Optimization of internal combustion engine
Greater efficiency, less emissions: Optimizing internal combustion engine and BlueEFFICIENCY (blue performance) Integrated environmental technology has become today’s ideal of the sustainable development of transportation solutions

• optimization of internal combustion engine
• BlueEFFICIENCY (blue performance) Integrated Environmental Science and Technology

From passenger cars to commercial heavy-duty trucks, gasoline engines and diesel engines will be a very long period of time continue to serve as the backbone of transportation. Therefore, the Mercedes – Benz “Road leading to zero emissions,” the first phase is to optimize the internal combustion engine. On the one hand, Mercedes – Benz is committed to research and development including the new four-cylinder diesel engine and a new generation of gasoline direct injection engines, including the world’s most advanced engine. On the other hand, Mercedes – Benz also introduced the BlueEFFICIENCY (blue performance) integrated environmental technology, by optimizing the engine, reducing weight, reducing air resistance, friction reduction, energy management, energy recovery and other energy-saving emission reduction technology, a set of effectively reduce energy consumption, improve fuel efficiency, and maximize the environmental effects. With this set of energy-saving emission reduction technology, automotive fuel consumption can be reduced up to 12%. From the A-Class to the S-Class, Mercedes – Benz on all models are applied BlueEFFICIENCY (blue performance) integrated environmental technology, to the end of 2009, a total of more than 60 Mercedes – Benz model application of the technology. 2010 Mercedes – Benz will this highly efficient and clean vehicles be extended to 85 models.

Optimization of internal combustion engine

In the process of developing a new generation of engines, Mercedes has set a clear goal, that is: Let the gasoline engines and diesel engines as efficient, and for diesel engines and gasoline engines cited as clean. In the meantime, energy-efficient power systems will also continue to maintain a Mercedes – Benz unique high performance. There is no doubt that Mercedes has already achieved this goal all-round way.

Second-generation gasoline direct injection engine can significantly reduce fuel consumption by up to 10%, while output increased significantly. Compared with conventional supercharged engine models, equipped with turbo direct injection engine, the car has a more efficient energy management standards, its greatest advantage is that even running direct-injection system; with previous inlet injection system compared to the injection system significantly improves energy efficiency. The fuel vaporization in the cylinder reduces the combustion temperature, thereby reducing the tendency of the engine knocking at the same time, increased compression. In addition, the engine R & D staff also uses intelligent energy management system, thermal management system can prevent the coolant in the engine in a cold state, through the cylinder, so that the engine’s combustion chamber can be quickly heat up when needed, thereby further reducing fuel consumption.
Last year in November, is equipped with on behalf of Mercedes – Benz latest environmental protection technology standard BlueEFFICIENCY (blue performance), a new environmental technology E 200 CGI, E 260 CGI and the E 260 CGI coupe officially landed the Chinese market, not only the Mercedes-Benz’s achievements in optimizing internal combustion engine, even the new E-Class philosophy of environmental protection into a whole new level. They are equipped with a new design of the CGI-cylinder direct-injection turbocharged engine is that at present the most efficient automotive manufacturing, and guided the field of engine design trends and direction. The all-aluminum 1.8-liter inline four-cylinder engine, rely on CGI variable valve timing technology, high-pressure turbo technology as well as fixed-cylinder fuel injection technology, the new E 200 CGI cars have up to 135 kW power output, while in 1800 to broad engine speed range of 4600 to provide a strong torque of 270 Nm, 100 kilometers just 8.2 seconds to accelerate. The combined consumption is only 100 kilometers of its 7.6 liters per kilometer of carbon dioxide emissions of only 180 grams, in full compliance with EU V emission standards.

CGI also equipped with aluminum cylinder direct-injection turbocharged 1.8-liter inline four-cylinder engine, the new E 260 CGI cars tend to rely more sports performance and tuning the engine for the popular dynamic car offers consumers more choices. The new E 260 CGI cars power output of 150 kW and 310 Nm, 100 kilometers to accelerate just 7.8 seconds, and the corresponding fuel consumption of 7.8 liters per hundred kilometers, carbon dioxide emissions of 185 grams per kilometer, in line with EU V emission standards.

The new E 260 CGI two-door coupe powered by a 1.8-liter aluminum inline four-cylinder CGI-cylinder direct-injection turbocharged engine with 150 kW and 310 Nm of strong power output, driving Cikuan car can accelerate from standstill to the speed of 100 kilometers just 7.4 seconds. Together with Mercedes – Benz BlueEFFICIENCY a leading environmental technology, gives a completely new E 260 CGI coupe the world’s top environmental standards. Integrated fuel consumption of only 100 kilometers of its 7.5 liters per kilometer of carbon dioxide emissions as low as 175 grams, in line with EU V emission standards.

BlueEFFICIENCY (blue performance) Integrated environmental technology: a set of efficient and environmentally friendly solutions

In order to further achieve fuel efficiency, Mercedes – Benz has developed a BlueEFFICIENCY (blue performance), an integrated environmental protection technology.

BlueEFFICIENCY (blue performance) Integrated environmental technology is a visionary leader in environmental technology, but also a set of general energy-saving emission reduction solutions. The main purpose is through optimization engine, reduce weight, reduce air resistance, friction reduction, energy management, energy recovery and a series of measures to effectively reduce energy consumption, improve fuel efficiency, and maximize the environmental effects. With these technologies, the vehicle can reduce fuel consumption up to 12%.

For example, relying on BlueEFFICIENCY technology, outstanding performance, the new E-Class 23% lower than before, fuel consumption, environmental protection for today’s luxury car model. From the power steering to a low-resistance tires, fuel pump to the alternator from a large number of components, engineers through a variety of ways to achieve fuel-saving effect. These fuel-efficient manner, including parts lightweight design, change shape, to improve parts of the functionality and effectiveness of controls and so on. While many individual measures can only improve the fuel economy of 12 percentage points, but the combination of these measures can significantly reduce fuel consumption.

Energy Management: Smart environmental protection measures

To the extent possible, to save fuel and reduce carbon dioxide emissions,

BlueEFFICIENCY (blue performance) Integrated environmental technology through optimization of automatic transmission, energy-efficient power steering pump, oil supply-demand adjustment of the controlled fuel pumps and other energy management, to avoid unnecessary energy loss. Mercedes – Benz for the new E 200, E 260 and E 260 two-door coupe equipped with technical innovations converter five-speed automatic transmission, can reduce the hydraulic pressure loss, thereby reducing fuel consumption.

Power steering system is designed to prevent energy loss based on lower fuel consumption and therefore an intelligent solution. Conventional steering system of the power steering pump is always running at full power, while the new E 200 and E 260 of the power steering pump uses an on-demand control valve. When the driver do not need to turn to support, such as in a straight line driving, the electronic control module will power steering pump to run power to a minimum. This system has the advantage of engine-driven oil pump does not require the provision of energy (or in the drive when the oil pump only provide very little energy). However, when the driver turned the steering wheel, power steering pump flow spontaneously increases again. In this case, the system is also on-demand operation, according to the current steering angle, engine speed and vehicle speed to adjust pump operation power.

In order to ensure energy-demand management, the new E 200 and E 260 gasoline engine to use a controlled fuel pump. In this process, the engine control module only in the full-load operation to provide maximum pump flow rate. In other driving mode, fuel pump to adjust according to demand oil supply and pressure. In this way, the engine can save 0.15 liters per 100 kilometers of fuel (NEDC test results).

Energy recovery systems: the energy generated when braking for recycling

Every time the vehicle during braking, kinetic energy will be converted into heat, and are lost. Now, Mercedes – Benz BlueEFFICIENCY technology includes an efficient AC management system, through this system, regardless of when the vehicle brakes, the system can be converted into kinetic energy, and battery charging and, therefore, will lose the energy of the original re-use them. In the opposite situation, such as vehicle acceleration, or full battery case, AC power management system automatically switches to the “no-load” state, has reduced the load on vehicle drive system. This system can, in theory, 0.1 liters per 100 kilometers to save fuel, but in actual driving process, especially in urban traffic situations where it can achieve savings of 0.2 liters per 100 kilometers of fuel effects.

Aerodynamic design and low-resistance tires: reducing air resistance and friction, further reducing fuel consumption

Air resistance and the speed is proportional to; when the speed limit is only 80 km / h, air resistance would account for all the resistance of the sum of 50%. These figures show that the aerodynamic drag on fuel consumption and how a big impact. In particular, the speed is high, the air resistance the greater the impact on fuel consumption. European NEDC test shows that in the average speed of less than 33 km / h case, drag coefficient reduced by 0.01 per one hundred kilometers to save only 0.04 liters of fuel oil; and if the vehicle to 130 km / h high-speed driving, the lower 0.01 Drag coefficient was 0.15 liters of fuel can be saved / 100 kilometers.

Accurately simulated by computer calculations and wind tunnel experiments, Mercedes – Benz engineers to optimize the maximum extent possible the new E-class aerodynamic body structure, will be the new E-class drag coefficient down to 0.25, also a new E-class Cars became the aerodynamic efficiency of the market segment the best production model. The new E-class coupe is by virtue of the drag coefficient of 0.24 to become the world’s most outstanding aerodynamic production car.

Tires will also help to fuel consumption to a minimum. The new E-class equipped with newly developed tires, 17% in reducing rolling resistance while still maintaining excellent handling and grip.

HYBRID: with practical-oriented hybrid technology

As “the road leading to zero emissions,” the second stage, Mercedes – Benz has developed with practical-oriented modular hybrid system to further enhance the vehicle power system in daily use efficiency. The standard components can be based on performance and applications, providing a large number of extension method: different levels of hybrid module, and the ability to adapt to the largest displacement gasoline engine and diesel engine battery. With the engine, all modules are compatible with hybrid-speed automatic transmission 7G-TRONIC7. In this basis, whether it is a weak hybrid, you can still run strong through the all-electric hybrid, Mercedes – Benz, both seeking to perfect. Plug-in hybrid electric hybrid technology represents the next stage of development. In the plug-in hybrid, the battery can be recharged through a normal household outlet, thereby increasing the power-driven vehicles traveling mileage. Adoption of hybrid modular systems, Mercedes – Benz in environmental protection technology, economy vehicles, safety and comfort set a new standard for the industry.

From the summer of 2009, Mercedes – Benz became the first to offer hybrid car (S 400 HYBRID) of the European car manufacturers. As a first application of the most advanced lithium-ion battery technology, high-volume hybrid sedan, S 400 HYBRID is known as the world’s most fuel-efficient gasoline engine limousine.

S 500 plug-in hybrid cars displayed Mercedes – Benz a leader in the modular hybrid system success. The electric-powered vehicles in the full circumstances can travel 30 kilometers to achieve complete zero-emission driving, its standard fuel consumption of only 3.2 liters / 100 km, carbon dioxide emissions by only 74 g / km. In creating excellent fuel economy at the same time, S 500 plug-in hybrid cars have continued the traditional S-Class top-level comfort, safety and superior dynamic performance. In the V6 gasoline direct injection engines, hybrid module, as well as the high-voltage lithium-ion battery pack, under the joint action, S 500 plug-in hybrid car from 0-100 km / h acceleration time of just 5.5 seconds. S 500 plug-in hybrid car’s innovative drive systems will be among the next generation S-class market.

Moreover, in the just-concluded Geneva Motor Show, the Mercedes – Benz’s first diesel hybrid E 300 BlueTEC HYBRID peeled off the first mystery. Vehicle equipped with a 2.2-liter four-cylinder diesel engine equipped with a hybrid module, while maintaining a strong power output, while significantly reducing energy consumption and carbon dioxide emissions – 4.1 liters fuel consumption is only 100 kilometers, while the emissions of carbon dioxide per kilometer is only 109 grams. E 300 BlueTEC HYBRID installation of electric motors can also be ordered to rely on pure power to achieve zero-emission driving.

A milestone in the process of electrification

As the world’s first powered by lithium-ion battery production models, a new generation of S 400 HYBRID the perfect interpretation of the Mercedes – Benz in the automotive technology, the world leader in the automotive electrification process, a landmark of special significance. Improved version of its V6 gasoline engine with a compact hybrid module makes the S 400 HYBRID the combination has become the world’s most efficient gasoline engine limousine. NEDC tests in Europe, it is only 8.0 liters fuel per hundred kilometers, while emissions of carbon dioxide per kilometer of only 188 grams, the same level in the world, the car set a new benchmark to determine a new generation of S 400 HYBRID “Luxury Car the field of low-emission Champion “reputation.

In ensuring excellent fuel economy and ultra-low carbon dioxide emissions at the same time, a new generation of S 400 HYBRID also has exceptional dynamic performance: 3.5-liter gasoline engine provides 205 kW / 279 hp power, while its electric motor can produce 15 kW / 20 hp output power and 160 cattle • m starting torque. In the gasoline engine and electric motor common role, S 400 HYBRID integrated power output to 220 kW / 299 hp and maximum torque of 385 cattle integrated • m.

Mercedes – Benz S 400 HYBRID is based on the S 350 developed from, and in power transmission carried out extensive improvements. These improvements include a modified 3.5-liter V6 gasoline engine, a subsidiary of electromagnetic motors, one for the hybrid module is equipped with the 7G-TRONIC seven-speed automatic transmission, if necessary, operation and control of electronic components, transformers, as well as the high-voltage lithium-ion battery .

S 400 HYBRID in the next-generation compact hybrid module, the disk-type motor starters and generators play a dual role, not only helps to save fuel, but also by virtue of superior “accelerate” the effect of adding more drivers of vehicles fun. From the acceleration phase begins when the motor vehicle that is involved in power-assisted work, and for the six-cylinder gasoline engine delivers 160 cattle • m maximum additional torque to help the vehicle reach peak torque. In the motor and engine together, the driver can fully enjoy the S 400 HYBRID the excellent and smooth torque output and powerful acceleration.

In the braking process, the electric motors act as generators of the role, be able to recover the kinetic energy lost during braking and braking systems with internal combustion engines and conventional wheel braking system work closely together to achieve a smooth and gradual S 400 HYBRID system dynamic process. Recovered energy is stored in the engine compartment compact and efficient lithium-ion battery into, and when necessary re-use. The transmission process from the entire complex is located in the engine compartment into a high-performance electronic control components to manage.

S 400 HYBRID hybrid module also includes a convenient automatic ECO start-stop system. The vehicle is stopped (for example, a traffic signal), the system will automatically shut down the engine, until the re-start, the motor will restart the engine. Automatic start-stop system not only protects the S 400 HYBRID excellent fuel economy, but also due to re-start when the engine is extremely rapid, the maximum extent possible to reduce carbon dioxide emissions in the start-up phase in order to achieve protection of the environment.

New high-voltage lithium-ion battery: smaller, lighter, more power

In the S 400 HYBRID compact and highly efficient hybrid system modules, the core component is a new high-voltage lithium-ion battery. It is specially developed for automotive applications of lithium-ion batteries, is the world’s first mass production of motor vehicles used in lithium-ion batteries. Innovative lithium-ion batteries represent a higher energy density, the greater the power efficiency, smaller size, and lighter weight. Compared with conventional nickel-metal hydride batteries, lithium-ion battery capable of half the weight, to achieve more than three times the mileage of life. And its more compact design of further savings in the vehicle interior space.

In the S 400 HYBRID engine compartment, large-capacity lithium-ion battery replaces the conventional starter battery, not only for refrigeration compressor motors and electric stored energy, and by 12-volt DC transformer connected to the circuit board for the other standard electricity equipment (such as the headlamps and comfort equipment) to provide electricity. And because adoption of a compact and modular design principle, the whole hybrid system, the additional weight of only 75 kg. The newly designed battery system consists of the battery cell and lithium-ion battery pack, battery pack electronic monitoring systems, battery management features, high-strength shell, cooling gel, the cooling plate, the coolant supply, and high-voltage wiring formed.

There is no doubt that the success of lithium battery technology is inseparable from Mercedes – Benz decades of tireless efforts. In the last 30 years, Daimler for electric vehicles with more than 600 related patents, of which 230 patents and is closely related to lithium-ion technology.

Optimization engine thermal efficiency to reduce fuel consumption

In R & D process, the Mercedes – Benz S 400 HYBRID the engineer controls the variable valve 3.5-liter V6 petrol engine has been completely redesigned and improved. Engineers use Atkinson cycle principle, so that intake valve kept open slightly longer than the time of intake and compression cycle time between, thereby enhancing the engine’s thermal efficiency while reducing fuel consumption and untreated emissions. New cylinder head, different pistons and modified camshaft (with different camshaft control) the application of effective new generation of enhanced S 400 HYBRID the maximum output power (an increase of 5 kW / 7 hp), to reach the 205 kW / 279 horsepower, while reducing the actual fuel consumption.

Roads and highways in the city excellent fuel economy

In rural roads and highways, S 400 HYBRID demonstrated exceptional work efficiency: through the transfer of gasoline engine operating point to achieve lower fuel consumption rate. Starting torque output when the amazing results produced by the electric motor to promote not only made available to the driver was particularly excited about the strong sense of speed, but also reduces vehicle fuel consumption and emissions.

Enhance the efficiency of electric motors

Compact disc-type motor is installed in the engine and the 7G-TRONIC seven-speed automatic transmission, between in order to save more space and improve efficiency. S 400 HYBRID equipped with disc-type motor is actually a three-phase AC motor with a maximum power output of 15 kW / 20 hp, starting torque up to 160 N • m, the working voltage of 120 volts. It can be used as starters, but also can be used as generators, and in different situations of different auxiliary functions.

Advanced electric motor and the harmonious coexistence of the traditional internal combustion engine to give a new generation of S 400 HYBRID more technical advantages of reducing exhaust emissions and improve the agility of vehicles have had a very positive impact. In addition, the disc-type motor drive system can effectively suppress the torsional vibration of the work load, thus further reducing interior noise and vibration, in order to provide even more outstanding driving comfort.
“Accelerated” effect adds fun to drive

S 400 HYBRID hybrid module will not only help save fuel, but also by virtue of superior “acceleration” effect for the vehicle to add more fun to drive. From the acceleration phase begins when the motor vehicle that is involved in power-assisted work, and for the gasoline engine to provide 160 additional cattle • m maximum torque. Even in the engine at a very low speed when the S 400 HYBRID hybrid vehicle systems will enable a strong start, and quickly reached the limits of electronic speed limit. Thus, in any driving condition, the driver can be fully aware of the gasoline engine and electric motor join forces to create agile and strong driving force to accelerate, and without fear of any increase in fuel consumption.

S 400 HYBRID the maximum speed of 250 km / h (electronically limited), and only 7.2 seconds to complete from zero to 100 km / h acceleration. And S 350 (regular driver) has very good fuel consumption compared to, S 400 HYBRID the fuel consumption per 100 kilometers further reduce the 2.0-liter, carbon dioxide emissions reduced by 20% or so.

ECO automatic start-stop function: when the sliding stop to save fuel

S 400 HYBRID new generation of hybrid module using a very comfortable and efficient automatic ECO start-stop system, when the vehicle not more than 15 km / hour speed of sliding stop (for example, parking in the event of traffic lights before), Automatic Start-Stop the system will automatically shut down the engine until the vehicle started again. Once the driver depresses the accelerator pedal or release the brake pedal, the motor immediately to restart the engine, helping to save the parking of vehicles waiting for when the fuel consumption. In addition, because the engine is almost immediately re-start, start-up phase of the exhaust emissions will be substantially reduced at the same time, conventional engine start when the inevitable vibrations and bumps are also minimized.

Despite the opportunity to gasoline vehicles, low speed when the automatic shut down, but the power steering and automatic air conditioning thermostat will still be in the open state, because these two systems are driven by electric control. Even when necessary, Brake Assist system can also be run through the electrically operated. Of course, the automatic start-stop system is not in all cases, at low speed will automatically open. If the driver turning or parking operations in progress, S 400 HYBRID intelligent control system will temporarily lift the automatic start-stop function, so the driver be able to successfully complete the operation.

Brake energy recovery

When the S 400 HYBRID deceleration, the motor vehicle will act as the role of the generator, through the advanced “stop – start – energy recovery” process, the kinetic energy into electrical energy. Recovered energy is stored in a compact and efficient lithium-ion batteries are concerned, the rainy day.

Smooth continuity of energy through two stages, motor-assisted to upgrade the engine braking effect: the first stage, in the absence of a braking effect of the circumstances, the electric motor as a generator, ready to energy recovery. Once the driver depresses the brake pedal gently, who began the second phase. Generator output power will be with the brakes in proportion to the depth and growth. At this point, if the slam down hard on the brakes, the driver can clearly sensitive to the perceived engine braking caused by the resistance, while the energy generated when braking will be re-recycled.

S 400 HYBRID the braking system, after a slight braking effect will not be immediately reached, the feedback is relatively soft, only more effectively depresses the pedal, the hydraulic braking system will be activated quickly, and Intervention. This will not only generate more electricity, but also helps to reduce the hydraulic braking system wear. In order to take advantage of this can be as much as possible to create a “win-win” feature, Mercedes – Benz S 400 HYBRID engineers specially developed and equipped with a new brake pedal module, a new braking system.

Clever installation of electronic control devices

Car-specific electronic control unit to ensure the three-phase AC motors can be 120-volt high voltage DC circuit normal operation. Converter installed in the location of the original starter. At the same time, the system also be equipped with a separate low-temperature cooling circuit to avoid the electric components under the action of the current (current up to 150 amps) and a sustained manner.

Mercedes – Benz engineers transformer being installed in the right front cover, because this is more conducive to the 120-volt high-voltage circuit and 12 volts of energy conversion between the circuit board and can be in the standard battery power, through the cross-wiring for an emergency start. In order to ensure continued high levels of efficiency of power supply, transformer through low-temperature cooling circuit. 12-volt lead-acid batteries installed in the trunk, not only in standard electrical equipment for the vehicle to provide electricity, but also for the energy component of the monitoring system for high-voltage power supply. As the need to co-operation of lithium-ion batteries, lead-acid batteries than under normal circumstances should be smaller and lighter.

Technological maturity of the seven-speed automatic transmission

S 400 HYBRID already adopted the technology mature 7G-TRONIC seven-speed automatic transmission, and in accordance with the characteristics of a hybrid vehicle, upgrading the transmission management systems related software. Even if the engine is turned off, the newly developed auxiliary oil pump can also always ensure that the transmission lubrication.

S 400 HYBRID the complex transmission system consists of improved high-performance engine control module had to manage. The control module incorporates a number of useful features, and can according to different driving conditions (such as urban, rural, high-speed or low speed), supporting the driver to select the most appropriate mode of operation.

In the dashboard displays the status of hybrid

In the instrument panel-mounted with a separate display can be clearly demonstrated recovery of energy and battery charging status, to help the driver more intuitive hybrid power systems for monitoring the state from time to time.

Mercedes-Benz standards of safety concept beyond the seven security concept

Uphold the Mercedes – Benz tradition of excellence, Mercedes-Benz engineers always put the safety of the vehicles the highest status, and the many advantages that technology into mass production Mercedes-Benz cars, which including Daimler research for many years fuel cell technology. However, these advantages of technology’s biggest challenge is to ensure that the technology-related electrical components may be more reliable and secure. Here we advocate the safety of not only applies to the production, including the repair and maintenance staff during the workshop, but also consider the passengers in need of rescue after the accident when emergency services.

Thus, S 400 HYBRID the use of hybrid technology, the seven steps in the interpretation of the “security” concept of the highest level.

1. Step 1: S 400 HYBRID’s engineers have carried out all the lines color-coded to eliminate confusion; all the components are marked with safety instructions. This makes it easier to carry out quality checks on a regular basis.

2. Step 2: Adoption of the chunks of insulation material and a newly developed dedicated connectors for the entire system to provide comprehensive contact protection.

3. Step 3: includes the world’s first production model for the lithium-ion battery provides a set of well-coordinated security measures. This innovative battery installed in the high-strength steel shell into and carry out a reliable fixed. The battery pack can be effectively embedded in a special gel into the buffer of any bumps and impact. There are also vents with a safety film and a separate cooling loop device. Electronic control unit for continuous monitoring of internal security situation, and immediately in the event of any failure signal.

4. The fourth step of the security components, including separation of the battery port, to protect all high-voltage components independent fuse, as well as through continuous monitoring of multiple interlock switches. In other words, all the high-voltage components connected by the closed circuit. The event of failure, high-pressure system will automatically cut off.

5. Step 5: When the ignition switch to “off” or hybrid power system failure, the circuit breaker will be automatically activated, so that power high-voltage components. But this time the battery will continue to maintain a charge so that the engine can be reactivated at any time.
6. Step 6: In the event of an accident, the high-pressure system will completely cut off fraction of a second.

7. The seventh and final step, that is, the system for continuous short-circuit monitoring.

As a result of the compact and modular design principle, the entire system, the additional weight of only 75 kg (including the entire security system included). Mercedes – Benz of this pioneering technology has not only given the S 400 HYBRID exceptional driving performance, even widely applied in the near future to other Mercedes – Mercedes-Benz models in the. Equipped with a hybrid system of S 400 HYBRID the payload of 595 kilograms, and S 350 is basically the same.

Intelligent high-performance engine management systems can drive a different road conditions to respond quickly, and in the most optimal way of configure the vehicle drive system, so as to ensure the lowest possible fuel consumption and emissions.

• In the stationary gasoline engines are usually turned off, it would not consume fuel. By the power-driven refrigeration compressors and power steering pump can be air-conditioning and power steering systems to ensure uninterrupted operation. If necessary, and even Brake Assist system can also be run through the electric drives. So, S 400 HYBRID the comfort of the cessation of operation of the engine will not be affected. Crew will be like the car ride, like the other S-class models to enjoy relaxed, pleasant journey.

• S 400 HYBRID the start-up and speed up the show abnormal smooth and comfortable.
