What is the 0-60 on a 2009 Lexus GS 450h?
The 0-60 mph time for the 2009 Lexus GS 450h is typically in the mid-5-second range, about 5.5 to 5.9 seconds under normal testing. Times can vary with conditions and equipment.
The GS 450h pairs a 3.5-liter V6 with electric motors in Lexus' Hybrid Synergy Drive to deliver roughly 340 horsepower. Acceleration depends on battery state of charge, drive mode, tire grip, temperature, and vehicle load. As a result, real-world results often hover in the mid-5-second range, but can slip toward six seconds under less favorable conditions.
Benchmarks and typical results
What follows is a snapshot of commonly cited ranges from automotive testing. Individual results vary based on conditions and testing methodology.
- Typical 0-60 range: approximately 5.5–5.9 seconds in standard testing conditions.
- Best-case tests (ideal track conditions, good tires, optimal battery state): around 5.2–5.5 seconds.
- Less favorable conditions (hot or cold weather, worn tires, or additional load): may approach or exceed 6.0 seconds.
In practice, most testers and owners report acceleration in the mid-5-second range, with variations explained by drivetrain management and environmental factors.
Factors that influence acceleration
Several variables influence the measured 0-60 performance of the GS 450h. Buyers and testers should consider these when evaluating times.
- Battery state of charge and temperature, which affect electric motor output.
- Tire condition and grip, including tire composition and road surface.
- Ambient temperature, altitude, and humidity, which affect engine and motor efficiency.
- Vehicle weight, including passengers and cargo.
- Drive mode selection (EV, Normal, Power) and how the hybrid system blends gasoline and electric power.
Because the hybrid system blends torque from electric motors with gasoline power, times can swing a few tenths of a second depending on start conditions and mode.
Model-year context
Similar drivetrain across 2007–2010 GS 450h
The 2009 GS 450h uses the same Hybrid Synergy Drive setup as other early GS 450h models, with a 3.5-liter V6 paired to electric motors. For that generation, acceleration figures are broadly similar across model years; minor updates did not substantially change straight-line performance.
Summary
Bottom line: In real-world driving, the 2009 Lexus GS 450h typically posts 0-60 mph times in the mid-5-second range (about 5.5–5.9 seconds). Times vary with battery state, temperature, tires, load, and drive mode. If you’re evaluating one, plan to test under your usual conditions to gauge performance.
