2024 Toyota Grand Highlander revealed, unconfirmed for Australia

The 2024 Toyota Grand Highlander – a longer, wider and taller version of the Kluger – has debuted at the Chicago Auto Show.

As a relative to the Kluger – sold elsewhere as the Highlander – the roomier vehicle features a unique, boxier design similar to the smaller RAV4, "adult-sized" third-row seating, and an available 2.4-litre turbo-petrol hybrid system borrowed from the Toyota Crown and Lexus RX.

While it hasn't been ruled out entirely for Australia, a spokesperson for Toyota's local arm said it has no news to share about the Grand Highlander at present, with right-hand-drive production looking unlikely.

"Toyota is always considering exciting new models as they become available for our market, but we have no announcements to make today."

It will be built alongside the Kluger in Indiana, USA – however, the tweaked interior is likely to see a right-hand-drive variant ruled out.

In addition, the LandCruiser 300 Series is available for customers looking for a roomier three-row SUV option, but it is considerably more expensive.

According to US media, the Grand Highlander has a 2946-millimetre wheelbase, and measures 5116mm long, 1989mm wide and 1806mm tall – making it 165mm longer, 58mm wider and 50mm taller than a Kluger, with an additional 102mm between the axles.

This is larger in every dimension than a LandCruiser 300 Series (except height), and other large SUVs such as the Mazda CX-9, Hyundai Palisade and Nissan Pathfinder.

It is also roughly the same length as the popular Kia Carnival people-mover.

With a larger footprint, the Grand Highlander has improved second-row legroom (up 140mm), while it has 25mm more headroom and around 50 millimetres of additional shoulder space.

As standard, eight-passenger seating is offered, with available second-row captain's chairs on the flagship Platinum grade.

Like the Mazda CX-8 and CX-9 LE, the captain's chairs are heated and ventilated – but, as with the Hyundai Palisade and Nissan Pathfinder, it eschews a fixed centre console for a walk-through to the third row.

Toyota claims it offers 595 litres of space behind the third-row – 142L more than a Kluger – or 2775L with the rear-most seats folded, measured to the roof.

Under the skin, the Grand Highlander is underpinned by the same TNGA-K architecture as the Kluger, but with additional rigidity to reduce noise, vibration and harshness levels.

In addition, Toyota says it has redesigned the rear suspension for a more comfortable ride, and to maximise space in the third-row and boot area.

As with the Kluger, the Grand Highlander will be offered with a 2.4-litre four-cylinder turbo-petrol – which replaces the long-running 3.5-litre naturally-aspirated V6 for 2023 – or a 2.5-litre naturally-aspirated petrol-electric hybrid.

The updated Toyota Kluger will arrive in Australia later this month with the 2.4-litre turbo-petrol and additional technology, including a 12.3-inch infotainment system.

However, the Grand Highlander is headlined by the addition of the brand's 'Hybrid Max' powertrain that combines the internal-combustion 2.4-litre turbo with two electric motors, for a total system output of 270kW and 542Nm.

It is matched to a six-speed automatic transmission and offers all-wheel drive, while the turbo-petrol and regular hybrid are front-wheel drive with optional AWD.

While the powertrain is identical to that used in the not-for-Australia Toyota Crown and slightly less powerful than the Lexus RX500h, it has been retuned to allow for a 5000-pound towing capacity (2268 kilograms).

It offers a 0-60mph (0-97km/h) sprint time of 6.3 seconds.

Inside, the Grand Highlander includes a standard 12.3-inch infotainment system, an available 12.3-inch digital instrument cluster, an 11-speaker JBL audio system, seven USB-C ports, and 13 cupholders.

The 2024 Toyota Grand Highlander will commence production in the United States later this year.
