The Mercedes-AMG C63 is well into its development programme and prototypes of the saloon and estate variants have been spotted at the Nürburgring.

The performance-oriented C63 was previously seen testing on the road and is pictured in the same exterior camouflage, with the wheels, grille and aggressive front and rear lights on display. The roof on both models has also been left on display, in silver for the saloon and black for the estate. 

The C63 is set to be the first AMG model to feature an advanced four-cylinder hybrid drivetrain instead of its long-standing V8 power when it goes on sale in early 2022. The car will be one in a line of future new AMG models earmarked to receive an electrified version of Mercedes’ new turbocharged 2.0-litre M139 engine. 

The camouflaged prototype shows an evolutionary look in line with the recently facelifted E-Class and suggests that AMG will not tone down the saloon's aggressive styling as it downsizes the engine.

The potent four-cylinder engine kicks out a maximum of 416bhp and 369lb ft of torque in non-electrified form in the new A45 and its related siblings. The unit has already been engineered for longitudinal mounting as well as mild-hybrid electric boosting. It’s destined to be used in not only the next C63 but also, in a less heavily tuned form, in a follow-up to today’s turbocharged 3.0-litre V6-powered C43.

The new C63 will be offered in saloon, coupé and convertible bodystyles, with the next C43 likely to be sold in those three guises as well as an estate version.

Other AMG models set to run the new electrified driveline include successor models to today’s GLC 43 and GLC 63 SUVs, the GLC 43 Coupé and the GLC 63 Coupé.

Autocar has been told the M139 engine will adopt a 48V integrated starter motor similar to that already used by the turbocharged 3.0-litre in-line six-cylinder M256 unit, which powers the CLS 53 4Matic+ and other recent new AMG models.

In the CLS 53 4Matic+, the gearbox-mounted starter motor provides an additional 22bhp and 184lb ft of electric boosting. In the next C63, however, it is set to be tuned to provide significantly more power in combination with a similar torque loading.

The new EQ Boost hybrid drivetrain is also planned to run in combination with Mercedes’ nine-speed torque-converter MCT Speedshift gearbox.

Affalterbach insiders with knowledge of AMG’s new model plans suggest the new four-cylinder hybrid drivetrain will match the existing second-generation C63 4Matic’s V8 engine in outright power, at a maximum of 503bhp. This is despite a 50% reduction in swept capacity and cylinder count. With the benefit of electric boosting, it has also been conceived to deliver up to 553lb ft of torque – a 37lb ft increase on today’s C63 S 4Matic.

The entire C-Class range is powered exclusively by electrified four-cylinder engines, with plug-in and mild-hybrid technology rolled out across the range for better efficiency and thus reduced emissions.

Details about the C63 remain limited, although the new driveline is thought to adopt a lithium ion battery of higher capacity than the 0.9kWh unit used by the CLS 53 4Matic+. It is also expected to use a more advanced energy recuperation system that harvests kinetic energy at each wheel.

Back to top

One of the most significant advantages in the adoption of the new electrified driveline is a reduction in weight over the front axle of the new C63 4Matic.

At 160.5kg, the M139 four-cylinder unit weighs 48.5kg less than the M177 V8 engine used by today’s C63 4Matic. Even with the addition of the hybrid architecture, including a disc-shaped electric motor and power electronics, the overall weight of the new powerplant is claimed to undercut that of today’s unit.

Additionally, the new powerplant’s weight is concentrated lower, which aids efforts to bring about a lower centre of gravity for the new model, theoretically improving its agility and body control. Further development plans for the next C63 4Matic include a new four-wheel drive system to provide a fully variable apportioning of power front to rear. This will allow AMG to engineer the new model with rear-wheel-drive properties in certain driving modes, much as with the larger E63 sibling. AMG has indicated that all its next-generation models will adopt this system, moving away from pure rear-driven models due to customer demand for all-wheel drive.

The decision to provide the C63 4Matic with four-cylinder power was apparently driven by Mercedes-Benz as part of rapidly escalating efforts to reduce fleet CO2 emissions while harnessing the engineering lessons pursued during the development of the Mercedes-AMG One hypercar.

Well this takes Lexus approach...

...puts it on steroids! They were the kings of 'take a smaller engine, add a hybrid and reach the power out put of the next class above'. Take a 4 cylinder, add a hybrid and you get V6 power, with 4 cylinder fuel economy! Take a V6, add a hybrid and get V8 power, with V6 fuel economy; and so on. But take a high out put 4 cylinder, and a hybrid and super car V8 performance? That's a new trick! While there's nothing like the sound of a powerful V8, how many will give that up for the improved performance and handling and possible better fuel economy? I'm sure that for those who can drop this kind of money for a vehicle are not worried about fuel, but with BEV's around the corner (along with automakers making heavy investments in their creation), these may be the last days of the high out put ICE vehicles!

When high out put...

...4 cylinders are all you have...you take what you can get!

I wouldnt say Lexus were the kings of anything. 

Certainly in Europe they have achieved little in terms of sales....so as a blueprint for the future, Lexus is a poor business model.

Its not new Volvo have been doing it for a few years with their 400bhp PHEV models, and the 600bhp Polestar 1, makes AMGs figures seem fairly lame to be honest..

Hope this

Will be a Porsche thing...and they'll go back to something bigger shortly!
