The TX is the three-row luxury SUV from Lexus that comes in three versions: gas-powered, hybrid and plug-in hybrid. The 550+ is the plug-in hybrid. It serves as a family-friendly option for those who want a luxury vehicle with seating for six that provides 33 miles of electric-only driving and good fuel economy.

The TX was added to the Lexus line-up for the 2024 model year. It’s the brand’s first three-row SUV on a car-based platform rather than the truck-based, body-on-frame platform on the GX and LX models. The TX uses Toyota’s GA-K unibody platform, shared with the Toyota Grand Highlander for better handling and ride quality. For 2026, the TX 550h+ gets only minimal changes.
The 2026 TX 550h+ comes in only one trim: Luxury. It starts at $79,510. All-wheel drive is standard. There’s room for six passengers, with standard captain’s chairs in the second row.
The 2026 TX has an all-electric range of 33 miles. It comes standard with a Level 1 vehicle charging cable for 120V outlets and is equipped with a J1772 socket for at-home and public charging. Lexus says the TX 550h+ can be fully charged in about three hours with a 240V (Level 2) charger.
For many drivers, 33 miles is enough for daily use without the need to burn gas. I only used about a quarter tank of gas during my week with the TX 550h+.
The 2026 TX 550h+ is powered by a 3.5-liter V6 paired with electric motors. Total output is 404 horsepower. The transmission is a continuously variable transmission.
The 2026 TX 550h+ prioritizes comfort over sporty handling, which is what you expect in a vehicle weighs about 5,400 pounds. But it’s not dull to drive. The electric motors provide instantaneous torque from a stop, and then the V6 kicks in as needed. Lexus says the TX 550h+ can go from zero to 60 mph in 5.9 seconds, which is quick for a three-row crossover. The switch from all-electric to hybrid operation occurs smoothly and is barely noticeable. The unibody construction and suspension make for a silky-smooth ride. You’ll barely notice bumps and rough roads. While the TX 550h+ feels planted in most driving scenarios, there is noticeable body lean when cornering, especially if you’re doing it with some speed.
Fuel efficiency is good for a three-row SUV. EPA ratings for the TX 550h+ are 29 mpg city, 28 mpg highway and 29 combined in gasoline/hybrid mode, and 76 MPGe (miles per gallon equivalent) in combined driving in electric/hybrid mode. I got 27 mpg during my week with a mix of city and highway driving. Premium fuel is recommended.
The cabin is spacious and comfortable with space for adults in all three rows. Materials are nice, but the cabin isn’t opulent; rather, it has an understated look. Some, though, may feel that the cabin isn’t that much more upscale than the higher trims of its cousin, the Toyota Grand Highlander. A panoramic glass roof is standard for 2026, giving the cabin an airy feel. The first two rows boast plenty of leg- and headroom for taller adults with comfortable and supportive seats. Even the third row is roomy and comfy enough for adults, a rarity in most three row SUVs. A large 14-inch touchscreen is on the center stack.
Standard features include remote access, push-button start, rearview camera, multi-zone climate control with interior air filter, semi-aniline leather-trimmed upholstery, black grained trim, heated front seats, ventilated front seats, 10-way power-adjustable driver’s and front passenger’s seats with four-way power lumbar adjustment, memory system for driver’s seat, power tilt-and telescoping steering wheel, heated leather-trimmed steering wheel and shift knob, steering wheel paddle shifters, heated and ventilated second-row captain’s chairs, 50/50-split power-reclining third row seats, 12.3-inch information display, infotainment system with 14-inch high-definition touchscreen, 12-speaker Lexus premium audio system, satellite radio, voice commands, wireless Android Auto and Apple CarPlay, seven USB ports, Bluetooth, wireless device charging, Wi-Fi hotspot, thematic ambient illumination, rear manual sunshades, rain-sensing windshield wipers, adaptive headlights with automatic high beams, cornering headlights, headlamp washers, and a panorama glass roof.
Available features include a digital key, surround-view camera system, head-up display, digital rearview mirror, Mark Levinson 21-speaer premium surround sound audio system, 120V/1,500-watt power outlet, windshield wiper de-icer, and roof rails.
Standard driver assistance technologies include automatic emergency braking, adaptive cruise control, lane departure warning with steering assist, lane tracing assist, blind-spot monitoring, Proactive Driving Assist, pedestrian detection, rear pedestrian detection, road sign assist, parking assist with auto braking, and safe exit assist (prevents doors from opening if traffic or cyclists are detected).
Available driver assistance technologies include Traffic Jam Assist, front cross-traffic alert, and advanced park with remote park.
The TX 550h+ gets the latest version of the Lexus Interface infotainment system with cloud navigation. It looks impressive with its large 14-inch touchscreen. Graphics are sharp and easy to see and reach. But the menus aren’t always logically arranged so there is a learning curve. And the system doesn’t always respond in a snappy fashion to voice commands.
The TX 550h+ has 20.2 cubic feet of storage behind the third row, 57.4 cubes with the third row folded, and 97 cubes with the second and third rows folded. Just push a button and the seats go up or down. A tonneau cover and power liftgate with kick sensor are standard.
The good:
Smooth, cushy ride
Brisk acceleration
33 miles of all-electric range
Many standard and available features and tech
Standard wireless Android Auto and Apple CarPlay
Impressive passenger and cargo space
Even the third row is spacious enough for adults
The not-so-good:
Expensive starting price near $80,000
Cabin not as luxurious as the price would suggest
Infotainment system could use updated menus

Bottom line:
The 2026 Lexus TX 550h+ is comfortable and extremely spacious with plenty of room for passengers and cargo. Even the third row is adult friendly. The ride is smooth and comfortable, and the TX 550h+ has an all-electric range of 33 miles and good fuel economy, meaning most drivers will not need to visit the gas station often. The biggest drawback is the high price. For families wanting a large luxury SUV that’s available as a plug-in hybrid, and have 80-grand to spend, the TX 550h+ is worth consideration.
