The 2004 is300 weight represents a specific data point for one of Lexus's most iconic luxury sedans, the third-generation IS 300. Understanding the exact curb weight, gross vehicle weight rating, and how this figure impacts the driving dynamics is essential for enthusiasts and potential buyers alike. This model year solidified the IS 300's reputation as a precise-handling performance luxury sedan, and its mass plays a critical role in that experience.
2004 Lexus IS 300 Curb Weight Specifications
For the 2004 model year, the Lexus IS 300 typically had a curb weight ranging from approximately 3,400 to 3,550 pounds. This range accounts for the different trim levels and optional equipment packages available. The base model is lighter, while versions equipped with the premium JBL audio system, larger wheels, or additional sound insulation will sit at the higher end of this spectrum. Knowing the specific weight of a particular vehicle is vital for understanding its performance capabilities.
Drivetrain and Configuration Impact
It is important to note that the 2004 IS 300 was exclusively powered by a rear-wheel-drive system. This layout, paired with a near 50/50 weight distribution, is a primary reason for its engaging and stable handling characteristics. The weight of the engine, positioned longitudinally in the front, contributes significantly to the front-to-weight balance. This precise engineering ensures the car feels planted at high speeds yet remains agile through tight corners, a balance that is directly influenced by its overall mass.
Performance Implications of the Weight
The 2004 is300 weight is a key factor in its dynamic behavior. A lighter vehicle can accelerate and brake more efficiently, but the IS 300's design prioritized a stable and composed ride over extreme lightness. The heftier curb weight contributes to a sense of quality and solidity on the highway, reducing wind and road noise intrusion. This results in a smooth, serene cabin environment that is characteristic of Lexus's luxury philosophy, even when the driver is seeking a more spirited drive.
Fuel Economy Considerations
Heavier vehicles generally require more energy to move, which translates to lower fuel efficiency. The 2004 IS 300's weight is a contributing factor to its EPA-estimated fuel economy, which typically ranged from 21 mpg in the city to 28 mpg on the highway for the automatic transmission. While not class-leading, these figures were reasonable for a midsize luxury sedan with its performance-oriented suspension and standard all-weather all-season tires.
