Electrification has been a cornerstone of Lexus’s strategy for quite some time, to the point that virtually every model in the lineup offers a hybrid powertrain or is fully electric. The exception? The GX 550, which soldiers on with a gasoline-only engine. That could be about to change, if a recent move by the automaker is any indication.
Lexus filed a trademark for the GX 550h name on March 16, 2026, simultaneously in several countries, including Canada
The GX 550 is currently the only Lexus model not available with an electrified powertrain
A hybrid powertrain could cut fuel consumption by as much as 30%
The move in question is the submission of a name registration to trademark authorities. The name: GX 550h. Filed on March 16.
The Missing Hybrid Link
The current GX 550 was never meant to win any efficiency awards. Its twin-turbocharged 3.4-litre V6 and 349 horsepower come with a combined fuel consumption rating of approximately 13.8 L/100 km, a figure that’s a harder sell today than it was 15 years ago.
For a brand that has long positioned itself as a pioneer in luxury electrification, the GX stands out like a sore thumb. Which is a shame, because since its redesign a few years back, the GX is arguably the best-looking vehicle in the entire Toyota/Lexus family.

A hybrid variant would be a welcome addition. If Lexus goes with the i-Force Max powertrain already found in several Toyota Group models (4Runner, Tundra, and Land Cruiser), that turbocharged 2.4-litre four-cylinder could bring average fuel consumption below 10 L/100 km. That’s a 30% to 40% improvement, which is nothing to sneeze at.
To be fair, fuel economy isn’t what drives most GX buyers at this price point. But it certainly wouldn’t hurt.
The other option on the table is the hybridized V6 from the LX 700h, with 457 horsepower and 583 lb-ft of torque. More power, but fewer gains at the pump.
Patience
Whether this trademark filing translates into an actual production model remains to be seen. A name registration guarantees nothing. That said, the fact that the application spans multiple countries does make things a bit clearer.
One thing is certain: Lexus wants to claim that every single model in its lineup offers an electrified powertrain. The GX is the last piece of that puzzle.
