How much does the IS300 weigh?

The curb weight of the Lexus IS300 is roughly 3,400 pounds (about 1,540 kilograms), with exact numbers varying by year, transmission, and installed options.


What determines the IS300’s weight


Weight in this model line is shaped primarily by the 2JZ-GE 3.0-liter engine, the chosen transmission, and the level of standard equipment. The IS300 produced for the US market from 2001 through 2005 was largely rear-wheel drive, with different transmission choices affecting overall mass. Optional features and regional specifications can lead to small variations in curb weight from one vehicle to another.


Estimated curb weights by configuration


Here are typical curb weight ranges for the first-generation IS300 in the US market, reflecting common transmission choices and standard equipment. Exact figures can vary by model year and market.



  • IS300, rear-wheel drive, manual transmission: roughly 3,350–3,420 lb (1,520–1,550 kg).

  • IS300, rear-wheel drive, automatic transmission: roughly 3,380–3,480 lb (1,534–1,579 kg).


These ranges capture the common weights seen across model years; some factory listings and owner data show slight deviations based on options, paint, and minor spec changes.


Notes for buyers and enthusiasts


Why weight matters for performance


Weight influences acceleration, handling, braking, and fuel economy. The IS300’s weight, balanced with its engine and chassis, contributes to its characteristic sporty feel for a car of its era. When comparing to newer or different Lexus models, the curb weight can be a useful context for performance differences.


Put simply: the practical takeaway


For the first-generation IS300 (2001–2005, US market), expect a curb weight in the low-to-mid 3,400-pound range, with small differences based on transmission and equipment.


Summary


The IS300’s weight centers around approximately 3,400 pounds, though precise curb weight varies by year, transmission choice, and installed options. This reflects its early-2000s design and the 2JZ-GE powertrain that defined the model.
