The 150 kW (204 hp) electrical motor is positioned on the rear axle, the place it’s built-in with an electrically shifted two-speed gearbox and the electronically managed limited-slip rear differential in a compact electrical drive unit (EDU)—i.e., a P3 hybrid. The light-weight high-performance battery can be positioned within the rear above the rear axle. This compact design has quite a few benefits:

  • The electrical motor acts immediately on the rear axle and might due to this fact convert its energy extra immediately into propulsion for further increase when transferring off, accelerating or overtaking.

  • The inherent design of the electrical motor implies that its energy can kick in right away at full torque, making significantly agile beginning doable.
    As well as, the driving force instantly experiences a noticeable efficiency improve due to the built-in, electronically managed limited-slip rear differential: the hybrid mannequin accelerates out of bends with nice agility.

  • If slip happens on the rear axle, the drive energy of the electrical motor can be transferred to the entrance wheels as wanted for extra traction. The mechanical connection of the absolutely variable all-wheel drive makes this doable via a propeller shaft and the drive shafts of the entrance wheels.

  • The positioning on the rear axle improves the burden distribution in addition to the axle load distribution within the car and thus types the idea for the convincing dealing with.

  • The AMG idea affords very excessive recuperation effectivity, because the system permits solely minimal mechanical and hydraulic losses from the engine and transmission.

  • The automated two-speed transmission on the rear axle with its specifically calibrated gear ratio ensures the unfold from excessive wheel torque for agile beginning to protected steady output at increased speeds. An electrical actuator engages second gear at round 140 km/h on the newest, which corresponds to the electrical motor’s most pace of round 13,500 rpm.

  • With the rise in efficiency as a result of further electrical motor, the event crew was additionally in a position to enhance the effectivity of your entire car in parallel and obtain decrease emissions in addition to decrease consumption.

The AMG high-performance battery. When the electrification technique was being outlined, it was clear from the outset that every one important parts can be developed in Affalterbach. Amongst these is the AMG high-performance battery (HPB). The event of the lithium-ion power storage system is impressed by applied sciences which have already been confirmed within the Mercedes-AMG Petronas F1 Workforce’s System 1 hybrid racing vehicles.

In the middle of improvement, there was a vigorous change of skilled information between the Excessive Efficiency Powertrains (HPP) System 1 engine store in Brixworth and Mercedes-AMG in Affalterbach. The AMG high-performance battery combines excessive energy that may be known as up incessantly in succession with low weight to extend the general efficiency of the car. Added to this are the quick power draw and the excessive energy density. Which means throughout a brisk drive in hilly terrain, for instance, drivers can instantly name on the total energy potential on uphill stretches, whereas recuperation is robust when driving downhill.

The high-performance battery within the C 63 S E PERFORMANCE affords a capability of 6.1 kWh, steady output of 70 kW and a peak output of 150 kW for ten seconds. The low weight of solely 89 kilograms permits the very excessive energy density of 1.7 kW/kg. For comparability, standard batteries with out direct cooling of the cells obtain about half this determine.

Charging is by way of the three.7 kW on-board AC charger, at a charging station, wallbox or family socket. The battery is designed for quick energy supply and draw, not for the longest doable vary. However, the electrical vary of 13 kilometers permits a sensible working radius, for instance for quiet and emission-free driving from a residential space to the outskirts of the town or to the motorway.

Direct cooling of the battery cells. The idea for the excessive efficiency of the AMG 400-volt battery is its revolutionary direct cooling system. For the primary time, a high-tech coolant primarily based on an electrically non-conductive liquid flows round all 560 cells and cools them individually. Each battery wants an outlined temperature for optimum energy supply. If the battery turns into too chilly or too scorching, it noticeably loses energy at occasions, or must be regulated to keep away from harm if the warmth turns into extreme. The constant temperature of the battery due to this fact has a decisive affect on its efficiency, service life and security.

Typical cooling programs, which solely cool with air or your entire battery pack not directly with water, rapidly attain their limits—particularly as the necessities proceed to extend on account of cells with ever rising power density. If the thermal administration doesn’t fulfil its perform optimally, the battery is prone to ageing prematurely.

For the direct cooling, the AMG specialists needed to develop new cooling modules which might be solely millimeters skinny. Round 14 liters of coolant flow into from prime to backside by means of your entire battery previous every cell with the assistance of a specifically developed high-performance electrical pump, additionally flowing by means of an oil/water warmth exchanger connected on to the battery. This conducts the warmth into one of many car’s two low-temperature (LT) circuits, and from there to the LT radiator on the entrance of the automotive the place it’s launched into the surface air. The system is designed to make sure even warmth distribution within the battery.

The result’s that the battery is at all times inside a constant, optimum working temperature window averaging 45 levels Celsius, regardless of how typically it’s charged or discharged. It might be that the common temperature is exceeded when driving at excessive speeds. The safety mechanisms are due to this fact configured in order that the utmost efficiency might be obtained from the battery, with the temperature stage subsequently lowered by direct cooling.

Typical cooling programs can not address this, and the battery can now not absolutely utilise its potential. That’s not the case with the AMG high-performance battery: even throughout quick laps in hybrid mode on the race monitor, the place acceleration (battery is discharged) and deceleration (battery is charged) are frequent, the power storage system retains its excessive efficiency capability.

Solely efficient direct cooling makes it doable to make use of cells with a really excessive energy density. Because of this particular person answer, the battery system is especially gentle and compact. The low weight can be as a result of material-saving busbar idea, and the light-weight but robust crash construction of the aluminium housing. It ensures the very best stage of security.

Working technique: electrical energy at all times accessible. The essential working technique is derived from the hybrid powerpack of the Mercedes-AMG Petronas System 1 racing automotive. As in motor racing’s premier class, most propulsion is at all times accessible when the driving force calls for it by kickdown—for instance for highly effective acceleration out of bends, or when overtaking. The electrical energy can at all times be known as up and incessantly reproduced by way of excessive recuperation efficiency and needs-based recharging. The automotive’s particular battery idea permits the optimum compromise between most driving dynamics and up to date effectivity. All parts are completely coordinated: the efficiency achieve might be skilled immediately.

Eight AMG drive applications. The eight AMG DYNAMIC SELECT driving modes “Electrical”, “Consolation”, “Battery Maintain”, “Sport”, “Sport+”, “RACE”, “Slippery” and “Particular person” are exactly tailor-made to the brand new drive expertise and thus supply a variety of driving experiences—from environment friendly to dynamic. The driving modes regulate necessary parameters such because the response of the drive system and transmission, the steering traits, the suspension damping or the sound.

The increase energy of the electrical motor additionally is determined by the chosen drive program. It may be chosen by way of the show within the middle console or the AMG steering wheel buttons. Nevertheless, one factor is identical in all applications: the height output of the electrical motor with a lift of 150 kW might be known as up at any time by way of the kick-down perform. The haptic accelerator pedal gives a tangible strain level that the driving force’s foot should overcome.

Often, the Efficiency hybrid begins silently (“Silent Mode”) within the “Consolation” drive program when the electrical motor is switched on. Within the instrument cluster, the “Prepared” icon alerts that the car is able to drive. As well as, a strong, sonorous start-up sound typical of AMG is emitted within the inside by way of the car’s loudspeakers as acoustic suggestions exhibiting readiness to get going. Slight strain on the accelerator pedal is all it takes to set the AMG Efficiency hybrid in movement.

  • “Electrical” drive program: the main target is on the electrical driving expertise. All-electric driving is feasible from standstill as much as 125 km/h, with the combustion engine at all times switched off. The mechanical connection to the AMG Efficiency 4MATIC+ parts implies that all-wheel drive is at all times accessible: if the rear wheels all of the sudden have an excessive amount of slip, the ability of the electrical motor can be transmitted to the entrance wheels by way of the propeller shaft and drive shafts. If the battery has run down or the driving force requests extra energy, the clever working management system routinely switches to the “Consolation” driving mode and the combustion engine begins as much as present propulsion.

  • “Consolation” drive program:beginning off is undertaken usually in electrical mode. Combustion engine and electrical motor run because the state of affairs calls for—with electrical drive at low speeds, for instance in residential areas or within the metropolis middle, and hybrid driving with combustion engine and electrical motor within the countryside and on the motorway. The increase energy of the electrical motor is a most of round 25%. General, the result’s a harmonious and consumption-optimized driving impression, due partly to the early upshifts of the AMG SPEEDSHIFT MCT-9G transmission. Suspension and steering are arrange for an emphasis on consolation. The steering focus is on power effectivity, in order that gasoline consumption and emissions might be lowered. The hallmark AMG sportiness and agility are retained.

  • “Battery Maintain” drive program: as within the “Consolation” drive program, the combustion engine and electrical motor run primarily based on the state of affairs with a most increase of round 25%. The largest distinction is that the working technique retains the battery state of cost fixed. For instance, if the battery is at 75% cost, it stays on this vary in “Battery Maintain”. Use of the electrical motor is then restricted and optimized for low energy consumption, which is compensated for by recuperation, for instance. Benefit for drivers: they’ll resolve when to make full use of the battery cost once more, just by altering the drive program.

  • “Sport” drive program: beginning off with combustion engine and electrical motor and situational interplay of the 2 drives. Extra increase from the electrical motor is enabled, as much as round 65%. Sporty driving impression owing to extra agile accelerator response, shorter shift occasions and earlier downshifts. A extra dynamic suspension and steering set-up.

  • “Sport+” drive program: beginning off with combustion engine and electrical motor and situational interplay of the 2 drives. Even increased increase efficiency of as much as 80%. Extraordinarily sporty character due to much more agile throttle response and focused torque intervention throughout upshifts with cylinder deactivation for optimum shift occasions. Elevated idle pace for sooner beginning. An much more dynamic set-up for suspension, steering and powertrain.

  • “RACE” drive program: for extremely dynamic driving on closed race tracks. On this mode, all of the parameters are configured for max efficiency. Beginning off with combustion engine and electrical motor and situational interplay of the 2 drives. Electrical increase energy of the electrical motor as much as 80%. Sturdy battery recharging at low energy demand for max electrical availability. As well as, the “Enhance Mode” might be known as up by way of the left-hand steering wheel button. The increase energy is then restricted to a most of 30% in an effort to preserve power reserves. These can then be used particularly on the race monitor for spontaneous energy demand by way of kick-down and 100% increase energy—or instance for an acceleration manoeuvre or highly effective acceleration out of corners.

  • “Slippery” drive program: optimized for slippery highway circumstances, with lowered energy and a flat torque curve. Electrical-only driving and recuperation adjustment are deactivated.

  • “Particular person” drive program: particular person customisation of the drive, transmission, AMG DYNAMICS, suspension, steering and exhaust system.

Efficiency hybrid drive can management the traction of 1 wheel as a substitute of ESP. The hybrid drive additionally brings advantages by way of the dynamic dealing with management. As a substitute of braking intervention by ESP, the electrical motor can even management traction as quickly as a wheel alerts an excessive amount of slip. To do that, the clever management system reduces the drive torque of the electrical motor that’s transferred to the wheel by way of the limited-slip rear differential. The result’s that ESP doesn’t must intervene in any respect, or solely later. The combustion engine can thus be operated with increased torque, which each improves agility afterwards and will increase effectivity. As well as, the ability in any other case “destroyed” throughout braking can be utilized to cost the battery.

Recuperation selectable in 4 levels. As a result of the high-performance battery is at all times within the optimum temperature window of round 45 levels on account of direct cooling, regeneration will also be optimized—usually a battery heats up strongly at excessive regeneration energy, in order that power restoration must be restricted.

Recuperation begins when the driving force takes their foot off the accelerator pedal, i.e. in overrun mode with out touching the brake pedal. This expenses the battery and creates a powerful braking torque—the wheel brakes are subjected to much less put on or, relying on the regeneration stage and visitors state of affairs, do not need to be utilized in any respect. One other benefit of recuperation: the car doesn’t pace up on steep downhill slopes. So the system works like an engine brake, but additionally feeds power into the battery.

The motive force can choose 4 totally different regeneration ranges utilizing the right-hand AMG steering wheel button. This is applicable in all drive applications except for “Slippery”, and the power restoration is configured in another way relying on the driving mode.

  • Stage 0: The car behaves equally to a standard combustion-engine mannequin with handbook transmission, the place the clutch is disengaged, and rolls on with the least resistance when the accelerator is launched. The recuperation stage may be very low, and solely serves to take care of the car’s energy provide. With the combustion engine switched off, friction losses within the powertrain are lowered to a minimal.

  • Stage 1: That is the usual setting, at which recuperation is already noticeable to the driving force, and corresponds roughly to the deceleration of a standard combustion engine when the clutch is engaged.

  • Stage 2: Stronger recuperation, the brake pedal hardly must be used when transferring in visitors.

  • Stage 3: Most power restoration, making so-called “one-pedal” driving doable as in an all-electric automotive. Relying on the driving standing, greater than 100 kW of energy might be fed again into the battery.

  • Particular characteristic of the RACE drive program: on the racetrack, the driving force needs to squeeze the utmost time doable out of any braking motion. Within the “RACE” drive program, recuperation is routinely set at stage 1 to permit essentially the most reproducible car conduct doable on the limits.

AMG 2.0-liter engine with electrically assisted exhaust gasoline turbocharger. The AMG 2.0-liter four-cylinder engine was developed completely on the firm’s headquarters in Affalterbach. The internally named M139l engine (l for longitudinal set up) is the world’s first series-production engine to be turbocharged with an electrical exhaust gasoline turbocharger. This revolutionary system is derived immediately from the expertise that the Mercedes-AMG Petronas F1 Workforce has been utilizing so efficiently within the premier class of motorsport for a few years.

The brand new type of turbocharging ensures significantly spontaneous response throughout your entire rev vary. This results in an much more dynamic driving expertise, whereas on the identical time rising effectivity. In comparison with its C 43 4MATIC and SL 43 siblings, nevertheless, the turbocharger within the C 63 S is considerably bigger. This allows the next airflow charge and thus extra energy. As well as, the built-in electrical motor is powered by the 400-volt high-voltage system (48 volts within the 43 fashions).

The useful precept of the electrical exhaust gasoline turbocharger. An electrical motor round 4 centimeters skinny is built-in immediately on the turbocharger shaft between the turbine wheel on the exhaust facet and the compressor wheel on the consumption facet. Electronically managed, this drives the shaft of the turbocharger immediately and thus accelerates the compressor wheel, earlier than the exhaust gasoline move takes over the drive within the standard manner.

This considerably improves the response immediately from idle pace and throughout your entire rev vary. The combustion engine responds much more spontaneously to accelerator pedal enter, whereas your entire driving really feel is considerably extra dynamic. As well as, the electrification of the turbocharger permits increased torque at low revs. This additionally will increase agility and optimises acceleration from a standstill. Even when the driving force takes their foot off the accelerator or brakes, the expertise is ready to keep increase strain always. This ensures a constantly direct response.

Powered by the 400-volt on-board electrical system, the electrical exhaust gasoline turbocharger operates at speeds of as much as 150,000 rpm. The turbocharger, electrical motor and energy electronics are linked to the cooling circuit of the combustion engine in an effort to guarantee an thought temperature surroundings always.

The closed-deck design of the M139—a motorsport design—ensures excessive rigidity at the side of low weight and permits peak combustion pressures of as much as 160 bar. The areas across the cylinders are largely stable, and the duvet plate is penetrated solely by smaller ducts for the coolant and engine oil. One other excellent characteristic is the two-stage petrol injection. Within the first stage, significantly quick and exact piezo injectors ship the gasoline into the combustion chambers at pressures of as much as 200 bar. The second stage provides consumption manifold duct injection with solenoid valves, which is required to attain the engine’s excessive particular energy output.

The excessive output additionally necessitates a complicated cooling system that may cool the cylinder head and crankcase to totally different temperature ranges. This measure makes it doable to take care of a chilly cylinder head for max energy with environment friendly ignition timing, together with a heat crankcase to cut back inner engine friction. The cylinder head is cooled by a mechanical high-performance water pump; the crankcase is cooled by a second, electrically pushed water pump. After a chilly begin, this pump stays passive till the engine has warmed up. In operation it’s regulated by the engine management unit in order that the crankcase is at all times cooled in keeping with want.

Essentially the most highly effective manufacturing four-cylinder. Within the C 63 S, the four-cylinder unit develops 350 kW (476 hp) at 6725 rpm. This makes it the world’s strongest series-production four-cylinder engine. The utmost torque of 545 N·m is on the market at 5250‑5500 rpm. A belt-driven starter generator (RSG) combines an alternator and starter in a single part. The RSG begins the combustion engine and ensures the essential provide of the ancillary parts equivalent to air con or driving lights. This additionally applies when the car is at a visitors gentle and the cost stage of the high-voltage battery is now not enough to help the low-voltage on-board electrical system. The RSG is built-in into the 400-volt high-voltage community.

Energy is transmitted by way of the AMG SPEEDSHIFT MCT 9G transmission (MCT = Multi-Clutch Transmission), during which a moist start-off clutch replaces the torque converter. It reduces weight and, due to its decrease inertia, optimises response to accelerator pedal enter, particularly throughout spurts and cargo modifications. The elaborately calibrated software program ensures extraordinarily quick shift occasions in addition to quick a number of downshifts if required. As well as, the intermediate throttle perform within the “Sport” and “Sport+” driving modes delivers a very emotionally interesting gearshift expertise. There’s additionally the RACE START perform, which ensures optimum acceleration from a standstill.

AMG RIDE CONTROL suspension with Adaptive Damping System. The usual AMG RIDE CONTROL steel-spring suspension with Adaptive Damping System combines pronounced sporty dynamic dealing with with the consolation over lengthy distances that’s such a trademark of the model. The idea for that is offered by the entrance axle, with specifically developed steering knuckles and suspension joints on the spring management arm, and by the rear axle, which additionally options elastokinematics designed for driving dynamics.

Based mostly on this, the damping at every particular person wheel is constantly adjusted to the present demand—at all times taking into consideration the preselected suspension stage, the driving fashion and the situation of the highway floor. Along with an enchancment in experience high quality and luxury, this leads, above all, to a rise in driving security. The system used has already proved its value in GT3 buyer sport and within the AMG GT Black Collection.

The important thing parts are dampers manufactured from light-weight supplies that may transfer considerably extra hydraulic fluid than standard programs: as a substitute of a slim piston, a considerably bigger disc displaces the oil within the damper. Every damper is fitted with two exterior electrohydraulic valves, which act independently of one another to regulate draw and strain. Within the course of, the system’s management software program constantly screens working knowledge equivalent to steering wheel angle, car pace, acceleration and physique motion. On this manner, the dampers are managed inside milliseconds because the state of affairs requires. The result’s that, even throughout excessive driving maneuvers or on poor roads, the wheels are at all times firmly on the bottom. There’s a selection of three totally different damping maps (“Consolation”, “Sport” and “Sport+”).

Three-stage AMG parameter steering and normal rear-axle steering. The steering structure additionally contributes to the rise in dynamics and luxury. The three-stage AMG parameter steering system, for instance, encompasses a variable steering geometry ratio that adapts to the chosen drive program. At excessive speeds, the steering energy help decreases; at low speeds it’s steadily elevated. Because of this, comparatively little steering effort is required at low speeds, in addition to when maneuvering and parking, whereas the absolute best management over the car is maintained when driving sooner. Within the “Sport” and “Sport+” suspension settings, the driving force additionally experiences considerably extra suggestions concerning the driving situation by way of the steering wheel.

The usual rear axle steering operates with a most steering angle of two.5 levels. Up thus far, the rear wheels flip in the other way to the entrance wheels at speeds of as much as 100 km/h (variable relying on the AMG DYNAMICS setting). This results in a digital shortening of the wheelbase, which in flip leads to considerably extra agile turn-in, much less steering effort and improved maneuverability.

For instance, the turning circle is noticeably lowered when turning or parking. At speeds above 100 km/h (variable relying on the AMG DYNAMICS setting), alternatively, the rear wheels flip in parallel to the entrance wheels—as much as a most of 0.7 levels. This digital extension of the wheelbase has a optimistic impact on driving stability, results in a sooner build-up of lateral power when altering course and thus to a extra direct response of the car to steering instructions. The response of the rear-axle steering is determined by the chosen AMG DYNAMIC SELECT drive program.

The built-in AMG DYNAMICS dynamic management system can be a part of the usual specification. It influences the management methods of ESP (Digital Stability Program), the all-wheel drive, and the electronically managed limited-slip rear differential. This will increase agility with out compromising the car’s stability.

AMG DYNAMICS determines how the car ought to react. The system makes use of the accessible sensors, amongst different issues, to establish the pace, lateral acceleration, steering angle and yaw charge. On account of an clever pilot-control precept, it’s doable to anticipate how the driving force needs the car to behave, primarily based on the driving force’s actions and on knowledge from the sensors. Regulation is tailor-made to the dynamic driving competence of the driving force with none noticeable or disruptive interventions by the system. The motive force will get a really genuine driving really feel with excessive cornering dynamics and optimum traction, in addition to excessive stability and predictable dealing with. Even skilled drivers obtain optimum help with out feeling patronised by the system.

  • AMG DYNAMICS “Primary” is assigned to the “Consolation” and “Electrical” drive program. The design leads to a really steady experience with excessive yaw damping.

  • “Superior” is activated within the “Sport” program. The car stays neutrally balanced. The lowered yaw damping and elevated agility help dynamic manoeuvres equivalent to driving on winding nation roads.

  • “Professional” (abbreviation for “Skilled”) is a part of the “Sport+” program. In “Professional” the driving force receives much more help for dynamic driving maneuvers, whereas agility and suggestions from the highway when cornering are additional enhanced.

  • “Grasp” is coupled with the drive program “RACE”. The “Grasp” mode is aimed toward drivers who need to expertise dynamism and driving enjoyment on cordoned-off circuits. “Grasp” affords a barely oversteering car steadiness, extra direct steering and extra agile turn-in conduct. On this manner, “Grasp” ensures most agility and optimally exploits the dynamic potential of the “S” model. To activate “Grasp” mode, the driving force should use the separate button within the middle console to change ESP to ESP SPORT dealing with mode or ESP OFF.

  • Within the “Particular person” drive program, drivers can set the AMG DYNAMICS ranges “Primary”, “Superior”, “Professional” and “Grasp” themselves.
