The distinctive 4.0-liter eight-cylinder replaced the record-breaking two-liter four-cylinder with electric assistance, which delivers 680 horsepower!

When news first surfaced that the distinctive 4.0-liter rear-wheel drive V8 would replace the 2.0-liter four-cylinder of the next-generation Mercedes-AMG C63 with plug-in hybrid assistance, many feared the result. Today, however, the automaker has finally unveiled the car, and its parameters are impressive. The electrified four-cylinder engine transmits 680 horsepower to all wheels!
The basis of the power unit of the Mercedes-AMG C63 SE Performance model is a 2.0-liter AMG in-line four-cylinder with the designation M139L, which is equipped with an electrified turbocharger, supplemented by a 400 V electric motor. already equipped with a similar system, but while offering the maximum power of 381 hp, under the hood of the C63 SE Performance, the four-cylinder engine itself offers 476 hp and 545 Nm of torque.

With these parameters, the 2.0-liter four-cylinder not only matches the old 6.2-liter eight-cylinder of the AMG C63 S W204 generation, but also becomes the world record holder. It is the most powerful production 2.0-liter four-cylinder in the world. A nine-speed automatic transmission with wet clutches takes care of transferring its power to the 4Matic + all-wheel drive system, which appears for the first time in the AMG C63.
But the capabilities of the new AMG C63 do not end there. As we have already mentioned, it is a plug-in hybrid powertrain, with the four-cylinder in-line under the hood complemented by an electric motor on the rear axle, which promises a continuous power of 70 kW, 320 Nm of torque and a power maximum of 150 kW for a maximum of ten seconds.
The electric motor is integrated into the rear axle along with a two-speed gearbox and an electronically controlled limited slip differential. At the same time, the gearbox of the rear electric motor shifts to second gear when the speed of 140 km / h is reached, when the revs are around 13,500 min-1. In addition to the rear axle, the electric motor can also drive the front wheels.
The electric motor draws energy from a 400V battery with a capacity of 6.1 kWh, developed directly in AMG, located above the rear axle. The battery weighing 89 kilograms is equipped with a special cooling of about 14 liters of liquid to ensure an optimal temperature and therefore maximum battery performance. The purely electric range should be around 13 kilometers at speeds of up to 125 km / h. In practice the autonomy should be sufficient, for example for city driving, charging will be supported with a power of up to 3.7 kW.
The combination of these two powertrains produces combined power of up to 680 horsepower and 1,020 Nm of torque, making the new Mercedes-AMG C63 E Performance more powerful than the BMW M3 Competition and the larger BMW M5 Competition. The sprint to 100 km / h is promised in 3.4 seconds and the maximum speed is limited to 250 km / h as standard, but on request it can be increased up to 280 km / h. The combination of an electrified turbocharger and an electric motor on the rear axle should ensure a smooth start and a gradual gradation of power.

The chassis is equipped with adaptive shock absorbers and steel springs as standard, which should ensure adequate comfort and sufficient safety on the slopes. Also standard are the AMG workshop carbon composite brakes, which are six-piston on the front axle. The braking system should therefore ensure quick and sharp reactions, but in addition AMG also recovers under braking (in four intensity levels) and recharges the battery.
Also new is the rear axle steering system, which is capable of turning the wheels up to an angle of 2.5 degrees. At speeds up to 100 km / h, the wheels turn in the opposite direction to the front wheels, which ensures better maneuverability. At speeds above 100 km / h, the wheels turn up to 0.7 degrees in the same direction, which should increase stability at high speeds.
The car is also traditionally equipped with a drive mode selector, offering Electric, Comfort, Sport, Sport +, Race, Battery Hold or slippery road modes. The chassis, throttle response, brake response, steering and the entire powertrain are traditionally tailored to individual modes. A specialty is the Master driving mode, intended mainly for closed tracks, which ensures a slightly oversteer behavior of the car.
The passenger compartment of the car will offer AMG sports seats with special upholstery and stitching, optional second generation AMG Performance seats and, of course, a range of AMG accessories, including the possibility of a rich interior customization. The MBUX infotainment received new screens, optimized for the AMG model and the plug-in hybrid driving system. The instrument cluster and head-up display offer new graphics. Also standard is the two-spoke AMG steering wheel, which offers a button to quickly change the driving mode and the ability to easily adjust the intensity of recovery.
In terms of design, the new Mercedes-AMG C63 S impresses, for example, with a new ventilation opening on the hood, which distinguishes the C63 S engine from the weaker C43. There is also the traditional Pan-American radiator grille, behind which there are active slats that regulate the air flow, or an aggressive front bumper. But also the new AMG logo on the hood, which has replaced the traditional three-pointed star, should also be noted. The car is fitted with 19 “alloy wheels as standard, but 20” forged wheels are available on request.

In addition to the traditional sedan body design, the Mercedes-AMG C63 SE Performance will also be available as a more practical station wagon. Despite the larger body and 34 kilograms of extra weight, the station wagon version can accelerate to 100 km / h in the same 3.4 seconds, but the top speed does not exceed 270 km / h. Compared to the classic sedan and station wagon, the AMG C63 S models are exactly 83 millimeters longer, while the front overhang itself is increased by 50 mm. Both models are also 76mm wider thanks to a wider track and modified bodywork.
However, the weight, which we talked about long ago, could be one of the weaknesses of the new AMG C63 S. The combination of electrification, all-wheel drive, rich equipment, etc. contributed to the fact that the curb weight of the sedan reaches 2111 kilograms and we have fun with the station wagon at around 2145 kilograms. It will therefore be interesting to see how much the weight gain affects the handling and playability of the car.
Despite the heavier weight and extreme performance, the C63 S promises quite interesting running economy. The combined consumption of sedan and station wagon should be around 6.9 l / 100 km, electricity consumption around 11.7 kWh / 100 km and emissions should reach 156 g / km. So you won’t get electric brands with the AMG C63 in the Czech Republic, because AMG designers focused more on car dynamics than on ecology and economy.
