Doug DeMuro gives the 2024 Mercedes-Benz C63 AMG a mixed 59/100 rating, praising its design elegance and exceptional interior quality while expressing serious reservations about the car itself. The C63 excels in design (100/100) with its understated aesthetic and distinctive AMG logo light show, and delivers a masterclass in performance dynamics with 670 horsepower, 0-60 in around 3 seconds, and the "tremendously responsive" MBUX infotainment system (76/100 cabin tech). However, DeMuro's core criticism is damning: at nearly $887,000, the switch from a twin-turbo V8 to a turbocharged 2.0L plug-in hybrid 4-cylinder engine represents a misstep that undercuts the car's identity, delivering only 6 miles of electric range and failing to justify the price point for what defines an AMG muscle car. This car is for wealthy buyers who prioritize Mercedes' design language, interior craftsmanship, and technological sophistication over the visceral, powerful engine character that traditionally justified the C63's premium.

Throttle House gave the 2024 Mercedes-AMG C63 S a decidedly negative review (34/100), finding it fundamentally misguided despite some technical achievements. The car excels in raw performance—producing 671 horsepower and achieving a 3.3-second 0-60 time—and impresses with fuel efficiency at under 10 liters per 100km for a nearly 700-horsepower vehicle, yet these strengths are undermined by poor livability, with the 4,600-pound sedan feeling overweight and suffering from jittery ride quality in Comfort mode that lacks any benefits typical of hybrid powertrains. Major drawbacks include a controversial design that looks "melted" with its reversed grille, an expensive price tag around six figures that reviewers say isn't justified, and excessive technology that "gatekeeps" driving with constant beeping and warnings. The C63 S is essentially for no one—Throttle House couldn't identify a single buyer who would actually want these hybrid changes, making it a car that fails to satisfy enthusiasts while delivering none of the traditional C63 character.
