Mercedes-AMG C63 Set to Ditch Hybrid Four-Cylinder, Embrace Six-Cylinder Power

The Mercedes-AMG C63 is poised for a powertrain overhaul, ditching its controversial four-cylinder plug-in hybrid setup. This move comes after consumer backlash and sluggish sales figures, signaling a potential return to a more traditional, and perhaps beloved, engine configuration.

Hybrid Heartbreak

Reports indicate that the plug-in hybrid powertrain, initially introduced to the C63, will be phased out. A senior Mercedes-AMG employee revealed the unpopularity of the current system, which has struggled to gain traction with buyers despite its impressive performance statistics. Dealers have been offering substantial discounts to move the cars.

The current 2.0-litre unit, which replaced the 4.0-liter bi-turbo V8, has not been well-received. Buyers have expressed their preference for the older engine. This change has led to price cuts, with some dealers offering reductions of up to £9,500.

Customer Concerns

The company’s CEO, Michael Schiebe, admitted the need for better communication regarding the four-cylinder hybrid technology. He acknowledged that some customers find it challenging to accept the new system. The hybrid’s substantial curb weight, combined with reported overheating issues at high speeds, further contributed to the problem.

“Technically, the four-cylinder is one of the most advanced drivetrains available in a production car. It’s also right up there on performance. But despite this, it failed to resonate with our traditional customers. We’ve recognised that,”

Despite the advanced engineering, the plug-in hybrid has struggled to resonate with buyers. The United Kingdom has seen discounts up to £9,500, and in the US, the car has been offered at reduced prices. In the first quarter of 2024, the C63 sales dropped by 20% as compared to the same period last year, reflecting the buyer dissatisfaction.

The Six-Cylinder Revival

As a replacement, a six-cylinder engine is planned. This new powertrain will likely be a 3.0-liter plug-in hybrid, similar to the one in the AMG CLE 53. The V8 engine is not expected to make a return, the forthcoming AMG CLE 63 will reportedly feature a mild-hybrid-assisted V8 with a reported output.

Though there’s no official confirmation from Mercedes-AMG yet, more details are expected later this year. The move to six-cylinder engines could signify a shift back towards engines that have stronger ties with the brand’s legacy.
