How much does an IS300 weigh?
The Lexus IS300 sedan from the early 2000s typically weighs about 3,300 to 3,350 pounds when curb-weighted. Wagons and models with extra equipment can be heavier, and all-wheel-drive or automatic transmissions add mass.
Understanding what affects the IS300’s weight
The IS300 was produced from 2000 to 2005 as the first-generation model in the United States, powered by a 3.0-liter inline-6. Weight varies by body style and drivetrain. The numbers below reflect commonly cited curb weights for major variants and configurations.
Note: curb weight means the vehicle weight with a full fuel tank and standard equipment, but without passengers or cargo.
- IS300 sedan (2001–2005), rear-wheel drive: approximately 3,300–3,350 pounds (1,495–1,520 kg).
- IS300 SportCross wagon (2002–2005): roughly 3,400–3,700 pounds (1,540–1,680 kg).
- Automatic-equipped or all-wheel-drive variants: typically at the higher end of these ranges due to extra components.
These figures reflect broad market estimates. For a specific car, the exact curb weight can vary based on options, trim levels, and manufacturing revisions used in a given year.
How to verify the weight for a specific IS300
To confirm the exact curb weight for a particular IS300, use one or more of these sources:
- Door placard/sticker: The driver’s door jamb usually lists curb weight or GVWR for that specific vehicle.
- Owner's manual: Check the specifications section for the curb weight or GVWR.
- VIN or build sheet: Some dealers or Lexus tech portals can pull the exact weight from the VIN.
- Factory service manuals: These may include weight data for the relevant model year and drivetrain.
In practice, for a typical IS300 sedan, expect a curb weight near the lower end of the range if options are minimal, and toward the higher end if the car has features like a sunroof, alloy wheels, or other equipment.
Summary
The IS300’s curb weight varies by year, body style, and drivetrain. Sedans generally sit in the low 3,300s pounds, while the SportCross wagon is heavier, and options such as automatic transmissions or all-wheel drive push weight higher. For precision, check the vehicle’s door sticker or build sheet for the exact number.
