In a surprising but welcomed move, Mercedes-AMG is reportedly bringing back the V-8 engine to its high-performance C63 model as early as 2026. This comes after widespread criticism of the brand’s decision to downsize to a four-cylinder hybrid powertrain, which has failed to resonate with customers.
A V-8 Revival: Mercedes Listens to Enthusiasts
According to a recent report from Autocar, AMG is actively developing a new V-8 engine, which could make its way into the next-generation C63. The information has yet to be officially confirmed, but AMG spokesperson Catrin Dunz-Ludwig acknowledged the brand’s commitment to an eight-cylinder future.
“We can confirm that AMG is developing a new V-8 engine. However, we ask for your understanding that we do not comment on a detailed rollout plan,” said Dunz-Ludwig.
This development marks a dramatic reversal from previous statements by AMG leadership. Just last year, AMG CEO Michael Schiebe stood firmly behind hybridization, insisting that the C63 would retain its four-cylinder configuration. However, poor sales figures and customer dissatisfaction seem to have prompted a shift in strategy.
New V-8 with a High-Tech Twist
The upcoming V-8 is expected to be a heavily reworked version of AMG’s existing twin-turbocharged 4.0-liter engine. Reports suggest it will feature a flat-plane crankshaft, a design previously seen in the track-focused AMG GT Black Series. This setup should improve throttle response and high-revving capability while delivering a distinctive engine note—albeit one with a higher pitch than traditional cross-plane V-8s.
Additionally, the new engine is likely to incorporate mild-hybrid technology, which could mean the current plug-in hybrid system will be phased out. If true, this would eliminate the complex and weighty battery-assisted setup, making the car lighter and more engaging to drive.
The Current C63’s Struggles
Since its introduction, the four-cylinder, plug-in hybrid C63 has struggled to find its footing. The car’s 2.0-liter turbocharged engine, while powerful on paper, has failed to deliver the visceral driving experience AMG enthusiasts expect. Even with a combined output exceeding 650 horsepower, the hybrid system’s added weight and muted exhaust note have left many underwhelmed.
Sales figures in Germany have reflected this sentiment, with significant discounts being offered to move inventory. The backlash has been strong enough to force AMG to reconsider its direction—a rare instance of a brand course-correcting so soon after launching a major model.
Will the New V-8 Fit the Current C-Class?
One major challenge for AMG is whether the new V-8 can be integrated into the current C-Class platform, which was originally engineered for smaller engines. However, Austrian tuning firm VUK Manufaktur recently demonstrated that a V-8 swap is possible, completing a two-year project to fit the engine into the latest C-Class chassis.
This suggests that, with enough investment, AMG can successfully integrate the new powertrain without a full platform redesign. Given the potential for a resurgence in demand, it appears Mercedes is willing to make that investment.
What’s Next?
The CLE63 is rumored to be the first model to receive the new V-8, with the C63 following shortly after. There is speculation that the GLC63 SUV may also return to a V-8 configuration, abandoning its current electrified four-cylinder unit.
As Mercedes-AMG continues refining its high-performance lineup, this decision could mark a turning point for the brand. While electrification remains a long-term goal, the return of the V-8 proves that AMG is still committed to its performance roots—something that could win back the customers it lost.
Conclusion
By reintroducing the V-8, AMG acknowledges that horsepower figures alone don’t define a great performance car. The move signals a renewed focus on emotional driving experiences—something that the previous C63’s hybrid setup failed to deliver. If all goes as planned, 2026 could be the year AMG reclaims its place at the top of the sports sedan hierarchy.
