A turning point in Affalterbach in Baden-Württemberg: Up until now, Mercedes-AMG, the sports department of the Stuttgart-based car manufacturer, has relied on large-volume and powerful gasoline engines since it was founded in 1967. But that is changing with stricter emissions standards and the overall increasing political pressure and a zeitgeist that is conscious of climate neutrality. This is why the traditional Swabian brand is now consistently relying on electrification and downsizing.

The 4.0 liter V8 was typically AMG

The upcoming C 63 should be symbolic of this development. Large engines have a long tradition in the sporty top model of the C-Class. Ever since the C 55 AMG (W202) from the late nineties, Mercedes-AMG has topped the mid-range model series with powerful eight-cylinders in terms of performance. With the model change from the W204 generation to the recently discontinued W205, the first critical fan voices were loud six years ago. At that time, the Affalterbach company decommissioned the 6.2 liter naturally aspirated engine, which was revered for its powerful sound and even power delivery. A smaller and now charged eight-cylinder unit served as a replacement. The four-liter twin-turbo V8 with a capacity of 510 hp in the C 63 S has served the Swabians as an all-purpose weapon in recent years.

Displacement and cylinders are halved

However, this change was nothing compared to what Mercedes-AMG has planned for the successor. The top model of the last week presented and now the seventh C-Class generation W206, is to be unveiled at the end of the year and delivered from the beginning of 2022. The C 63 is expected to be available as a coupé, sedan and station wagon. It has been speculated for over a year that the model change will cut both the number of cylinders and the displacement in half.

At the end of January 2020, the then AMG boss Tobias Moers was interviewed by the specialist magazine “Auto Motor und Sport”. When asked whether the C 63 will lose the V8 engine, he answered back then: “Let’s put it this way – performance is being redefined in this segment.” Five months earlier, he told the Malaysian auto journalist Paul Tan at the 2019 IAA already reveal that the up to 421 hp and two-liter turbo engine of the compact A 45 will also power larger series in the future. The most powerful production four-cylinder in the world is to have electric support in models with the larger rear-wheel drive platforms, such as the C 63, as well as being installed lengthways instead of crossways. This design should ensure excellent traction and minimize the drive influences in the steering.

The regular C-Class will also only be offered with four-cylinders in the future.

There is more than 550 HP system output

The British medium Car Magazine has now published new information on the technology and specific performance data of the electrified sports model. The output of the A 45 four-cylinder in the most powerful C-Class is expected to be increased to around 420 hp with an equally responsive e-turbo and passed on to the front and rear axles via the standard nine-speed automatic. Most of the power, however, is passed to the stern. There is also the additional electric motor, which transfers its output of over 200 hp directly to the rear wheels. The bottom line should be a system output of around 550 hp and almost 800 Newton meters. This would outperform its main competitors, the competition versions of the BMW M3 and M4, by a whopping 40 horses.

The new C 63 weighs almost two tons

The electrical components are not simply taken over from the plug-in hybrid version of the normal C-Class. Instead, the C 63 has a modern 400 volt architecture that shortens the charging process and increases the purely electric range to up to 65 kilometers. The battery and the electric motor together weigh around 250 kilos. So the total weight should increase to almost two tons. However, this should be compensated for by the ideal weight distribution of 50:50. According to Car Magazine, the most powerful C-Class should sprint to a hundred in around 3.5 seconds with a full battery. The predecessor took about half a second longer for this discipline.

As with its predecessor, the top speed should be electronically blocked at 250 km / h. Like the compact A 45 S, the C 63 is to have a special drift mode as standard. Visually, the future top model from Mercedes mid-range should be based on the facelift of the E 63 presented in 2020. There is one thing that AMG fans will have to make admittedly: Even with a sophisticated sound design, the sound of the forced-ventilation four-cylinder engine should not come close to the fervor of the characteristic V8.

The competitor BMW M3 still has a classic straight six under the hood.
