How fast is the GS400?
In typical conditions, the Lexus GS400 reaches 0–60 mph in about 5.8 seconds and is electronically limited to around 149 mph.
This article examines how fast the GS400 actually was when new, what contributed to its performance, and how those numbers translate to today’s driving conditions. The focus here is the US-market GS400, produced around 1998 to 2000 as the sportier variant of Lexus’ second‑generation GS lineup. It used a 4.0-liter V8 and a four-speed automatic, with performance figures that placed it in the mid‑range among contemporary luxury sedans.
What is the GS400?
The GS400 was Lexus’ V8-powered variant of the second‑generation GS sedan, built for model years around 1998–2000 in the United States. It employed a 4.0-liter V8 (the 1UZ-FE) paired with a four‑speed automatic transmission and a curb weight near four thousand pounds, depending on options. It sat between the GS300 and the later GS430 in the lineup and was eventually replaced by the GS430 family in the early 2000s.
Performance figures
Here are the core speed metrics typical of stock, US‑spec GS400s from the late 1990s to early 2000s.
- 0–60 mph: Approximately 5.6–5.9 seconds in standard condition
- 1/4 mile: Roughly 14.2–14.8 seconds at around 92–100 mph
- Top speed: Electronically limited to about 149 mph
These figures reflect controlled tests and common user experience, with warmth, tire choice, and maintenance affecting real-world results.
Engine, drivetrain and dimensions
Core specifications
The GS400 used Lexus’ 1UZ-FE 4.0-liter V8, mated to a four-speed automatic transmission. The car’s curb weight typically landed near 3,800–4,000 pounds, depending on options. The powertrain was tuned to deliver refined, confident acceleration and a smooth, comfortable ride rather than outright track‑sport performance.
Performance context
Compared with many contemporaries in the luxury-sedan segment, the GS400 offered strong mid‑range torque and a premium, quiet driving experience. Its top speed was governed around 149 mph, which was a common ceiling for many full‑sized luxury sedans of that era.
Factors that influence speed today
Even with official figures from the late 1990s, real-world results today vary widely. Several factors influence how fast a GS400 feels or performs on the street or at a track.
- Tire condition, grip and suitability for the car’s mass
- Engine health, maintenance history (oil, spark plugs, ignition timing)
- Vehicle weight from passengers, cargo, and aftermarket upgrades
- Weather, altitude, and air quality
- Transmission health and fluid condition
With proper maintenance and fresh tires, a well-kept GS400 can approach the original performance figures more consistently; aging components typically slow times modestly.
Bottom line and context
The GS400 represented Lexus’ effort to blend luxury and performance in a refined V8 package. In stock form, expect roughly mid‑five‑second 0–60 mph times in favorable conditions and a governed top speed near 149 mph. Real-world results depend on maintenance, tires, and driving conditions, as with most vintage luxury performance cars.
Summary
In its heyday, the GS400 delivered solid acceleration and high-speed capability for a luxury sedan, with 0–60 mph times in the upper‑5 seconds and a top speed around 149 mph. Today, the most faithful reproduction of its speed depends on meticulous upkeep, proper tires, and an engine that’s been well maintained. It remains a respectable classic for drivers who value a smooth, refined V8 experience alongside comfortable everyday usability.
What is the 0-60 time for a 2000 Lexus GS400?
5.7 seconds
The 2000 GS ranges in power from the GS 300 Sedan 4D with 220 horsepower and a 0-60 time of 7.8 seconds to the GS 400 Sedan 4D with 300 horsepower and a 0-60 time of 5.7 seconds.
Is the Lexus GS 450H a fast car?
With a 3.5-liter 338-horsepower V6 engine, the GS450h has ample power and quick, hesitation-free acceleration.
How fast is a Lexus GS400?
The GS400 had 300 horsepower and 310 ft-lbs of torque, and sprinted from 0-60 mph (or 0-96 km/h) in 5.7 seconds. Real world tests have actually bested Lexus' estimate, clocking its fastest real-word acceleration figure in 5.4 seconds.
How fast can a Lexus GX 460 go?
The top speed of a Lexus GX 460 is estimated to be around 110-111 mph, though this is often electronically limited. While the vehicle is capable of reaching these speeds, it is not a comfortable or stable vehicle at such high velocities, and owners report it feels unstable at speeds over 90 mph.
- Electronically limited speed: The top speed is electronically limited to approximately 110-111 mph.
- Driving stability: Drivers have reported that the vehicle feels unstable and "floaty" at high speeds, particularly over 90 mph.
- Driving experience: Reaching speeds over 100 mph is not a pleasant experience for most drivers.
