The New Mercedes-AMG® GT 63 S E Performance

June 5th, 2025 by

The Mercedes-AMG® GT 63 S E PERFORMANCE makes a bold statement in today’s automotive landscape. Weighing in at a staggering 4,806 pounds and delivering an astounding 1,047 lb-ft of torque, this hybrid grand tourer refuses to keep things light. It’s a supercar, a muscle car, and a monument to engineering excess all rolled into one. But is it too much for daily life? Let’s dig deeper.

A Closer Look at the Powerhouse

What’s under the hood leaves almost no doubt about this car’s intentions. At its heart lies a 4.0L twin-turbo V8 engine that churns out 603 horsepower. But this isn’t just any AMG® GT; it’s the E PERFORMANCE version, and that means hybrid power inspired by Formula 1 technology. Mercedes-AMG® added a 400-volt, 6.1 kWh battery system to boost the output to a jaw-dropping 805 horsepower. And yes, you read that correctly—1,047 lb-ft of torque.

These figures are more than impressive; they’re the kind that make you double-check the specs. “Those are truck numbers,” quipped Todd Deeken of Everyday Driver during his review. But, despite its hefty weight and enormous power, this isn’t a car that struggles to balance performance with practicality. It’s an engineering marvel that defies physics in the way it translates sheer brute force into an athletic driving experience.

Actually Athletic Despite the Weight

Weighing nearly 5,000 pounds, the AMG® GT 63 S doesn’t seem like a natural athlete. Yet, its rear-axle steering and finely tuned suspension pull off some impressive tricks. According to Paul Schmucker of Everyday Driver, “You’re aware of its weight, but it doesn’t matter.”

Its cornering capabilities and balance seem almost anti-physics, a sentiment echoed by Deeken, who likened the GT 63 S to “the luxury equivalent of the Nissan GT-R.” It’s fast, precise, and confidence-inspiring, regardless of its hulking frame. That said, it is an undeniable heavyweight in a market where agility often reigns supreme.

Luxury Meets Formula 1 Tech

The Formula 1 inspiration doesn’t stop at the hybrid powertrain. The interior reveals more tech wizardry with a steering wheel loaded with buttons, knobs, and haptic sliders straight out of an F1 cockpit. While this might excite racing fans, it’s not without its criticisms. Deeken, for instance, called out the lack of physical buttons, lamenting, “You know what works well for volume? A knob.”

It’s clear, though, that Mercedes-AMG® designed this car for drivers who want more than just horsepower. With its attention to detail, high-quality materials, and cutting-edge tech, the cabin is as much about the experience as the driving itself.

Is It Too Much for Everyday Use?

Now, here’s the big question. Can the AMG® GT 63 S fit into the daily lives of its drivers? With 805 horsepower and over 1,000 lb-ft of torque, even automotive enthusiasts are calling it “power you’ll never use.” Deeken put it bluntly, saying, “We are making cars so powerful now… that we’re never going to use full throttle.”

There’s also the matter of practicality. Despite its backseat, this is not a true four-seater. Schmucker himself joked that the rear seats are little more than a luggage tray with seat belts. Combine this with its weight and overwhelming power, and the AMG® GT 63 S might not be ideal for your busy downtown commute.

Final Thoughts

The Mercedes-AMG® GT 63 S E PERFORMANCE is an unapologetic machine built to thrill and awe. It’s less about practicality and more about making a statement. Yes, it’s heavy. Yes, it’s excessive. And yes, you might never use its full capabilities. But for those who crave cutting-edge tech, jaw-dropping performance, and a slice of the motorsport world, this grand tourer delivers.

While some might wish for a lighter, more analog experience, there’s no doubt that the AMG® GT 63 S embodies the pinnacle of what modern automotive engineering can achieve. And for that reason, it stands as one of Mercedes-AMG®’s most compelling creations to date.
