Mercedes-AMG C 63 SE Performance 2023: the perfect balance between electricity and fuel


The Mercedes-AMG C 63 S had a lot to offer German saloon enthusiasts looking for the perfect balance between luxury and pure V8 fun.

Like everything going on in the industry today, this guilty pleasure of internal combustion is increasingly short-lived. And Mercedes-AMG had to redesign the C 63 S to keep up with the times.

Now featuring the complex C 63 SE Performance, the less powerful C-Class tries to fulfill its mission by retaining the hot engine, but increasing the hybrid. And not just any!

We spoke to Jochen Hermann, Technical Director at Mercedes-AMG, about some of the technical aspects of the new C 63 SE Performance.

Equality that favors performance over efficiency

The question arises: why has Mercedes-AMG not unveiled the fully electric C 63?

“AMG will soon have its own electric platform. But for now, the step is too big. We are still working with the C-Class chassis and we can still do a lot with it. Converting it to all electrics would not be a good idea at the moment,” says Hermann.

Therefore, Mercedes-AMG has created a “Frankenstein” type, with a power train that increases internal combustion and combines it with electric motion. First of all, the 2.0-liter turbo four-cylinder engine isn’t the one you’ll find in the traditional C-Class, and on its own it produces up to 469 horsepower, making it the most powerful turbocharged four-cylinder engine on the planet.

The C 63 SE Performance also has an electric motor located on the rear axle, powered by a 6.1 kWh battery. So, the 4MATIC+ all-wheel drive system is included, but it’s different from all other existing all-wheel drive systems – it’s basically a combination of mechanics and electrics.

Like some luxury cars on the market, it has a “virtual” limited slip differential that can distribute torque effectively by adjusting the electric module at the rear. However, there is still a link between the front and rear axles. loss of grip occurs on the rear axle, the power of the electric motor can also be transferred to the front to compensate.

The combined power of the system is equal to 671 horsepower when the Overboost function is enabled. The maximum torque of the system is 752 lb-ft, which allows this C 63 to go from 0 to 100 km / h in just 3.4 seconds.

The Overboost feature is basically a charge from the battery that sends an extra 80kW of power for 10 seconds at a time. In normal mode, the combined power is still 561 horsepower. However, AMG ensures that the recovery systems are so good that the system can be deployed repeatedly. We will definitely have to prove it!

The 400V system opens up a world of hybrid possibilities

Mercedes-AMG has brought together almost everything the automotive world has to offer in terms of hybrid technology. Typically, mild hybrid systems that focus on efficiency-enhancing features such as turbochargers and 48V power transmissions. The C 43 AMG, on the other hand, has an electric turbocharger assisted by a 48V motor to increase response and reduce lag. On the C 63 SE Performance, 400V is available to supply these electrical systems.

A lot of work has gone into the battery, which borrows two key elements from the manufacturer’s technical development in the Formula 1: performance per kilogram and an advanced cooling system that perfectly controls the temperature. This battery is mounted above the electric motor on the rear axle and weighs only 89 kg with a power-to-weight ratio of 1.7 kW (2.3 hp) per kg. Finally, the battery has a cooler that cools each 560 cell individually.

Performance The C 63 SE can drive in all-electric mode. But considering the importance placed on performance, it will only allow you to make a distance of 13 kilometers. “Maximum range is not a priority, but drivers can use this mode to drive home wisely, or even leave in the morning without disturbing the neighbors”, explains Jochen Hermann.

But what about AMG’s signature sound…?

If you’ve ever driven an AMG, you know that the exhaust note plays an important role in the driving experience. And as high-performance cars move toward electrification, the mechanical sounds from big-engined cars are giving way to smaller sounds.

The C 63 SE’s performance is set with a pressure sensor in the exhaust linked to the mufflers to enhance the four-cylinder’s rumble. But as Jochen Hermann says, it’s not about the simulated V8 sound. “The car will have its own sound signature. But more than that, sound is associated with emotion. And drivers will have to rely on every part of the car to experience AMG.”
