• Lexus reveals updated LX with new hybrid powertrain
  • Chassis reinforcements to support hybrid powertrain improve steering and stability
  • Updated Lexus LX also gains rugged Overtrail grade

Lexus has introduced an update to the LX for the 2025 model year and included among the changes is a new hybrid powertrain, marking the first time the Lexus full-size SUV nameplate has featured electrification.

The hybrid powertrain is featured in a new flagship model dubbed the LX 700h, and consists of a twin-turbocharged 3.5-liter V-6 paired with an electric motor sitting between the engine and the LX's standard 10-speed automatic transmission. Drive goes to all four wheels via a four-wheel-drive system with a 2-speed transfer case.

Unlike other Lexus hybrids, the powertrain in the LX 700h features a conventional starter motor and alternator, instead of relying solely on the hybrid system's electric motor to handle those tasks. This was done, Lexus said, to ensure the vehicle can still function in the event of the hybrid system failing, which is important when you're out on a distant trail.

Lexus hasn't said how much horsepower is produced as development is ongoing, but the same powertrain features in Toyota's Tundra and Sequoia models, where it produces a combined 437 hp. Toyota's pickup and SUV are close cousins of the LX, including sharing the same GA-F body-on-frame platform.

The current LX was introduced for the 2022 model year and at present is offered exclusively in LX 600 guise. This model comes with a twin-turbocharged 3.4-liter V-6 good for 409 hp.

Other changes made to the LX for 2025 include a new Overtrail grade. Similar to the Overtrail grade offered in the smaller GX, the LX Overtrail grade adds front and rear differential locks, and 18-inch wheels with all-terrain tires (another first for an LX). It also adds unique design details like gloss black exterior accents, an available Moon Desert exterior paint finish, and an available interior color and trim theme called Monolith.

Lexus said it also made some reinforcements to the chassis to accommodate the hybrid powertrain, which had the added benefit of improving overall rigidity and as a result improved steering feel and handling stability. The engine mounts were reinforced to handle the increased weight of the powertrain. Lexus also introduced a new cross member and relocated the spare tire to accommodate the battery beneath the rear floor. Additionally, the standard 12-volt auxiliary battery was shifted to the side of the rear deck, from its former home in the engine bay, with a new brace for the battery further enhancing rigidity. The radiator support was also made more robust, and a sturdier instrument panel brace was added as well.

Lexus hasn't announced plans for the updated LX in the U.S. yet but a launch later this year or early next is likely. The automaker said a phased rollout across various regions is scheduled to begin late this year.
