-liter inline-six, depending on year and market.
- GS 350: about 311 horsepower from a 3.5-liter V6, with minor year-to-year variation.
- GS 450h: combined output of about 338 horsepower from the hybrid powertrain (gas engine plus electric motors).
- GS F: 467 horsepower from a 5.0-liter V8, the peak variant in the lineup.
Engine and drivetrain configurations influence torque and acceleration as well, but horsepower offers a straightforward basis for comparing peak output across the GS range.
Detail on the GS F's performance
The GS F, introduced in 2013 as the performance flagship, uses a naturally aspirated 5.0-liter V8 paired with an eight-speed automatic, delivering strong but high-revving power and a focus on track-capable performance alongside daily usability.
Notes on model year and market variations
Specifications can vary by year, market (North America, Europe, Japan), and updates. The GS F's horsepower remained around 467 hp across its production span, while non-F models show broader variation in horsepower due to engine updates and regulation changes.
Summary
In short, the top horsepower among Lexus GS variants is found in the GS F, at 467 hp. The other variants—GS 300, GS 350, and GS 450h—offer progressively lower power figures, underscoring the GS F's role as the performance benchmark. The GS line was discontinued after 2020, but its horsepower hierarchy remains a reference point for enthusiasts and reviewers.
