SPY: First scoops of the future 2017 Mercedes-Benz E-Class Limousine (W 213)

A while ago, spy photographers have spotted shots of a modified C-Class vehicle which appeared to be an early test mule for the forthcoming W 213 series E-Class. Recently, the very first finished body test prototypes of the business class limousine have rolled out on the streets of Germany.

The first impression while examining the photos is that the next generation E-Class will further evolve the design philosophy launched on the new C-Class. The anti-wedge profile is demonstrated by the long bonnet and shorter rear volume. The prototype is heavily cladded with camouflage, so it is hard to draw any further conclusions. What is for sure is that, like the C-Class, the E-Class is also set to become even more elegant with the advent of the new generation, towards the end of 2016.

Details are scarce at the moment, but what we know certainly is the W 213 will be introduced as technological masterpiece. The future E-Class will introduce an all new, gesture-based interior architecture, along with a highly enhanced COMAND Online infotainment system, similar to the Human Machine Interface that was previewed back in 2007 on the F 700 Research Vehicle.

Several new assistance and safety technologies will also make their way onto the new E-Class. For the first time since the 90s, Mercedes-Benz will return to straight-six petrol and diesel engine. The new modular units will be offered in several output stages, covering the 200-400 hp range. They will use spray-guided direct injection, two-stage turbocharging, ECO start/stop technology and several systems to further reduce fuel consumption and improve efficiency.

C 63 AMG: some 40,000 vehicles sold worldwide - The C-Class from AMG: a success story with eight cylinders

The story of the high-performance C-Class powered by eight-cylinder engines began in 1997 with the C 43 AMG. The successors in the guise of the C 55 AMG and C 63 AMG underscored the significance of the powerful V8 engines for AMG's brand promise of "Driving Performance". With sales of some 40,000 vehicles, the C 63 AMG is also the best-selling AMG model to date. One thing is clear already: its successor will further raise the bar in terms of performance and fuel consumption. The power source of the new C 63 is of course once again a V8 engine and closely related to that of the Mercedes-AMG GT.

The first C 63 AMG celebrated its market launch in 2008. Around 8000 of these high-performance C-Class vehicles were sold in 2012, the year with the strongest sales. The successor model will shortly celebrate its world premiere as a saloon and as an estate model. Under its bonnet is a highly efficient AMG 4.0-litre V8 Biturbo engine based on the sports car engine of the Mercedes-AMG GT.

"It goes without saying that the successor to the current C 63 AMG will again be powered by an eight-cylinder engine. We owe that to our loyal fans, plain and simple", says Tobias Moers, CEO of Mercedes-AMG GmbH. "The AMG V8 Biturbo engine mesmerises not only with maximum power and torque, but also with the absolute best fuel economy in the comparative segment".

The world's most economical high-performance eight-cylinder engine

Under the bonnet of the C 63 AMG's successor is an all-new 4.0-litre V8 Biturbo engine. The eight-cylinder Biturbo engine will deliver exceptional performance with an unrivalled power output range of up to 375 kW (510 hp) and 700 Nm of torque. At the same time the eight-cylinder high-performance vehicle impresses with low emissions and the world's best fuel economy in the segment. The latest member of the AMG BlueDIRECT engine family sets absolute standards with a fuel consumption of 8.2 litres/100 km (NEDC combined).

Début for the C 63 AMG in 2007: more AMG than ever before

The 40th anniversary of Mercedes-AMG GmbH was a special reason for AMG fans to celebrate. The C 63 AMG (model series 204) marked a new standard for high-performance sports saloons. The top-of-the-line C-Class model was powered by an AMG 6.3-litre V8 engine. With a rated power output of 336 kW (457 hp) and a peak torque of 600 Nm the high-rev naturally aspirated engine was unrivalled in this segment. Powered by this engine the C 63 AMG accelerated from 0 to 100 km/h in 4.5 seconds (Estate: 4.6 sec.); the top speed was limited electronically to 250 km/h. In conjunction with the AMG Performance package Plus that became available as an option in 2009, power output jumped to 358 kW (487 hp). Engine components from the SLS AMG super sports car increased the V8 engine's willingness to rev and its agility.

The power was transmitted by the AMG SPEEDSHIFT PLUS 7G-TRONIC transmission with three transmission modes and double-declutching function. The sports suspension with 18-inch light-alloy wheels in conjunction with a completely redesigned front axle, speed-sensitive sports steering and 3-stage ESP® offered maximum driving pleasure and markedly dynamic handling.

Design and equipment: more stand-alone character than ever before

The C 63 AMG differed from the production C-Class more clearly than ever before: in addition to AMG bodystyling with power domes, flared front wings, a rear bumper with diffuser insert, a sports exhaust system with two chrome-plated dual tailpipes and a spoiler lip added hallmark brand highlights. The interior was dominated by sports seats with integral head restraints, the three-spoke AMG Performance steering wheel with flat bottom, and the tube-design AMG instrument cluster with special main menu.

Model update in 2011: technical upgrades, Coupé and Black Series

With the model update in January 2011, the AMG SPEEDSHIFT MCT 7-speed sport transmission boosted driving dynamics while playing a part in reducing fuel consumption at the same time. Numerous design modifications and technical updates increased the car's appeal. In addition, the C 63 AMG Coupé came onto the market: The attractive two-door car celebrated its market launch in July 2011.

That same year Mercedes-AMG presented the temporary highlight in the form of C 63 AMG Coupé Black Series – a fascinating sports car for passionate lovers of powerful vehicles. With a maximum power output of 380 kW (517 hp) and 620 Nm of torque, the high-performance Coupé remains the most powerful C-Class model to date. Thanks to technology transfer from the SLS AMG – the super sports car supplies the forged pistons, piston rods and lightweight crankshaft – the Coupé delivered high-calibre performance. The C 63 AMG Coupé Black Series sprinted from 0 to 100 km/h in 4.2 seconds, the top speed was an electronically limited 300 km/h.

The adjustable coil-over suspension was also a contributing factor in the hallmark AMG Driving Performance, as was the high-performance compound braking system and the functional standard equipment level. The AMG Track package and the Aerodynamics package were available to further enhance driving dynamics.

Since April 2013: the C 63 AMG "Edition 507"

In April 2013, the C 63 AMG "Edition 507" celebrated its market launch.A power output of 373 kW (507 hp) and now 610 Nm of torque lend all three body styles of the C 63 AMG an even more dynamic character. The high-performance composite braking system, part of the standard equipment of the "Edition 507", likewise delivers enhanced performance. The special dynamic nature is also reflected in distinctive, sporty exterior and interior highlights – from the bonnet with high-gloss black air vents and the 19-inch forged cross-spoke wheels to special flourishes in the interior. The "Edition 507" continues to be available as a Coupé.

Official F1® Medical Car in Formula 1® and Safety Car in the DTM racing series

With the C 63 AMG Estate as the Official F1® Medical Car Mercedes-AMG has been helping to ensure maximum safety in Formula 1® since 2008. In the popular DTM German Touring Car Masters racing series the C 63 AMG Coupé Black Series sees duty as the Safety Car. In the 2014 DTM season Mercedes‑Benz starts seven DTM Mercedes AMG C-Coupé racing cars.

The new high-performance model of the latest C-Class can look back on an impressive family history. There are five direct ancestors, the C 63 AMG, C 55 AMG, C 32 AMG, C 43 AMG and the C 36 AMG. The 190 E 2.3-16 and 190 E 2.5-16 with the legendary "sixteen-valve" engine and the 190 E 3.2 AMG with powerful AMG six-cylinder engine may rightfully also be considered its spiritual forefathers.

The new Mercedes-Benz S 500 PLUG-IN HYBRID: Efficiency = Performance

The new Mercedes-Benz S 500 PLUG-IN HYBRID blends an ultramodern hybrid drive configuration with the unique innovations and the luxurious equipment and appointments of the S-Class. The luxury saloon with a long wheelbase impresses with exceptional dynamism and efficiency. Thanks to standard pre-entry climate control it also offers unique climate comfort. The first certified three-litre luxury saloon in the world is a further milestone on the road to emission-free mobility. The first S 500 PLUG-IN HYBRID cars go to the customers this month.

"The S 500 PLUG-IN HYBRID is the first luxury saloon with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and a high-tech hybrid drive," says Prof. Dr. Thomas Weber, member of the Daimler Board of Management responsible for Group Research and Mercedes-Benz Cars Development.

"The new S 500 PLUG-IN HYBRID offers our customers the entire range of innovations that make our new S-Class so successful, and thanks to its intelligent operating strategy ensures outstanding driving pleasure and dynamism combined with the highest efficiency. Moreover, it allows completely emission-free driving for up to 33 km," adds Ola Källenius, Executive Vice President Sales and Marketing Mercedes-Benz Cars.

The Mercedes-Benz S 500 PLUG-IN HYBRID offers a system output of 325 kW and 650 Nm torque, sprints from 0 to 100 km/h in just 5.2 seconds and can drive up to 33 km purely electrically. The certified consumption is 2.8 litres/100 km, which corresponds to 65 g CO2/km emissions. Key elements of this impressive output are the V6 biturbo and the intelligent hybrid drive.

Following the S 400 HYBRID and S 300 BlueTEC HYBRID, the S 500 PLUG-IN HYBRID is the third hybrid model in the new S-Class. Its new high-voltage lithium-ion battery with an energy content of 8.7 kWh can be externally recharged via the charging socket in the right side of the rear bumper.

All three hybrid S-Class models have environmental certificates. These document the models’ environmental performance from development through to recycling, across the entire lifecycle, and the performance is certified to internationally recognised standards by independent experts. Regarding CO2 emissions the certificate of the S 500 PLUG-IN HYBRID states: "Over the entire lifecycle, comprising manufacture, use over 300,000 kilometres and recycling, clear advantages result compared with the S 500. External charging with the European electricity mix can cut CO2 emissions by some 43 percent (35 tonnes). Through the use of renewably generated hydroelectricity a 56 percent reduction (46 tonnes) is possible."

The hybrid transmission is based on the 7G-TRONIC PLUS 7-speed automatic transmission. The plug-in-hybrid system in the S-Class is based on the Mercedes-Benz parallel hybrid modular system. The common system-specific feature is the additional clutch integrated between combustion engine and electric motor. On the one hand, it decouples the combustion engine during purely electric operation; on the other hand, if the combustion engine is employed it affords the possibility to move off drawing on the performance of a wet start-up clutch. The clutch then substitutes for the torque converter and requires no additional space owing to its complete integration in the torque converter housing.

In order to strengthen the customers' trust in the new, innovative plug-in drive technology, for the S 500 PLUG-IN HYBRID Mercedes-Benz is for the first time issuing a certificate and thus a promise to perform for the high-voltage battery and plug-in components (e.g. electric motor and power electronics). This ensures that every technical malfunction within a period of six years after initial delivery or registration, or up to a mileage of 100,000 kilometres, is corrected by Mercedes-Benz.

Haptic accelerator pedal: support for the driver

Climb in, start, drive off and, as well as exemplary efficiency, on request experience via kickdown the special acceleration of the electric motor – this is how easy hybrid driving with the new S 500 PLUG-IN HYBRID is. For in everyday use it moves just as easily as any other automatic transmission car.

In the background, depending on the chosen operating mode the intelligent operating strategy automatically selects the ideal combination of internal combustion engine and electric motor and in so doing not only adapts its strategy according to the charge status of the battery; it also foresightedly adjusts it according to the traffic or route. But anyone wanting to can also intervene manually and with the aid of four operating modes and three transmission modes regulate the hybrid interplay themselves.

What is known as the haptic accelerator pedal can signal via a double impulse when drivers should take their foot off the accelerator for sailing and recuperating. During electric operation it can supply the driver with feedback on the switch-on point of the combustion engine. The energy flow is shown in all operating states in the instrument cluster and in the central display, if this is selected by the customer.

The technical data at a glance:

Extensive standard equipment, extended pre-entry climate control

The standard equipment in the S 500 PLUG-IN HYBRID is extensive and offers a world premiere: the extended pre-entry climate control. This is target value controlled. meaning that at the start of the journey the S-Class is air conditioned to the preset temperature if the driver has entered the departure time, via Mercedes connect me, for example. This is possible due to the electrically driven refrigerant compressor and electric heating elements for the heated air. In addition to this, when preheating it is not just the interior air but also the seats, steering wheel and armrests in the doors and centre console which are heated, and when cooling the seat ventilation is also activated if the respective optional extra is on board.

Also standard in the S 500 PLUG-IN HYBRID, which is only available with a long wheelbase, are for example LED High Performance headlamps and LED tail lights, leather upholstery, COMAND Online, touchpad, THERMOTRONIC automatic climate control plus seat heating also in the rear, Memory package for driver and front passenger, ambient lighting in seven colours and the air suspension AIRMATIC with continuously variable damping system. The basic safety equipment includes PRE-SAFE®, COLLISION PREVENTION ASSIST PLUS (collision warning including Adaptive Brake Assist), ATTENTION ASSIST, PRE-SAFE® impulse, Crosswind Assist and Traffic Sign Assist (traffic sign recognition incl. wrong-way warning function and display of speed limits in the instrument cluster). Over and above this a multitude of unique optional extras is available.

The Mercedes-Benz hybrid strategy: emphasis on plug-in drives

Following the S 400 HYBRID and S 300 BlueTEC HYBRID, the S 500 PLUG-IN HYBRID is the third hybrid model in the new S-Class. The series production launch of this technology began at Mercedes-Benz in 2009. The company is up there among the leaders in the field of purely electric mobility, too. In the years to come the main emphasis will be on plug-in hybrids.

Hybrid drives, the combination of internal combustion engine and electric drive, help cut overall fuel consumption and boost performance, since the electric drive replaces or supports the combustion engine whenever the engine characteristics are unfavourable — normally in part-load operation when little power is required.

The largest potential for lowering the energy consumption of hybrid drive systems lies in maximising energy recovery during coasting and braking. Upon depressing the brake pedal the deceleration is initially effected by the electric motor and not by the disc brakes. The hybrid models of the new S-Class are the first to use a recuperative braking system of the second generation. It ensures an unnoticeable overlapping of the conventional mechanical brakes and the electric braking performance of the electric motor in generator mode.

Intelligent operating strategy

For efficient operation, foresighted driving, avoiding unnecessary braking and accelerating manoeuvres, has always been the best strategy. This gains an all new importance in a hybrid model: braking manoeuvres serve not only deceleration, but can also be used to recuperate energy. And the route has considerable influence on the most efficient charging and discharge of the high-voltage battery.

The intelligent operating strategy supports the driver comprehensively yet unobtrusively to achieve the most efficient driving style. The control strategy, for example, seeks to ensure that the battery, if at all possible, is flat at the end of an uphill stretch so that it can be recharged going downhill. Another key point is the requirement that urban areas be reached with a fully charged battery, if possible, so that the vehicle can be operated in stop-and-go traffic electrically – frequently and efficiently.

In the S 500 PLUG-IN HYBRID the energy management system basically covers these three areas:

- route-based: automatically or by way of four operating modes
- driver-based: by way of three transmission modes
- traffic-based: with the aid of radar.

Charging: power from a socket

The battery of the S 500 PLUG-IN HYBRID is safely fitted into the rear end of the S-Class to save space. An intelligent on-board charging system enables the battery to be charged at any conventional household power socket. The supply of electricity to the car will be made even easier in future through inductive, cableless charging.

The S 500 PLUG-IN HYBRID stores electric energy in a lithium-ion battery on lithium-iron phosphate basis. The water-cooled energy storage unit has an overall capacity of 8.7 kWh, a total weight of 114 kg and a spatial volume of 96 litres.

To ensure highest levels of crash safety and dynamic handling and also maximum boot space, the housing is made of die-cast aluminium and the high-voltage battery is located in the rear of the vehicle above the rear axle. The space available there is put to optimal use, and the S 500 PLUG-IN HYBRID thus takes first place among the plug-in hybrids in terms of boot capacity (395 litres) and luggage compartment accessibility.

The high-voltage battery of the S 500 PLUG-IN HYBRID can be charged via external electricity mains using a 3.6 kW on-board charger. The unit is permanently installed in the vehicle and charges single-phase up to 16 A. The connection for the charging cable is located under a flap in the rear bumper underneath the tail light on the right-hand side. An automatic lock ensures that the cable cannot be separated from the vehicle by unauthorised persons. The new S-Class can be charged in two hours anywhere in the world, e.g. at a wallbox or a charging pole (400 V, 16 A). Alternatively, charging via house connection is also possible, of course. Depending on the connection a charge time e.g. of two hours and 45 minutes can be attained (with 230 V and 13 A)[1].

Next step: S 500 PLUG-IN HYBRID – unplugged

One of the next steps on the way to the perfect electric vehicle and plug-in hybrid is cableless charging. Inductive battery charging will make the handling of electric vehicles and plug-in hybrids even more convenient. Mercedes-Benz will test this "unplugged" technology with the S 500 PLUG-IN HYBRID in order to develop a genuine S-Class solution, in terms of comfort and ease of operation, for the charging of the high-voltage battery.

The history: leadership role in the premium segment

In 1982 Mercedes-Benz presented the first concept vehicle with hybrid drive – a two-cylinder horizontally opposed engine served to charge the battery. A number of other experimental vehicles followed until in 2009 the world's first standard-specification hybrid drive with lithium-ion battery debuted at Mercedes-Benz: this S 400 HYBRID was the most fuel-efficient petrol-powered luxury saloon for a long time. And the most successful hybrid in its segment: with around 20,000 buyers.

Based on the 7G-TRONIC PLUS automatic transmission the second-generation hybrid transmission evolved. It premiered in 2012 in the E 300 BlueTEC HYBRID, the first diesel hybrid in the premium segment worldwide. By combining the efficiency of a diesel engine with the advantages of the hybrid drive, Mercedes-Benz set another milestone in the development of the automobile and advanced into consumption regions of 4 litres of diesel per 100 km in the luxury saloon segment.

With the C 300 BlueTEC HYBRID Mercedes-Benz has completed its hybrid portfolio below the luxury class. Moreover, in 2014 the B-Class Electric Drive, already on the market in the USA, will also become available in Europe to supplement the hybrid range.
