The Mercedes-AMG C63 and its four-cylinder plug-in hybrid drivetrain can be faraway from the vary reportedly on account of European rules.
In an interview EdmundsMichael Schiebe, CEO of Mercedes-AMG, stated the in-house tuner can be “changing our four-cylinder” with “no hybrid engine (however a) pure inline six-cylinder”.
He informed the American web site the C63 can be, successfully, changed by a brand new C53 mannequin powered by the engine used within the CLE53 two-door. The C53 is predicted to make its world debut within the second half of 2026.

The CLE53 is powered by a 3.0-litre turbocharged straight-six engine aided by a 48V gentle hybrid system, which in whole makes 330kW and 600Nm. It’s hooked as much as a nine-speed automated and an all-wheel drive system, permitting the coupe to finish the 0-100km/h sprint in 4.0 seconds.
By means of comparability, the advanced plug-in hybrid system within the C63 S E-Efficiency makes a complete of 500kW and 1020Nm, and is able to slingshotting the automobile from 0-100km/h in 3.4 seconds.
Presumably Mr Schiebe’s remarks concerning the purity of the engine refers back to the lack of a plug-in hybrid system, because it appears doubtless the C53 will hold the CLE53’s gentle hybrid setup.

Regardless of the overwhelmingly destructive suggestions from on-line commenters, Mr Schiebe says the AMG’s resolution to axe the four-cylinder plug-in hybrid drivetrain is as a result of upcoming Euro 7 emissions rules.
“Underneath the rules of EU7, it’s fairly troublesome to hold (the four-cylinder PHEV drivetrain) into the long run,” Mr Schiebe stated. “That’s why we’ll cease providing the ‘M139’ and within the mid-size phase we’ll substitute it with the inline six-cylinder.”
This appears to be an attention-grabbing spin on issues given the Euro 7 guidelines accepted in 2025 are considerably weaker than they have been envisaged to be throughout the C63’s improvement.

In reality, the Euro 7 rules carry over the check situations and exhaust emissions limits from Euro 6. The primary adjustments relate to brake particle emissions limits for automobiles and vans, minimal efficiency necessities for battery sturdiness in electrical and hybrid automobiles, and new tyre abrasion requirements.
A report on the finish of 2025 claimed the C63’s drivetrain can be axed on account of new noise rules in Europe.
With the C63 going the best way of the dodo, the GLC63 will doubtless head the identical approach with a brand new GLC53 variant taking its place.
