2022 Mercedes-AMG C63 & 2022 Mercedes-AMG C43 to be 4-cyl hybrids [Update]

Daimler has capped the engine displacement for the 2021 Mercedes C-Class to 2.0-litre, and this applies to the spirited 2022 Mercedes-AMG C43 and the fire-breathing 2022 Mercedes-AMG C63. Every next-gen Mercedes-AMG C-Class variant will employ 2.0-litre petrol engines electrified to compensate for the cylinders.

Currently, the Mercedes-AMG C43 sports a 390 PS 3.0-litre twin-turbo V6 engine, and the Mercedes-AMG C63 employs a 476 PS 4.0-litre twin-turbo V8 engine. Customers can have the latter in a hotter ’S’ configuration with a 510 PS 4.0-litre twin-turbo V8. Despite using four-cylinder engines, the successors to these AMG C-Class models are likely to be way more powerful and significantly more efficient.

Just days after the 2021 Mercedes C-Class broke cover, X-Tomi Design shows us a realistic rendering of the 2022 Mercedes-AMG C63. The AMG’d 2022 C-Class gets the signature radiator grille from Affalterbach with twelve vertical louvres and an AMG badge, functional air inlets for improved aerodynamics, and a sportier bumper at the front. On the sides, it flaunts AMG aero wheels in a 6-twin-spoke design and glossy black mirror housings.

On 31 March, Daimler made some interesting announcements at the TecDAY AMG Future of Driving Performance Independent E Performance event, indirectly giving out details about the 2022 C63 AMG. The company said that engineers are aiming to develop further the M139 engine such that it can once again break the record of the world’s highest litre output of all 4-cyl engines. The 63-series AMG variant of the C-Class will likely wear an E Performance label in the next generation.

The 2022 C63 AMG E Performance will sport a longitudinally installed, comprehensively modified M139 2.0-litre petrol engine with an electric exhaust-gas turbocharger. Derived from Formula F1, this turbocharger will have a 4 cm-narrower electric motor integrated directly on its shaft, between the turbine wheel on the exhaust gas side and the compressor wheel fresh air side. The electric turbocharger can achieve speeds of up to 170,000 rpm, enabling a very high airflow rate. It can maintain boost pressure even when the driver takes the foot off the accelerator or applies the brakes.

The benefit of electrification will be realized as an instant response from zero rpm and across the rev range. Higher torque from the word go means more agility and quicker 0-100 km/h (0-62 mph) acceleration compared to cars having an engine with a conventional turbocharger. With turbo lag virtually eliminated, the engine is more responsive across the rev range, and this means that the car’s driving character can be much more dynamic and agile. A 400-volt onboard power supply will feed the electrified turbocharger. The turbocharger, electric motor, and power electronics will be connected to the cooling circuit of the engine so that an optimized temperature environment can be maintained.

The 2022 C63 AMG E Performance will have a battery-powered drive motor at the rear axle as well, and the battery powering this motor will reportedly be rechargeable. In other words, the first-ever C63 AMG with a 2.0-litre engine is a plug-in hybrid that customers can silently drive in pure electric mode.

There will be a third motor, a belt-driven starter-alternator (BSG), or Riemengetriebene Starter-Generator (RSG) in German, in the 2022 C63 AMG E Performance. The RSG will produce 10 kW (14 PS), start the combustion engine, and power the auxiliary components like AC and driving lights.


Daimler has confirmed that the upcoming AMG 2.0-litre turbo engine can generate more than 330 kW or 449 PS and that AMG can team it up with an electric drive motor developing up to 150 kW or 204 PS. With this setup, theoretically, it is possible to achieve a combined power of about 480 kW or 653 PS.

Alternatively, the company may cap the figure around 450 kW/612 PS and save the maximum achievable power for future use, say a mid-cycle refresh, or release a special variant like Black Series. A 9-speed automatic transmission will be standard.

2022 AMG C43 or 2022 AMG C45

An entry-level AMG version of the new C-Class (either the 2022 AMG C43 or 2022 AMG C45, in line with the nomenclature of the A-Class AMG A45) is planned, which would use the same engine. What the C45 won’t have, reportedly, is the rear-mounted electric motor of the C63, meaning the output would be significantly lower.

2022 Mercedes C-Class AMG Release date

The 2022 Mercedes-AMG C43 could enter production later this year, while the 2022 Mercedes-AMG C63 will follow next year. We’ll update this page as more information surfaces.
