Mercedes-AMG is set to discontinue several of its four-cylinder high-performance models due to upcoming, stricter European Union noise regulations, according to an internal memo obtained by German publication Elektroauto-News. The changes will impact popular models like the GLA35, C43, and GLC43, with production slated to end in February 2026.
The decision stems from the implementation of Phase 3 of UN-R51.03, a new EU standard that significantly reduces permissible external noise levels for vehicles. While the document doesn’t mention six- or eight-cylinder AMG variants, it confirms that production of the GLA45 S will continue without restriction. More powerful models, including the C63 S E Performance and GLC63 S E Performance, will be produced until May 2026.
Why This Matters: The move highlights a growing trend in automotive regulations prioritizing noise reduction, driven by environmental concerns and quality-of-life improvements in urban areas. These regulations are forcing manufacturers to reassess their lineups, particularly high-performance vehicles known for aggressive exhaust notes. The shift could reshape the AMG brand, potentially pushing it further toward larger-displacement engines or electric alternatives.
The internal memo also suggests that Mercedes-AMG is preparing for a significant product overhaul. The company plans to launch an “extensive product offensive,” including new high-performance EVs and a “next-generation, high-tech electrified V8.” This suggests that AMG is adapting to the changing automotive landscape, with a focus on electrification and more sustainable performance solutions.
Future Models: The upcoming GLA, set for a 2026 reveal, will move to the MMA platform, along with the next-generation GLB and a potential A-Class replacement. The controversial C63 and GLC63 S E Performance models are reportedly set to swap their four-cylinder plug-in hybrid powertrains for a six-cylinder mill. The current four-cylinder S E Performance variants have faced weak demand and criticism for their excessive weight and sound.
Mercedes-AMG declined to comment on future product plans to Elektroauto-News, but the internal memo suggests that the company is actively preparing for the transition. The move to cut four-cylinder models could signal a broader shift in AMG’s strategy, prioritizing larger-displacement engines or electric alternatives to meet stricter noise regulations.
The changes will slash Mercedes-AMG’s range of four-cylinder models by more than half, raising questions about the future of smaller AMG variants. The internal memo indicates that replacement products are under consideration, but no specific details have been released.
Ultimately, these changes reflect a broader industry trend toward quieter, more sustainable performance vehicles. As regulations tighten and consumer preferences evolve, manufacturers like Mercedes-AMG must adapt to remain competitive
