Great Wall Motor’s luxury Wey brand – which will debut in Australia later this year as a sub-brand – has just revealed a new flagship SUV that will be the first model based on its new GWM One S platform.

The Wey V9X is a six-seat, full-size SUV, measuring no less than 5299mm long, 2025mm wide and 1825mm tall on a 3150mm wheelbase. That makes it over 200mm longer than the GWM Tank 500, itself sized similarly to a Toyota LandCruiser 300 Series, on a 300mm longer wheelbase.

A slightly shorter version, on a 3050mm wheelbase with a total length of 5205mm, is also available. Interestingly, this is the one aimed at families, while the longer V9X is aimed at executives.

The V9X is yet to be confirmed for Australia, though GWM says it’s “under consideration”.

It debuts the new GWM One S architecture, a new “super platform” that’ll underpin everything from sedans and SUVs to utes and sports cars, and support a range of powertrain types including petrol, plug-in hybrid, diesel hybrid, electric and hydrogen fuel-cell.

All V9Xs employ a Super Hi4 plug-in hybrid (PHEV) system with a turbocharged 2.0-litre four-cylinder petrol engine with 175kW of power and 385Nm of torque, plus an electric motor on each axle, all-wheel drive and a four-speed dedicated hybrid transmission.

GWM also had examples on display at the Beijing motor show with number plates reading ‘EV’ and ‘HEV’, though no details are available yet on other powertrains.

There are three different configurations, all of which feature dual-chamber air suspension with continuously variable damping and rear-wheel steering, and which ride on 21-inch alloy wheels.

The Luxury Family Edition uses a 66.6kWh ternary lithium battery with 312km of electric range on the WLTC cycle. A 110kW/170Nm front electric motor and 220kW/380Nm rear motor mate with the four-cylinder engine to produce total system outputs of 500kW and 930Nm.

While the other variants use an 800V electrical system, the Luxury Extended Version is the only one to feature a 400V system and it features the smallest battery capacity of the lot at 55.4kWh. Electric range drops down to 240km.

It uses 100kW/170Nm and 240kW/312Nm electric motors for total outputs of 510kW and 862Nm.
