The 2026 Lexus GX 550 updates what a luxury SUV can achieve, pairing legendary go-anywhere capability with sophisticated refinement. Whether you're drawn to the rugged appeal of trail-ready adventure or the polished elegance of executive comfort, the GX 550 lineup offers six distinct grades designed to match your lifestyle. From the foundational Signature trim to the flagship Executive grade, each configuration delivers the power, technology, and craftsmanship that define the Lexus experience.
Built on the robust GA-F platform and powered by a 3.4 L twin-turbo V6 engine producing 349 horsepower and 479 lb-ft of torque, the GX 550 pairs performance with versatility. Full-time four-wheel drive, a Torsen limited-slip locking rear differential, and a 4,111 kg (9,063 lbs) towing capacity ensure this SUV is ready for any challenge. With six grades to choose from, understanding which trim aligns with your priorities is essential to finding your ideal match.
GX 550 Signature: The Foundation of Adventure
The Signature grade serves as the entry point to the GX 550 lineup, delivering a seven-passenger configuration with essential luxury and capability. This model features NuLuxe upholstery, heated and ventilated front seats, and a driver's seat memory system linked to exterior mirrors and a heated steering wheel on a power-adjustable column. The 20-inch alloy wheels provide a balanced blend of on-road comfort and off-road readiness.
Technology highlights include the Lexus Interface with Service Connect, Safety Connect, and Remote Connect, displayed on a 14-inch HD touchscreen. A 10-speaker audio system, wireless Apple CarPlay and Android Auto compatibility, and a 12.3-inch full-colour multi-information display keep drivers connected and informed. The power moonroof with sunshades and power back door add convenience to daily use.
New for 2026, the Signature grade now includes Lexus Safety System+ 3.0 Extended, featuring Traffic Jam Assist, Front Cross Traffic Alert, Driver Monitor, and Lane Change Assist. Additional safety systems include Parking Support Alert with Brake (object and vehicle detection), Blind Spot Monitor with Rear Cross Traffic Alert, and a backup camera with Back Guide Monitor. A digital key for the front two doors plus the back door enhances security and access.
GX 550 Premium: Elevated Comfort and Connectivity
The Premium grade builds on the Signature foundation with upgrades in comfort, technology, and convenience. This seven-passenger model adds power-folding third-row seating (50/50 split) and heated rear seats, making it ideal for families seeking flexibility. The rear door kick sensor enables hands-free operation when your arms are full of gear or groceries.
Exterior enhancements include fog lamps, cornering lamps, and 20-inch machined alloy wheels. Silver chrome mouldings and piano black painted exterior details refine the GX's commanding presence. Acoustic front side glass reduces cabin noise, while a multi-colour ambient lighting system (64 colours) creates a personalized atmosphere inside.
Technology advances include the addition of Drive Connect to the Lexus Interface suite, expanding navigation and cloud-based services. The digital key now covers all four doors plus the back door, and the Panoramic View Monitor system provides comprehensive visibility. Aluminum scuff plates, parking support alert with brake (now including pedestrian detection), and a head-up display complete the Premium experience.
GX 550 Overtrail: Purpose-Built for Off-Road Exploration
The Overtrail grade transforms the GX 550 into a five-passenger off-road specialist. This model features the Lexus Electronic-Kinetic Dynamic Suspension System (eKDSS), which actively manages body roll and suspension articulation for superior trail performance. An off-road-tuned Adaptive Variable Suspension system with five driving modes allows drivers to optimize performance for terrain conditions.
Distinctive 18-inch alloy wheels wrapped in 33-inch all-terrain tires provide high traction and ground clearance. A rear differential lock, front and transmission skid plates, and front tow hooks prepare the Overtrail for serious exploration. The Multi-Terrain Monitor with underfloor view helps drivers navigate obstacles with confidence.
Practical features include bridge-type roof rails, black wheel arch mouldings, and cornering and fog lamps. The Lexus Interface includes Service Connect, Safety Connect, Remote Connect, and Drive Connect. Four USB charging ports, 2-zone automatic climate control, and rear side window privacy glass maintain comfort during extended adventures. The Overtrail's two-row configuration maximizes cargo space while preserving the rugged capability that defines this grade.
GX 550 Luxury: Premium Audio and Refined Appointments
The Luxury grade elevates the Premium model with 22-inch forged alloy wheels and semi-aniline leather upholstery in the first and second rows. Power-adjustable front seats now include a massage feature, transforming long drives into relaxing experiences. Rear sunshades and a digital rear view mirror (new for 2026) enhance passenger comfort and driver visibility.
The standout feature of the Luxury grade is the 21-speaker Mark Levinson premium audio system, delivering concert-quality sound throughout the cabin. This system transforms the GX into a mobile listening room, whether you're enjoying music, podcasts, or navigation prompts. Illuminated aluminum scuff plates add a sophisticated welcome each time you enter.
All Premium-grade technology and safety features carry over, including the Panoramic View Monitor, Intuitive Parking Assist with Auto Braking and Rear Pedestrian Detection, and the comprehensive Lexus Interface connectivity suite. The Luxury grade maintains seven-passenger seating with power-folding third-row seats, making it a strong choice for families who prioritize comfort and audio quality.
GX 550 Executive: The Pinnacle of Six-Passenger Luxury
The Executive grade is the flagship expression of GX 550 refinement. This six-passenger configuration replaces the second-row bench with captain's seats, creating a first-class travel experience for all occupants. The fixed dimming panoramic roof floods the cabin with natural light while maintaining thermal comfort.
Exclusive features include a cooling box for beverages, automatic running boards for effortless entry and exit, and a five-setting drive mode select system that fine-tunes performance for various conditions. The Executive builds on the Luxury grade's foundation, retaining the 22-inch forged alloy wheels, semi-aniline leather upholstery, massage-equipped front seats, and Mark Levinson audio system.
The Executive's second-row captain's seats offer superior comfort for passengers, making long journeys feel effortless. Rear sunshades, heated rear seats, and the multi-colour ambient lighting system transform the GX into a luxurious mobile sanctuary. The Executive is designed for drivers who demand the highest level of comfort and capability in equal measure.
GX 550 Overtrail+: Maximum Off-Road Capability with Premium Comfort
The Overtrail+ grade pairs the trail-ready features of the Overtrail with the premium comfort and technology of the Luxury grade. This five-passenger model retains the eKDSS suspension, Adaptive Variable Suspension with five driving modes, 18-inch wheels with 33-inch all-terrain tires, rear differential lock, and Multi-Terrain Monitor.
Comfort and convenience upgrades include a driver's seat memory system linked to a power-adjustable steering column and exterior mirrors, heated rear seats, and additional power adjustments plus massage function on front seats. The 21-speaker Mark Levinson audio system ensures high-quality sound even on rough terrain.
Practical additions include an onboard air compressor for inflating tires after trail use, a cooling box, and a power back door with kick sensor. Acoustic side front glass, illuminated aluminum scuff plates, rear sunshades, and a head-up display maintain the premium experience. The digital key covers all four doors plus the back door, and Parking Support Alert with Brake includes pedestrian detection. The Overtrail+ is the ideal choice for adventurers who refuse to compromise on comfort.
