The four-cylinder Mercedes-AMG C63, a plug-in hybrid model, faced a less-than-enthusiastic market reception. Described by critics as a technical marvel devoid of passion, this iteration of the C63 is now reportedly slated for discontinuation. Mercedes-Benz appears to acknowledge the feedback, as insider reports suggest the model, among others in the AMG lineup, will soon cease production.
According to reports from Germany, Mercedes-Benz plans to halt the manufacturing of the C63 PHEV after only a few years on the market. An internal document, reportedly circulated in October, outlines the phasing out of several four-cylinder AMG variants. The C43, GLC43, and GLA35 models are expected to conclude production by February 2026, with the C63 and GLC63 following suit in May 2026. The GLA45+ appears to be the sole four-cylinder AMG model not impacted by this decision.
A key factor driving these production changes is the impending enforcement of stricter noise regulations in Europe, mandated by the United Nations Economic Commission for Europe (UNECE). The internal memo explicitly states that new rules will lead to a reduction in external noise limits, necessitating the discontinuation of certain AMG engines to comply with these environmental standards.
For automotive enthusiasts who favor more robust powertrains, this development comes as welcome news. The fate of the four-cylinder C63 has been a subject of speculation, with numerous rumors pointing to Mercedes exploring options for a larger engine in future performance sedans. Mercedes executives had previously conceded that the four-cylinder C63 had not resonated well with its target audience. Subsequent remarks from Mathias Geisen, a Board Member for Marketing & Sales, hinted at the possibility of a more substantial engine for the next C63, with a powerful V-6 being a strong contender, even if a return to the V-8 remains unconfirmed.
While specific details regarding the next-generation C63 are still emerging, it is evident that Mercedes-Benz has taken enthusiast feedback seriously. The brand's commitment to electrification will continue, but there is an optimistic outlook that future AMG models will integrate their electric power with more emotive and larger-displacement engines, aiming to recapture the essence that fans felt was missing.
