How much does a Lexus IS350 curb weight?
The curb weight of a Lexus IS350 typically falls in the range of about 3,500 to 3,900 pounds (roughly 1,588 to 1,769 kilograms), with the exact figure depending on the model year, drivetrain, and trim.
Curb weight is the vehicle’s weight with standard equipment and fluids, not including passengers or cargo. For the IS350, factors such as whether the car is rear-wheel drive or all-wheel drive, the trim level (base, Premium, or F Sport), and optional equipment all influence the precise weight. This article lays out how much IS350s generally weigh and why weights vary across configurations.
What affects curb weight
The mass of a Lexus IS350 depends on the generation and year, the drivetrain configuration, and the presence of options or performance packages. Heavier components—like an all-wheel-drive system, larger brake packages, or sport-focused hardware—tend to push the curb weight upward. Over different generations, changes in materials and drivetrain layouts also shift the overall mass.
Drivetrain and trim effects
Rear-wheel-drive IS350s are usually lighter than their all-wheel-drive counterparts. Performance-oriented trims such as F Sport add equipment that can increase curb weight relative to the base model, though variations in wheels or tires can slightly offset this in some cases. Transmission choice and the inclusion of items like a spare tire can also cause small weight differences.
Typical curb weight ranges by configuration
Below are common weight ranges for typical IS350 configurations. Exact figures vary by year, options, and market (some regions offered slightly different specs).
- IS350 RWD (base or Premium trims): about 3,500–3,650 lb (1,588–1,658 kg)
- IS350 AWD: about 3,800–3,900 lb (1,724–1,768 kg)
- IS350 F Sport (RWD): about 3,700–3,900 lb (1,676–1,768 kg)
For precise curb weight, consult the specific model year’s brochure or the vehicle’s certification label, as weights can vary based on options like larger wheels, audio systems, and safety packages.
Why this matters
Curb weight affects handling, acceleration, braking, and fuel economy. Heavier variants may feel less nimble but offer greater stability at speed, while lighter configurations can enhance agility. Knowing the curb weight helps with understanding performance expectations and payload considerations.
Summary
The Lexus IS350 typically weighs between roughly 3,500 and 3,900 pounds, with exact numbers depending on year, drivetrain (RWD vs AWD), and trim level. For a precise figure, check the vehicle’s door jamb sticker or official Lexus documentation for the specific model.
