Lexus GX vs. Lexus LX: Which Model is Bigger?

Most shoppers assume the LX is larger in every way because it sits at the top of the Lexus SUV lineup. The numbers tell a more interesting story. This guide from Lexus of Mobile compares the 2026 GX and LX on size, cargo, towing, and seating, so you can choose the one that fits your garage, your passengers, and your weekends.

GX vs. LX Size, Cargo, and Towing at a Glance

Exterior size: closer than you think

The LX is about 3.5 inches longer than the GX, mostly in its overhangs, since both ride on the same 112.2-inch wheelbase. Width is nearly identical. The GX is the taller of the two, especially in Overtrail form. For most drivers, the LX does not feel dramatically larger on the road. The bigger differences show up in cargo, power, and price.

Cargo space: the GX wins at maximum capacity

With all seats in use, the two are close, at about 10 to 11 cubic feet behind the third row. Fold the rear seats, and the GX opens up to 76.9 cubic feet, or 90.5 cubic feet in the two-row Overtrail, compared with 64 cubic feet in the LX 600. If you regularly haul coolers, sports gear, or luggage, the GX is the more practical cargo vehicle.

Power and refinement: the LX’s advantage

The LX offers more power, with 409 horsepower in the LX 600 and 457 horsepower in the LX 700h hybrid. It also delivers the flagship cabin materials, rear-seat comfort, and refinement Lexus reserves for the top of its SUV lineup. Learn more on our 2026 LX Hybrid research page.

How to Choose Between the GX and LX

Because the two SUVs are so close in footprint, the better question is not which is bigger, but which uses its size the way you need it.

Choose the LX if

• Flagship luxury, rear-seat comfort, and cabin refinement are your top priorities
• You want the most power, or a hybrid option with the LX 700h
• Your passengers matter more than your cargo

Choose the GX if

• You want more maximum cargo space and the highest tow rating
• Off-road capability matters, especially with the Overtrail grades
• You want a full-size, body-on-frame Lexus SUV at a lower starting price than the LX

Seating also varies by grade on both models, so confirm the configuration you need before you compare prices. The best way to decide is to sit in both third rows, fold the seats, and load your own gear on the same visit.

Garage Fit and Daily Driving Around Mobile

For many Mobile-area households, garage fit is the deciding factor, and it is where shoppers often check the wrong measurement.

• Garage depth: The LX needs about 3.5 more inches of length. In most garages built for full-size SUVs, either one fits.
• Garage door height: The GX Overtrail stands up to 77.2 inches tall, taller than the LX. If you have a low garage door or plan to add a roof rack, measure height first.
• Downtown parking: With identical wheelbases and nearly identical widths, the GX and LX feel similar in tight lots. Do not expect the GX to park like a midsize crossover.
• Weekend towing: If you tow a boat to the Eastern Shore or a camper along the Gulf Coast, the GX’s higher tow rating gives you more margin.

When the GX Is the Smarter Pick

For many buyers, the GX delivers more of what they actually use. It matches the LX’s wheelbase, beats it on maximum cargo and towing, and offers serious off-road capability in Overtrail form, all at a lower price point. If you are stepping up from an RX or TX and want true full-size SUV capability, the GX is usually the natural next move.

The LX earns its higher price through power, refinement, and the most luxurious cabin in the Lexus SUV family. If those are your priorities, the LX is worth the step up. You can compare both against the rest of the lineup in our Lexus model showroom.
