Few vehicles blur the line between luxury SUV and outright performance machine quite like the G-Class, and it is this contradiction that keeps the Mercedes-Benz G63 V8 supercars conversation alive across Dubai's car scene. It is not a supercar in the traditional sense, but its twin-turbo V8 heart, aggressive stance and genuine straight-line pace mean it routinely gets mentioned in the same breath as machines with far lower ground clearance and far fewer seats.
At Dourado Luxury Cars in Dubai, this reputation is on full display. The G-Class has long been a cornerstone of our Mercedes collection, and it remains one of the most requested silhouettes among buyers who want serious performance without sacrificing the practicality of an SUV. Few vehicles anywhere manage that combination as convincingly. Our featured example is a 2021 Mercedes-Benz G63 AMG finished in black, fitted with the G7X Onyx Kit, and powered by the same 577 hp V8 that has defined this generation of G-Wagon. Buyers who want to see how the G63 platform can be pushed further should also look at our Mercedes Benz G800 G-Class Brabus, a 2021 model that takes the same underlying architecture and turns the performance dial up considerably.
The Case for the G63 Among Supercars
The comparison between a boxy, seven-seat SUV and a low-slung supercar might seem unlikely on paper, but the numbers tell a different story. The G63's handcrafted 4.0-litre biturbo V8 produces 577 hp, enough to send a vehicle weighing well over two tonnes toward triple-digit speeds with a directness that few SUVs can match. It is this raw output, paired with permanent all-wheel drive and a nine-speed automatic transmission, that has earned the G-Class its reputation as one of the few SUVs genuinely capable of holding its own against sports cars off the line. It helps that Mercedes-AMG has never treated the G63 as a compromise. The engineering philosophy has always been to build the most extreme version of the G-Class possible while retaining the model's unmistakable silhouette, a formula that has proven remarkably durable across generations.

Inside Dourado's Featured G63 AMG G7X Onyx Kit
The example currently in our Al Quoz showroom is a 2021 Mercedes-Benz G63 AMG finished in black and fitted with the G7X Onyx Kit, a body enhancement package that sharpens the G-Class's already imposing road presence. The kit adds a more aggressive front fascia, revised bumpers, and widened arches that give the vehicle a broader, more purposeful stance without altering the fundamental proportions that make the G-Class instantly recognisable. Beneath the bodywork sits the same 577 hp twin-turbo V8 found across the standard G63 range, meaning performance credentials are matched by visual drama. For buyers in Dubai who want a G-Class that stands apart from the ones already common on Sheikh Zayed Road, this combination of factory-grade power and bespoke styling represents a compelling middle ground between stock and fully customised builds.
The Onyx Concept Touch: Bespoke Design Language
Onyx Concept has built a strong reputation in the region for reworking the G-Class into something more distinctive, and the G7X Onyx Kit fitted to our featured car is a good example of that philosophy in action. Rather than reinventing the vehicle, the design language focuses on sharpening existing lines, adding visual weight to the wheel arches, and giving the front end a more chiselled, road-hugging appearance. Readers interested in the brand's design ethos can find more detail at Onyx Concept.
Dourado currently stocks several other Onyx Concept G-Class builds, each demonstrating a different interpretation of the formula. These include the G7X by Onyx Concept in Mystic Brown Metallic from 2022, and the striking G8X Oscar by Onyx Concept, a 1-of-5 limited-edition finished in Nardo Grey. For buyers seeking true exclusivity, the one-off G9X Onyx Concept Mirage Edition represents the far end of the customisation spectrum.
Performance Numbers That Rival the Supercar World
It is worth being precise about what puts the G63 in supercar conversations and what does not. This is, unambiguously, a luxury SUV, not a two-seat supercar, and it should never be mistaken for one. What it does share with that world is a genuine performance ceiling that few other SUVs can approach. A 577 hp V8, all-wheel drive, and a nine-speed automatic gearbox give the G63 a straight-line character that punches well above its segment, even if its dynamics on a twisting road remain those of a tall, boxy vehicle rather than a mid-engined coupe. This is precisely why the G63 has found such a loyal following in Dubai. It offers buyers the drama, sound, and acceleration associated with performance cars, without asking them to give up rear seats, ground clearance, or everyday usability. For a market where both practicality and presence matter, that balance is difficult to beat.
Other G-Class Options in Dourado's Showroom
Buyers exploring the G63 platform have several routes to choose from within our current stock. Alongside the featured 2021 G7X Onyx Kit model, Dourado also holds a 2023 Mercedes-Benz G63 AMG and a newer 2025 Mercedes-Benz G63 AMG, giving buyers the option of a more recent model year alongside the character of the earlier, Onyx-enhanced example.
For those who want to push beyond even the G63's numbers, the Brabus-tuned G800 G-Class demonstrates how far the same base platform can be developed by an established German tuning house. Each of these vehicles forms part of the same broader story: a G-Class platform robust enough to be reinterpreted in several distinct directions while never losing its fundamental identity.
Why Dubai's Enthusiasts Choose the G63
Dubai's relationship with the G-Class runs deep, and it is not difficult to understand why. The city's roads reward vehicles that combine presence with performance, and few silhouettes command attention the way a G63 does, particularly one finished in black with a widened Onyx Kit body. Add a genuinely potent V8 into the mix, and it becomes clear why this model continues to hold its place among the most desirable SUVs in the region, supercar comparisons included.
