TWO PERFORMING HYBRIDS – The future sports of the Mercedes-AMG will be electrified thanks to two different ones sistemi ibridi plug-in. Both couple a combustion engine to an electric one and are called by the German company e-Performance: one is based on the 4.0 V8 twin-turbo, the other on the 4-cylinder 2.0-liter turbo of the A45. Both use the nine-speed Mercedes-AMG Speedshift MCT gearbox with torque converter.

A MOTOR ON THE REAR AXLE – The new plug-in hybrids from Mercedes-AMG are based on a new scheme where the heat engine is positioned at the front and that electric at the rear. The electric unit will have an output of up to 204 hp and is powered by a high-performance battery (located above the rear axle), and is totally independent. In addition, the electric motor has a two-speed gearbox it is integrated into the torque vectoring self-locking differential, which transfers torque optimally to the two wheels according to the driving situation. In difficult conditions, should the slip on the rear axle increase, the power of the electric motor is also transferred to the front wheels for a short period of time: this is made possible by the mechanical connection of the four-wheel drive through the cardan shaft and the shafts transmission of the front wheels.

BATTERY – Both the electric motor and the battery have been developed in-house. In particular, the latter can count on a400 volt architecture and on a direct cooling system. The 560 cells that make up the accumulator are individually cooled, being permanently surrounded by 14 liters of coolant which is circulated by an electric pump. The system is designed to ensure uniform distribution and a constant temperature of the battery temperature at 45 ° C (a value considered optimal to ensure maximum performance and reliability). The battery is 6.1 kWh, weighs 89 kg and has a peak power of 200 horsepower.

THE HYBRID WITH THE V8 – The most powerful plug-in hybrid, delivering up to 804hp overall, with 1,000Nm of torque, combines the current 4-liter twin-turbo V8 to an electric unit and should debut with the GT73e 4Matic 4 doors. Performance is like a true hypercar: 0-100 in less than 3 seconds. The other specifications will be made available at a later date.

THE HYBRID WITH 4 CYLINDERS – The other hybrid matches an updated version of the 2.0 turbo 4-cylinder Mercedes-AMG (internally called M139, is currently used on the A45 S) with an electric motor, for a total power of 503 hp. The real novelty is the electric turbocharger, a technology derived from the world of F1 that is implemented for the first time in a production vehicle, and which should allow the turbo lag to be eliminated. THE ELECTRIC TURBO – It works like this: an electric motor less than four centimeters wide is integrated directly on the turbocharger shaft, between the turbine wheel on the exhaust gas side and the compressor wheel on the fresh air side. Electronically controlled, the small electric motor directly drives the turbocharger shaft thereby accelerating the compressor wheel before the exhaust gas stream takes over. The turbocharger is powered by the 400 volt onboard power supply reaching up to 156,000 rpm. The four-cylinder hybrid system will debut on the future C63e 4Matic available early 2022.

DRIVING PROGRAMS – There will be six driving programs that the user can select from the classic Mercedes-AMG Dynamic Select: “Electric”, “Comfort”, “Sport”, “Sport +”, “Race”. The driving programs adjust important parameters such as throttle and shift response, steering consistency, chassis damping and exhaust noise. Starting the car will always be “green” since Comfort mode will always be engaged in Silent Mode, which uses only the electric motor. Mercedes-AMG Performance hybrids can also count on the integrated control system of the vehicle dynamics Mercedes-AMG Dynamics, which using the various sensors, acts on the ESP (Electronic Stability Program), all-wheel drive and electronically controlled differential lock of the rear axle. This system “anticipates” the behavior of the vehicle based on the actions of the driver and the data obtained from the sensors.

THE ELECTRIC AMG – The first Mercedes-AMG models powered by the electric motor alone will be based on the Mercedes EQ models engineered on the EVA platform. The Affalterbach house will make changes to the chassis, brakes, exterior design, interior design, equipment and options. These performance variants are defined with the initials Mercedes-AMG 43 and 53. The first to arrive will be one AMG version of the EQS, premium sedan that will be unveiled on April 15th.
