How much horsepower does a 2004 GS 400 have?
The 2004 Lexus GS lineup did not include a GS 400 in the United States; the available trims were the GS 300 and the GS 430, with the GS 430 rated at about 290 horsepower. The GS 400 badge was used on earlier generations (circa 1998–2000) and those cars typically carried roughly 290–300 horsepower depending on the market.
This distinction matters for buyers and researchers who encounter the GS 400 name, especially when comparing models across years or regions. Below is a concise look at how the horsepower figures stack up across generations so you can interpret a vehicle’s power more accurately.
Context: how the GS line evolved
Lexus grouped its high-performance GS models by engine size, with the 400 and 430 designations signaling different V8 configurations across generations. The U.S. market saw two main high-horsepower variants during this era, but the 400 badge itself did not appear in 2004 as a separate model. The figures cited here reflect typical factory ratings from official materials and widely cited references.
GS 400 (late 1990s): powerplant and output
Applications of the 4.0-liter V8 (1UZ-FE) in the late-1990s GS 400 produced roughly 290–300 horsepower, with torque commonly reported in the 300–320 lb-ft range. Variations existed by market and year due to emissions and tuning.
GS 430 (early 2000s, including 2004-era US lineup)
The 4.3-liter V8 used in the GS 430 delivered about 290 horsepower, with torque around 320 lb-ft. This was the top-end GS option in the 2004 US lineup, offering the closest performance badge to what some buyers sought under the “GS 400” banner elsewhere.
Bottom line for the 2004 model year
For a 2004 vehicle, you would encounter the GS 430 at roughly 290 horsepower, not a GS 400. If you come across a vehicle labeled GS 400 from that era in another market, expect horsepower figures in the neighborhood of 290–300 hp, depending on regional specifications and production year.
Summary
There is no 2004 GS 400 in the U.S. lineup. The 2004 GS models are the GS 300 and GS 430, with the latter delivering about 290 horsepower. The GS 400 badge belongs to earlier generations, where power ratings hovered around 290–300 hp. Always verify the specific vehicle’s build sheet or VIN-derived specifications for exact horsepower in your region.
