🚗 Mercedes-AMG Confirms End of the Four-Cylinder C63 & Engine Shake-Up –

Kokila Chokkanathan
Mercedes-AMG has officially confirmed that the controversial four-cylinder plug-in hybrid powertrain in the current AMG C63 is being discontinued, marking the end of that engine era for the performance middata-size sedan. Here’s what it means for enthusiasts and the AMG lineup.

🔥 1. Farewell to the Four-Cylinder C63

Mercedes-AMG CEO Michael Schiebe has acknowledged that the four-cylinder turbo plug-in hybrid used in the AMG C63 will be phased out and replaced with a new powertrain. This move essentially ends the short-lived era of compact four-cylinder AMG flagship engines.

⚙️ 2. Hello, Inline-Six Power

Instead of the downdata-sized four-cylinder, Mercedes-AMG will introduce a naturally aspirated inline-six engine in a new performance model — likely named C53. This engine comes from the AMG CLE 53 and uses a 3.0-liter turbo straight-six setup.

  • Expected to produce 443 hp and 413 lb-ft (560 Nm) in its current form.
  • AMG may even tune it for 500+ horsepower to keep performance exciting.
🔄 3. Why Mercedes Is Shifting Gears

The four-cylinder C63 didn’t resonate well with AMG’s traditional fan base — many drivers felt the smaller engine lacked the character, sound, and emotional appeal typical of AMG cars. CEO Schiebe admitted the company overestimated customer acceptance of the four-cylinder setup.

Additionally, compliance with stringent upcoming Euro 7 emissions and noise regulations has made it harder to justify keeping the complex hybrid four-cylinder alive.

🚀 4. What Happens to the C63 Nameplate?

Although the current four-cylinder C63 is being discontinued, Mercedes has not ruled out a future return of the V-8-powered C63 down the road. A new 4.0-liter twin-turbo V-8 engine — compliant with modern emissions rules — has already been confirmed for other AMG models and may eventually power future performance sedans.

🆕 5. What’s Next: The C53 & Beyond

  • The C53 with the straight-six will act as the new AMG performance C-Class — likely sitting between the regular C-Class and any future V-8 flagship.
  • AMG’s lineup is pivoting back toward six- and eight-cylinder engines, balancing performance, sound, and compliance with emissions.
  • Rumors suggest a revived V-8 C63 might still be in the works for future generations, but details are not yet official.
📊 What This Means for Fans

✔ The four-cylinder experiment is ending after poor reception and regulatory challenges.
✔ AMG is refocusing on engines with more character — straight-sixes and possibly revived V-8s.
✔ The replacement C53 marks a fresh start for AMG’s compact performance sedan range.

📌 Bottom Line

Mercedes-AMG is bringing the four-cylinder C63 era to a close and pivoting toward inline-six power and potentially a return to V-8s as it adapts to shifting customer tastes and tightening regulations — a major shift for AMG’s iconic performance lineage.
