The star of the updated range is the G500 model, which is now powered by the same 4.0-litre direct-injection twin-turbo V8 engine used in the Mercedes-AMG GT coupe and the C63.

In the G-Class this engine has been tuned to deliver 310kW of power and 610Nm of torque. The old G500 model had a 5.5-litre V8 with 285kW of power. According to Mercedes-Benz, the new motor is able to propel the G500 from 0-100km/h in 5.9 seconds.

The engines fitted to the rest of the range have also been tweaked. The 3.0-litre turbo-diesel in the G350d now produces 180kW/600Nm, up from the 155kW/540Nm available in the outgoing model.

More power is also available in the G63 AMG, as its turbocharged 5.5-litre V8 now churns out 420kW/760Nm, an improvement of 20kW. Meanwhile, the 6.0-litre V12 in the G65 AMG has been tuned to deliver 13 extra kilowatts, with output now rated at 463kW/1000Nm.

Suspension settings have been tweaked across the range and include revised shock absorber settings. Changes have also been made to the tuning of the car's stability control and anti-lock brake systems. Automatic engine start/stop is now fitted to all G-Class models except the V12 G65.

Buyers of the new G500 model can specify it with an adaptive damping system that lets the driver choose from either sport or comfort modes.

Visually, all models in the updated G-Class range are equipped with the flared wheel arches that used to be only available on AMG models. Some variants also sport revised bumpers, while the instrument cluster on all models has been updated.

A host of new colours have been made available for the revised G-Class, including yellow (top), tomato red, lime green and orange.

Carryover items include the G-Class' permanent four-wheel drive system, three differential locks, low-range gearbox, and the now 36-year old body that sits atop a ladder frame.

Sales of the revised G-Class begin around the middle of the year in Europe.

Update: According to Mercedes-Benz Australia, the re-engined G500 and the other members of the updated G-Class range are currently under consideration for local sale, but nothing's been confirmed as yet.
