After almost thirty years in the market, the Lexus LX has finally embraced electrification. The fourth-generation luxury SUV introduces a new 700h variant, which sits at the pinnacle of the lineup. Unlike many hybrid vehicles that have downsized in recent years, the LX 700h retains its twin-turbo 3.5-liter V-6 engine and incorporates a parallel hybrid system. A motor generator with a clutch is integrated between the combustion engine and the 10-speed automatic transmission.

Unlike previous Lexus models with a parallel hybrid setup, the LX 700h features both an alternator and a starter. These components are essential in case the hybrid system fails, ensuring the SUV can continue operating solely on the gas engine. The alternator powers the 12V auxiliary battery, while the starter provides independent engine ignition. Even in such a scenario, the LX 700h's low-range mode, traction control, and the air suspension's Active Height Control system remain functional.

To maintain its off-road capabilities, Lexus has designed a waterproof structure to protect the hybrid battery, which is located at the rear floor with a waterproof tray divided into upper and lower sections. Despite the addition of electric components, the SUV retains a fording depth of 27.5 inches (70 centimeters). The new Overtrail trim includes standard front and rear differential locks, along with all-terrain tires, enhancing its off-road prowess.

While power figures for the 700h have not been disclosed, the LX 600 boasts 409 hp and 479 lb-ft (650 Nm) of torque. The 700h weighs 6,128 pounds (2,780 kilograms) for the Middle East specification, compared to the base LX in the US, which weighs 5,665 lbs (2,569 kg), rising to 5,945 lbs (2,697 kg) for the Ultra Luxury model.

Beyond the hybrid setup, the LX 700h features stronger engine mounts, a new cross member, and a repositioned spare tire to accommodate the battery. The 12V auxiliary battery is now located at the side of the rear deck, and the radiator support is more rigid. Additionally, the LX revision includes a new 12.3-inch digital instrument cluster, redesigned front seats, and fast-charging support for the wireless pad. The 700h also introduces the Electro-Shiftmatic system, enhancing the shift knob's tactile feel and usability.

The updated LX, including the new 700h, will be available starting later this year. While pricing for the hybrid variant has not been announced, it is expected to command a premium over the LX 600, which starts at $93,915 and reaches up to $134,490 in the US.
