The second generation G-Class (W463) was launched on 14 January 2018 at the North American International Auto Show in Detroit.

In contrast to its predecessor, the new G-Class has grown 121 millimeters in width and 53 millimeters in length. The ground clearance has increased by 6 millimeters. The increase in width is for more driving stability, sturdier side impact protection, and more seating comfort. The increased length, especially in the front end, is due to the new 2019 EU pedestrian impact safety regulations: the previous generation did not have enough open space between the car’s front end and the rigid components beneath for the crumple zone as to mitigate the injury to a pedestrian’s body.

A major change was with the steering system which was switched from a recirculating ball system to variable-ratio rack-and-pinion with adaptive electric power assistance. The new steering system allows safety and convenience equipment such as active lane-keeping assist, Pre-Safe collision avoidance systems and self-parking capability. The rack-and-pinion steering system does not work with solid front suspension so a change was made to use independent front suspension.

The extensive, ground-up redesign allowed engineers to incorporate more lightweight materials such as high-strength and ultra-high-strength steels and aluminums. In addition, the redesign led to an improved manufacturing process which increased structural rigidity. The gap between the doors and body shell is much narrower than the previous generation. Despite the increased dimensions, the weight has been reduced by about 170 kilograms.

The second generation W463 is similar visually to the first generation, and the chassis code, W463, is still retained rather than W464 as some media outlets erroneously reported. However, only three parts from the previous generation were carried over to the new generation: the headlamp washers, the push-button door handles and the spare wheel cover bolted to the rear tailgate

Alongside the new G 500/G 550, Mercedes-AMG unveiled the new G 63 in March 2018 at the Geneva International Motor Show. The model is powered by the V8 twin-turbo M177 engine, producing 577 hp and 627 lb⋅ft of torque, an increase of 14 hp and 66 lb⋅ft over the previous generation G 63 AMG. Mercedes-AMG claims a 0-60 mph time of 4.4 seconds and a top speed of 149 mph with the optional Driver’s Package. The G 63 now defaults to a rear-biased 40:60 torque split versus the 50:50 split of its predecessor.

In addition to the performance increases over the G 500/G 550, the G 63 also features AMG-developed suspension, larger red brake calipers and perforated brake discs, AMG-specific transmission modes, radiator grille, flared wheel arches, striking side pipes on the exhaust system, and wider wheels up to 22-inches in diameter. The model features distinct front and rear fascias and body styling, as well as an AMG-specific interior with a standard AMG Performance steering wheel with flattened bottom.
