The upcoming 2027 Mercedes-AMG GT 63 4-door coupé is an electric ultra high-performance car. This is not a supercar, not a super sedan, but a hypercar with 1,153 electric horsepower. In the most aggressive of the available seven calibration settings, GT 63 can hit 60 mph in 2.0 seconds.Mercedes-Benz AGLet’s cut to the chase in the first paragraphs. The upcoming 2027 Mercedes-AMG GT 63 4-door coupé is an electric ultra high-performance car. This is not a supercar, not a super sedan, but a hypercar with 1,153 electric horsepower. “Relentless” will be an inescapable descriptor.In the most aggressive of the available seven calibration settings, GT 63 can hit 60 mph in 2.0 seconds. Yes, two seconds flat, thanks to three axial flux motors and battery technology that’s a near-direct transfer from AMG’s currently dominant Formula One team. The entire car is at what we used to call the bleeding edge.AMG GT 63’s body structure is completely new, a mix of aluminum, steel and fiber-reinforced composites that provide high rigidity with low weight. The sophistication of the body structure is definitely worth a few lines in the car’s elevator story.Battery-electric vehicles tend to be heavier than piston cars, so the estimated curb weight of 5423 lbs. is no surprise. It’s about 600 pounds heavier than the remarkable AMG C 63 S E hybrid sports sedan. Six hundred pounds is a small price to possess hypercar performance.Mercedes-Benz AGIn 6.4 seconds AMG GT 63 can reach 124 mph (200 kph), performance that will likely deliver a quarter-mile time in the nines. Numbers like that savagely rip at the time-space continuum in ways piston-engine cars simply cannot.Most importantly, in 6.4 seconds you’re approaching at the limit of what most Americans are willing to risk on open highway for a few moments of bliss. With AMG GT 63, every highway onramp holds the promise of a rocket sled ride.MORE FOR YOUI’ve driven cars capable of brushing into “the twos” and low 3-second range, and the experience is mind-altering, and demanding on the human body. In an electric hypercar, such performance is easily accessible and utterly smooth, no sturm und drang, no sounds and sensations of the powertrain right at the edge of maximum capability. Just sidestep the brake and enjoy the AMG amusement park.AMG Aerokinetics comprises a range of fixed and active aerodynamic panels. Rear diffuser is fed by aero elements that comprise a full-length belly pan, there’s an active panel under the chin, and an active rear spoiler, all of which help keep those four big gummy tires firmly planted on the pavement, delivering over 1100 horsepower with ruthless efficiency.Mercedes-Benz AGTOP SPEEDIf you are a truly bold adventurer, GT 63 tops at 186 mph with the optional AMG Performance Package. Sure, any number of piston-engine supercars can vault 30 or 35 mph higher, into the 220s, but how often does that really take place outside a few stretches in Europe or the Middle East? Not too often in the U.S. if you want to keep a license. And with a maximum velocity below 200 mph, AMG GT 63 is well within the bounds to be shod with gummy tires that perform equally well in cornering. The tires here will not be narrowly focused on surviving speeds of 220 mph or more. Beyond phenomenal acceleration—acceleration no one dreamed possible 15 years ago—GT 63 should deliver balanced performance. You can even bring along a couple of petits in the rear seat.GT 63 has all the expected advanced aero, suspension and electric powertrain systems found in AMG vehicles.Mercedes-AMG GT 63 4-Door Coupé dash panel creates a cockpit sensibility, with touchscreen readouts angled to driver. Anyone familiar with Mercedes subsystems will feel comfortable here in a short period of time.Mercedes-Benz AGAEROKINETICSAMG Aerokinetics comprises a range of fixed and active aerodynamic panels. Rear diffuser is fed by aero elements that comprise a full-length belly pan, there’s an active panel under the chin, and an active rear spoiler, all of which help keep those four big gummy tires firmly planted on the pavement, delivering over 1100 horsepower with ruthless efficiency.Of course such performance will consume charge rapidly. It should prove no different than driving a gasoline hypercar with massive fuel injectors squirting gallons of fuel under heavy throttle. Inevitably, the gas gauge drops precipitously and one begins to consider being stranded on a lonely road. Making use of over 1470 lb.-ft. of torque will draw down the battery.BATTERY TECH DERIVED FROM FORMULA ONEBut here again thanks to the science now at work in the greater Mercedes product development system, the elongated and liquid-cooled cells of the GT 63’s 800-volt battery pack can charge from 10 to 80 percent in about 11 minutes when hooked up to a rapid-charger.Most of the credit goes to the lads at AMG’s Brixworth, England battery technology center, which supplies AMG racing. But AMG has evolved into arguably the best and most efficient means of cascading racing technology into production cars, and that means considerable integration of several engineering and research groups. Credit also goes to engineers at AMG in Affalterbach, to the lessons of the Mercedes-AMG ONE hypercar program, and to lessons learned form the Formula One team itself, and also the mainstream Mercedes EV engineering efforts. This “AMG High Performance Electric Battery” (AMG HP.EB) is the key to the vehicle’s outstanding performance. Only two other companies on earth have this sort of feedback loop from racing to road car, and they are both tiny companies. To achieve this in an enterprise as big as Mercedes is an unprecedented organizational achievement.Why seven calibration settings in a hypercar? In the Driving Miss Daisy calibration setting using tip-toe throttle application, Mercedes expects GT 63 will have a range over 400 miles. Why does that matter? Well, to reach beautiful lonely roads, one must often cover 10, 20 or more miles of boring highway. The most thrifty setting allows conservation of charge for use on the mountain playground. If I am graced with a test car in 2027, I will use the thrifty setting till I reach the first big power bends of my favorite mountain road.SYNTHETIC SOUNDSMuch like the Mercedes G 580 all-electric Geländewagen I drove more than a year ago, GT 63 has a synthetically generated V8 aural signature. Sound is fully synchronized with rate of acceleration, providing aural information about just how quickly you’re moving. We drive not only with hand and foot inputs and our eyes, but by feel in the internal gyroscope, and sound.ADVANCED MIXED MEDIA BODY STRUCTUREAMG GT 63’s body structure is completely new, a mix of aluminum, steel and fiber-reinforced composites that provide high rigidity with low weight.

That’s just about as German as you can get.Sindelfingen is also home to MANUFAKTUR, the Mercedes custom shop, and the GT 63 can be built to taste with a wide range of colors, materials and interior finishes to create a one-of-one 4-door hypercar.
