The GLS however isn’t entirely all new - based on the GL that came before it, the GLS receives a front-end make over with new headlights, bumper, grille and bonnet, as well as revised taillights and bumper at the rear.
The name is a result of melding the existing GL name, which will feature across the Mercedes-Benz SUV line-up, and appending the appropriate sedan designation - in this case, as the flagship model of the SUV range, the S name is applied.
Inside there’s seating for seven, with the requisite plush trim options, should you wish to climb even further upmarket - quilted Nappa leather, LED ambient lighting, and a range of two-tone trim colours making up just some of the available options.
The biggest change to the interior is a revised centre stack and redesigned console, as seen in the GLE range, launched earlier this year. A larger 8.0 inch display and simplified controls give the GLS interior a more up-to-date look.
Engines have been tweaked slightly to deliver increased performance, the range includes the GLS350 d, with a turbo diesel V6 delivering 190kW and 620Nm. The GLS400 offers a 245kW/480Nm twin turbo petrol V6.
A pair of V8 engines choices starts with the GLS500 rated at 335kW (15kW more than before) and 700Nm, while the all-conquering Mercedes-AMG GLS63 pumps out a scenery-blurring 430kW (an extra 20kW compared to its predecessor) and 760Nm.
All regular versions are mated to Mercedes’ own 9G-Tronic nine-speed automatic transmission and 4Matic all-wheel drive, while the GLS63 is backed by a seven-speed automatic.
Airmatic air suspension can be controlled via the centre-console mounted Dynamic Select controller, to tailor driving modes through Comfort, Slippery, Sport, Off-road and individual modes.
Those that wish to venture further off the beaten track can also option the Off-Road Engineering package, which adds a low range transfer case and locking centre diff, as well as a raised ride height allowing up to 306mm of ground clearance.
Safety systems include Collision Prevention Assist Plus, Crosswind Assist, Attention Assist, Pre-Safe collision preparation, plus cruise control and speed limiter.
Optional safety systems include radar-guided Distronic cruise control with ‘stop and go’ function, pedestrian detection, cross-traffic alert, blind spot assist, and active lane keeping.
Australian deliveries are expected to begin in the second quarter of 2016, with pricing and specification to be detailed closer to launch.
