Mercedes-AMG C63 to Ditch Four-Cylinder for Inline-Six
Mercedes-AMG is confirmed to be phasing out the four-cylinder C63, a decision influenced by both market reception and regulatory pressures. The successor model, expected to be named the C53, will feature a 3.0-liter turbocharged inline-six engine, marking a departure from the complex plug-in hybrid setup of its predecessor. This shift promises a lighter, more traditional driving experience, potentially rekindling enthusiast interest.
The move away from the four-cylinder hybrid powertrain is not an admission of enthusiast rejection, but rather a strategic response to evolving emissions standards. The upcoming C53 will leverage a pure internal combustion engine, drawing its powerplant from the CLE 53, and will debut with the C-Class facelift. This strategic change aims to balance performance with compliance, while also hinting at a renewed focus on the brand's V8 heritage.
The End of an Era: Four-Cylinder C63 Discontinued
The four-cylinder Mercedes-AMG C63, a model that generated considerable discussion among automotive enthusiasts, is officially being phased out. This development comes after widespread speculation and signals a significant shift in AMG's powertrain strategy. The decision was confirmed by AMG's CEO, Michael Schiebe, who indicated that the current electrified four-cylinder engine will be replaced. This marks the end of a controversial chapter for the C63, which, despite its impressive combined output from the hybrid system, struggled to gain universal acceptance among purists.
The current C63's plug-in hybrid system, while powerful with 671 horsepower, added significant weight and complexity, making it less appealing to some traditional AMG buyers who valued raw power and a simpler, lighter platform. Schiebe clarified that the discontinuation is not primarily due to enthusiast disapproval of downsizing, but rather the increasing difficulty of adapting the smaller engine to meet the stringent Euro 7 emissions regulations. This regulatory hurdle has prompted AMG to re-evaluate its approach, leading to a new direction that prioritizes compliance without compromising on performance, paving the way for a new, more balanced model.
Introducing the C53: A Return to Inline-Six Power
In place of the outgoing four-cylinder C63, Mercedes-AMG is preparing to introduce the C53, a new model that will feature a pure gasoline setup with an inline-six engine. This change represents a strategic pivot, as the new C53 will integrate a turbocharged 3.0-liter M256M engine, previously seen in the CLE 53. While the C53's power output is yet to be finalized, the CLE 53 variant produces 443 horsepower and 413 pound-feet of torque. This new engine configuration aims to offer a more engaging driving experience, characterized by reduced weight and the linear power delivery traditionally associated with inline-six engines.
The decision to move to an inline-six without hybrid assistance is expected to result in a considerably lighter vehicle compared to the current C63, which weighs in at a substantial 4,817 pounds (2,185 kilograms) in U.S. specifications. This weight reduction is anticipated to enhance the car's agility and responsiveness, appealing to enthusiasts who prioritize a purer driving dynamic over sheer hybrid-boosted power figures. The new C53 is slated to launch alongside the C-Class facelift, and while a V8 C63 is not immediately planned, AMG has confirmed ongoing development of a new V8 engine, suggesting a promising future for the brand's high-performance offerings.
