Mercedes-AMG looks close to adding a much harder-edged chapter to the CLE story.
The upcoming CLE 646 Mythos is expected to make its first public appearance in Spain around the Formula 1 Madrid Grand Prix weekend, and early images suggest this won’t be a discreet special edition.
It’s wide, visibly aero-led and appears positioned as a more focused flagship for AMG’s coupe line.
At a glance
- Mercedes-AMG is expected to reveal the CLE 646 Mythos in Spain around the Formula 1 Madrid Grand Prix weekend.
- The CLE-based coupe features a widebody treatment, aggressive aero, a fixed rear wing and track-influenced detailing.
- Power is expected to come from an AMG-tuned flat-plane-crank 4.0-litre twin-turbo V8, with the 646 name possibly hinting at output.
A CLE with a much wider stance
The CLE 646 Mythos takes the familiar Mercedes coupe silhouette and gives it a far more confrontational presence.
The front end is dominated by a large, low-slung grille, giving the car a more serious visual attitude than the regular CLE models.
A vented hood, swollen arches and fender louvres push the design further into AMG’s performance territory.
The widebody kit is the key visual move here, not just because it adds muscle, but because it separates the Mythos from the cleaner grand touring character of the standard CLE.
Aero cues with a track-minded edge
The front splitter is paired with canards, signalling that the CLE 646 Mythos is being styled around downforce rather than decoration alone.
At the back, AMG has fitted a more assertive bumper treatment with an integrated diffuser.
The fixed rear wing is the most dramatic element, sitting high and broad, with a small gurney between its two supports.
It’s the kind of detail that shifts the car’s character from fast road coupe toward something more specialised, even before Mercedes-AMG confirms the final performance figures.
What the 646 badge may be suggesting
The CLE 646 Mythos is expected to use an AMG-tuned version of the new flat-plane-crank 4.0-litre twin-turbo V8.
That engine choice matters because it would place the car firmly in AMG’s upper performance tier and give the Mythos a very different personality from the brand’s electrified four-cylinder performance models.
The number 646 may also be a clue to the power output, though Mercedes-AMG has not confirmed the final figure.
If that interpretation proves accurate, the CLE 646 Mythos would sit as a serious halo model for buyers who want AMG theatre in a more focused two-door package.

The CLE 646 Mythos appears to be aimed at AMG loyalists who want something more extreme than a conventional performance coupe, but still rooted in the brand’s road-car language.
If the final car keeps the attitude shown here and pairs it with the expected V8, it could become one of the most closely watched AMG reveals of the year.
