New AMG V8 Returns CLE 63 Mythos Exhaust Sound Revealed

The latest testing activity around the Mercedes-AMG CLE 63 Mythos at the Nürburgring is starting to paint a very clear picture of what Mercedes-AMG is building, and it feels like a deliberate return to form. This is not just another performance coupe. From what has been seen during testing, this car looks like something much more focused, almost like a spiritual successor to the wild Black Series era that enthusiasts still talk about today.

Watching the prototype attack the track, even under heavy camouflage, you can already tell the intent. The stance is wider, lower, and far more aggressive than anything in the standard CLE lineup. The front end appears to have been opened up significantly, with large air intakes designed to manage cooling under extreme conditions. Along the sides, the body looks stretched outward, suggesting a wider track for better grip and stability. Around the back, the quad exhaust outlets and pronounced diffuser give it that unmistakable AMG presence, but with a sharper, more track-focused edge.

What stands out the most is how purposeful everything looks. This is not just design for style. Every vent, every curve, and every surface seems to serve a function. There are clear signs of aerodynamic development, including what appears to be a vented hood and the possibility of a large rear wing in later production form. These are the kinds of details you expect from a car that is being engineered for serious lap times, not just straight-line performance.

Under the surface is where things get even more interesting. The CLE 63 Mythos is expected to bring back a proper V8 engine, something many enthusiasts felt was missing in recent AMG models. This new setup is rumored to be a 4.0 liter twin turbocharged V8 with a flat plane crankshaft, which is a big shift in character. A flat plane design typically allows the engine to rev higher and respond more sharply, giving it a more exotic feel compared to traditional AMG engines.

Power figures are expected to exceed 650 horsepower, and when you combine that with all wheel drive and advanced chassis tuning, it becomes clear that this car is being built to perform at a very high level. The Nürburgring testing is a strong signal that Mercedes-AMG is targeting more than just impressive numbers on paper. They are aiming for real performance, the kind that shows up in lap times and driver feedback.

Another layer that makes this car even more intriguing is its place within the Mythos lineup. This is not just a higher trim level. The Mythos badge represents a level of exclusivity that goes beyond even the usual AMG offerings. Production is expected to be extremely limited, possibly around 30 units, which immediately places it in a category closer to collector cars than everyday performance vehicles. Pricing will likely reflect that, pushing it into supercar territory.

When you step back and look at the bigger picture, the CLE 63 Mythos feels like a statement. After experimenting with smaller engines and hybrid systems in some models, Mercedes-AMG appears to be listening closely to its core audience. This car brings back the elements that made AMG special in the first place: a powerful V8, aggressive design, and a focus on driving experience above all else.

Testing at the Nürburgring is not just a routine step in development. It is where performance cars prove themselves. The fact that this car is being pushed hard on one of the most demanding tracks in the world tells you everything about its mission. This is not about compromise. It is about building something that can stand alongside the best performance machines out there and remind everyone what AMG is capable of when it goes all in.
