“With its performance hybrid drive and electrically assisted exhaust turbocharger, the new C 63 S E PERFORMANCE is a technological masterpiece that takes a new approach. The electrified powertrain offers a whole new driving experience. The immediate response of the electric drive at the rear axle, the rapid torque build-up as well as the fast power output and also draw of our battery are very special features. Add to this the standard-fit rear axle steering and the fully variable all-wheel drive with Drift Mode – the new C 63 once again illustrates the high level of technical expertise that AMG possesses”, says Jochen Hermann, Member of Executive Board – Chief Technical Officer of Mercedes-AMG GmbH. 

Expressive design with highly effective proportions and hanging particulars

Form follows operate: the design of the new C 63 S differs from the Mercedes-Benz C-Class in its extra muscular proportions. The entrance finish is 50 millimetres longer and the entrance wings are wider. In phrases of size, the Saloon measures an additional 83 millimetres. The wider monitor width on the entrance axle leads to 76 millimetres extra total width on the entrance. And the wheelbase has grown by 10 millimetres. 

A new distinguishing characteristic, and one that’s unique to the C 63 S, is the slim air outlet within the centre of the bonnet that transitions elegantly into the 2 powerdomes. A small however notably advantageous element: for the primary time ever on a Mercedes-AMG manufacturing mannequin, a spherical badge with a black AMG emblem replaces the Mercedes star with laurel wreath on the bonnet. Further typical parts embrace the AMG-specific radiator grille with vertical struts and the AMG entrance apron in jet-wing design. Two electronically managed AIR PANELS (behind the radiator grille and within the entrance apron) enable the air to be regulated as required. 

Matching aspect skirts, the rear apron with giant diffuser in addition to the 2 trapezoidal, externally ribbed twin tailpipe trims spherical off the design. Exclusive particulars on the rear embrace the particular airflow breakaway edge on the boot lid (roof spoiler on the Estate), the plug-in charging flap and the mannequin designation set towards a crimson background. The C 63 S rolls on 19-inch AMG light-alloy wheels and combined tyres as customary. Optional 20-inch wheel/tyre combos, additionally with combined tyres, can be found, together with one new set of cast wheels.

The AMG particular E PERFORMANCE hybrid drive

Combustion engine within the entrance, electrical motor within the rear 

In the new Mercedes-AMG C 63 S E PERFORMANCE, the two.0-litre four-cylinder turbo engine is mixed with a completely excited synchronous electrical motor, a high-performance battery developed in Affalterbach and totally variable AMG Performance 4MATIC+ all-wheel drive. The system output of 500 kW and the utmost system torque of 1020 Nm allow spectacular driving efficiency: the Saloon accelerates from a standstill to 100 km/h in 3.4 seconds. Acceleration solely ends at an electronically ruled 280 km/h. 

The 150 kW 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). Experts confer with this structure as a P3 hybrid. The light-weight high-performance battery can also be positioned within the rear above the rear axle. 

This compact design has quite a few benefits: 

• The electrical motor acts straight on the rear axle and may subsequently convert its energy extra straight into propulsion – for that further enhance when shifting off, accelerating or overtaking.
• The inherent design of the electrical motor implies that its energy can kick in right away at full torque, making notably agile beginning potential.
• In addition, the driving force instantly experiences a noticeable efficiency enhance due to the built-in, electronically managed limited-slip rear differential: The hybrid mannequin is extremely agile when accelerating out of corners, provides optimum traction and subsequently additionally a excessive stage of driving security.
• If slip happens on the rear axle, the drive energy of the electrical motor can also be transferred to the entrance wheels as wanted for extra traction. The mechanical connection of the totally variable all-wheel drive makes this potential by means of 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 types the premise 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 protected steady output at greater speeds. An electrical actuator engages second gear at round 140 km/h on the newest, which corresponds to the electrical motor’s most velocity of round 13,500 rpm. 

Inspired by Formula 1, developed in Affalterbach

When the electrification technique was being outlined, it was clear from the outset that each one important parts could be developed in Affalterbach. At the guts of that is the AMG high-performance battery (HPB). The growth of the lithium-ion power storage system is impressed by applied sciences which have already been confirmed within the Mercedes-AMG Petronas F1 Team’s Formula 1 hybrid racing automobiles. The AMG high-performance battery combines excessive energy that may be known as up ceaselessly 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. 

70 kW steady output and 150 kW peak output

The high-performance battery provides a capability of 6.1 kWh, a steady output of 70 kW and a peak output of 150 kW for 10 seconds. The low weight of solely 89 kilograms helps to ship the very excessive energy density of 1.7 kW/kg. Charging takes place through the put in 3.7 kW on-board charger with alternating present at a charging station, wallbox or family socket. The battery is designed for quick energy supply and draw, not for the longest potential vary. Nevertheless, the electrical vary of 13 kilometres permits a sensible working radius, for instance for quiet and emission-free driving from a residential space to the outskirts of town or to the motorway.

The continuous push for innovation: direct cooling of the battery cells

Every battery wants a outlined temperature for optimum energy supply. The foundation for the excessive efficiency of the AMG 400-volt battery is its revolutionary direct cooling system: a high-tech coolant flows round all 560 cells and cools them individually. The result’s that the battery is at all times in a constant, optimum working temperature window, irrespective of how typically it’s charged or discharged. It might be that the typical temperature is exceeded when driving at excessive speeds. The safety mechanisms are subsequently configured in order that the utmost efficiency could be obtained from the battery, with the temperature stage subsequently lowered by direct cooling. 

Operating technique: electrical energy at all times obtainable

The primary working technique is derived from the hybrid powerpack of the Mercedes-AMG Petronas Formula 1 racing automotive. As within the premier class of motor sport, most energy is at all times obtainable when the driving force calls it up by kick-down – for instance, to speed up powerfully out of bends or when overtaking. The electrical energy can at all times be known as up and ceaselessly reproduced through excessive recuperation efficiency and needs-based recharging. 

Eight AMG drive applications 

The eight AMG DYNAMIC SELECT drive applications “Electric”, “Comfort”, “Battery Hold”, “Sport”, “Sport+”, “RACE”, “Slippery” and “Individual” are exactly tailor-made to the new drive expertise and thus supply a wide selection of driving experiences – from environment friendly to dynamic. The drive applications alter vital 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 will depend on the chosen drive program. The peak output of the electrical motor with a enhance of 150 kW could be known as up at any time through the kick-down operate. 

• “Electric” 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 at all times switched off. The mechanical connection to the AMG Performance 4MATIC+ parts implies that all-wheel drive is at all times obtainable: if the rear wheels out of the blue have an excessive amount of slip, the facility of the electrical motor can also 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 mechanically switches to the “Comfort” drive program and the combustion engine begins as much as present propulsion. 
• “Comfort” drive program: Starting off is usually undertaken in electrical mode. Combustion engine and electrical motor run because the scenario calls for – with electrical drive at low speeds, for instance in residential areas or within the metropolis centre, 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 per cent. Overall, the result’s a harmonious and consumption-optimised driving impression, thanks partly to the early upshifts of the AMG SPEEDSHIFT MCT-9G transmission. Suspension and steering are arrange for an emphasis on consolation. 
• Battery Hold” drive program: As within the “Comfort” driving mode, the combustion engine and electrical motor run primarily based on the scenario with a most enhance of round 25 per cent. The largest distinction is that the working technique retains the battery state of cost fixed. For instance, if the battery is at 75 per cent cost, it stays on this vary in “Battery Hold”. The use of the electrical motor is then restricted and optimised for low energy draw, which is compensated for by recuperation, for instance. Advantage for drivers: they’ll determine 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 interplay of the 2 drives primarily based on the scenario. More enhance from the electrical motor is enabled, as much as round 65 per cent. Sporty driving impression owing to extra agile accelerator response, shorter shift instances and earlier downshifts. A extra dynamic suspension and steering set-up. 
• “Sport+” drive program: beginning off with combustion engine and electrical motor and interplay of the 2 drives primarily based on the scenario. Even greater enhance efficiency of as much as 80 per cent. Extremely sporty character due to much more agile throttle response and focused torque intervention throughout upshifts with cylinder deactivation for optimum shift instances. Increased idle velocity 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. In this mode, all of the parameters are configured for optimum efficiency. Starting off with combustion engine and electrical motor and situational interplay of the 2 drives. Electric enhance energy of the electrical motor as much as 80 per cent. Strong battery recharging at low energy demand for optimum electrical availability. In addition, the “Boost Mode” could be known as up through the left steering wheel button. The enhance energy is then restricted to a most of 30 per cent with a view to preserve power reserves. These can then be used particularly on the race monitor for spontaneous energy demand through kick-down and 100 per cent enhance energy – for instance for an acceleration manoeuvre or highly effective acceleration out of corners. 
• “Slippery” drive program: optimised for slippery street circumstances, with decreased energy and a flat torque curve. Electric-only driving and recuperation adjustment are deactivated. 
• “Individual” drive program: particular person customisation of the drive, transmission, AMG DYNAMICS, chassis, steering and exhaust system. 

New sound expertise in all driving circumstances: electrical, hybrid and inside combustion engine 

When driving on all-electric energy, the legally required Acoustic Vehicle Alerting System warns the environment that the Performance hybrid is approaching. A specifically composed, low-frequency and speed-modulated AMG sound is emitted to the skin through a loudspeaker on the entrance and a soundbar with two loudspeakers on the rear. 

In addition, the AMG builders additionally use the exterior audio system for a extra superior sound expertise. For this objective, they decide up the true sound of the combustion engine through a stress sensor within the exhaust system and enrich it additional earlier than it’s emitted within the inside through the leisure sound system, thus making it potential to expertise the standard AMG sound at first hand. In addition, the sound is modulated through the present exterior loudspeakers as nicely. 

Recuperation selectable in 4 phases 

Because the high-performance battery is at all times within the optimum temperature window of round 45 levels on account of direct cooling, recuperation will also be optimised. Normally, a battery heats up strongly at a excessive recuperation fee so the power restoration stage 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. The driver can choose 4 completely different ranges of recuperation utilizing the right-hand AMG steering wheel button, with the power restoration being designed otherwise in accordance with the driving mode.

• Level 0: The automobile behaves equally to a typical 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 keep up the automobile’s energy provide. With the combustion engine switched off, friction losses within the drivetrain are decreased to a minimal. 
• Level 1: This is the usual setting, at which recuperation is already noticeable to the driving force, and corresponds roughly to the deceleration of a typical combustion engine when the clutch is engaged. 
• Level 2: Stronger recuperation, the brake pedal hardly must be used when shifting in site visitors.
• Level 3: Maximum power restoration, making so-called “one-pedal” driving potential as in an all-electric automotive. Depending on the driving standing, greater than 100 kW of energy could be fed again into the battery. 
• Special characteristic of the RACE drive program: On the racetrack, the driving force desires to squeeze the utmost time potential out of any braking motion. In the “RACE” drive program, recuperation is mechanically set at stage 1 to permit essentially the most reproducible automobile behaviour potential on the limits. 

AMG 2.0-litre engine with electrically assisted exhaust fuel turbocharger

The AMG 2.0-litre four-cylinder engine was developed solely on the firm’s headquarters in Affalterbach. Experienced technicians produce it in hand-built high quality in accordance with the “One Man, One Engine” precept. In doing so, Mercedes-AMG combines the craftsmanship of its extremely certified staff with the trendy manufacturing strategies of Industry 4.0 and a excessive diploma of digitisation.

The engine, with the inner designation M139l, is the world’s first manufacturing engine to be turbocharged with an electrical exhaust fuel turbocharger. This revolutionary system is derived straight from the expertise that the Mercedes-AMG Petronas F1 Team has been utilizing so efficiently within the premier class of motorsport for a few years. The new type of turbocharging ensures notably spontaneous response throughout the whole rev vary. This results in an much more dynamic driving expertise, whereas on the identical time growing effectivity. Compared to its C 43 4MATIC and SL 43 siblings, nonetheless, the turbocharger within the C 63 S is considerably bigger. This permits a greater airflow fee and thus extra energy. In addition, the built-in electrical motor is powered by the 400-volt high-voltage system (48 volts within the 43 fashions).

In the C 63 S, the four-cylinder unit produces 350 kW (476 hp) at 6725 rpm. This makes it essentially the most highly effective series-produced four-cylinder on this planet. The most torque of 545 Nm is out there at 5250 rpm. A belt-driven starter-alternator (RSG) combines the alternator and starter in a single element and is built-in into the 400-volt high-voltage system. The RSG begins the combustion engine and ensures the essential provide of the ancillary parts equivalent to air-con or driving lights.

Power 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 adjustments.

AMG RIDE CONTROL suspension with Adaptive Damping System 

The customary AMG RIDE CONTROL metal suspension with Adaptive Damping System combines sporty driving dynamics with a excessive stage of long-distance consolation. The foundation for that is offered by the entrance axle with specifically developed steering knuckles and supporting joints for the spring hyperlink, in addition to by the rear axle, which additionally options elastokinematics designed for dynamic dealing with. Based on this, the damping at every particular person wheel is repeatedly adjusted to the present demand – at all times bearing in mind the preselected suspension stage, the driving fashion and the situation of the street floor. In addition to an enchancment in experience high quality and luxury, this leads, above all, to a rise in driving security. There is a selection of three completely different damping maps (“Comfort”, “Sport” and “Sport+”). 

Rear axle steering combines agility with stability 

The customary rear axle steering operates with a most steering angle of 2.5 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 manoeuvrability. 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 automobile to steering instructions.

Good management and fade-resistant: the AMG high-performance composite brake system 

In holding with the acute output figures and the related efficiency, the AMG high-performance composite brake system with 6-piston mounted callipers on the entrance and 1-piston floating callipers on the rear is fitted as customary. The brake system impresses with very quick braking distances in addition to most stability and fade-resistance below heavy use.
