Mercedes-AMG Brings Back the V8 with a Futuristic Twist

Hello, speed and innovation enthusiasts! Today, I bring news that made my enthusiast heart beat faster: Mercedes-AMG, known for its high-performance machines, is bringing back the glorious V8 engine, but with a modern touch of mild hybrid technology. It’s quite a twist, especially after the bet on smaller engines that, let’s say, didn’t warm everyone’s hearts.

The AMG Engine Saga: A Brief Retrospective

Anyone who follows the automotive world knows Mercedes-AMG’s tradition of producing V8 engines that are true engineering masterpieces. They’ve become icons, synonymous with visceral performance and that distinctive growl that gives you chills to the core. Models like the C63 and AMG GT, with their 4.0-liter biturbo engines, have cemented this reputation beyond doubt.

However, in recent years, growing pressure for lower emissions and stricter environmental regulations has pushed the brand to explore new paths. One example was the C63’s four-cylinder hybrid system, launched in 2022. Despite delivering an impressive 671 horsepower, it faced criticism mostly due to the lack of the “V8 excitement” and the extra weight from the battery. The reception wasn’t warm, and sales in Europe fell short of expectations — a clear sign that consumers still crave the dynamics and unmistakable sound of V8s.

The New Mild Hybrid V8: Fascinating Details

In a move I consider brilliant, Mercedes-AMG announced the return of the V8, now revamped with mild hybrid technology. It’s set to debut in 2025 in the CLE63 coupe, and this powerplant promises to deliver at least 585 horsepower of pure excitement. But what makes this V8 so special beyond the hybridization?

One of the big innovations is the adoption of a flat-plane crankshaft. This setup, previously seen only in the AMG GT Black Series, allows the engine to reach higher revs and produce a sharper, more aggressive sound reminiscent of sports cars from brands like Ferrari. For those seeking a more engaging driving experience, this is big news! The mild hybrid technology, likely a 48-volt system, will assist with extra torque, smoother start-stop functionality, and regenerative braking, aiming for efficiency without sacrificing AMG’s soul. Models like the Mercedes-AMG GT 63 S E Performance already demonstrate how the brand marries brute force with electrification.

Comparison Table: New Mild Hybrid V8 vs. Previous V8

Feature	New Mild Hybrid V8 (2025)	Previous V8 (4.0L Biturbo)
Displacement	4.0 liters	4.0 liters
Estimated Power	≥ 585 hp	469–720 hp
Hybridization	Mild Hybrid (48V)	Mild (some)
Crankshaft	Flat-plane	Cross-plane
Emission Standard	Euro 7	Euro 6

This table shows that while power may vary, the new engine’s focus is on efficiency and compliance with upcoming Euro 7 standards, a crucial step for the brand’s sustainability in the high-performance segment.

Innovations and Controversies: The Sound of the Future?

Here we enter territory that may divide opinions: the possible use of artificial sounds. Yes, you read that right. To enhance the sound experience, especially since the flat-plane crankshaft tends to produce a higher-pitched tone, different from the traditional deep rumble of V8s, AMG may resort to speakers. It’s a trend in the industry, but will purists approve? Personally, I’m skeptical, but I understand the effort to meet expectations.

The switch to a flat-plane crankshaft is, by itself, a significant innovation for AMG’s broader lineup. Previously limited to ultra-sports cars or very special editions like the Mercedes-AMG GT APXGP, this feature now promises to democratize an even more visceral driving experience across other models in the brand.

Impact on the AMG Lineup: Who Will Receive the V8 Heart?

The first to be blessed with this new mild hybrid V8 heart will be the CLE63 Coupe, expected in 2025. This will undoubtedly strengthen Mercedes-AMG’s position in the coveted high-performance coupe segment. There was strong speculation about the C63 sedan adopting this engine in 2026, especially following the mixed reception of the current four-cylinder hybrid.

However, Mercedes-AMG has confirmed that, for now, the C63 will not receive the V8, which creates some uncertainty and, frankly, a bit of disappointment among many sedan fans. Other models, like the GLC63, are also rumored to get the new powerplant, but we’re still waiting on official confirmations. The strategy seems to be to keep the V8 for iconic models while exploring electric potential on the AMG.EA platform.

Enthusiast and Market Reaction: Relief or Skepticism?

The decision to bring back the V8, even as a hybrid, was widely seen as a direct response to enthusiasts’ prayers and criticism. Mercedes-AMG’s CEO Michael Schiebe himself admitted that despite the technical merits of the four-cylinder C63, it couldn’t provide the same emotional connection that previous V8s did. This shows the brand is listening to its customers.

This strategic shift reflects a delicate balance: satisfying consumers’ passion for the raw power and sound of V8s while also meeting sustainability goals and increasingly strict environmental regulations. The issue of artificial sound, however, will surely spark heated debates in forums and owners’ gatherings. Brands like Ferrari with its 296 Speciale also face the challenge of balancing traditional sound with new hybrid technologies.

The Future of Mercedes-AMG: Balance and Emotion

The introduction of this new mild hybrid V8 is an important milestone. It demonstrates Mercedes-AMG’s ability to adapt, incorporating modern technologies without abandoning the performance heritage that made it legendary. At the same time, the brand continues full throttle on developing fully electric high-performance models, like those coming from the AMG.EA platform.

In my view, the big challenge will be maintaining AMG’s unique identity in this fast and constantly evolving automotive landscape. Electrification is an irreversible path, and environmental regulations are becoming more prominent. This mild hybrid V8 emerges as an intelligent bridge between a glorious past and an electrified but still thrilling future. It’s a way of saying: “Yes, we are changing, but the AMG soul remains intact.” Even other performance-focused brands, like Porsche with its Singer builds, pursue this balance between tradition and modernity.

Main Benefits of the Mild Hybrid V8

• Greater fuel efficiency
• Reduction in CO₂ emissions
• Compliance with Euro 7 standards
• Electric torque assist
• Sporty sound (even if assisted)
• Preservation of the V8 legacy

Frequently Asked Questions (FAQ)

1. What is a mild hybrid V8 engine?
   It’s an internal combustion V8 engine assisted by a small electrical system (usually 48V) that improves efficiency, reduces emissions, and can provide an extra torque boost, without enabling pure electric propulsion over long distances.
2. Why did Mercedes-AMG decide to return to the V8 for some models?
   Primarily in response to consumers and enthusiasts who missed the excitement and distinctive sound of V8 engines in models that switched to smaller engines, such as the four-cylinder C63.
3. Will the new mild hybrid V8 have artificial sound?
   There’s a strong possibility, due to the flat-plane crankshaft which naturally produces a higher-pitched sound. AMG may use speakers to enhance the sound experience, bringing it closer to the traditional deep rumble expected from an AMG V8.
4. Which models will receive this new engine?
   The first confirmed is the CLE63 coupe, launching in 2025. Other models are rumored, but the C63 sedan is currently not on the list to receive this V8.
5. Does this engine meet new emission standards?
   Yes, the new mild hybrid V8 is designed to meet the stringent Euro 7 emission standards, ensuring its viability for years to come.

Looking at the overall picture, I see this move by Mercedes-AMG as a lesson in strategy and sensitivity. They not only acknowledged market feedback but also found a way to reconcile passion for the V8 with the unavoidable environmental demands. Mild hybrid technology seems to be the ideal solution for this transition, offering the best of both worlds: the untamed soul of a V8 with a touch of ecological responsibility. Now we just have to wait, and most importantly, listen to these machines in action!
