How much horsepower does the GS300 have?
The Lexus GS300 typically delivers about 225 horsepower, though the exact figure depends on the model year and market. This article rounds up the main specifications by generation and notes regional variations.
Generations and horsepower
The following figures reflect the most common factory outputs for the GS300 across its major generations, with notes on regional differences where relevant.
- 1993–1997: Lexus GS300 (first generation, S140) — 3.0-liter inline-six (2JZ-GE) producing about 225 hp (167 kW) at around 5,800 rpm; torque near 210 lb-ft (285 Nm).
- 1998–2005: Lexus GS300 (second generation, S160) — US-market typically rated at 225 hp; many other markets recorded similar outputs, with some variant tuning pushing roughly 235–240 hp in certain regions.
- Notes on later GS300 designation — In some markets, the GS line carried a 3.0-liter engine into the late 2000s, but the US market largely shifted to the GS350 (3.5L) and other trims; non-US GS300 variants generally fall in the ≈230–240 hp range depending on local specifications and emissions rules.
Conclusion: Across its run, the GS300 usually sits in the mid-200s horsepower range, with US-spec models commonly around 225 hp and regional variations nudging numbers higher or lower by a few horsepower.
Market-specific considerations
Exact horsepower figures can vary by country, model year, and equipment. For a precise number, consult the original window sticker or the vehicle’s VIN-based build sheet for a specific car.
Context and clarifying notes
The GS300 nameplate is primarily tied to older Lexus generations. In the United States, newer models moved to the GS350 and beyond, so “GS300” branding is most relevant to earlier years and certain international markets. Performance in real-world driving also depends on factors such as weight, gearing, and drivetrain tuning, not horsepower alone.
Summary
In practical terms, the GS300 typically offers about 225 horsepower, with minor regional variations that can push numbers toward roughly 235–240 hp in some markets. For a specific car, verify the exact specification from official documentation.
Does the GS300 have a 2JZ?
Yes, the Lexus GS300 comes with a naturally aspirated 2JZ-GE engine from the factory, but the high-performance turbocharged 2JZ-GTE was never installed in the GS300 from the factory and is only available via engine swaps. The 2JZ-GTE engine was exclusive to the Japanese market Toyota Aristo and the Supra.
Factory engine
- 2JZ-GE: The GS300 was originally equipped with the 3.0L 2JZ-GE, a naturally aspirated inline-six engine.
- VVTi: Many models from 1995 and later feature a VVTi version of the 2JZ-GE.
Turbocharged engine (engine swap)
- 2JZ-GTE: To get the turbocharged 2JZ-GTE, you would need to perform an engine swap, often using a motor from a JDM Toyota Aristo.
