Lexus has unveiled a five-seat version of its LX570 four-wheel drive for the Los Angeles motor show, but it won't be coming to Australia.

Under the skin, the five-seater is the same as the three-row car. That means power from a 5.7-litre V8 engine making 270kW and 550Nm of torque, hooked up to an eight-speed automatic gearbox.

But where the eight-seater has just 44.7 cubic-feet (1266L) of space behind the second row, the five-seater has a (seriously) handy 50.5 cubic-feet (1430L) to work with. Lexus says the extra room will appeal to smaller families, empty nesters or households with multiple cars, where holding a eight people is less common.

Instead of screaming kids and their bratty friends, the company expects owners to use the space for golf clubs, ski gear, bikes or – and we aren't making this one up – antique furniture. According to Lexus, owners occasionally have a penchant for antique collecting.

In case the extra boot-space isn't enough for all your bikes, skis or antiques, the car also comes with roof running rails as standard.

Just one trim level will be offered in the two-row LX 570, with essentially all the gear owners could want. That means a full-leather interior, four-zone climate control, a moonroof and a power tailgate. Parking assist, complete with a surround-view camera, and blind-spot monitoring are standard, along with rear cross-traffic alert.

Lane-departure warning, auto high-beam and adaptive cruise control are all standard as well – suiting drivers covering long distances on the highway to a tee.

A 12.3-inch infotainment screen sits atop the dashboard, as it does in the three-row car, and owners can use their mobile phone to remotely start, cool and lock their vehicles as part of the Lexus Enform Remote app – although the service is only free for 12 months.

In the USA, the car will be priced at US$84,980 ($112,042) – but don't expect to see it Down Under. Nick Raman, PR manager for Lexus Australia, said there weren't any plans to bring the car here at this stage.
