Mercedes-AMG is developing a flat-plane V8-powered CLE 63 Mythos model intended to outperform the BMW M4 [1, 3].
The project represents a strategic move to satisfy customer demand for high-displacement powertrains in an era of electrification. By targeting the compact-coupe segment, Mercedes-AMG seeks to reclaim performance dominance from its primary German rival [1, 3].
Development is centered at the Mercedes-AMG facility in Affalterbach, Germany [2]. The Mythos is positioned as a top-tier variant of the CLE lineup, drawing comparisons to the legacy of the CLK Black Series [2].
Technical specifications remain under wraps, but reports indicate the vehicle could produce over 700 horsepower [4]. The use of a flat-plane crank V8 is a significant engineering choice, typically reserved for supercars to allow for higher revs and a distinct exhaust note.
There is conflicting information regarding the exclusivity of this engine. Some reports suggest the V8 will be limited strictly to the Mythos version to maintain its status at the top of the lineup [2]. Other reports indicate the eight-cylinder engine is making its way into other models, which would mean the powertrain is not exclusive to the Mythos [3].
Observers have noted prototypes featuring an exposed carbon roof, signaling a focus on weight reduction, and aerodynamics [1]. The vehicle is designed to compete directly with the BMW M4, focusing on track-capable performance and luxury [1, 3].

The introduction of the Mythos suggests that Mercedes-AMG is hedging its bets against a full transition to electric power. By reviving high-output V8 engines for limited, top-tier models, the company can maintain its brand prestige among enthusiasts while continuing its broader electrification strategy.
