What are the interior dimensions of the Lexus RX 300?
The interior dimensions of the Lexus RX 300 vary by model year and market. There isn’t a single universal set of cabin measurements for every RX 300, because the badge has been used on multiple generations and trims. To give you precise numbers, I’d need the specific year and region you’re looking at. In the meantime, this article explains what counts as interior space and how to obtain exact figures.
What counts as interior dimensions
Interior dimensions cover front and rear headroom, legroom, shoulder room, and hip room, plus cargo capacity behind the second row and with the rear seats folded. These figures depend on seat positions and whether the rear seats are upright or folded, and they can differ between generations and trims.
Generation overview and naming notes
In some markets the RX 300 badge referred to the early RX models that used the XU30/XU20 platform (roughly mid-2000s), while other markets used RX 330 and later RX 350 designations. These naming shifts coincided with different interior packaging, so cabin measurements changed over time. Always verify the exact figures for your year and market.
How to get exact numbers for your RX 300
Provide the model year and market to receive precise cabin dimensions, including front/rear headroom, legroom, shoulder room, hip room, and cargo capacity.
To locate the exact interior dimensions, consult the following sources and steps:
- Determine the model year and market (US, Europe, Asia, etc.).
- Look up the official Lexus specification sheets or the owner's manual for that year.
- Check reputable automotive databases and brochures for cabin measurements (headroom, legroom, shoulder/hip space) and cargo figures.
Note: The numbers you obtain will reflect a specific seating configuration (e.g., seats upright, sunroof or no sunroof, and any trim changes). Compare the measurements in the same configuration to get an accurate sense of space.
Summary
The Lexus RX 300 does not have a single, universal interior measurement set. Interior dimensions depend on the generation, year, and regional market. If you share the exact model year and market you’re interested in, I can provide the precise figures for front and rear headroom, legroom, shoulder and hip room, plus cargo space with both the second row up and folded.
