Power Shift

The Mercedes AMG C63 is currently moving away from its V8 roots with the introduction of a plug-in hybrid setup. This iteration houses a turbocharged 2.0-liter four-cylinder engine paired with a rear electric motor, complemented by a 6.1 kWh battery and 4MATIC+ all-wheel drive system. The total power output reaches an impressive 671 horsepower and 752 lb-ft of torque, making it a formidable player in the hybrid luxury segment.
Farewell, V8

While it’s a bummer for V8 enthusiasts, the shift to a more eco-conscious powertrain reflects current trends. The existing C63 S E Performance starts at about $86,050, which might seem steep considering it houses a four-cylinder engine. Sales haven’t quite hit the mark, leading Mercedes to consider swapping the 2.0-liter for a twin-turbo 3.0-liter inline-six. This potential upgrade hints at a more potent variant, reminiscent of powerplants in other models like the E53 but presumably with increased muscle.
Tech Update

Proposed changes for the facelifted AMG C63 extend beyond just the engine. The vehicle is slated to ditch the rear-mounted electric motor for a version located between the engine and transmission. Although this could decrease overall output, speculation points to figures still north of 650 horsepower and 650 lb-ft of torque.
Under the Hood
With the next C-Class facelift set for next year, the new engine arrangement will be shared with the anticipated 2027 GLC 63. Expecting a return to the V8 is off the table due to space limits. Implementing the twin-turbo 4.0-liter engine would necessitate significant structural revisions and further regulatory testing, a hefty price for a platform nearing its next generation.
Driving Feel
The AMG C63 has traditionally been about unadulterated power accompanied by a raw driving experience. Equipped with its smaller hybrid setup, it initially felt like a downgrade from the V8 thrills most purists crave. The inline-six hybrid stands to bring back more of that visceral Mercedes AMG aura. Its aggressive acceleration and handling might remind fans of the classic Munich Autobahn sprints but with an eco-friendly nod.
Comparatively, the 2025 Mercedes AMG C63 holds its ground against competitors like the BMW M4, which boasts a similar power range. However, the six-cylinder lineup may yet need to prove it can deliver that deep, throaty exhaust note synonymous with AMG machines.
