Mercedes-AMG is reportedly making a significant shift in its engine lineup by phasing out its four-cylinder hybrid powertrains in favor of more traditional inline-six and V-8 engines. This move marks a return to the brand’s roots, responding to mixed reactions and sales struggles associated with the current four-cylinder AMG models. The change aims to balance modern performance demands with the emotional connection enthusiasts expect from AMG vehicles.
In recent years, Mercedes-AMG embraced engine downsizing to meet increasingly strict emissions regulations and electrification goals. The most notable example was the introduction of the AMG C 63 S E Performance, powered by a 2.0-liter turbocharged four-cylinder hybrid engine producing an impressive 671 horsepower. This powertrain was highly innovative, combining small displacement with electric boost to deliver raw power and improved efficiency. However, despite its technical merits, the engine faced criticism from many AMG purists and performance enthusiasts who felt it lacked the distinctive character and visceral appeal that larger AMG engines traditionally provide.
Feedback from loyal customers and automotive experts suggested that while the four-cylinder hybrid was a progressive step environmentally, it did not embody the soul of an AMG. This perception led to a noticeable decline in sales and a growing disconnect between the brand’s image and its flagship models. In response, AMG has reportedly decided to refocus its powertrain strategy on engines that better align with its performance heritage.
The upcoming AMG C-Class facelift, expected in 2026, will reportedly replace the current four-cylinder hybrid with a more robust 3.0-liter inline-six hybrid engine. This inline-six is anticipated to deliver power figures comparable to the outgoing four-cylinder but will offer a smoother, richer sound and more engaging driving experience. By combining a traditional engine layout with modern electrification, AMG aims to provide the best of both worlds—emissions compliance without sacrificing the emotional appeal AMG is known for.
More notably, Mercedes-AMG is also planning the return of the V-8 engine, albeit initially limited to specific models. While fitting a conventional V-8 into the existing C-Class platform has proven difficult due to packaging constraints, the upcoming CLE 63 coupe and GLC 63 SUV are expected to feature a new-generation 4.0-liter twin-turbo V-8 with a flat-plane crankshaft. This design choice allows for higher revving capabilities and a more aggressive exhaust note, which many enthusiasts have been craving since the downsizing trend began.
The new V-8s will be electrified with mild-hybrid technology, allowing AMG to maintain strong performance figures while improving fuel efficiency and emissions. The flat-plane crankshaft layout differs from the traditional cross-plane design found in previous AMG V-8s, offering a sharper throttle response and a distinct, race-inspired engine sound. This combination promises to restore the emotional connection AMG fans expect while meeting the realities of modern emissions standards.
This strategic shift reflects AMG’s recognition that while electrification is the future, emotional engagement remains a vital part of its brand identity. Rather than fully abandoning internal combustion engines, AMG is seeking a balanced approach—offering electrified inline-sixes and V-8s that provide both performance and passion. The company believes this path will satisfy regulators, enthusiasts, and the market at large.
The transition is expected to unfold over the next couple of years. The refreshed C-Class AMG models will debut with the inline-six hybrid powertrain, followed closely by the introduction of the new V-8 in the CLE and GLC performance models. This phased approach allows AMG to gradually bring back the characteristics that made its cars legendary while adapting to the increasingly electrified automotive landscape.
By recommitting to larger engines enhanced by electrification, Mercedes-AMG is signaling that it values the emotional appeal and driving experience that have long been its hallmark. In a time when many performance brands are moving toward full electrification, AMG’s move to revive the inline-six and V-8 shows that there remains a place for traditional engine architectures—especially when combined with modern technology.
Ultimately, this shift could redefine AMG’s future, blending the best elements of classic performance with the innovation required for tomorrow’s mobility challenges. For AMG enthusiasts around the world, the return of the inline-six and V-8 engines is likely to be welcomed as a reaffirmation of the brand’s commitment to delivering exhilarating driving experiences for years to come.
