Hot on the heels of the regular G-Class range, Mercedes-Benz has officially unveiled its new AMG G63 blending all of the new generation G’s interior and structural improvements with the performance arm’s ballistic twin-turbo 4.0-litre V8.
The new G63 makes the switch from a larger 5.5-litre twin-turbo V8 but gains an extra 10kW and 90Nm with 430kW and 850Nm available from the new 4.0-lire engine, allowing the 2018 G63 to dash from 0-100 km/h in 4.5 seconds.
Power is put to the ground via a nine-speed automatic and newly conceived AMG Performance 4Matic four-wheel drive system providing a more rear-ward biased delivery of power.
A public debut is set for Geneva Motor Show ahead of going on sale overseas June.
The new G63 aims to build on the largely unique qualities of its boxy predecessor with the adoption of a contemporary aluminium body shell and widened ladder frame chassis. They provide the new model with an added 210mm of width and what Mercedes-AMG describes as greater comfort and stability.
Setting the 2018-model-year G63 apart visually from the new G500 revealed at the Detroit Motor Show last month, are a number of typical AMG design cues including a unique grille with 12 vertical elements and a deeper front bumper featuring a matt silver kick plate.
Widened wheel arches, red-painted brake callipers, standard 21-inch wheels, AMG running boards and side-exit exhaust tips also help set the G63 apart from more sedate C-Class variants.
The rear end receives an AMG specific bumper with the same matt silver elements as that up front together with a stainless steel cover for the spare wheel.
Thanks to changes made to the basic G-Class’ packaging the interior of the new G63 offers greater accommodation, including an added 150mm of rear legroom compared with its predecessor.
Housed within a newly designed dashboard is Mercedes-Benz’ Widescreen Cockpit. It comes with standard analogue instruments but can be ordered with digital instruments in combination with a 12.3-inch infotainment display.
The new AMG model also receives redesigned front seats and a new rear bench that can be folded down to extend boot capacity.
Despite a kerb weight of 2485kg, Mercedes-AMG claims the new G63 accelerates to 100km/h some 0.9sec faster than its predecessor, with top speed capped at 220km/h or lifted to 240km/h with an optional driver’s package that brings upgraded wheels and tyres.
By comparison, the supercharged 4.0-litre V8 powered Range Rover Sport SVR, armed with 405kW and 680Nm, hits 100km/h from standstill in a claimed 4.7sec and reaches a top speed of 260km/h.
To go with its increased performance stats the new G63 also improves on its predecessors efficiency with a claimed combined cycle figure of 13.2 l/100km, brining a 0.6 l/100km improvement.
The new range-topping G-Class model is underpinned by a heavily reworked suspension that departs radically from that used by its predecessor. It uses a new double wishbone design at the front and a revised multi-link arrangement boasting rear spring travel of 82mm under compression and 142mm in rebound along with a ground clearance of 241mm for the rear axle.
Standard equipment includes AMG Ride Control featuring adaptive damping and three different damping modes: Comfort, Sport and Sport Plus.
The new G63 will be launched with a limited volume “Edition 1” model featuring a range of exclusive exterior colours, side stripes and black 22-inch forged aluminium wheels together with an updated interior with sport seats in black and red leather, carbon fibre trim element and a flat-bottomed AMG Performance steering wheel.
