2025 Lexus LX revealed: Luxury LandCruiser gets twin-turbo V6 hybrid

The Lexus LX range will grow in 2025 to include the luxury SUV’s first-ever hybrid powertrain, as well as a rugged Overtrail trim.

Lexus has previewed the updated 2025 LX range, with its local arm confirming the LX 700h hybrid and Overtrail models “will be considered for when the updated LX comes to Australia”.

The company says it will share further news on the updated LX “in due course”.

Lexus is calling the LX 700h’s powertrain a “high-performance parallel hybrid” that will offer “the reliability and durability customers expect when heading deep into bush or snow”.

It’ll be the first hybrid Lexus with a wading depth comparable to combustion-powered off-roaders, at 700mm, with the hybrid battery sitting within a specially designed waterproof casing under the rear floor.

The AC inverter, located under the centre console, is also waterproof. It allows for external power supply of up to 1500W or 2400W, depending on the region.

Lexus also says the LX 700h will be its first parallel hybrid to feature both an alternator and a starter motor, reducing reliance on the electric motor.

This enables engine ignition independent of the electric motor, with the alternator powering the 12V auxiliary battery.

It also allows functions like ride height adjustment and Active Traction Control 2 (A-TRAC) to continue to operate even when the electric motor isn’t in use.

The LX 700h packs a 3.4-litre twin-turbo petrol V6 and 10-speed automatic like the LX 600, but integrates the motor/generator with a clutch in between the engine and the transmission.

It continues to feature a full-time four-wheel drive system and a low-range transfer case.

The LX 700h will run on purely electric power at low-speed driving, and Lexus says there’s a use-case for this beyond crawling through carparks.

It says that in conjunction with the various terrain modes on offer, the use of pure electric power can help in situations where precise throttle control is required such as on rocky trails or in deep snow.

Lexus has also released prototype specifications of the 2025 LX 700h:

It’s identical in exterior dimensions to existing non-F Sport LX models, though weight is up slightly; the existing LX lineup ranges in kerb weight from 2630kg to 2690kg.

Lexus says the LX’s body-on-frame GA-F underpinnings have been upgraded to accommodate the hybrid powertrain, with a third crossmember installed to support the extra length and weight of the powertrain, as well as upgraded rear engine mounts.

Lexus also says redesigned mounting cushions attaching the upper body help improve torsional rigidity and reduce vibration, making the cabin quieter.

The introduction of the LX Overtrail follows the arrival of the new-generation GX off-roader, which debuted the Overtrail name.

The Overtrail is available only in a five-seat configuration, but across all three of the LX’s powertrains.

It adds locking front and rear differentials, 18-inch alloy wheels in all-terain tyres, and a 30L auxiliary fuel tank (bringing capacity to 110L).

Cosmetic changes include a black grille, as well as black trim for the bumpers, wheel arches, mirrors, door handles, and roof rails.

It also features a unique Moon Desert exterior colour.

Beyond the new LX 700h and Overtrail variants, the core LX range is also getting some tweaks as part of the 2025 update.

A 12.3-inch digital instrument cluster replaces the existing 8.0-inch unit on all variants, while the LX uses the latest Lexus Safety System + suite of active safety and driver assist technology which includes features like Safe Exit Assist, a driver monitoring camera, and the Emergency Driving Stop System (EDSS).

Lexus currently offers the LX, a more luxurious cousin to the Toyota LandCruiser 300 Series, with a choice of two powertrains.

The LX 600 uses a twin-turbo 3.4-litre petrol V6 producing 305kW of power and 650Nm of torque, while the LX 500d uses a twin-turbo 3.3-litre diesel V6 with 227kW and 700Nm.
