When Lexus unveiled the gas-powered third-generation GX in the U.S. in June 2023, it confirmed that a hybrid variant will follow. DeJuan Ross, Group Vice President and General Manager, Lexus Division, Toyota Motor North America, announced the electrified variant at the world premiere:
We’re thrilled to see how our off-road enthusiasts put the GX to work. And to continue our electrification strategy, down the road, GX will adopt a hybrid powertrain.

The first-ever Lexus GX Hybrid is available internationally, as the ‘Lexus GX 550h.’ While Lexus hasn’t provided a timeline for its U.S. release, it could arrive here later this year for MY2026.
While we keep an eye on future announcements, here are six things to know about the upcoming hybrid SUV:
Single-motor Hybrid powertrain
In China, where the variant is on sale, the Lexus GX Hybrid has a single-motor hybrid system that combines the T24A-FTS 2.4-liter turbocharged gas engine and a permanent magnet synchronous motor at the front. The gas engine produces 207 kW (277 hp) and 430 Nm (317 lb.-ft.) of torque, and it is paired with an 8-speed automatic transmission. The electric motor generates 40 kW (54 hp) and 250 Nm (184 lb.-ft.) of torque. The two drive units give the vehicle a combined power of 243 kW (326 hp).
Mechanical 4WD system
Lexus uses a mechanical 4WD system in the GX Hybrid, not an eAWD system like in the unibody TX Hybrid. Thanks to its full-time 4×4 system with a Torsen limited-slip center locking differential and a two-speed transfer case with high/low range, it possesses superior off-roading capability.
Electronic locking rear differential
An electronic locking rear differential is available in the Lexus GX Hybrid internationally, but in the U.S. it should likely be part of the standard equipment. It can split the power 50/50 to the rear wheels to enhance traction control in challenging terrains.
As speedy as the gas model
The Lexus GX Hybrid accelerates from 0 to 100 km/h (0 to 62 mph) in 8.5 seconds, 1.5 seconds slower than the V6-powered gas model. However, it can achieve the same top speed as the latter – 175 km/h (109 mph).
External power supply system
An AC 220-volt, 1500-watt power outlet allows customers to utilize the Lexus GX Hybrid’s traction battery pack as a mobile power station. When traveling, say on a camping trip, they can power their electronic goods through the energy stored in this battery pack. The external power supply system can be useful even at home, during power outages and natural disasters.
Two seating layouts
Lexus manufactures the electrified GX in a regular 5-seat version (2+3 seating layout) as well as a more family-friendly 6-seat version (2+2+2 seating layout), and it remains to be seen if both configurations are offered here in the U.S. The battery pack is beneath the floor in the rear, positioned just above the third-row seats in the 6-seat version.
