Is the IS350 heavy?
The IS350 is not considered unusually heavy for its class. Across generations, its curb weight sits in the mid-weight range for a luxury sport sedan, generally between roughly 3,400 and 3,900 pounds depending on year, drivetrain, and trim.
Weight by generation
Weight varies by generation and configuration. The following ranges reflect typical curb weights for common IS350 configurations, with all-wheel drive (AWD) usually adding mass compared to rear-wheel drive (RWD).
- First generation (2006–2013): RWD IS350 typically sits in the mid-3,400s pounds; AWD variants tend to be closer to the upper 3,700s to around 3,800 pounds, especially when loaded with options.
- Second generation (2014–2020): RWD IS350 generally around 3,500–3,600 pounds; AWD models commonly about 3,700–3,900 pounds, depending on trim and equipment.
- Current/latest generation (2021–present): RWD IS350 commonly in the 3,600–3,700+ pounds range; AWD variants typically around 3,800–3,900+ pounds, influenced by technology packages and safety gear.
These numbers illustrate how weight has hovered in a stable band but shifted slightly upward with newer safety equipment, infotainment features, and all-wheel drive availability. In the broader market, the IS350 sits alongside peers from BMW, Audi, and Mercedes in a similar weight class, with variations driven by drivetrain and trim choices.
How weight affects driving dynamics
Weight influences handling, braking, and ride quality. The IS350’s V6 provides strong, smooth power to justify its heft, while chassis tuning aims to keep the car responsive and balanced. AWD adds traction and stability at the cost of some extra mass, which can subtly affect turn-in feel and fuel economy. Lighter, sport-focused trims (when available) may feel more agile, whereas heavier configurations tend to offer more grip and versatility in varied conditions.
Drivetrain and trim differences
Drivetrain choice is the main driver of weight differences. RWD models are typically lighter and can feel more nimble, while AWD variants bring improved grip and predictability in rain or snow but carry additional mass. Performance-oriented trims like F Sport variants often add weight due to upgraded brakes, a reinforced chassis, and adaptive suspension hardware, which shifts the weight balance but can enhance overall handling and braking performance.
Bottom line
In sum, the IS350 is not an outlier for heaviness in its segment. It remains a mid-weight luxury sport sedan, with typical curb weights that reflect a balance between robust V6 power, safety tech, and drivetrain options. Prospective buyers who prioritize lightness and razor-edged agility should weigh the benefits of RWD configurations or lighter trims, while those who value all-weather capability and extra equipment may accept the extra mass.
Summary
The IS350’s weight ranges from roughly the mid-3,400s to the upper-3,900s pounds across its generations, with drivetrain and trim choices driving the differences. It’s not considered especially heavy for its class, but buyers should still consider how weight affects handling, braking, and efficiency when choosing between RWD, AWD, and various trim levels.
