Tweaked Engine: 3.4-L Twin Turbo V6 and Direct Shift-10AT

The GX comes standard with a twin-turbocharged 3.4L V6 engine paired with a 10-speed Direct Shift Automatic Transmission. The EPA-estimated highway fuel economy rating is 21 MPG. The twin-turbo V6 produces 349 horsepower, outperforming the previous generation V8’s 301 horsepower, and torque output also rises to 479 lb.-ft. Towing capacity is up to 9063 lbs. for Premium, Premium+, Overtrail+ grades and 9096 lbs. for the Overtrail grade with the standard tow hitch receiver.

The 2026 Lexus GX 550 Overtrail and Overtrail+ have standard Electronic Kinetic Dynamic Suspension System (E-KDSS) that provides a balance between off-road drivability and on-road handling stability. This system locks and unlocks the front and rear stabilizer bars to assist with control and greater wheel articulation. Depending on driving conditions, speed, steering input and the Multi-Terrain Select (MTS) setting chosen by the driver, the system can independently lock or unlock the front and rear stabilizer bars as needed.

Crawl Control can be engaged when the vehicle is in low range (L4) and allows the GX to move forward or in reverse at one of five-driver selected low speed settings. Crawl Control manages engine output and hydraulic braking pressure to help reduce tire slippage and optimize chassis behavior. The GX has up to a 26-degree approach, 24-degree breakover and 21-degree departure angles.

The Multi-Terrain Select system is designed to provide optimized drive power, hydraulic brake pressure and suspension control according to the selected mode. L4 has four modes: Auto, Sand, Mud and Rock. H4 has five modes: Auto, Dirt, Sand, Mud and Deep Snow. When MTS is on, the Multi-Terrain Monitor is engaged to assist the driver with increased visibility under and around the vehicle when driving off-road. The Multi-Terrain Monitor uses four cameras within the Panoramic View Monitor System (PVM) to transpose underfloor, front, side and rear-view camera images shown to the 14-inch display, allowing the driver to check road conditions, blind spots and distance between obstacles.

The GX has the driver-focused cockpit design also seen in the RX and RZ. A low, horizontal instrument panel design carries into the dash. It is said “to provide a clean, open space that seamlessly connects the available Head-Up Display (HUD) to the center where the standard 14-inch Multimedia Touchscreen Display with Lexus Interface technology can be found. Physical dials for frequently used controls such as air conditioning and audio volume remain, and all available off-road controls are concentrated near the gear shifter to help minimize potential driver distraction. The GX comes standard with wireless Apple CarPlay® and Android Auto™ compatibility, as well as a digital 12.3 Multi-Information Display (MID).”
