The 2018 Mercedes Benz E63 AMG in a fine metallic black coat is not a vehicle that requires an introduction, but it makes one anyway, and it does so with a force and a finality that leaves everything in its immediate vicinity feeling considerably less significant than it did a moment before. The metallic black finish moves across the E63's wide, lowered, and thoroughly AMG-transformed body with a depth and a darkness that is as theatrical as it is deliberate, the coat catching light along every sculpted surface and every aggressive body line of this performance sedan's extraordinary exterior with a brilliance that makes the vehicle look simultaneously composed and coiled, like something holding an immense amount of power in careful and deliberate reserve. The AMG-specific exterior modifications are immediately and unmistakably present, from the wider front fascia with its prominent air intakes that hint at the cooling requirements of what lies beneath, to the quad exhaust tips at the rear that sit wide and purposeful and make absolutely no attempt to conceal the intent of the vehicle they belong to. In metallic black, every one of these AMG details is presented with a sharpness and a menace that is deeply compelling, the dark coat unifying the exterior into a single, cohesive statement of performance intent that is as refined in its execution as it is serious in its purpose. This is a vehicle that wears fine print on the outside, and every letter of it is written in metallic black.

Step inside and you are indeed stepping into fine print of the most exquisite and most lavishly conceived kind. The AMG bucket leather seats greet the driver and passenger with a sculpted, embracing form that is both the visual centrepiece of the interior and its most immediately felt physical impression, their lateral bolstering wrapping occupants with a firmness and a precision that communicates the performance character of this sedan before a single revolution of the engine has occurred. The seats are equipped with both heating and cooling, and the memory function ensures that every driver's perfect position is stored and recalled with instantaneous accuracy, making the relationship between occupant and cabin feel personal, prepared, and completely resolved from the moment you settle in. The heated steering wheel places the driver at the heart of a cockpit that has been assembled with AMG's characteristic blend of performance focus and premium luxury, every material and every surface within this interior chosen and finished to the standard that a vehicle of the E63's standing demands without negotiation. The 21.3-inch information screen commands the dashboard with a sweeping digital authority that brings every piece of technology and every system this AMG contains into a single, beautifully rendered interface of extraordinary clarity and sophistication, while the Burmester surround sound system fills the cabin with an audio performance so rich, so precisely layered, and so completely immersive that it transforms the interior of the E63 into a concert hall that happens to travel at velocities most vehicles would find deeply uncomfortable.

And then there is the engine, and with it, every other conversation in this review becomes a supporting act. The 4.0-litre twin-turbocharged V8 M177 unit that resides beneath the E63's bonnet produces 603 horsepower at up to 6,500 rpm and 627 lb-feet of torque available from as low as 2,500 rpm, figures that are not merely impressive but genuinely and completely staggering in the context of a full-size executive sedan. The twin turbos ensure that the delivery of that torque is immediate, seamless, and utterly relentless, arriving with a wave of force so broad and so abundant that the nine-speed automatic transmission has the full measure of its work cut out managing the power flowing through it to all four wheels via AMG's 4MATIC all-wheel drive system. The result of this extraordinary mechanical partnership is a zero to sixty time of 3.4 seconds, a number that belongs in the company of dedicated sports cars rather than executive saloons, and yet the E63 achieves it while remaining composed, controlled, and impeccably refined in the way it delivers that performance, the Burmester-filled cabin insulating its occupants from the fury occurring beneath them with a completeness that makes the speed feel almost surreal in its effortlessness.

The 2018 Mercedes Benz E63 AMG in metallic black is a vehicle that exists at a level of completeness so rare and so thoroughly achieved that it renders most comparisons irrelevant before they can even begin. It is a 603-horsepower executive sedan dressed in fine metallic black, lined in AMG leather, filled with Burmester sound, and capable of embarrassing sports cars at a traffic light without disturbing a single hair of the occupant comfort within its cabin. It is fine print in the most literal and most spectacular sense, the kind that rewards those who take the time to read every word of it, and punishes those who underestimate it with a swiftness and a completeness that 3.4 seconds does not leave much room to question.
