Mercedes-Benz has introduced the new GLS in Australia, in two different guises, the 450 4Matic and the 400 d 4Matic.

Pricing starts at AU$144,600 (US$98,951) for the petrol-powered version and AU$151,300 (US$103,536) for the diesel, with deliveries to commence next month. That’s around 30 percent more than the MSRP of the gasoline model in the States where it starts from US$75,200.

The new GLS 450 features a 3.0-liter inline-six with EQ Boost mild-hybrid technology, a nine-speed automatic transmission and all-wheel drive. It makes 362 HP (367 PS) and 500 Nm (369 lb-ft) of torque, with up to 16 kW (22 PS / 21 hp) and 250 Nm (184 lb-ft) of torque provided for short periods by the EQ Boost system. Fuel economy is rated at 9.2 l/100 km (25.6 mpg US).

Standard equipment includes an electric tailgate, power-closing doors, panoramic sunroof and 21-inch alloy wheels. The SUV also gets active cruise control, 360-degree camera system active parking assist, lane keeping and lane changing assist, blind spot assist and rear cross-traffic alert.

For AU$3,500 (US$2,395), it can be specified with the Off-Road Engineering package, with variable AWD, a low-range gearbox with variable torque distribution, downhill speed regulation, Off-Road driving mode and underbody protection. The Towbar Package will set you back AU$1,900 (US$1,300) and adds trailer stabilization and, obviously, a towbar.

Powering the GLS 400 d is the 3.0-liter, inline-six turbodiesel that puts out 326 HP (330 PS) and 700 Nm (516 lb-ft) of torque. This version of the brand’s range-topping SUV also comes with the nine-speed automatic transmission and all-wheel drive. It packs the same levels of equipment as its petrol-powered sibling and has an average fuel consumption of 7.7 l/100 km (30.5 mpg US).
