Mercedes is ditching the V8 engine in favour of a extremely subtle PHEV system referred to as P3 Hybrid for the brand new Mercedes-AMG C 63 S E Efficiency. We attempt to clarify the way it perform.
The P3 Hybrid system of the mercedes-AMG C 63 S E Efficiency consists of the 2-litre M139l turbo engine and an electrical motor that distributes energy to all 4 wheels by way of a 4Matic+ all-wheel drive system. The electrical motor is positioned on the rear axle and is built-in right into a compact electrical drive unit (CDU) with an electrically operated two-speed gearbox and restricted slip differential.
The electrical motor may distribute energy to the entrance axle if required
The second gear of the transmission engages at round 140 km/h, which corresponds to the electrical motor’s most velocity of 13,500 rpm. Usually, the electrical motor drives the rear axle, but when rear axle slip happens, it’s doable to switch among the electrical motor’s energy to the entrance wheels. The mechanical connection of the absolutely variable all-wheel drive system permits this by way of a propeller shaft and the drive shafts of the entrance wheels. The electrical motor develops 204 HP and 320 Nm which can be found any time by way of the kick-down perform. The continual energy is 70 kW.
Electrically pushed turbocharger
The two-litre thermal engine is derived from the 421 HP engine within the AMG A forty five and is coded M139l the place l signifies that it’s longitudinally mounted whereas within the A forty five it’s transversely mounted. Because of this energy is transmitted to the rear axle by way of a cardan shaft. Then, in case of rear axle slip, the identical propeller shaft used to transmit a part of the electrical motor energy to the entrance wheels additionally transmits a part of the warmth engine energy to the entrance wheels.
The thermal engine develops 476 HP/6725 rpm and 545 Nm/5,250-5,500 rpm. With an influence output of 238 HP/litre, the M139l is the world’s strongest 4-cylinder engine. This was solely made doable by way of an electrically pushed turbocharger which I’ve written about right here earlier than.
The know-how is borrowed from Method 1 and consists of an electrical motor solely 4 cm skinny built-in straight on the turbine shaft between the turbine wheel on the exhaust aspect and the compressor wheel on the consumption aspect. Because of this the turbocharger response is not depending on exhaust fuel circulate, however is managed electrically and so the response is instantaneous at low revs.
The turbocharger motor is powered from the PHEV system’s 400V community and operates as much as 150,000 rpm. The engine has an built-in starter generator (RSG) additionally powered from the 400V community. Energy is transmitted by way of a 9-speed AMG Speedshift MCT 9G computerized transmission by which a moist start-off clutch replaces the traditional torque converter.
The motive force has at his disposal a minimum of 9 applications that regulate not solely the engine, gearbox, steering and suspension response and engine sound but additionally the enhance energy of the electrical motor.
Electrical program: the automobile runs solely on the electrical motor at a high velocity of 125 km/h. However as talked about above, the mechanical connection to the AMG Efficiency 4Matic+ elements signifies that all-wheel drive is offered on this mode too. The 89 kg battery with direct cooling system, positioned above the rear axle, has a capability of 6.1 kWh and may be charged at AC stations with 3.7 kW giving a spread of 13 km.
Consolation program: on this mode, the automobile begins with the electrical motor and the 2 engines run collectively however at low speeds the electrical drive is favoured. The enhance energy of the electrical motor is restricted to a most of 25%.
Battery Maintain program: just like Consolation with the exception that the battery cost degree is stored fixed.
Sport program: the automobile begins with each engines and the enhance energy of the electrical motor goes as much as 65%.
RACE program: Each engines run and the facility enhance of the electrical motor will increase to 80%. Enhance Mode may be accessed from the button on the left arm of the steering wheel.
Slippery program: energy and torque are diminished. Power recuperation (avilable on 4 ranges) and pure electrical propulsion are disabled.
Particular person program: permits particular person setting of assorted parameters.
The Mercedes-AMG C 63 S E Perfromance comes normal with AMG Experience Management with Adaptive damping suspension and integral steering which can also be supplied on the C-Class however the steering angles are totally different: as much as 100 km/h the rear wheels flip in the wrong way to the entrance wheels by 2.5 levels and above 100 km/h they flip in the identical path by as much as 0.7 levels.
