V8-Powered Mercedes-AMG CLE Mythos Prototype Spotted During Winter Testing

Mercedes-Benz has confirmed that the second installment of its ultra-exclusive Mythos series is currently undergoing cold-weather evaluation in Sweden. Based on the CLE Coupe platform, the upcoming model follows the 2024 PureSpeed speedster as the next limited-production offering from the German manufacturer’s bespoke division. While visual cues link it to the existing CLE 53, the prototype’s configuration suggests a significant mechanical upgrade, most notably the return of eight-cylinder power to the CLE lineup.

Powertrain and Mechanical Upgrades

The primary distinction for the Mythos-series CLE is expected to be its drivetrain. While the current CLE 53 utilizes a 3.0-liter turbocharged straight-six, this new variant is anticipated to house a 4.0-liter twin-turbo V8. Technical specifications suggest the use of the M177 Evo engine recently debuted in the S-Class facelift, which features a flat-plane crankshaft and a 48V mild-hybrid system. In its sedan application, this unit generates 537 hp and 750 Nm of torque, though the CLE Mythos will likely receive a higher-output calibration. To support the increased performance, engineers are implementing a reinforced drivetrain and a revised suspension geometry.

Design and Aerodynamic Refinements

Camouflaged test mules reveal several aerodynamic and aesthetic departures from the standard AMG CLE models. The front fascia incorporates a more prominent Panamericana grille and an aggressive splitter designed for high-speed stability. Notable exterior features include:

  • A fixed rear aerodynamic wing for increased downforce.
  • Trapezoidal quad-exhaust outlets integrated into a new rear diffuser.
  • A lowered ride height and a wider track for improved mechanical grip.
  • A staggered wheel and tire arrangement.

Interior Technology and Safety

The cabin is expected to retain the core layout of the CLE 53 while introducing Mythos-specific trim, including extensive use of carbon fiber and suede upholstery. The vehicle will likely debut with the new Mercedes-Benz Operating System (MB.OS), featuring integrated artificial intelligence. Expected hardware and safety features include:

  • AMG adaptive suspension and rear-axle steering.
  • Carbon-ceramic braking system.
  • A 64-color ambient lighting system and Burmester surround sound.
  • A comprehensive safety suite featuring eight airbags and advanced driver assistance systems (ADAS).

Production and Launch Timeline

Consistent with the Mythos brand strategy, the V8-powered CLE will be produced in strictly limited numbers, positioning it above the standard AMG catalog in terms of price and exclusivity. While official pricing has not been disclosed, the global reveal is scheduled for the second half of 2026.
