Mercedes AMG had an almost American quality to their engines with their sound and power. But recently, plans have changed. Efficiency and electrical are the way forward and AMG is changing too. Depending on the car and the driverthis means that the Twin-turbo V8 in the C 63 will soon be gone.

There was a time when Mercedes AMG used model names that actually referred to the respective engine power of that model. The number 63 used to designate the M156 naturally aspirated 6.2-liter V8. All AMG models ending in 63 from the late 2000s through the mid-2010s used this engine. But then 63 was thrown out the window in the mid-2010s in favor of downsizing 4.0-liter twin-turbo V8 with a hot vee (the turbos sit between the cylinder heads) set up. This engine has been used in all 63 models (and some non-Mercedes models) since 2015. Now rumor has it that this engine will be replaced in AMG’s 63 models.

According to Driverthe 2023 C63 will draw its power from a turbocharged I4. Although this engine is used in CLA/GLA 45 models, Car & Driver says the C63 configuration will reflect the SL and the C 43 models which use a 400-volt electric turbocharger on the engine. It’s a trick Mercedes learned from racing that causes turbo boost to appear before the exhaust gas. They claim that because of this there will be no turbo lag. The setup doesn’t stop there.

The 400 volts that will power the turbocharger through a hybrid system with a rear-mounted electric motor with a small battery positioned above that they claim can deliver an additional 200 horsepower in 10 seconds. AMG claims this setup will result in “at least 442 horsepower.” This same setup will also be used on the 4.0-liter V8 to create 73 AMG models, according to Car and driver. It’s an interesting setup for sure. But you can’t beat the sound of those V8s. And all of that ultimately adds weight and complexity to vehicles that are meant to be performance cars. In any case, we will we have to wait and see until it becomes official.
