AMG C63 Will Get a V-8 Engine in 2026: In a surprising yet welcome move, Mercedes-AMG has confirmed that the C63 will return to its roots with a V-8 engine in 2026. This announcement comes after widespread criticism of the current C63’s four-cylinder hybrid powertrain, which left enthusiasts longing for the thunderous roar and raw power of the iconic V-8. Despite tightening emissions regulations, Mercedes has vowed to keep V-8 engines in its lineup, even tweaking them to meet the stringent Euro 7 standards. The new V-8, described as a “next-generation, high-tech electrified” unit, is expected to debut in the CLE63 later this year before making its way to the C63.
The decision to reintroduce the V-8 to the C63 marks a significant shift in strategy for AMG. The current C63, powered by a 2.0-liter four-cylinder plug-in hybrid, has faced backlash for its lack of character and soul, despite its impressive performance figures. AMG CEO Michael Schiebe admitted earlier this year that the brand lost customers after halving the cylinder count. The new V-8, rumored to feature a flat-plane crankshaft and mild-hybrid technology, promises to restore the C63’s status as a true performance icon.
According to Autocar, the V-8-powered C63 could arrive as early as 2026, with a mid-cycle update planned for 2025 to phase out the four-cylinder engine. The new powertrain is expected to be based on the existing 4.0-liter twin-turbo V-8 but with significant upgrades, including a more compact design and electrified components. This move signals AMG’s commitment to balancing performance and sustainability while catering to the desires of its loyal customer base.

2026 AMG C63 V-8 FAQs
1. Why is AMG bringing back the V-8 to the C63?
AMG is reintroducing the V-8 to the C63 primarily due to customer demand and the underwhelming reception of the current four-cylinder hybrid model. The previous generation of the C63, powered by a 4.0-liter twin-turbo V-8, was celebrated for its raw power, aggressive exhaust note, and emotional driving experience. However, the shift to a 2.0-liter four-cylinder plug-in hybrid in the current model alienated many loyal AMG enthusiasts. Despite its impressive performance figures (over 670 horsepower), the four-cylinder hybrid lacked the character and soul that define AMG’s performance heritage. By bringing back the V-8, AMG aims to reconnect with its core audience and restore the C63’s reputation as a true performance icon.
2. What is a flat-plane crankshaft, and why is it significant?
A flat-plane crankshaft is a type of crankshaft design where the crank pins are positioned 180 degrees apart, creating a more balanced and compact engine. This design allows the engine to rev higher and deliver a sharper throttle response, making it ideal for high-performance applications. The flat-plane crankshaft also produces a distinctive, higher-pitched exhaust note, reminiscent of racing engines.
In the context of the new AMG C63 V-8, the flat-plane crankshaft is significant because it enhances the engine’s performance and responsiveness. It also allows for a more compact engine design, which is crucial for fitting the V-8 into the C63’s chassis, which was originally designed for smaller engines. This design choice reflects AMG’s commitment to delivering a thrilling driving experience while meeting modern performance and efficiency standards.
3. Will the new C63 V-8 be a hybrid?
Yes, the new C63 V-8 will feature mild-hybrid technology, marking a shift from the current plug-in hybrid setup. The mild-hybrid system will include an electric motor integrated into the transmission, providing additional torque and improving fuel efficiency. Unlike the current plug-in hybrid, which relies heavily on electric power, the mild-hybrid system will prioritize the V-8 engine’s performance while offering the benefits of electrification, such as smoother stop-start functionality and reduced emissions.
This approach strikes a balance between performance and sustainability, ensuring the C63 remains competitive in an era of tightening emissions regulations. The mild-hybrid system will also enhance low-end torque, making the car more responsive in everyday driving conditions.
