The Ultimate Horizon | Mercedes-AMG Teases the Ultra-Rare CLE 63 Mythos Coupe

Mercedes-AMG has unsealed the first teaser images of the CLE 63 Mythos, the second entry in its collector-grade Mythos portfolio. The wide-body coupe pairs a flat-plane crank 4.0L twin-turbo V8 surpassing 650 horsepower with a production run rumored as low as 30 units, positioned above the Black Series.

For decades, the pinnacle of Mercedes-AMG performance was defined by two words: Black Series. Those rare, track-widened, aerodynamically aggressive weapons represented the absolute limit of what the engineering team could extract from a street-legal platform. But as the automotive landscape shifts toward high-end bespoke customization, the German luxury house is drawing a brand-new top tier.

Mercedes-AMG has officially unsealed the first teaser images of its second entry in the highly exclusive, collector-grade Mythos portfolio: the Mercedes-AMG CLE 63 Mythos. Following the footsteps of the radically roofless, SL-based PureSpeed speedster, this new creation takes the sleek silhouette of the standard CLE coupe and morphs it into an uncompromising, track-bred monster that serves as a direct course correction for the brand's performance purists.

The Clarification | A Bewinged Hardcore Coupe, Not a Speedster

While initial design rumors speculated that the second Mythos vehicle might adapt another open-top speedster format, the newly unsealed winter-testing dispatches from Scandinavia have set the record straight. The upcoming Mythos is a hardtop, wide-body grand touring coupe built to echo the raw mechanical posture of the legendary 2008 CLK 63 AMG Black Series.

  • Base Layer: Standard AMG performance models, such as the CLE 53.
  • Intermediate: Traditional track limits, the Black Series heritage.
  • Ultimate Tier: Mythos Series, bespoke collector-grade, low-volume halos.

The design modifications are immediate and severe. The prototype vehicles showcase massively widened front and rear fenders housing integrated heat-extractor vents, a heavily revised Panamericana vertical grille, and a full carbon-fiber roof panel to slice the vehicle's center of gravity.

The defining focal point, however, sits squarely on the decklid: a towering, motorsport-derived swan-neck adjustable rear wing working in tandem with a functional underbody diffuser to lock in massive high-velocity downforce.

The Big News | The Return of the Flat-Plane V8

Beyond the aggressive visual updates, the engineering choice driving the massive hype cycle surrounds what rests beneath the heavily vented hood. Following intense pushback from performance purists over the implementation of complex, heavy four-cylinder hybrid systems in lower segments, AMG is utilizing the Mythos program to execute a definitive celebration of pure internal combustion.

The CLE 63 Mythos will debut a heavily untuned version of Mercedes' return-to-form 4.0-liter twin-turbocharged V-8 engine.

  • Engine Architecture: 4.0L biturbo V8 with flat-plane crankshaft technology.
  • Target Output: Surpassing 646 to 650 horsepower and 800-plus Nm of torque.
  • Target Acceleration: 0-100 km/h in comfortably under 4.0 seconds.
  • Exhaust Architecture: Deep-breathing trapezoidal quad exhaust tips.

Crucially, this iteration incorporates advanced flat-plane crankshaft technology. By shifting the crank geometry, the engine layout significantly alters its firing order, enabling the V8 to rev faster, breathe more efficiently at high RPMs, and emit a sharp, mechanical exhaust wail reminiscent of an endurance race car rather than a traditional cross-plane muscle car rumble.

Power will be channeled via a lightning-fast 9-speed multi-clutch transmission down to an overbuilt, wide-track rear-axle platform loaded with semi-active hydraulic roll stabilization systems.

Unmatched Rarity and Hypercar Pricing

Because the Mythos sub-brand is tailored strictly for the upper echelon of global car collectors, these vehicles will never sit on standard dealership showroom floors.

While final regulatory numbers are still being formalized ahead of the vehicle's official commercial rollout, internal dealer leaks indicate that production could be capped anywhere from a tight 250 units globally down to an ultra-scarce run of just 30 units.

Operational ParameterMercedes-AMG CLE 63 Mythos Baseline Specs
Chassis FoundationModified wide-body execution of the midsize CLE platform
Aero FrameworkMotorsport-grade carbon fiber body kit, swan-neck wing, diffuser
Interior TreatmentLightweight bucket seats, integrated structural safety cage
Estimated PricingExpected to scale comfortably out of normal range into hypercar space

By building an ultra-exclusive halo car that prioritizes raw emotional mechanical connection over clinical battery efficiency, Mercedes-AMG is sending a clear signal to the rest of the industry: at the absolute top of the luxury ladder, there is still no substitute for the theater of a roaring, track-widened, and uncompromised land rocket.
