A two-speed electrical motor positioned on the rear axle helps the two.0-liter turbo engine that’s mounted longitudinally on the entrance; that is essentially the most highly effective manufacturing four-cylinder on this planet.
Energy supply and torque build-up happen very spontaneously and at once: as in Method 1, the electrical help of the exhaust fuel turbocharger eliminates the turbo lag of the combustion engine, whereas on the similar time the electrical drive pushes powerfully from a standstill.
The electrical powertrain and the high-performance battery with 400 volts are AMG-exclusive, in-house developments. They underline the high-end engineering competence of the Affalterbach-based builders. Similar to in Method 1, the battery is particularly designed for quick energy output and draw with modern direct cooling of the cells. The mixed system output is 500 kW (680 hp), the mixed most system torque 1020 N·m. These are new peak values for the C-Class.
Additionally as in Method 1, the battery is particularly designed for quick energy supply and take-up. The electrical-only vary supported by the 6.1 kWh battery is 13 kilometers (8 miles).
Different highlights of the brand new mannequin collection, which is being launched concurrently as a sedan and as anwagon: for the primary time in a C 63, the totally variable all-wheel drive system AMG Efficiency 4MATIC+ is used to switch the drive energy to the street, and features a Drift Mode for much more driving pleasure. Added to that is lively rear axle steering as normal, one other distinctive characteristic on this section.
The AMG-specific E PERFORMANCE hybrid drive. Within the new Mercedes-AMG C 63 S E PERFORMANCE, the two.0-liter four-cylinder turbo engine is mixed with a completely excited synchronous electrical motor, a high-performance battery developed in Affalterbach and totally variable AMG Efficiency 4MATIC+ all-wheel drive. The system output of 500 kW (680 hp) and the utmost system torque of 1020 N·m ship spectacular efficiency: each fashions speed up from a standstill to 100 km/h in 3.4 seconds. Acceleration solely ends at an electronically ruled 280 km/h (Wagon 270 km/h, in each circumstances with optionally available AMG Driver’s Bundle).
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 instantly on the rear axle and may subsequently convert its energy extra instantly into propulsion for further enhance when shifting off, accelerating or overtaking.
The inherent design of the electrical motor signifies that its energy can kick in right away at full torque, making significantly agile beginning attainable.
As well as, the driving force instantly experiences a noticeable efficiency enhance 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 totally variable all-wheel drive makes this attainable via a propeller shaft and the drive shafts of the entrance wheels.
The positioning on the rear axle improves the load distribution in addition to the axle load distribution within the automobile and thus kinds the idea for the convincing dealing with.
The AMG idea provides 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 secure steady output at larger 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 group was additionally in a position to enhance the effectivity of all the automobile 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 elements 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 Group’s Method 1 hybrid racing vehicles.
In the middle of growth, there was a energetic change of knowledgeable data between the Excessive Efficiency Powertrains (HPP) Method 1 engine store in Brixworth and Mercedes-AMG in Affalterbach. The AMG high-performance battery combines excessive energy that may be known as up regularly in succession with low weight to extend the general efficiency of the automobile. 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 complete energy potential on uphill stretches, whereas recuperation is powerful when driving downhill.
The high-performance battery within the C 63 S E PERFORMANCE provides 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 through 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 attainable 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 modern direct cooling system. For the primary time, a high-tech coolant based mostly 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 injury if the warmth turns into extreme. The constant temperature of the battery subsequently has a decisive affect on its efficiency, service life and security.
Typical cooling programs, which solely cool with air or all the battery pack not directly with water, shortly attain their limits—particularly as the necessities proceed to extend resulting from cells with ever growing power density. If the thermal administration doesn’t fulfil its operate optimally, the battery is liable to ageing prematurely.
For the direct cooling, the AMG specialists needed to develop new cooling modules which can be solely millimeters skinny. Round 14 liters of coolant flow into from prime to backside by means of all the 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 hooked up on to the battery. This conducts the warmth into one of many automobile’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 all the time inside a constant, optimum working temperature window averaging 45 levels Celsius, irrespective of how usually it’s charged or discharged. It might be that the common temperature is exceeded when driving at excessive speeds. The safety mechanisms are subsequently configured in order that the utmost efficiency might be obtained from the battery, with the temperature degree subsequently lowered by direct cooling.
Typical cooling programs can’t address this, and the battery can not totally utilise its potential. That’s not the case with the AMG high-performance battery: even throughout quick laps in hybrid mode on the race observe, 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 attainable to make use of cells with a really excessive energy density. Due to this particular person resolution, the battery system is especially mild and compact. The low weight can be as a result of material-saving busbar idea, and the light-weight but sturdy crash construction of the aluminium housing. It ensures the best degree of security.
Working technique: electrical energy all the time out there. The essential working technique is derived from the hybrid powerpack of the Mercedes-AMG Petronas Method 1 racing automotive. As in motor racing’s premier class, most propulsion is all the time out there 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 all the time be known as up and regularly reproduced through 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 elements are completely coordinated: the efficiency achieve might be skilled instantly.
Eight AMG drive packages. 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 modify necessary parameters such because the response of the drive system and transmission, the steering traits, the suspension damping or the sound.
The enhance energy of the electrical motor additionally is dependent upon the chosen drive program. It may be chosen through the show within the heart console or the AMG steering wheel buttons. Nevertheless, one factor is similar in all packages: the height output of the electrical motor with a lift of 150 kW might be known as up at any time through the kick-down operate. The haptic accelerator pedal gives a tangible stress level that the driving force’s foot should overcome.
Normally, 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 automobile is able to drive. As well as, a robust, sonorous start-up sound typical of AMG is emitted within the inside through the automobile’s loudspeakers as acoustic suggestions displaying readiness to get going. Slight stress on the accelerator pedal is all it takes to set the AMG Efficiency hybrid in movement.
“Electrical” drive program: the main focus is on the electrical driving expertise. All-electric driving is feasible from standstill as much as 125 km/h, with the combustion engine all the time switched off. The mechanical connection to the AMG Efficiency 4MATIC+ elements signifies that all-wheel drive is all the time out there: if the rear wheels instantly have an excessive amount of slip, the facility of the electrical motor can be transmitted to the entrance wheels through the propeller shaft and drive shafts. If the battery has run down or the driving force requests extra energy, the clever working management system robotically switches to the “Consolation” driving mode and the combustion engine begins as much as present propulsion.
“Consolation” drive program:beginning off is undertaken generally 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 heart, and hybrid driving with combustion engine and electrical motor within the countryside and on the motorway. The enhance energy of the electrical motor is a most of round 25%. Total, the result’s a harmonious and consumption-optimized driving impression, due partially 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 decreased. 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 based mostly on the state of affairs with a most enhance 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 will 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 enhance 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 larger enhance 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 enhance energy of the electrical motor as much as 80%. Sturdy battery recharging at low energy demand for max electrical availability. As well as, the “Increase Mode” might be known as up through the left-hand steering wheel button. The enhance energy is then restricted to a most of 30% with the intention to preserve power reserves. These can then be used particularly on the race observe for spontaneous energy demand through kick-down and 100% enhance energy—or instance for an acceleration manoeuvre or highly effective acceleration out of corners.
“Slippery” drive program: optimized for slippery street circumstances, with decreased 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 when it comes to the dynamic dealing with management. As an alternative of braking intervention by ESP, the electrical motor may also 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 through the limited-slip rear differential. The result’s that ESP doesn’t need to intervene in any respect, or solely later. The combustion engine can thus be operated with larger torque, which each improves agility afterwards and will increase effectivity. As well as, the facility 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 all the time within the optimum temperature window of round 45 levels resulting from direct cooling, regeneration may 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 robust braking torque—the wheel brakes are subjected to much less put on or, relying on the regeneration degree and site visitors state of affairs, shouldn’t have to be utilized in any respect. One other benefit of recuperation: the automobile doesn’t pace up on steep downhill slopes. So the system works like an engine brake, but in addition feeds power into the battery.
The motive force can choose 4 completely different regeneration ranges utilizing the right-hand AMG steering wheel button. This is applicable in all drive packages except for “Slippery”, and the power restoration is configured otherwise relying on the driving mode.
Stage 0: The automobile 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 degree may be very low, and solely serves to keep up the automobile’s energy provide. With the combustion engine switched off, friction losses within the powertrain are decreased 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 shifting in site visitors.
Stage 3: Most power restoration, making so-called “one-pedal” driving attainable 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 desires to squeeze the utmost time attainable out of any braking motion. Within the “RACE” drive program, recuperation is robotically set at degree 1 to permit essentially the most reproducible automobile conduct attainable on the limits.
AMG 2.0-liter engine with electrically assisted exhaust fuel turbocharger. The AMG 2.0-liter four-cylinder engine was developed totally 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 fuel turbocharger. This modern system is derived instantly from the expertise that the Mercedes-AMG Petronas F1 Group 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 all the rev vary. This results in an much more dynamic driving expertise, whereas on the similar time growing effectivity. In comparison with its C 43 4MATIC and SL 43 siblings, nevertheless, the turbocharger within the C 63 S is considerably bigger. This permits a better airflow price 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 purposeful precept of the electrical exhaust fuel turbocharger. An electrical motor round 4 centimeters skinny is built-in instantly on the turbocharger shaft between the turbine wheel on the exhaust aspect and the compressor wheel on the consumption aspect. Electronically managed, this drives the shaft of the turbocharger instantly and thus accelerates the compressor wheel, earlier than the exhaust fuel movement takes over the drive within the standard method.
This considerably improves the response instantly from idle pace and throughout all the rev vary. The combustion engine responds much more spontaneously to accelerator pedal enter, whereas all the driving really feel is considerably extra dynamic. As well as, the electrification of the turbocharger permits larger 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 enhance stress always. This ensures a constantly direct response.
Powered by the 400-volt on-board electrical system, the electrical exhaust fuel 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 with the intention to guarantee an concept temperature setting always.
The closed-deck design of the M139—a motorsport design—ensures excessive rigidity along with low weight and permits peak combustion pressures of as much as 160 bar. The areas across the cylinders are principally stable, and the quilt 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 classy cooling system that may cool the cylinder head and crankcase to completely different temperature ranges. This measure makes it attainable to keep up a chilly cylinder head for max energy with environment friendly ignition timing, together with a heat crankcase to cut back inside 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 all the time cooled in line with want.
Probably 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 accessible at 5250‑5500 rpm. A belt-driven starter generator (RSG) combines an alternator and starter in a single element. The RSG begins the combustion engine and ensures the essential provide of the ancillary elements comparable to air-con or driving lights. This additionally applies when the automobile is at a site visitors mild and the cost degree of the high-voltage battery is not adequate to help the low-voltage on-board electrical system. The RSG is built-in into the 400-volt high-voltage community.
Energy is transmitted through 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 brief shift occasions in addition to quick a number of downshifts if required. As well as, the intermediate throttle operate within the “Sport” and “Sport+” driving modes delivers a very emotionally interesting gearshift expertise. There may be additionally the RACE START operate, 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 an indicator of the model. The idea for that is supplied 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.
Primarily based on this, the damping at every particular person wheel is constantly adjusted to the present demand—all the time bearing in mind the preselected suspension degree, the driving type and the situation of the street floor. Along with an enchancment in trip high quality and luxury, this leads, above all, to a rise in driving security. The system used has already proved its price in GT3 buyer sport and within the AMG GT Black Sequence.
The important thing elements are dampers made 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 manage draw and stress. Within the course of, the system’s management software program constantly displays working knowledge comparable to steering wheel angle, automobile pace, acceleration and physique motion. On this method, 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 all the time firmly on the bottom. There’s a alternative of three completely different damping maps (“Consolation”, “Sport” and “Sport+”).
Three-stage AMG parameter steering and normal rear-axle steering. The steering format additionally contributes to the rise in dynamics and luxury. The three-stage AMG parameter steering system, for instance, contains 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 very best management over the automobile is maintained when driving sooner. Within the “Sport” and “Sport+” suspension settings, the driving force additionally experiences considerably extra suggestions concerning the driving situation through the steering wheel.
The usual rear axle steering operates with a most steering angle of two.5 levels. Up so far, the rear wheels flip in the wrong 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 ends in considerably extra agile turn-in, much less steering effort and improved maneuverability.
For instance, the turning circle is noticeably decreased when turning or parking. At speeds above 100 km/h (variable relying on the AMG DYNAMICS setting), then again, 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 pressure when altering path and thus to a extra direct response of the automobile to steering instructions. The response of the rear-axle steering is dependent upon 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 automobile’s stability.
AMG DYNAMICS determines how the automobile ought to react. The system makes use of the out there sensors, amongst different issues, to establish the pace, lateral acceleration, steering angle and yaw price. Attributable to an clever pilot-control precept, it’s attainable to anticipate how the driving force desires the automobile to behave, based mostly 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.
