Riding on an all-new platform with an updated powertrain and a load of more modern features, the new GX550’s rugged appearance is about the only thing that ties it to its outdated forbear. The new model’s boxy, Land Cruiser-inspired exterior looks like it will age well—a good thing since the GX has a history of lengthy product cycles. The 2024 GX550 rides on the same body-on-frame platform as the Toyota Sequoia and the Toyota Tundra and will be available with a twin-turbo V-6 powertrain—offered with and without hybrid assist—rather than the V-8 of the outgoing model. It slots into the Lexus SUV lineup between the flagship LX luxury off-roader and the TX SUV, the latter of which is similar in size but focused more on interior space and on-road refinement.
