You can be forgiven for not being able to name the biggest Lexus SUV or calling out an incorrect answer when responding to that question. The 2025 Lexus LX hasn’t received much love from its maker as recently as the newer Lexus TX and recently refreshed Lexus GX hogged the limelight. Although somewhat hidden in the fog of publicity for the TX, GX, and the ever-popular and sales-leading Lexus RX, the LX does rule the size roost of Lexus SUVs. Oh, and by the way, Lexus gave the lavish LX a hybrid variant for 2025.
What Is the Biggest Lexus SUV?
The biggest Lexus SUV designation goes to the TX when considering seating capacity and max cargo room. It’s also the longest. However, some might argue that the Lexus LX is the biggest since it’s classified as full-size, while the GX, TX, and RX are midsize. Still, when faced with the widest and tallest, the GX will win. Here are the numbers.

Our Take
The differences between the LX and GX aren’t particularly transparent. The LX is more about luxury, while the GX leans more toward capability. Both are truck-based SUVs, which translates into rugged durability. On the other hand, the car-based TX targets families in need of a 3-row luxury conveyance. In the end, the LX is roundly considered to be the Lexus flagship. The bottom line then is: Depending on your specific needs, you can’t go wrong with any of these luxury SUVs.
