Mercedes-AMG G63 2018 revealed

The new generation G-Class will be headlined with the next iteration of Mercedes-AMG's G63.

Benefiting from the weight reduction, increased fording depth and extra ground clearance of the 2018 G-Wagon, the G63 is set to be the meanest off-roader the company has ever offered.

The G63 uses the same 4.0-litre V8 twin-turbo engine found in the G 500, but in this guise the V8 has been tuned to deliver 430kW/850Nm, up from 310kW/610Nm.

Combined with a nine-speed automatic transmission and rear biased all-wheel drive system, the G63 can rocket from 0-100km/h in 4.5 seconds.

The SUV comes with cylinder deactivation that Mercedes claims help achieve a combined fuel consumption of 13.2L/100km while the combined CO2 emissions is 299g/km.

Underneath AMG has redesigned the independent double-wishbone front suspension and the rigid rear axle.

The front suspension is now mounted to the ladder-type frame to help drivability on and off the road.

AMG’s ride control suspension with adaptive adjustable damping is also present - the system automatically changes the damping for each wheel depending on the road surface and suspension setting.

As expected, the upcoming G63 will get a host of visual upgrades to set it apart from the standard models, including AMG badges, red brake calipers, flared wheel arches, side exhaust pipes and 22-inch wheels.

The optional AMG Night package adds dark tinted headlights, tail-lights and windows with complimenting Obsidian Black paint finish on the exterior mirror housings while the 21 or 22-inch rims are finished off in matte black.

There will also be a launch edition G63 called the “Edition 1” which will be available in Magnetite Black, Obsidian Black, Iridium Silver, Mojave Silver, Selenite Grey, Designo Graphite metallic, Designo Platinum Black, Designo Mystic White Bright, Designo Platinum Magno and Designo Night Black Magno.

Inside, there are two 12.3-inch display screens that combine into one to create a widescreen cockpit that has also been seen in the new A-Class, E-Class and S-Class.

The Mercedes-AMG G63 will premiere at this year's Geneva Motor Show with the new-generation G-Class set for an Australian launch in the third quarter of 2018. Local specifications and pricing will be announced closer to the local launch date.

Do you think the new G63 will be just as good off-road as the previous model? Let us know in the comments.
