Performance First, Electrified Second: The AMG GLC 63 S E
Not a retreat from performance, but a recalibration of how it’s delivered.

In the pale light of an early morning start, the Mercedes-Benz GLC 63 S E Performance feels less like a provocation and more like a proposition—quiet, contained, waiting. There’s no V8 shattering the stillness anymore. Instead, the SUV eases forward on electric power, rolling out with the restraint of something that knows exactly what it’s capable of and sees no reason to announce it yet.
This restraint is the misdirection. The new GLC 63 S E is not a retreat from performance but a recalibration of how it’s delivered.
The familiar twin-turbo four-litre V8 has been replaced with a plug-in hybrid powertrain that’s shared, largely, with the C 63 S. At the core is a turbocharged two-litre four-cylinder that generates 469 horsepower, a seemingly impossible figure for a tiny engine that hints at how far internal combustion has been pushed.
An electric motor integrated into the turbocharger enables smoother response, creating something closer to anticipation than reaction. At the rear axle, a second electric motor draws energy from a compact 6.1-kWh battery, lifting total output to 671 horsepower and 752 lb-ft of torque. Side note: That’s one heckuva lot.
But the numbers, in this case, explain very little. What matters is how seamlessly the system behaves. Power delivery is uninterrupted, elastic, and calm, without the awkward handoff that defines many plug-in hybrids. Acceleration builds cleanly, without spikes or surges, as if the driveline were a single, continuously tightening cable. Mercedes quotes a 0–100 kilometres per hour time of some 3.4 seconds—barely quicker than the outgoing V8 model—but the experience feels more controlled and far less theatrical.
The five drive modes reveal the logic behind the engineering. Comfort behaves as a genuine hybrid state, the engine cycling in and out as conditions dictate. Electric mode keeps the combustion engine dormant, relying solely on the rear motor. The available power from the electric motor alone, 201 horsepower, is sufficient for city driving and passing, though patience is required if you suddenly demand everything at once. The Sport, Sport+, and Race modes keep the gas engine alive continuously, replenishing the battery through use.
Performance here is not borrowed from electricity—it is reinforced by it. This is where the Formula One analogy becomes more than marketing shorthand. The battery’s cooling system borrows from Mercedes-AMG’s F1 program, designed for rapid charge and discharge rather than sustained range. Here, electrification is used as a force multiplier, not an efficiency exercise. As a result, the all-electric range of the GLC 63 S E is brief enough to feel incidental. For buyers whose priorities lean toward quiet commutes and daily fuel savings, Mercedes already offers a more appropriate solution: the GLC 350e, whose larger battery and longer electric range make it the rational choice for everyday efficiency. The 63 S E is pursuing a different brief entirely.
On the road, the weight implied by that hardware rarely announces itself. Adaptive dampers read surface imperfections fluently, avoiding the punishing stiffness that afflicts some rivals. Optional active roll stabilization slashes body roll and reduces brake dive to an absolute minimum. Rear-axle steering sharpens turn-in at low speeds and settles the car at higher speeds, operating quietly enough to disappear into the background.
The steering itself is quick and well weighted, though it stops short of conversation. The transmission, smooth in normal driving, snaps through upshifts when provoked, the paddles offering engagement without demanding constant attention. It is a drivetrain that rewards trust more than micromanagement.
Inside, AMG resists the urge to dramatize. The cabin mirrors the logic and material quality of the standard GLC, elevated by supportive performance seats and subtle trim changes. The on-board MBUX infotainment system dominates the dash with crisp graphics and deep menus, including AMG Track Pace, a telemetry suite capable of displaying everything from steering angle to lateral G-forces. Overkill for an SUV, perhaps, but consistent with the car’s ambitions.
What lingers after a morning behind the wheel is not nostalgia for the V8 but respect for the intent. The exhaust note lacks the sheer drama of the old engine, of course, and no amount of technology will replace that particular soundtrack. But the new GLC 63 S E feels authentically engineered, not compromised—an SUV that treats electrification as a tool for speed, response, and control.
I look forward to the next generation of plug-in hybrids from Mercedes-Benz, ideally one that brings this level of performance together with a longer electric horizon, without dulling the edge that makes cars like this worth waking up early for.
