Mercedes-Benz S-Class 2005 issue. Increased attention okoloavtomobilnoy public to high-end machines are difficult to explain from the perspective of common sense, as these luxury limousines can not be evaluated in terms of practicality. But with the addition of the terms “most-most” – the most comfortable, the most expensive, most powerful, fastest – they are difficult to apply. After all, there will always be faster sports cars, cars from kutyure – expensive limousines and pokomfortabelnee.
Well, the best Executive car needs polbor parameters, which can only carry a few firms. According to experts, in the new car Mercedes-Benz S-Class W221 body with a optimum was achieved by a combination of superb electronics, beautiful interior and a unique active and passive safety.
The engine and suspension as compared to the previous generation of machines have not changed. But here’s electronics … Judge for yourself, the new Mercedes S-Class in the movement itself to carry out many operations that in the press it is not without reason called the four-wheel computer.
History of executive cars with the Mercedes brand dates back to the 1920s. In the prewar period, one of the most famous cars of this class was 770 Der Grosser Mercedes 1939 Release – official representative vehicle of Hitler’s Germany.
The first post-war car was the top-class Mercedes 300 Adenauer, so called by the name of the then German Chancellor Konrad Adenauer. The car was produced from 1951 to 1962 – it was her first time there were three-stage automatic transmission Borg-Wamer, mechanical fuel injection and variable rigidity of the rear suspension.

Simultaneously with “three hundred” produced the so-called “junior” Executive Sedan – the Mercedes 220 series W180 / 128 with a 2.2-liter row “six”. The car was produced until 1959, after which it was replaced by the Mercedes 220 series W111 / 112 with an entirely new monocoque body, the design of which were used were included then in vogue tail “fins”.
In 1963 came the famous “six hundredth”, which later became the protagonist of a series of anecdotes. It was a Mercedes-Benz 600 series W100 sedan and limousine services. The car had air suspension with manual or automatic adjustment of ground clearance, dual circuit hydraulic brakes are automatically deactivated when driving off the parking brake and seat electrically.
Along with the majestic “six hundredth” – the car of kings and presidents company produced cars Representation, were so to speak, it is easier – in 1965. The sedan rolled off the series W108 / 109, the appearance of which was created by the chief designer of the company, Paul Braque. Machines equipped with chetyrehfarnoy head optics, they were first established alternator Thermostat and fan drive.

In 1972 he replaced the W108 / 109 W116 series cars arrived, which are called the first official car Mercedes-Benz S-Class. The head machine of this series considered the Mercedes-Benz 6.9 450 CEL. The last digit in the name of the car consistent with engine capacity of 286-strong engine. The machine had hydropneumatic suspension and dry sump lubrication.
The next S-class car was the Mercedes-Benz W126 body with a release in 1979-one of the most beautiful and harmonious of cars of this series is equipped with enhanced safety systems (including at kosofrontalnyh bumps). The car had improved aerodynamics – the drag coefficient it was 0.36, and the front bumper had a spoiler reduces lift. Parent machine of this series Mercedes-Benz 560 SEL is equipped with hydropneumatic suspension.
The next S-class car was the Mercedes-Benz W140 series, manufactured from 1991 to 1998. It is on this car appeared dual ESP system, side glass, Brake Assist and Parktronic, as well as the first navigation system on the most powerful machine of this model first appeared S600 12 – cylinder engine.

And finally, in 1998 rolled off the Mercedes-Benz W220 series. The body of the car for the unconventional design of the company has been designed with the use of titanium and aluminum alloys – because of this the car was 300 kg lighter than its predecessor. By the way, many of the technical solutions underlying the “two hundred and twentieth” structure found its application in the new Mercedes-Benz S-Class W221 Series year of manufacture 2005. To start with the last turn to the suspension of the Mercedes-Benz. The front compared to the previous version upgraded – rack and pinion steering new “Mercy” has a variable transmission ratio, and the steering is able to artificially reproduce the “zero” position of the steering wheel. The very same suspension – independent, pneumatic, double wishbone. Rear – Independent, pneumatic, five aluminum levers
The car is equipped with a version of the S600 suspension relating to the categories Active Body Control (ABC) and is the only in the world of this active suspension, each rack which comprises a conventional twin-tube shock absorber spring and, in addition, the reference cylinder. Thanks to the powerful high-speed hydraulic system with a working pressure of 200 atmospheres, such racks are capable of changing its height while driving in real time, compensating for rolls and roll are increasing and comfortable ride.

Location in the cabin of eight airbags
The standard air suspension Airmatic compared to the previous version of the W220 upgraded – it has changed the settings Pneumoelements and made them thinner walls, which ANTOR group has increased and improved drivability.
Brakes – both front and zadnie – disc, ventilated, Hydraulic, with vacuum booster. For the first time in the S-kpassa machines applied electric rear drum parking brakes.
The new Mercedes S-Class can be equipped with one of the four power units. The most powerful S600 is a 5.5-liter 12-cylinder V-twin 517-horsepower gasoline engine with biturbonadduvom. The motor has a cam on one block in the heads, as well as three valves and two spark plugs per cylinder.
Several smaller capacity has 5.5-liter 388-strong / – shaped “eight”, which is representative of a new family of engines with four camshafts and four valves per cylinder. The engine provides dual variable valve timing, switchable at engine speed of 3,500 rev / min and the length of the intake tract swirl flaps. Motor is equipped with automatic transmission 7G-Tronic – it is able to switch immediately to the four transmission on the downlink, and the converter can be disabled on all gears.
The most “low-power” of gasoline powertrains – a V-shaped 3.5-liter “six” power of 272 hp Despite the fact that this engine is almost half “horses” than that of the V12 engine, its is enough for active driving.
And the last line of engines for the Mercedes-Benz S-Class – a 3-liter 6-cylinder V-twin turbo produces 235 hp, which has an enviable efficiency – fuel consumption in combined cycle the car with the engine of 8,4 l / 100 km. Although it appears that the economy is not the most important advantage of the car, the price is “off scale” for 100 thousand euros.
The front and rear of the passenger compartment
The body structure is widely used high-strength steels and aluminum alloys. Representatives of the company say that about half of the body elements – and this spars, side skirts, coloured inks, and so on – are made by hot forging of steel, which is three times stronger than the usual A, aluminum alloy molded hood, trunk lid, some elements of the doors and the rear wall salon. From the same material also made the front and rear cross member body. The floor panels have a bumpy surface – studies have shown that it increases the rigidity of the panels and the reduced level of vibration. By the way. compared with the previous model, the torsional rigidity has increased by 12 percent, and the length of welds sized doubled and reached 120 meters – is significantly increased operational strength of the body.
Aerodynamic studies have reduced Cl – coefficient of drag of a body Mercedes-Benz S-Class – up to 0.26, which made the car one of the most streamlined sedans should be noted that during the creation measures have been taken to reduce its wind noise – a highly sensitive apparatus bugged individual zone air flow, looking at the noise source. All this allowed to make the car one of the quietest in its class.
Mercedes-Benz Cars has always been the safest, but in “Two Hundred Twenty-first” safety systems have reached the highest level. So, the car has 11 sensors with which analyzes the type and severity of a collision, seat belts with pretensioners and load limiters, and eight airbags In addition, the body of the car is designed for efficient energy absorption during a crash. Machine safety has been thoroughly investigated in the course of carrying out crash tests on the very stringent US rules, when a car crashed into a barrier with a 30 percent overlap at 80 km / h, she stood with honor. By the way, these rules are much more severe in Europe.
In addition, the car has a lot of systems that enhance its safety. Thus, the machine is equipped with instrumentation radar cruise control Distronic Plus, which uses two radar – core operates at a frequency of 77 GHz and provides a range of 150 meters and sub 24 GHz serves a sector with a coverage angle of about 80 degrees at a distance of up to 30 meters. This system allows you to monitor the traffic at speeds from 0 to 200 km / h and gradually slow down the movement, if necessary, up to a complete stop. Distronic Plus is so effective that allows the driver to control the car, almost without touching the pedals. When driving in heavy traffic is sufficient to establish the limit of permissible speeds (for example, 0 – 110 km / h) and distance running ahead of the car (for example, 10 meters) – and the car begins to move independently of the car in front, speeding up, slowing down, stopping and re starting the movement.
A good help for the driver and the system will be the Night View Assist night vision device. It is necessary to activate it as instead of the speedometer (by the way, it is only a picture on the display) appears in the black and white space in front of the car – according to representatives of the company, a pedestrian on the highway side of the road is detected by night vision device at a distance greater than 50 meters, the one which reaches the light xenon headlights.
Incidentally, the lights on the “Two Hundred Twenty-first” in tight turns at low speeds can shine sideways, reducing the risk of collision with an obstacle, compared with a machine equipped with a traditional head optics. When driving at high speed on suburban routes headlights follow the steering wheel, helping the driver to detect danger earlier.
In order to form an impression of comfort, a new car, enough to list the functions that can perform the normal driving seat. Start, perhaps, it should be with this elektroregulirovok multicontour seat – with their help, it provides the most comfortable fit and, if necessary (if the machine is used by several drivers) stores configuration found. In the long flight tired driver can select one of four modes of massage – with seven special pneumatic chambers in the back of the chair begin to knead stiff muscles. Hot? Six built-in the case of fans four in a bed, and two in the back – will heat imperceptible. In active mode, the chair responds to steering, increasing the backwater side when cornering.
Incidentally, the rear seats can also change the angle of the backrest, cushion height and also have a built-in massage device. For a surcharge, television screens can be integrated in the headrests of the front seats.
The “two hundred and twenty First” – a new four-zone climate system. Power conditioning unit is 8.8 kW, heater – 9.7 kW. The system includes 15 electric drive mechanisms dampers and the only fan. The surcharge rear of the cabin can be equipped with an additional fan.
While the new W221 is offered to customers only with the V6 and V8 engines in the optimal configuration: ABS function to prevent rolling, tire pressure sensors electromechanical parking brake, the boot lid with the electric drive and stepless door latches. Of course, this is not all, in the optional equipment list and have a night vision system, a rearview camera and a lot more. Well, the price … For a standard Mercedes-Benz S350 asking 82,000 euros for the long wheelbase S500L – 110,000 euros. And, of course, all the additional options for extra money.
