How much bigger is the Lexus TX than the RX?
The Lexus TX is roughly 9 to 11 inches longer than the RX, mainly due to its added third-row design and extra overhang, with a wheelbase about 2 to 3 inches longer. This size difference translates into noticeably more interior room and cargo versatility on the TX.
Size in numbers: length, wheelbase and space
To give readers a clear picture, here are the key exterior dimensions and how they compare. Official figures come from Lexus and are listed for typical configurations; trims and options can slightly affect exact numbers.
- Overall length: TX is about 203 inches long, while RX sits in the low 190s (roughly 192–194 inches). Difference: roughly 9–11 inches.
- Wheelbase: TX runs around 112 inches, versus RX at about 109 inches. Difference: about 2–3 inches longer for the TX.
- Interior and cargo space: The TX’s added length supports a genuine third row and greater cargo capacity behind the third row, whereas the RX remains a more compact two-row SUV with less third-row practicality.
In practical terms, the extra length of the TX mainly translates into the ability to seat a full third row and carry more luggage or gear, especially when the third row is folded. The RX, by contrast, prioritizes maneuverability and efficiency in a smaller footprint.
What this means for buyers
For families or buyers who frequently rely on a third row or need more cargo space, the TX offers tangible advantages in size and practicality. If ease of parking, tighter city driving, and overall agility matter more, the RX remains the more compact and nimble choice.
Other considerations
Beyond exterior dimensions, shoppers should compare interior layout, seating comfort, technology packages, fuel economy, and price. The TX’s larger footprint can influence garage space and daily usability, while the RX might edge out in efficiency and parking considerations.
Summary
The Lexus TX is approximately 9–11 inches longer than the RX, with a wheelbase about 2–3 inches longer. This yields a larger interior with a true third row and more cargo-carrying capability, making the TX the roomier option for families or those who value passenger versatility. The RX remains the smaller, more maneuverable luxury SUV for commuters and urban driving.
