How fast is the Lexus GX 550?

There is no Lexus GX 550 in Lexus's current lineup. The speed figures most commonly associated with the GX family come from the GX 460, which typically achieves 0–60 mph in about 7.5–7.8 seconds and tops out around 124–125 mph.


The question implies a model name that Lexus has not released. In this article, we’ll explain the current GX lineup and what speed numbers you can expect from it, and why a hypothetical GX 550 does not have official data.


Current GX performance figures


Below are the key speed-related specifications for the production GX lineup in recent years. Figures vary by year, drivetrain, and optional equipment.



  • 0–60 mph: approximately 7.5–7.8 seconds for the GX 460 (the typical current GX model in most markets).

  • Top speed: electronically limited to about 124–125 mph in most model years.

  • Real-world factors: added weight from off-road equipment, towing packages, or four-wheel drive can alter acceleration slightly; tires and traction conditions can also affect perceived speed.


Despite the lack of a GX 550, the GX lineup remains oriented toward capability and comfort rather than extreme straight-line speed.


Is there a GX 550 planned?


As of 2025, Lexus has not announced or released a GX 550 variant. Any talk of a higher-horsepower GX remains speculative until official information emerges from Lexus.


Summary


The Lexus GX line does not include a GX 550. The closest production model, the GX 460, typically posts 0–60 mph times in the mid-to-high 7 seconds and a top speed around 124–125 mph. Real-world performance varies with year, drivetrain, and equipment, but speed has never been the GX’s primary focus compared with off-road capability and luxury comfort. If speed is the priority, potential future announcements or different models would be the route to explore.
