Daimler has capped the engine displacement for the 2021 Mercedes C-Class to 2.0-litre, which applies to the spirited 2022 Mercedes-AMG C43 and the fire-breathing 2022 Mercedes-AMG C63. Every future 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.
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.
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. Theoretically, with this setup, 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.
