What is the curb weight of a 2018 Lexus IS 300 F Sport?
The curb weight of the 2018 Lexus IS 300 F Sport is about 3,700 pounds for the rear-drive model, with all-wheel-drive versions heavier by roughly 150–200 pounds. This reflects the influence of drivetrain and optional equipment on total mass.
In this article, we’ll outline the typical curb weight for the 2018 IS 300 F Sport, explain how weight varies by drivetrain and equipment, and discuss what those differences mean for handling, performance, and fuel economy. The figures below are representative of common configurations for this model year in the U.S. market.
Curb weight by drivetrain
Before delving into the numbers, note that the IS 300 F Sport is primarily offered in rear-wheel drive, with an all-wheel-drive option available. The F Sport package adds performance-oriented components that can affect overall mass. The following figures reflect typical curb weights reported for the 2018 model year in standard trim with the F Sport package.
- Rear-wheel-drive (RWD) IS 300 F Sport: approximately 3,600–3,700 pounds (about 1,630–1,680 kg).
- All-wheel-drive (AWD) IS 300 F Sport: approximately 3,800–3,900 pounds (about 1,720–1,770 kg).
In practice, exact curb weight can vary with optional equipment, wheel/tire sizes, and whether the vehicle carries a full-sized spare or a tire repair kit, among other factors.
Why the weight varies
The weight difference between RWD and AWD versions reflects the additional drivetrain components required for all-wheel traction, such as the driveshaft, center differential, and related hardware. The F Sport package also adds features like larger wheels, a sport-tuned suspension, and sometimes upgraded brakes and body components, all contributing to a higher curb weight.
Context and implications
Weight affects several aspects of vehicle performance. Heavier cars generally experience slightly slower acceleration, subtle handling changes, and variations in fuel economy. For the IS 300 F Sport, the extra mass from AWD and optional equipment can influence these factors, though the car remains tuned for sporty handling in line with Lexus’ F Sport philosophy.
For buyers, the weight difference between RWD and AWD should be weighed against the intended use: RWD tends to offer lighter, more immediate response in dry conditions with a purer driving feel, while AWD provides enhanced traction in rain or light snow at the cost of added mass.
Additional notes and sources
Specific curb weight figures can vary by market, trim details, and production run. If you need an exact number for a particular VIN or dealer configuration, consult Lexus official specifications or a certified automotive weight database.
Summary: The 2018 Lexus IS 300 F Sport typically weighs around 3,600–3,700 pounds in RWD form and about 3,800–3,900 pounds when equipped with AWD. Real-world weight depends on options, wheels, and tires.
Summary of the article: Drivetrain and equipment choices drive the curb weight for the 2018 IS 300 F Sport, with RWD being lighter and AWD adding mass. Always verify the exact weight for a specific vehicle configuration if precision is needed for payload calculations or performance expectations.
