Mercedes-AMG chose Los Angeles for the world premiere of the second-generation GT 4-Door Coupe, and the choice carries symbolic weight. This is a car for a market that has embraced electric performance more enthusiastically than almost anywhere else in the world. It is also AMG's first bespoke electric vehicle: not a regular Mercedes with an AMG body kit, not a converted combustion car, but a ground-up EV developed by AMG's own engineers on the new AMG.EA platform.

The original GT 4-Door, launched over eight years ago, was powered by a 4.0-litre twin-turbo V8 producing 630 hp in its most powerful form. It was one of the best performance saloons of its era. The new model replaces every single component of that powertrain with electric motors: three of them, using axial-flux technology from Yasa, the company whose motors power the Mercedes-AMG Petronas Formula 1 team, and which Mercedes acquired in 2021. The result is a car that produces 1,153 hp and reaches 100 km/h in under two seconds.

The performance figures of the new AMG GT 4-Door are not aspirational estimates. They are the result of a three-motor setup using Yasa axial-flux motors: a technology that delivers dramatically more power per kilogram than conventional electric motors. The front axle carries one motor, the rear axle carries two, and the combined system produces 1,153 hp in peak mode with torque figures that make the original GT 4-Door's V8 seem almost polite by comparison.

The 800-volt electrical architecture supports DC fast-charging at up to 600 kW: a figure that, as one reviewer noted, makes the new AMG GT officially the fastest-charging non-Chinese EV on the market, and within striking distance of what the best Chinese manufacturers currently offer. At 600 kW, the 10 to 80% charge takes approximately 11 minutes. Even allowing for the fact that 600 kW chargers are rare, the 270 kW capability at more common fast chargers keeps real-world charging practical.

The most talked-about aspect of the new AMG GT 4-Door is not its power output, its charging speed, or its design. It is the sound. AMG's engineers spent years developing the AMGFORCE Sound system: a synthetic audio experience that specifically attempts to replicate the sound of the AMG GT R's V8, rather than creating a generic electric vehicle noise.

The system uses over 1,600 individual audio samples, combined in real time depending on throttle input, vehicle speed, load, and shifting events. The result changes dynamically in a way that static recorded sounds cannot: it has a different character at idle, at low load, at full acceleration, and on overrun. AMG has also programmed simulated gear changes, triggered by the steering wheel paddles, that create a physical sensation through the car's driveline and a corresponding rise and fall in the synthetic soundtrack. There are even custom sounds for unlocking the car, plugging in the charger, and activating launch control.

Every journalist who heard it in person at the LA premiere described it the same way: genuinely impressive, and more convincing than any synthetic car sound they had previously encountered. The critical question, which divides opinion sharply, is whether impressive is the same as right. You can turn it off entirely. AMG has made the system optional in every mode below AMGFORCE S+. The purists, at least, have an exit.

The fake V8 sound is the defining controversy of the new AMG GT 4-Door, and the reaction splits cleanly along two lines. Neither side is wrong. They are simply answering different questions.

What is undeniable is that AMG has made the most technically accomplished attempt yet at solving this problem. Whether you think it needed solving, or whether you think it is the wrong problem to be solving, depends entirely on what you believe a performance car is for.

The exterior of the new AMG GT 4-Door is polarising in the most AMG way imaginable: the front end is genuinely imposing, the rear is genuinely controversial. A new illuminated AMG grille with vertical slats and star-shaped LED daytime running lamps gives the front an aggressive, wide-set face that references AMG's racing heritage without quoting it directly. The bonnet carries large power domes inspired by AMG race cars. The illuminated Mercedes star sits at the centre of the nose, a design choice that reads as confident rather than garish in photographs.

The rear is where opinion divides. The taillights and boot lid design have attracted criticism from the automotive press for looking cluttered relative to the clean, muscular front. Carscoops called it outright the fugliest back end on any new car in recent memory. Other reviewers have been kinder, noting that the rear reads better in motion than in static images. The overall proportion of the car, at least from the front three-quarter angle that most press shots use, is commanding.

The new AMG GT 4-Door matters as a data point for the entire industry. This is the first time AMG has built a car around a purely electric powertrain from the ground up. Every other AMG EV has been a converted Mercedes or a hybrid. This one is different: a car whose architecture, platform, motors and software were all designed together specifically for AMG's performance mission. The results, in terms of power, charging speed and claimed range, are genuinely impressive by any standard.

But it also arrives at a moment when the automotive world is having a very public argument about whether electrification is compatible with driving passion. Porsche said yes to the GT3 S/C and its 9,000 rpm flat-six. GM said yes to the V8 with $691 million invested. BMW said yes to a V8 grand tourer with Vision Alpina. Audi said yes to a V8 PHEV RS6. Every one of those decisions happened this year. And now Mercedes-AMG says: we are going electric, but we will simulate what you are losing. The industry's answer to the EV transition is not one answer. It is every answer simultaneously.

Whether the fake sound is the right decision, whether the rear end deserves the criticism it is getting, whether 1,153 hp from three electric motors is more impressive than 630 hp from one V8: none of these questions have simple answers. What is simple is this. The new AMG GT 4-Door is the most powerful car AMG has ever made. It does not have a real V8. And it is one of the most important cars of 2026 regardless of how you feel about either of those facts.
