Mercedes-Benz S 400 BlueHYBRID

2009 Mercedes S400 Revealed

Mercedes-Benz has taken the off its highly anticipated S400 luxury sedan, the first hybrid vehicle in the world to use an lithium-ion battery pack.

The BlueHYBRID takes the 3.5-litre V6 the S350, gives it a mild in power to 205kW and mates it to a 15kW electric motor. down the driveline is a modified of M-B’s familiar 7G-Tronic automatic, whose ratios are to the hybrid powertrain’s power

Aside from its lithium-ion the S400 BlueHYBRID’s arsenal of gadgets aren’t anything however with stop-start regenerative braking and electric during hard acceleration, the still has a few tricks up its sleeve to improve fuel economy.

So, how does it drink? 7.9 litres per is the official figure, which in age of sub 5.0 l/100km diesels and hybrids particularly impressive. Still, not a bad figure for a large, heavy sedan — particularly one as as the S-class — and it’s a step up from the S350’s l/100km.

A 0-100kph sprint of 7.2 seconds is also quite considering the S400 BlueHYBRID’s posturing, while the electronically-limited top of 250kph should be more adequate for the occasional dash the Autobahn.

The S400 BlueHYBRID is to go on sale in Europe in June with the Chinese market in August and the US close behind in Prices have yet to be announced and has a due date for Australian deliveries, we’ll keep you posted on information as it comes to hand.

S 400 BlueHYBRID: The CO2 champion in the luxury with an efficient hybrid system and lithium-ion technology

is launching its first passenger car equipped with a hybrid system in summer 2009 the S 400 BlueHYBRID. The combination of a modified V6 engine and a compact hybrid makes the S 400 BlueHYBRID the world’s economical luxury saloon a spark-ignition engine. The NEDC fuel consumption is a mere 7.9 per 100 kilometres. This makes for the lowest CO2 emissions in this and performance class — 190 grams per kilometre. These figures go hand in hand assured performance. The 3.5-litre engine develops an output of 205 hp, the electric motor generates 15 hp and a starting torque of 160 Nm. The result is a output of 220 kW/299 hp and a combined torque of 385 newton metres. the new S 400 BlueHYBRID is the first series-production to be equipped with a particularly lithium-ion battery specially for automotive use. This is major contribution by Mercedes-Benz to the of the car.

The new Mercedes-Benz S 400 BlueHYBRID is on the S 350, and features an extensively drive train. This a further development of the 3.5-litre V6 engine, an additional magneto-electric the 7G-TRONIC seven-speed automatic specially configured for the hybrid the necessary operating and control the transformer and a high-voltage lithium-ion

The compact hybrid module is a electric motor that acts as a starter and generator. The offers a double benefit, as it helps to save fuel and driving enjoyment. This is due to the booster effect of the electric as it powerfully backs up the petrol with a maximum additional of 160 newton metres during the acceleration phase. The driver from the combined action of two units in the form of even impressive torque characteristics and effortlessly superior acceleration.

The hybrid module also has a start/stop function, which the engine off when the vehicle is at a — for example at traffic When it’s time to off again, the electric motor imperceptibly restarts the main unit. This likewise a contribution to fuel economy and protection: because the engine first time, and practically emissions are also minimised the starting phase.

When the is braked the electric motor as a generator, and is able to recover energy by a process known as Working in finely tuned the electric motor supplements the effect of the petrol engine and the brakes to deliver a smoothly braking action. The recuperated is stored in a compact yet highly lithium-ion battery in the engine and made available when This complex system is by a high-performance control unit, is likewise located in the engine

A milestone on the road to electrification

The of the modular, very compact and efficient hybrid drive is the new high-voltage lithium-ion battery, was specially developed for automotive use and is the such unit worldwide to be in a series-production vehicle. In this way is making a trailblazing contribution to the of the car, with the S-Class again playing the role of the trendsetter.

Major advantages conventional nickel/metal hydride include a higher energy and better electrical efficiency, with more compact and a lower weight. Thanks to installation in the engine compartment, it replaces the conventional starter the generous interior space and capacity of the S 400 remain unchanged. The battery not only stores for the electric motor, but is also to the 12-Volt onboard network via the to supply power to other consumers such as the headlamps and features. The completely newly battery system consists of the block with its lithium-ion and the cell monitoring system, the management function, the high-strength the cooling gel, the cooling the coolant feed and the high-voltage

Optimised thermal efficiency the engine’s fuel consumption

The V6 petrol engine with valve control has been re-engineered and improved. In the process the engineers made use of the advantages by the Atkinson principle,where the expansion is longer than the compression The intake valve is kept slightly longer between the and compression phases, which the engine’s thermal efficiency reducing the specific fuel and untreated emissions. A new cylinder different pistons and a modified with different camshaft increase the output by 5 kW/7 hp to 205 hp — while reducing consumption at the same time.

on rural journeys and on motorways, the S 400 achieves a further efficiency by moving the so-called operating of the petrol engine to produce a specific fuel consumption. The high start-off torque possible by the boost effect of the motor gives the driver a exhilarating feeling of powerful while fuel consumption and are reduced.

The electric motor improves

The compact, disc-shaped electric which is space-savingly installed in the converter housing between the and the 7G-TRONIC seven-speed automatic improves efficiency even This is a 3-phase AC external magneto motor, which a peak output of 15 kW/20 hp and a torque of 160 newton metres an operating voltage of 120 Volts.

compact motor also as a starter and generator, adopting the of both these conventional units.

Sophisticated interaction the internal combustion engine numerous additional functions that positively influence the and agility of the S 400 BlueHYBRID in equal Moreover, this disc-shaped effectively dampens torsional in the drive train, thereby reducing noise and vibrations in the The result is even more comfort for both driver and

Boost effect for even driving pleasure

The overall offers extensive benefits: by helping to save fuel, and by increasing driving pleasure the help of the boost effect, the electric motor gives assistance to the petrol engine its maximum torque of 160 newton right from the beginning of the acceleration phase. This that the hybrid drive of the S 400 BlueHYBRID moves off powerfully from very low engine as the torque curve impressively The additional torque of the hybrid also has a consistently positive during subsequent acceleration In all driving situations, the driver benefits from the interaction the two units in the form of powerful and muscular torque — but an increased fuel consumption.

The S 400 accelerates from zero to 100 in 7.2 seconds, and reaches an electronically top speed of 250 km/h. The S 400 BlueHYBRID the already very favourable fuel consumption of the conventionally S 350 by up to 2.2 litres per 100 kilometres. CO2 emissions are by 21 percent.

The start/stop function saves fuel when to a stop

In addition the hybrid features an extremely comfortable and start/stop function, which switches the engine off when the is rolling to a stop at less 15 km/h, for example before at traffic lights. When time to move off again, the motor immediately and imperceptibly the main engine as soon as the releases the brake pedal or the accelerator. This likewise to fuel economy and environmental as the engine restarts practically emissions are also minimised the starting phase. The vibrations and that are unavoidable when with a conventional starter are reduced to a minimum.

Steering and comfort remain unchanged, as the steering servo pump and the compressor are electrically powered. systems therefore continue to even when the vehicle is at a with the engine automatically off. The intelligent control is able to detect whether the is executing a turning or parking In this case the automatic function is temporarily deactivated, so these manoeuvres can be carried out in

Every braking action electric power for the battery

When the vehicle is braked, the motor acts as a generator and a process known as recuperation to the kinetic energy into energy. This energy is in the compact yet highly efficient battery, and made available required.

In the process the electric assists the engine braking of the internal combustion engine in two seamless stages: In stage on the overrun with no braking the electric motor acts as a and begins to recuperate energy. two commences as soon as the driver operates the brake pedal: the output is then increased and perceived as heavier deceleration by the Only when more pedal pressure is applied are the brakes activated in addition to In this way more electrical can be generated, while saving and tear on the hydraulic braking at the same time. To make the possible use of this double Mercedes engineers also a new braking system with a new pedal module for the S 400 BlueHYBRID.

located control electronics

control electronics are required to the 3-phase AC electric motor in the high-voltage DC network. The current is accommodated in the space formerly by the starter. As the control electronics up as a result of electric currents up to 150 amps, the system is equipped its own, additional low-temperature circuit.

Mercedes-Benz engineers accommodated the transformer in the right wheel arch, where it the exchange of energy between the high-voltage network and the 12-Volt network — and also the option of emergency starting jump leads if the standard should lose its charge.

To a consistently high level of efficiency, the transformer is likewise by a low-temperature circuit. The 12-Volt battery is installed in the boot, and not supplies the standard consumers but the monitoring system for the high-voltage with energy. Thanks to its with the lithium-ion battery, it is smaller in size and lighter usual.

Tried-and-tested automatic with a new configuration

Mercedes-Benz also adapted the well-proven automatic transmission to suit the drive, with newly software for the transmission management A newly developed auxiliary oil ensures reliable lubrication of the even during phases the internal combustion engine is off.

This complex is managed by the modified high-performance control unit. This extensive functions, and distinguishes operating conditions such as traffic, rural journeys, driving or slow manoeuvring.

status is shown in the instrument

The driver is also able to the status of the hybrid drive visually. The instrument cluster has a centrally positioned, display the energy flow during and recuperation phases, as well as the charge status.

Seven-stage concept in addition to the Mercedes-Benz

As is usual at Mercedes-Benz, the development gave safety aspects very special attention. incorporated into the series-production car long years of Daimler experience with fuel-cell The challenge lay in not only complying all the worldwide and in-house legal test requirements, but also in the greatest possible safety for the components. This safety already applies in production, workshop personnel during and maintenance, and also takes the services into account passengers need to be recovered an accident.

Accordingly the hybrid technology of the S 400 is equipped with an extensive safety concept.

1. In the first all the wiring is colour-coded to eliminate and marked with safety This prevents assembly in production, and makes the regular checks easier to carry

2. The second stage comprises contact protection for the entire by means of generous insulation and developed, dedicated connectors.

3. As of the third stage, the world’s lithium-ion battery to be used in a model has been given a package of carefully coordinated measures. This innovative is accommodated in a high-strength steel and also secured in place. the battery cells in a special gel dampens any jolts and knocks. is also a blow-off vent a rupture disc and a separate circuit. An internal electronic continuously monitors the safety and immediately signals any malfunctions.

4. The stage of the safety concept separation of the battery terminals, safety-wiring for all high-voltage components and monitoring by multiple interlock This means that all components are connected by an electric In the event of a malfunction the high-voltage is automatically switched off.

5. discharging of the high-voltage system as as the ignition is switched to Off, or in the of a malfunction, is part of the fifth

6. During an accident, the high-voltage is completely switched off within of a second (stage six).

7. As the and last stage, the system is monitored for short circuits.

to its compact dimensions and modular the additional weight of the overall is only 75 kilograms — the comprehensive safety systems. The driving experience for which a is known is therefore ensured by trailblazing and very versatile which can be used for practically all model series. Moreover, the remains unchanged at 595 kilograms.

The high-performance engine management responds very sensitively to driving conditions, and optimally the drive system for the relevant ensuring that both consumption and emissions are kept to the possible level.

At standstill the engine is usually switched and therefore consumes no fuel. The drive of the refrigerant compressor and servo pump allows operation of the air conditioning and power Comfort is in no way compromised, and is at the same level as in all S-Class models.

When rolling to a stopthe function is activated as soon as the is interrupted in any way (foot off the accelerator, braking). Once the vehicle falls below 15 km/h, the engine is automatically switched

If the driver brakes using the pedal, the electric motor begins to convert the vehicle’s energy into electrical In this case the electric acts as a generator, storing the energy as electrical energy in the battery. This process like a stronger engine effect to the driver. The conventional brakes at the wheels are not yet employed, wear and tear. The disc are only activated if the driver heavy pressure to the brake braking the car together with the brake and recuperation.

Once the selects R (reverse) in the 7G-TRONIC transmission when manoeuvring, automatically activates the Manoeuvring and prevents the start/stop function switching off the engine at short, intervals.

The advantages of the hybrid system really come their own in city traffic, frequent stops at red traffic Already switching off the petrol as the car frequently coasts to a stop lowers the fuel consumption and while the long recuperation increase the battery charge. The motor ensures particularly and rapid restarting when the function is active.

On rural are frequent changes between constant speed and recuperation Depending on the nature of the route, quantities of recuperation energy are to reduce fuel consumption and The more braking and acceleration there are, the better: and downhill gradients, as well as dynamic stretches, make for the savings.

The hybrid effect is less important on motorways, thanks to specific modifications to the V6 engine and the 7G-TRONIC automatic the driver is also able to significant fuel savings and lower emissions on fast stretches like these.

The S 400 is produced at the Sindelfingenplant, together the other S-Class models. The engine, 7G-TRONIC automatic and electric motor are first put to form a hybrid module, delivered to the production line as a The market launch in western is planned for June 2009; is expected to follow in August and the USAin September 2009.

The new S 400 BlueHYBRID exemplifies the of Mercedes-Benz, whose declared aim is to the brand’s customers economical and compatible premium cars without compromising in terms of brand attributes such as comfort and a superior driving

Major areas of development include modular drive which are used on a stand-alone or in combination depending on the vehicle operating profile and customer — Mercedes-Benz has already how this applies to the product in its Road to the Future. In this Mercedes-Benz also provides an on the future of the internal combustion with the innovative DIESOTTO in the F 700 research car.

Dedicated for different requirements

The requirements for the of the future are complex and multi-facetted. is because the world population, and the demand for mobility, are set to increase over the next few decades. At the time the world’s natural are becoming increasingly scarce, and more and more expensive for consumers and car manufacturers. Depending on the region, there are also very different legal with respect to the environmental of vehicles. Examples include the zones already established in European cities, or the legally quotas for emission-free vehicles in

These developments are already a noticeable effect on customer In addition to economic factors above all increasing fuel — the environmental compatibility of a car is increasingly important as a buying What is more, the day-to-day requirements of customers are becoming and more individual and distinctive: covering long rural have different requirements those who mainly or even drive in densely populated areas.

In the view of Mercedes-Benz, is therefore no single technology will provide the ideal for sustainable mobility in the future. the company offers versatile, solutions to meet these varied requirements. The individual deliver their benefits in of optimal fuel consumption and in the specific areas of application The approach taken by Mercedes-Benz vehicle concepts with drive technologies, which that customer benefits and compatibility are always jointly
