Mercedes-AMG has delayed announcing the return of V-8 engines in the C63 and E63 models, though the company confirmed the powerplant is coming. Leadership attributed the hold-up to prioritizing validation of the updated flat-plane crank V-8 in other applications first, ensuring the engine demonstrates sufficient refinement and sophistication before deployment in its most prestigious sedan lineup.
The strategy reflects Mercedes' cautious approach after years of downsizing and electrification across its performance range. The brand switched the C63 and E63 to four-cylinder turbocharged engines with hybrid assistance, a move that disappointed purists but aligned with emissions targets. Now, with the flat-plane crank V-8 proving itself in other AMG models, Mercedes wants to cement its credentials as a high-revving, sonically superior powerplant before formal announcements.
This phased rollout protects Mercedes from repeating engine-related missteps that plagued competitors. By letting the V-8 prove its durability and smoothness across the broader AMG portfolio first, the company avoids launching the C63 and E63 variants only to face reliability questions or customer disappointment. The flat-plane crank design inherently produces a distinctive wail at high RPMs, a signature trait AMG wants to highlight rather than defend.
The delay also gives Mercedes time to finalize hybrid integration. While the company hasn't confirmed whether the returning V-8 C63 and E63 will pair with electrification, the trend in performance vehicles points toward some form of hybrid assistance for emissions compliance and additional horsepower.
For enthusiasts, the message is clear. The V-8 C63 and E63 are coming, but Mercedes controls the timing carefully. By ensuring the engine impresses in earlier models, the company builds market confidence before bringing it to its
