The all-new GX SUV has an entry level MSRP of $64,250 up to $81,250. GX is expected to arrive at Lexus dealerships in early 2024 after it starts production at the Tahara plant in Japan. The 2024 GX is offered in six grades: Premium, Premium+, Luxury, Luxury+, and in a first for Lexus, Overtrail and Overtrail+. A 3.4-liter twin-turbo V6 produces 349 horsepower; 479 lb.-ft. of torque with a 10-speed Direct Shift Automatic Transmission. This results in an slightly improved EPA-estimated highway fuel economy rating of 21 MPG. Towing capacity has increased to 8000 lbs. for Premium, Premium+ and Overtrail grades with the standard tow hitch. A hybrid powertrain will be introduced in the US. at a later date.

The 2024 GX, along with the Toyota Land Cruiser, is based on the so-called GA-F platform introduced on the current-generation LX 600 sedan. This strong and lightweight ladder frame increases body rigidity and improves on-road handling. This platform is claimed to be engineered to withstand twisting off-road forces, while maximizing suspension performance, creating stable wheel articulation and consistent tire contact, all while maintaining in-cabin stability. This strengthened frame also allows owners to carry their Lexus dealer optional accessories and gear, such as rooftop tents, recovery kits and such available through the Associated Accessory Parts (AAP) Program.
