Lexus has introduced its new large three-row crossover SUV, the TX, to take its place above the RX. This fresh model is built on the same platform as the Toyota Grand Highlander but outshines it with added features, superior interior materials, a unique exterior design, and an optional plug-in hybrid powertrain. Despite these enhancements, the TX will be exclusively manufactured in left-hand drive for the North American market and won't be available in Australia.

The Lexus TX is constructed on the TNGA-K platform, which also serves as the foundation for the Toyota Grand Highlander and a selection of smaller SUVs, including the Lexus NX, Lexus RX, Toyota RAV4, and Toyota Kluger.

The automaker has affirmed that the TX will come with three powertrain options, encompassing a hybrid and plug-in hybrid choice.

Three engines will power the TX: a 2.4-liter turbocharged four-cylinder petrol in the TX350, the same engine with hybrid support in the TX500h, and a 3.5-liter V6 in the TX550h+ plug-in hybrid.

With options for either front or all-wheel drive, the TX350 produces 205kW and 430Nm, edging out the Grand Highlander's 198kW/420Nm. It pairs with an eight-speed automatic transmission and boasts a claimed fuel economy of 11.2 liters per 100km.

The all-wheel-drive TX500h F Sport Performance churns out 273kW and 555Nm. This power is matched with a six-speed auto and a claimed fuel consumption of 9.8L/100km.

The top-tier 2.4-liter TX550h+ plug-in hybrid merges a 3.5-liter non-turbo V6 with electric motors to achieve a combined output of 303kW, coming close to the LX600 4WD's 3.5-liter twin-turbo V6. The plug-in hybrid model is paired with a continuously-variable automatic transmission and all-wheel drive. It delivers a claimed fuel use of 7.8L/100km, and can run up to 53km solely on electric power.

The TX500h and TX550h+ are equipped with Lexus' Direct4 all-wheel-drive system as standard. This technology dynamically distributes power for maximum traction during acceleration and around corners. The TX500h F Sport Performance uniquely features rear-wheel steering to improve maneuverability at low speeds and stability at high speeds.

The interior of the TX houses a 14.0-inch touchscreen infotainment system, with options for a 12.3-inch digital gauge cluster and a head-up display. The cabin has an elegant yet practical design, offering ample storage spaces, a variety of charging ports, and power outlets. Three interior colors are available: Peppercorn, Birch, and Black, and trim levels range from base to Premium, Luxury, and the RX500h F Sport Performance.

The Lexus TX dimensions are 5156mm in length, 1981mm in width, and 1780mm in height, with a 2949mm wheelbase, making it considerably larger than the Lexus RX.

Unlike the RX, the TX provides three rows of seating, with 569 liters of boot space even with the third row upright, expanding to 2746 liters with the third and second rows folded down.

Customers can choose from alloy wheels ranging from 20 to 22 inches, and seven exterior colors and three interior colorways.

When it comes to safety, the TX doesn't hold back. It features autonomous emergency braking, pedestrian detection, lane departure alert with steering assist, Lane Tracing Assist, Proactive Driving Assist, adaptive cruise control, and traffic sign recognition. The TX also offers optional parking assist and subscription-based traffic jam assist.

With ample space and well-appointed interiors, the TX is set to cater to the needs of large families and adventure enthusiasts alike. It's poised to shake up the SUV market with its unique blend of luxury, practicality, and innovative tech.

The dimensions of the Lexus TX, measuring 5156mm long, 1981mm wide, and 1780mm tall, with a 2949mm wheelbase, make it significantly larger than the Lexus RX. This size difference is most noticeable in the TX's additional third-row seating, making it a practical option for those needing more space. When all seats are in use, the boot offers a generous 569 litres of space, which extends to a cavernous 2746 litres with the third and second rows folded down.

The TX is set to roll out on 20 to 22-inch alloy wheels, available in a range of seven vibrant exterior colours. Inside, customers can choose from three tasteful colourways, adding a touch of personal style to the vehicle.

Safety is a prime focus for the Lexus TX. It's equipped with a suite of safety features including autonomous emergency braking, pedestrian detection, lane departure alert with steering assist, Lane Tracing Assist, Proactive Driving Assist, adaptive cruise control, and traffic sign recognition. An optional parking assist feature is also available, and traffic jam assist can be activated through a subscription service.

The luxury automaker has recently announced plans to introduce three vehicles to "three new segments" in the Australian market around mid-2024. The LM people mover has been confirmed as one of these vehicles, while the other two are predicted to be the Toyota Yaris Cross-inspired LBX small crossover and the brand new GX off-roader. With such diverse offerings in the pipeline, it's clear that Lexus is committed to fulfilling the varied needs and desires of its discerning clientele.
