The two-liter Mercedes-AMG C 63 will surpass the dynamics of the ancestor with a V8 – DRIVE

While the C 63 prototypes are being tested in a disguised form, outside illustrators are trying to predict the appearance of the model.

That new Mercedes-AMG C 63 will lose half of the cylinders at once and switch from a supercharged V8 4.0 engine to a 2.0 turbo four, we wrote back in 2019. Now Car magazine has got hold of interesting technical details about the most difficult C-class with the equally complex full name Mercedes-AMG C 63 4-Matic + EQ Power Sport. It should be presented by the end of this year and enter the market in 2022.

The tests have already seen both the C 63 sedan and the station wagon. However, before their premiere, the Germans still have to present a less extreme version of the C 43.

The system is based on the motor Mercedes-AMG 2.0 M 139 from A 45 Sbut changed. In particular, he will receive a combined electric turbocharging and an integrated starter generator (ISG). Only one internal combustion engine will be able to develop 425 hp, and it will be assisted by a 202-horsepower electric motor on the rear axle. In this case, the electric motor must operate independently of the all-wheel drive transmission with drift mode, which distributes the thrust of the turbo four between the front and rear axles. There will also be a fully electric driving mode with a power reserve of about 60 km.

The current “fifth” C-class is still presented as a station wagon and a sedan with several petrol and diesel turbochargers (1.5 M 264, 2.0 M 254 and 2.0 OM 654), with a 48-volt hybrid EQ Boost system, plus a plug-in hybrid based on the 2.0 M 254 motor.

The total output of such an installation will be over 558 hp. (800 N • m) against 476 hp. (650 N • m) / 510 HP (700 N • m) for an eight-cylinder predecessor (C 63 / C 63 S). This will allow the new model to gain a hundred from scratch in 3.5 s versus 4.0 s for the previous sedan C 63 S. And this despite the 250 kg added to the “tseshke” all the hybrid filling based on the 400-volt system. True, from this difference it is necessary to subtract the advantage of the old V8 engine over the turbo four (60 kg). From the bonuses of the new scheme: less static weight on the front axle (“four” instead of V8), and more load on the rear axle (where the electric motor is located). The distribution will be perfect – 50:50.
