The 2027 Mercedes-AMG GT 4-Door arrives at the end of the year with up to 1,153 hp and on a new architecture that can handle as much as 1,300 hp.It sports three new axial flux electric motors, two in the back and one in the front, that are 67 percent smaller and 67 percent lighter than previous Mercedes electric motors, with three times the power density and two times the torque density.The first models hit showrooms by the end of the year. No pricing yet.The automotive landscape is littered with failed experiments in two-door hyper-performance EVs: Rimac, Pininfarina, and the still-to-come Tesla Roadster, which we’ll believe when we actually see it, while supercar electrics like the Lotus Evija and YangWang U9 Extreme are being produced in such limited numbers that they might as well be irrelevant.Into that landscape comes a new silent-but-powerful Mercedes-AMG GT 4-Door. Mercedes swears it’s different. Different? Yes, it’s “practical.” You can justify a four-door sedan, even if it’s called a coupe for styling reasons, a lot easier than you can a two-door actual coupe.“One part of the magic is the everyday usability,” said no less an expert on the subject than Mercedes CEO Ola Källenius. “I’ve quickly offered to be a beta tester. My wife will approve. Why? Because we’re going to Sweden in the summer and the trunk of this car is huge. You can put probably three suitcases in there, a golfer can put a couple golf bags, you can go skiing with four people in that car. In terms of packaging and usability, it is a marvel. It is more than that. It is a car you can really use.”George Russell said last night at the car’s reveal in LA that it was the fastest car he’s ever driven. Granted, both Russell and Källenius work for Mercedes, so you’d more or less expect them to like it—in fact, they’re paid to like it—but they might have a point.Baby got backSure, a Mercedes GLS would be a good car for a trip to Sweden, too, but the difference is the AMG GT 4-Door you see here would also be a good car for dive-bombing the autobahn or even carving up a good mountain road. Look at the spec sheet:The AMG GT55 model of the 4-Door Coupe achieves a combined maximum of 805 hp and 1,328 lb-ft of torque, and the GT63 hits 1,153 hp and and 1,475 lb-ft, but the High Performance Electric Architecture on which it sits is designed for as much as 1,300 hp. For comparison’s sake, the Tesla Model S Plaid, an obvious competitor, makes 1,020 hp and the Porsche Taycan, the other obvious competitor, maxes out at 1,019 hp.The AMG GT 4-Door sports three brand new axial flux electric motors, two in the back and one in the front, with the front motor switched on only when you really want to get somewhere. The motors are 67 percent smaller and 67 percent lighter than previous Mercedes electric motors, with three times the power density and two times the torque density, Benz says. Are they a big deal? Here’s how Mercedes explains them: “In an axial flux motor, the electromagnetic flux runs parallel to the motor’s axis of rotation. In a conventional electric motor, it runs perpendicular to the axis. Key components of the axial flux motor are designed as thin discs: two rotors enclose the stator like a sandwich on the left and right. This arrangement allows optimal coupling of the magnetic flux generated by the stator to the rotors. In the new Mercedes-AMG GT 4-Door Coupe, this combination at the front axle is approximately 3.5 inches wide; each of the two motors at the rear axle are approximately 3.2 inches wide.”Luggage space The car’s 106-kWh battery is newly developed by AMG and YASA, a German firm Benz has owned since 2021. It consists of cylindrical cells measuring 26 mm in diameter and 105 mm vertically—a new configuration Benz says is best. These are oil-cooled for maximum performance. “We take out 25 kw of heat in the whole system,” said an engineer. “Others take out 5 kw.”Assuming you can find a suitable charger, maybe in a lab in Stuttgart or someplace, you can recharge that battery at 600 kW, which has to be some kind of record. That’ll give you 286 miles of range in 10 minutes, or go from a 10-percent state of charge to 80 percent in 11 minutes. Maximum range is listed at 475 miles on the European WLTP scale, which might be 400 miles on our scale here, we’ll see.You can adjust all that power to suit your driving needs at any given moment. While regular old Mercedes have the Comfort, Sport, and Sport+ settings, the AMG GT 4-Door has “Race Engineer Control” buttons, three rotary knobs on the center armrest. These manage the response control for the pedals and the drivetrain. If you thought that AMGs are too jumpy at the controls, you can smooth that out, for instance. With “Agility Control,” Mercedes says you can actually simulate a longer wheelbase that gives a more stable-feeling ride, or a shorter wheelbase for more agility. You can control traction to get nine different stages of slip, even doing burnouts, as we saw at the car’s reveal.“I promise you, you can have very much fun on the track,” said Källenius.2027 Mercedes-AMG GT 4-Door The body of the car doesn’t just sit there looking AMG-like, either. Active aero components, what Mercedes calls “aerokinetics,” adjust air flow and downforce throughout your drive. There’s a front active air panel that adjusts cooling air as needed, a venturi flow controlled by two active underbody elements that can create a venturi effect for improved downforce, and a rear active spoiler. AMG says it’s the world’s first active rear diffuser, first seen on the experimental ATXX and GTXX cars.“This car is really like a transformer.”And for those who miss the rumble of a big V8 internal combustion engine, with the push of a button you can artificially recreate the rumble of a big V8 internal combustion engine.Inside, the Mercedes AMG GT 4-Door is split into two clear zones, said Hannes Fiechtner, senior designer at Mercedes-Benz Advanced Design Studio in Carlsbad, California. “One for the driver, which draws inspiration from motorsport, while the passenger gets their own screen recessed behind the driver control center.”Large, round air vents on the outside of the dashboard are “crafted into the finest details to show the motorsports angle of the Mercedes GT,” Fiechtner said.Rear passengers have space to sit upright “with a lot of legroom.” There’s a panoramic glass roof. There are even racing stripes inside.Rotary controls for driving modes.“The exterior design is an evolution of essential purity,” said designer Fiechtner. “The roof is four centimeters (an inch and a half) lower than the current predecessor (AMG GT 4-Door Coupe), and that was already a very low car. It is a sheer, full, and super-clean body side. Strong front fenders contrast with the extremely low front hood. The concave front can be clearly recognized as an AMG. The rear optional ‘light boomerang’ integrates into the active aero spoiler. There is a big and especially wide rear black panel. This car is truly special, it’s designed to put a smile onto your face.”No prices were mentioned except to say the new car should cover the same price as the current AMG GT 4-Door. The current model starts with a GT43 powered by a 3.0-liter inline-six turbo engine with hybrid assist for $103,450. But there’s no GT43 in the new lineup. The current GT53 starts at $114,350, and the GT63 at $166,200.Autoweek SOC EV Newsletter sign upPrices for a Porsche Taycan, another four-door electric hyperbeast, range from $108,050 to $245,950. The Tesla Model S Plaid, another tri-motor electric sedan with amazing performance, start at $126,630. And both those are selling well enough, unlike the two-door hypercar EVs on the market. So maybe Ole is right.“We have the superior product,” he said. “We are so close to a conventional combustion car. There is no other customer car you can go to before going to our car. It is the performance of the car, the charging speed, the driver-centric seating position, it is just the combination of everything.”The AMG GT 4-Door will arrive in the US toward the end of this year for the GT55 model, and in early 2027 for the GT63. After that, other AMGs will follow on the same architecture, including an SUV and what Mercedes unfortunately termed an SUC, or Sport Utility Coupe, which it will hopefully rename. But the technology looks promising, and as the EV market rebounds from its little whoop-dee-doo when the $7,500 Federal tax credit was taken away, the market for something like this, largely insulated from the tax credit, could be strong.
