2027 Lexus GX 550: What's New, Trims, Specs & Features
The 2027 Lexus GX 550 adds ventilated rear outboard seats as standard on Luxury, Luxury+, and Overtrail+ grades, a meaningful comfort upgrade. This model year carries over the twin-turbocharged 3.4L V6 producing 349 hp and 479 lb-ft of torque from 2026. This page covers every trim, spec, and change as the 2027 GX 550 gets closer to release at Lexus of Riverside in Riverside, CA.
WHAT'S NEW FOR 2027
Two focused updates define the 2027 GX 550. First, ventilated rear outboard seats are now standard on the Luxury, Luxury+, and Overtrail+ grades, a feature that previously required buyers to step up or go without. For passengers on long runs through the Inland Empire heat, that shift matters.
Second, SmartAccess 4-door and tailgate entry is now standard across all six grades, removing an upgrade decision that used to require comparison shopping.
Everything else that made the 2026 GX a benchmark in the luxury body-on-frame SUV segment carries forward intact: the GA-F platform, the twin-turbo V6, full-time 4WD, and the Lexus Safety System+ 3.0 suite.
TRIM LINEUP
The 2027 GX 550 is offered in six grades, each building on the one below it.
GX 550 PREMIUM
GX 550 Premium is the entry point. It delivers NuLuxe-trimmed seating for seven, heated and ventilated front seats, a 14-inch Lexus Interface touchscreen, 12.3-inch digital MID, Triple-Beam LED headlamps, a 10-speaker sound system, wireless Apple CarPlay and Android Auto, and the full Lexus Safety System+ 3.0 suite. Twenty-inch six-twin-spoke alloy wheels with Dark Gray metallic finish are standard.
GX 550 PREMIUM+
GX 550 Premium+ adds a power-folding moonroof with roof rails, Thematic Ambient Illumination, illuminated door sills, a power rear door with kick sensor, and outside mirrors with puddle lamps. Four USB-C ports replace the two found on the base grade.
GX 550 LUXURY
GX 550 Luxury steps up to a 22-inch 12-spoke forged alloy wheel, semi-aniline leather interior, front massaging seats, a 10-way heated and ventilated power driver's seat, heated second-row outboard seats, ventilated second-row outboard seats (new for 2027), a Panoramic View Monitor, power-folding third-row seat, and available Mark Levinson 21-speaker surround sound. Seating configurations include seven-passenger bench or six-passenger captain's chairs.
GX 550 LUXURY+
GX 550 Luxury+ adds Lexus's Dynamic Sky panorama glass roof, a Digital Rearview Mirror, and ventilated second-row outboard seats. The Mark Levinson system is standard here.
GX 550 OVERTRAIL
GX 550 Overtrail is the off-road specialist in the lineup. It seats five across two rows, gains the exclusive 1-inch suspension lift, Electronic Kinetic Dynamic Suspension System (E-KDSS), an electronically locking rear differential, Crawl Control, Multi-Terrain Select, Downhill Assist Control, 18-inch six-spoke alloy wheels with 33-inch all-terrain tires, black utility roof rails, and onboard air compressors. Ground clearance reaches 9.84 inches.
Bi-tone color combinations, including Atomic Silver/Black Roof, Incognito/Black Roof, Nori Green Pearl/Black Roof, and Earth/Black Roof, are exclusive to this grade and Overtrail+.
GX 550 OVERTRAIL+
GX 550 Overtrail+ is the fully loaded off-road configuration, adding ventilated rear outboard seats (standard for 2027), Adaptive Variable Suspension, prewired auxiliary switches, and additional luxury appointments on top of the Overtrail's capability platform.
PERFORMANCE & POWERTRAIN
Every 2027 GX 550 runs the same twin-turbocharged 3.4L V6 paired with a 10-speed Direct Shift Automatic transmission. Output is 349 hp at 4,800-5,200 rpm and 479 lb-ft of torque between 2,000 and 3,600 rpm. The broad torque band makes the GX feel responsive at low throttle inputs, useful both in traffic on the 91 freeway and on loose terrain off it.
Full-Time 4WD is standard across all grades. A Torsen limited-slip locking center differential splits power 50:50 front to rear and is standard on every trim.
Towing capacity reaches 9,096 lbs. on the Overtrail grade and 9,063 lbs. on Premium, Premium+, and Overtrail+ grades (Luxury and Luxury+ vary by seating configuration).
EPA fuel economy is rated at 15 city / 21 highway / 17 combined mpg. The fuel tank holds 21.14 gallons and the engine requires premium 91-octane fuel. Zero to 60 mph takes 6.5 seconds.
The double-wishbone front suspension and four-link rear suspension are tuned for both controlled on-road handling and the wheel articulation needed off-road, with up to 24.45 inches of articulation on the Overtrail grades.
INTERIOR, COMFORT & CARGO
The GX seats seven on Premium, Premium+, Luxury, and Luxury+ grades (or six with optional captain's chairs) and five on the Overtrail and Overtrail+.
Front legroom is 41.18 inches, second-row legroom is 36.73 inches, and third-row legroom measures 31.89 inches. Shoulder room in the second row is 57.17 inches.
All grades come standard with heated and ventilated driver and front passenger seats, a power tilt-and-telescopic steering column, and the Lexus Memory System covering the driver seat, outer mirrors, and steering column.
Heated second-row outboard seats are standard from the Luxury grade up. Ventilated rear outboard seats, new for 2027, are standard on Luxury, Luxury+, and Overtrail+. Front massaging seats are standard on Luxury and above.
Cargo space behind the third row is 10.3 cu ft. Folding the third row opens 40.2 cu ft, and with both rows folded the GX offers 76.9 cu ft (three-row models). The two-row Overtrail/Overtrail+ delivers 90.5 cu ft maximum cargo volume. Two under-cargo storage compartments handle smaller gear.
A 120V / 400-watt AC inverter is standard on all grades, and a cool box is standard on Luxury grades.
Interior trim choices include NuLuxe on Premium through Overtrail grades and semi-aniline leather on Luxury and Luxury+. Color options span Black, Dapple Gray, and Saddle Tan. Overtrail grades offer Black NuLuxe with Olive Ultrasuede accents or Chateau NuLuxe with Olive Ultrasuede accents.
TECHNOLOGY & INFOTAINMENT
A 14-inch HD Lexus Interface touchscreen is standard on every grade. The display uses an anti-reflective coating and a physical volume/power knob at the bottom edge, a practical choice for off-road situations when a steady finger on a touchscreen is difficult.
A 12.3-inch digital Multi-Information Display sits in the driver's sightline. Wireless Apple CarPlay and Android Auto are standard on all grades.
Six USB-C ports are standard on Premium+ through Luxury+; four are standard on Overtrail and Overtrail+. A wireless phone charger is standard on Premium+ through Luxury+ and available on Premium and Overtrail.
The standard 10-speaker premium sound system handles everyday listening. The available 21-speaker Mark Levinson surround sound system (standard on Luxury+, available on Luxury and Overtrail+) uses Quantum Logic Surround technology to deliver consistent sound to every seating position.
Cloud Navigation, Intelligent Assistant voice recognition (activated by saying "Hey Lexus"), and Traffic Jam Assist are all available through the Drive Connect subscription, with a three-year trial included.
A Head-Up Display is available on all grades. Digital Key with SmartAccess Card Key is available on Premium through Overtrail+ and allows the GX to be shared with up to seven additional users through the Lexus app.
Panoramic View Monitor with the Multi-Terrain Monitor four-camera system is standard on Overtrail and Overtrail+ and available on Luxury grades.
SAFETY & DRIVER ASSISTANCE
All 2027 GX 550 grades are equipped with Lexus Safety System+ 3.0 as standard. The suite includes:
- Pre-Collision System with Pedestrian Detection (automatic emergency braking from approximately 7-110 mph)
- Full-Speed Range Dynamic Radar Cruise Control
- Lane Tracing Assist
- Lane Departure Alert with Steering Assist
- Risk Avoidance Emergency Steer Assist
- Proactive Driving Assist
- Road Sign Assist

- Emergency Driving Stop System
Intuitive Parking Assist with Auto Braking and Rear Pedestrian Detection is standard from Premium+ and up.
The Panoramic View Monitor with Multi-Terrain Monitor is standard on Overtrail grades and extends visibility under and around the vehicle using four cameras fed to the 14-inch display.
WHO IT'S FOR / VS THE PRIOR YEAR
The 2027 GX 550 makes the most sense for buyers who want a body-on-frame luxury SUV that can genuinely go off-road rather than just look the part.
The Overtrail and Overtrail+ grades are the right choice for anyone who regularly heads onto trails or unpaved terrain around Southern California, the E-KDSS, locking rear differential, Crawl Control, all-terrain tires, and 9.84 inches of ground clearance form a capable package.
Buyers who prioritize passenger comfort on long highway drives will find the most value in the Luxury and Luxury+ grades, where the new ventilated rear seats join massaging front seats and the optional Mark Levinson system.
Against the 2026 model, the 2027 is not a ground-up redesign. If you already own a 2026 GX, the ventilated rear seats and standard SmartAccess entry are incremental upgrades rather than reasons to trade in. If you are shopping new and rank rear-passenger comfort high, the 2027's changes tip the value toward the Luxury and Overtrail+ grades over their 2026 equivalents.
