LEXUS GX 550

The 2026 Lexus GX 550 in Japan is a body-on-frame luxury SUV on the GA-F platform, offered in two JDM grades: the off-road-focused OVERTRAIL+ and the luxury-focused version L. Both share the 3.4L V6 twin-turbo (V35A-FTS) with 349 hp (260 kW / 354 PS) and 650 Nm (479 lb-ft), paired with a Direct Shift-10AT 10-speed automatic and full-time 4WD.

Variants

Both grades use the same GA-F ladder-frame architecture and the same twin-turbo V6 powertrain; the key difference is that OVERTRAIL+ is tuned for trail use while version L emphasizes luxury, seating capacity, and convenience equipment.

Dimensions

The OVERTRAIL+ gains an approximately 1-inch suspension lift, which raises minimum running ground clearance to 9.84 inches (250 mm).

Available Colors

Lexus states that the 2026 GX offers the above exterior colors depending on grade, and that the Overtrail grades receive exclusive bi-tone exterior combinations.

Powertrain Detail

• Engine: 3.4L V6 twin-turbo, engine code V35A-FTS.
• Output:349 hp (260 kW / 354 PS) at 4,800 rpm and 650 Nm (479 lb-ft) at 2,000 rpm.
• Turbocharger configuration: Lexus identifies the engine as a twin-turbo V6; the provided results do not explicitly confirm single-scroll or twin-scroll compressor architecture, but it is clearly a pair of turbochargers on the V35A-FTS family.
• Intercooling: The provided results do not explicitly state intercooler type, though the engine is a modern forced-induction V6 used in the GX lineup.
• Transmission:Direct Shift-10AT 10-speed automatic.
• Drive modes: Lexus GX global equipment includes selectable drive modes; the provided results specifically reference terrain-oriented modes on off-road grades and general model-family drive-mode selection, but do not publish the full JDM mode list in the search results.
• Fuel economy: The provided results do not show a public JDM JC08 or WLTC figure for the Japan-spec GX 550. U.S. market testing in the results shows approximately 17 mpg combined for an Overtrail+ example, which is not a JDM certification value and should be treated only as an outside-market reference.

Off-Road Geometry & Capability

• E-KDSS behavior: Lexus says E-KDSS provides a balance between off-road drivability and on-road handling stability by managing suspension coupling to improve articulation when needed and stable body control on-road.
• What it disconnects/reconnects: In GX usage, E-KDSS is associated with electronically managed stabilizer-bar coupling; the provided results do not spell out the mechanical state transitions in JDM wording, so this should be treated as the standard Lexus E-KDSS articulation/stability function described by Lexus.
• Crawl Control: Included on the off-road-focused grade; the provided results confirm presence but do not publish JDM speed increments.
• Multi-Terrain Select modes: Off-road GX references in the search results identify terrain-select capability but do not publish a full JDM mode matrix. On the broader GX family, modes commonly associated with this system include mud, sand, rock, snow, and auto-style calibration, but the exact JDM list is not explicitly documented in the provided results.
• Multi-Terrain Monitor: GX luxury/off-road equipment includes camera views around the vehicle, and some GX configurations provide underbody-oriented visibility for trail placement; the provided results confirm the camera system class but not every view label in JDM form.
• Rear differential lock: Lexus states the electronically controlled locking rear differential is activated by a console-mounted switch and splits power evenly between the left and right rear wheel to help both rear wheels turn at the same speed.

Lexus Safety System+ and ADAS

• Pre-Collision System with pedestrian detection and cyclist detection is part of the GX family safety suite; the search results also indicate forward emergency braking functionality in model-family listings.
• Dynamic Radar Cruise Control with full-speed range capability is part of the GX safety package structure in this generation.
• Lane Tracing Assist helps keep the vehicle centered in lane when cruise control is active.
• Lane Departure Alert provides warning and lane-departure support.
• Road Sign Assist recognizes major road signs and displays them to the driver.
• Proactive Driving Assist is part of Lexus Safety System+ on modern GX applications where fitted.
• Blind Spot Monitor is shown in GX model-family equipment listings.
• Rear Cross Traffic Alert/Brake is shown in GX model-family equipment listings.
• Panoramic View Monitor is fitted on higher-spec GX variants; off-road-oriented GX equipment can include enhanced camera coverage for low-speed maneuvering and obstacle placement.
• Safe Exit Assist is part of Lexus’s current active-safety ecosystem on premium models.
• Intelligent Clearance Sonar is associated with parking/low-speed collision avoidance equipment on the GX family.
• Automatic High Beam is included in the active-lighting assistance suite.
• Traffic Jam Assist / Advanced Drive: U.S. market GX references show Traffic Jam Assist on some variants, but the provided results do not confirm a Japan-market Lexus Teammate / Advanced Drive equivalent for the GX 550 in JDM specification.

Towing, Payload, and Utility

• Towing capacity: The broader 2026 GX 550 lineup is rated at 6,500 lb (2,948 kg) in U.S. market materials, and the JDM GX 550 uses the same core platform and powertrain; however, the provided results do not publish a Japan-market towing figure, so the U.S. figure is the closest documented equivalent in the search results.
• Payload: Not publicly published in the provided results.
• Utility equipment: Power rear door, roof rack availability, tow hitch equipment, and cargo-management accessories appear in market listings for the GX family.
