Mercedes-AMG is reportedly ending production of the four-cylinder C63 plug-in hybrid after just a few years on the market. The decision, confirmed by internal memos, aligns with growing criticism of the model’s lack of traditional AMG character and stricter European noise regulations.
Production Timeline
According to Elektroauto News, Mercedes will discontinue several four-cylinder AMG models by 2026. The C43, GLC43, and GLA35 will end production in February, while the C63 and GLC63 will follow in May. The GLA45+ remains unaffected. The move is largely driven by new UNECE noise limits, which will reduce permissible external noise levels. Internal documentation states that these regulations prompted the discontinuation dates for select AMG engines.
Why This Matters
The four-cylinder C63 was widely criticized for its subdued exhaust note and departure from AMG’s historically powerful engines. While technically advanced, it failed to capture the visceral experience enthusiasts expected. This decision reflects a broader trend: automakers are increasingly constrained by emissions and noise regulations. The shift forces brands to balance performance with compliance, often at the expense of traditional engine character.
The Engine Debate
The current C63 uses a 2.0-liter turbocharged four-cylinder paired with an electric motor, producing 671 horsepower. However, many purists argue that the engine lacks the soul of previous AMG models. The company itself has acknowledged this disconnect. In June, Mercedes executives admitted that the four-cylinder C63 was not resonating with enthusiasts.
A Return to Larger Engines?
Mercedes has signaled a potential shift back to larger engines. In a recent statement, Mathias Geisen, Member of the Board of Management for Marketing & Sales, hinted at a future C63 with a more substantial powertrain. While a V-8 remains unconfirmed, a powerful V-6 is now a strong possibility.
Electrification and Future AMG Models
Mercedes remains committed to electrification, but the company appears willing to compromise on engine size to retain enthusiast interest. Future AMG models will likely continue to incorporate hybrid technology, but with more emphasis on raw power and exhaust note. The decision to kill the four-cylinder C63 suggests that Mercedes is listening to its core audience.
Looking Ahead
The discontinuation of the four-cylinder C63 marks a turning point for AMG. While electrification will remain central to the brand’s strategy, future models will likely prioritize character and engagement over pure efficiency. The next C63, whether with a V-6 or another larger engine, will need to deliver the visceral experience that enthusiasts crave
