Mercedes has only revealed the mainstream version of the 2022 C Class, but details of the next C63 are starting to trickle out. A new report suggests the new C63 will feature 550 horsepower thanks to a really complex four-cylinder powertrain.
It’s already been confirmed all variants of the new C Class will feature four-cylinder power, including the AMG cars. Expect to see Mercedes’ familiar 2.0-liter inline-four as the foundation of the new C63. However, the similarities with other Mercedes powertrains ends there. The rest of this C63 powertrain is quite different.
According to CAR, there will be three electric motors included in the C63 powertrain. One will act as a starter-generator to capture energy from the brakes. Another electric motor will rest at the rear axle with the ability to spin the rear wheels independently of the gas engine. The third motor will sit with the engine’s turbocharger, assisting in spooling it up and capturing energy from the exhaust system. Electric turbochargers are already used on Formula One cars.
Each of these motors will have access to a battery pack. The battery is likely to even include plug-in capabilities, making this the first plug-in hybrid from AMG.
The combined output of this complex system is rumored to be 550 horsepower and 590 pound-feet of torque. If true, that’s a significant increase from the 503 horsepower and 516 pound-feet of torque found in today’s C63 S. That said, it is notable that this new powertrain is going to add mass. In fact, the report says it will add around 550 pounds of heft, bringing the C63’s total weight to around 4,400 pounds.
Despite the added pork, the C63 is expected to hit 60 mph in about 3.5 seconds with a top speed of 180 mph. The current C63’s nine-speed automatic and mechanical all-wheel-drive system are expected to aid in the effort as well.
Expect to hear more details on the next C63 later this year or early next. A lesser AMG variant is also expected.
