2026 MERCEDES-AMG G 63 4.0L V8 BITURBO — GCC SPECIFICATION

This entry describes grade-standard specification for the current W465-generation Mercedes-AMG G 63 as offered in the GCC. The originating dealer advertisement is no longer online, so no unit-specific build sheet could be verified; the equipment below is model-grade content rather than a confirmed option list for this individual vehicle. Each figure is labelled with the market it applies to.

ENGINE AND DRIVETRAIN

The AMG 4.0-litre V8 biturbo displaces 3,982 cc, with eight cylinders in a V configuration, four valves per cylinder, petrol direct injection and a compression ratio of 8.60:1. Both twin-scroll turbochargers sit inside the cylinder V rather than outboard of it. Rated output is 430 kW at 6,000 rpm, with 850 Nm available from 2,500 to 3,500 rpm. A note on units matters here: Mercedes-Benz publishes this as "430 kW (585 hp)", where "hp" is metric horsepower, so 585 PS equals 430 kW equals 577 bhp. Quoting 585 bhp overstates the engine by roughly eight brake horsepower.

The current car carries a 48-volt integrated starter-generator that adds a further 15 kW (20 PS) and 200 Nm for short intervals. This is mild-hybrid assistance only: there is no traction battery, no charge port, and the vehicle cannot be driven on electric power alone. Drive passes through an AMG SPEEDSHIFT TCT 9G nine-speed torque-converter automatic to AMG Performance 4MATIC permanent all-wheel drive with a 40 percent front to 60 percent rear torque split, three mechanical differential locks each with 100 percent locking effect, and a two-speed transfer case offering a 2.93:1 LOW RANGE ratio. Mercedes-Benz quotes 0 to 100 km/h in 4.4 seconds and a top speed of 220 km/h, rising to 240 km/h with the AMG Driver's Package per the GCC brochure. The engine is homologated to Euro 6e in Europe.

European WLTP figures are 15.7 to 14.7 l/100 km combined and 358 to 335 g/km CO2, CO2 class G. These are European values. The GCC publishes no homologation fuel-consumption or CO2 figure for this model, and the European CO2 number is deliberately not recorded against this vehicle. The engine's internal designation is not stated in any Mercedes-Benz document consulted and is therefore omitted rather than asserted.

CHASSIS, STEERING AND BRAKES

Suspension is double-wishbone independent at the front and a rigid axle at the rear. AMG RIDE CONTROL adaptive adjustable damping is fitted with Comfort, Sport and Sport+ settings, and AMG ACTIVE RIDE CONTROL provides active hydraulic roll stabilisation in place of conventional mechanical anti-roll bars. Steering is electro-mechanical rack-and-pinion; Mercedes-Benz does not publish a steering ratio for this model. Braking is by an AMG high-performance system with perforated discs and red-painted callipers, which become black when the carbon-fibre package is specified. Disc diameters are not published for the AMG grade — the 354 mm front and 345 mm rear figures in wide circulation belong to the non-AMG G-Class and are not carried here. The homologated standard wheel and tyre fitment is 9.5J x 20 ET35 on 275/50 R20; 22-inch AMG multi-spoke forged wheels are a GCC option. Turning circle is 13.43 m.

DIMENSIONS AND CAPACITIES

Overall length is 4,873 mm including the spare-wheel carrier on the rear door, and 4,634 mm for the body alone without it. Width is 1,984 mm excluding exterior mirrors and 2,187 mm with the mirrors extended. Height is 1,971 mm without a roof rack and 2,039 mm with one. The wheelbase measures 2,890 mm, with 1,650 mm front track and 1,654 mm rear track. Kerb weight is 2,640 kg measured to the EC method, which includes a 90 percent full fuel tank and a 75 kg driver. Payload is 560 kg and permissible gross vehicle weight is 3,200 kg. The fuel tank holds 100 litres including a 12-litre reserve. Luggage volume is 640 litres measured behind the rear seat bench; Mercedes-Benz does not publish a seats-folded maximum. Seating is the five-seat G-Class configuration.

One correction is worth recording, because the wrong figures are widespread. The commonly cited 4,825 mm length and 1,931 mm width belong to the non-AMG G 450 d, not to the G 63, and the 2,042 mm height quoted alongside them is measured with a roof rack fitted. The GCC brochure's scale drawing shows 4,863 mm and 248 mm ground clearance, but that drawing is a single generic W465 illustration serving several models with no per-model disambiguation, so the AMG-specific figures above are used instead.

EXTERIOR

The car carries the AMG-specific radiator grille with vertical louvres, the AMG crest on the bonnet, flared wheel arches, the rear-door mounted spare-wheel carrier and exterior surround lighting that projects the brand logo onto the ground alongside the vehicle. The recorded exterior finish is Monza Grey; the exact manufacturer marketing name should be confirmed against the build record before it is quoted.

The "Double Night Package" in this car's designation is the combination of the Night Package and Night Package II. Mercedes-Benz documents the Night Package as a radiator grille in dark chrome, darkened light units, obsidian black metallic mirror housings and grille surround, heat-insulating dark-tinted glass and darkened indicator and reversing lamps. Mercedes-Benz publishes no component list for Night Package II, so none is stated here. Both are appearance and finish packages — paint, chrome treatment, glass tint and lamp tinting. Neither adds engine, exhaust, suspension, brake or drivetrain content, and neither changes any figure in the technical data above. "Double Night Package" itself is market and dealer usage rather than an official Mercedes-Benz designation.

Several notable exterior options are not evidenced for this vehicle and should not be assumed fitted: the AMG Exterior Carbon-Fibre Package, MANUFAKTUR running boards in black with the black AMG exhaust system, and the 22-inch forged wheels. All three are flagged as optional on Mercedes-Benz GCC material.

INTERIOR AND SEATING

The grade-standard interior comprises the AMG-specific seat design in perforated nappa leather with the AMG pattern, an AMG Performance steering wheel, AMG door sill panels and AMG-specific instrument styling, in the five-seat layout with a folding rear bench. Interior trim colour is not recorded for this vehicle because the source advertisement is no longer available.

Equipment that is not evidenced and is therefore not claimed: AMG Performance seats, for which Mercedes-Benz publishes no confirmation of availability on the W465 G 63 at all; the MANUFAKTUR Package and SUPERIOR Line interior with active multicontour seats and ENERGIZING Package Plus; and interior carbon-fibre trim elements. The MICROCUT microfibre steering-wheel grip is a GCC option and is likewise unconfirmed.

INFOTAINMENT AND CONNECTIVITY

MBUX is fitted with AMG-specific display designs and AMG menu content across the twin digital displays, with touchscreen control of the central display. Burmester 3D surround sound is described as standard equipment for the G 63 in Mercedes-Benz UK press material and appears without an optional marker on the GCC AMG pages, but Mercedes-Benz's own GCC material gives two different speaker counts for the same-named system, and the fitment cannot be confirmed for this vehicle, so it is not claimed. MBUX High-End Rear Seat Entertainment with 11.6-inch screens is a GCC option and is not evidenced here.

DRIVER ASSISTANCE AND SAFETY

Assistance content on GCC-specification cars is configuration-dependent and must be confirmed against the individual build record. This distinction is material rather than cautionary boilerplate. On Mercedes-Benz's GCC W465 pages, Active Brake Assist, Active Lane Keeping Assist and Trailer Manoeuvring Assist each carry the "optionally selectable equipment depending on configuration" flag, whereas the equivalent systems are standard in UK and European specification. Systems that are standard in Europe — PRE-SAFE, DISTRONIC adaptive cruise control, Blind Spot Assist, Active Parking Assist with PARKTRONIC and the 360-degree camera parking package — are not documented on the GCC pages and are not claimed for this vehicle.

Systems documented on the GCC pages, with availability dependent on configuration, are Active Brake Assist including pedestrian, cyclist and cross-traffic functions, Traffic Sign Assist, Active Lane Keeping Assist, Trailer Manoeuvring Assist, adaptive headlamps and the off-road transparent-bonnet virtual view. No assistance system is asserted as fitted to this individual vehicle. Structural and passive safety content is the G-Class standard provision: anti-lock braking, the Electronic Stability Programme with off-road modes, traction control, front, front-side and window curtain airbags, ISOFIX child-seat anchorages, tyre-pressure monitoring and belt tensioners.

OFF-ROAD AND TOWING

The G 63 retains the full G-Class mechanical off-road package: three differential locks each with 100 percent locking effect, and a two-speed transfer case whose 2.93:1 LOW RANGE is engaged in neutral at up to 40 km/h, with the return to HIGH RANGE possible up to 70 km/h. Mercedes-Benz's GCC AMG owner's supplement gives AMG-specific geometry of 245 mm minimum ground clearance, a 27.2-degree approach angle, a 29.9-degree departure angle without a trailer hitch or 24.8 degrees with one, 700 mm fording depth and 100 percent gradeability, equal to a 45-degree incline, in LOW RANGE. The generic G-Class figures of 31 and 30 degrees should not be read across to this model: the AMG bumpers and the larger wheel and tyre package reduce both. Breakover and tilt angles are not published on an AMG-specific basis and are omitted.

Towing capacity is 3,500 kg braked and 750 kg unbraked, with a maximum nose weight of 140 kg and a permissible rear axle load of 1,900 kg in trailer operation. Maximum roof load is 150 kg, and roof loading is not permitted at all on cars fitted with the AMG Performance Package.
