Merecedes -Benz S 350 BlueTEC (since 2013)
The Mercedes -Benz 222 series, the tenth generation of the resident in the Upper Class S-Class of the German car manufacturer Mercedes -Benz represents the world premiere took place in Hamburg on 15 May 2013. Production started on 12 June, during the launch on July 20 was fixed.
The sedan series 222 is the successor to the 221 series. The coupe will replace the CL-Class from spring 2014 and will be referred to henceforth as the S -Class Coupe.
The starting price of the Series 222 is to launch at around 80,000 euros.
The Series 222 is based on its predecessor, the 221 series, shares with this the bottom group and also its type approval ( Carry -Over Principle). Thus, it is formally considered in the new model is a version of the Series 221 The acquisition of the type approval is also legally relevant as there continues to R134a can be used, that is not authorized for cars, carried out whose type approval after 2011. Thus, the safety aspects controversial, but less climate damaging refrigerants could be R1234yf avoided. At the time of launch R1234yf refrigerant is the only technically feasible alternative for new type approvals. The wheelbases are identical with those of the previous model due to the acquisition of the floor assembly. The developers emphasize that in contrast to previous generations of this model, the long-wheelbase (V 222) was the original model of development, of which the normal version (W 222) was derived. The reason is the diminishing importance of upper class sedans in Europe by lower sales volumes. At the same time grow the American and the Chinese market, which is at the beginning of the second decade of the 2000s even become the most important of the S-Class sales. In these markets, the long-wheelbase versions are sold as chauffeured limos priority, so that the focus of development was on the long-wheelbase version.
After cessation of production of the previously settled on the S-Class Maybach saloons, there will be an extra long version alongside the existing wheelbases, the internal X 222 is called. In addition, the S-Class is generally located slightly higher.
Development and innovation
In the tenth generation of the S - class engineers focused again pay special attention to the comfort, security and processing. Noise, vibration, vibration and glare to have been greatly reduced. Odors and an optimal climate were also at the forefront of development. Thus, in the series 222, the perfume atomiser from the Maybach is available. To increase the ease of use, use was made of anthropometry, the science of human body measurements. Furthermore, hundreds of customers have been used to improve the operation in a newly developed simulator. The noise comfort to have been improved by an aerodynamic body design, the value is given by 0.24, which represents the best value among all luxury saloons. The material quality and processing should be based on the models of Bentley and Rolls- Royce now.
On the part of the art series features 222 two LCD screens with a diagonal of 12.3 inches each. While on the left screen, a digital speedometer is projected over the right of the screen the information of the Comand system are reproduced. As the world's first vehicle no more light bulbs are installed in the S-Class. These were replaced with 190 LEDs. Through the use of LEDs in place of the existing incandescent lamps, the power consumption should be reduced to a quarter. While the newly developed LED beam needs 34 watts, 120 watts and for xenon light 84 watts needed for tungsten halogen lamps. Through the repetitive use of full LED headlights, the carbon dioxide emissions can be reduced by around 2.1 grams per kilometer.
Furthermore, the series receives 222 a variety of newly developed assistance systems, the long-distance, short-range and ( multigrade ) radar, stereo cameras, infrared video and ultrasonic sensors are based network among themselves, are not only in the front area, but also the rear and monitor the lateral portions of the vehicle and thus provide a 360 - degree view. Thus, on request, a wrong-way driver warning system that has been developed in collaboration with Continental AG, available. It is produced by a camera in the upper region of the windscreen, the respective signs seen to then initiate warning signals in two stages, if necessary. At the beginning carried out visual and audible warnings, the ride is still continued, the straps are tightened several times briefly, the steering wheel starts to vibrate and the vehicle begins with short autononem stunts. The Lane Keeping Assist has been developed and is now working actively so that oncoming traffic and vehicles are detected on the adjacent track and the system prevents leaving the track by one sided braking intervention. The security system Pre-Safe was well developed, can be found in the third generation in the Series 222 and again from now recognizes pedestrians. To avoid an accident, the so-called Pre-Safe brake slows down to a speed of 50 km / h fully autonomous. The system was further expanded to include Pre-Safe Plus that detects an impending rear-end collision, so that secondary accidents with the vehicle ahead can be prevented because the stationary vehicle is braked in a collision. Also Distronic Plus has evolved and expanded to include a steering assist, so that the vehicle autonomously complete traffic jam trips and keep track own and correct if necessary can.
Another innovation in the automotive industry is the Active buckle in the rear seats, which extends to seven inches when opening the rear doors. With a recognized risk the belt buckles are also lowered by four inches and the straps tightened so to fix the passengers stronger. A so-called Beltbag on the rear seats to reduce the risk of injury further. It is an inflatable up to three times the width of the strap.
A unique feature is the active suspension Magic Body Control, which detects bumps in the road ahead using cameras and sensors and adjusts the dampers so that driving irritations are completely suppressed. It is based on the Active Body Control Fahrkwerk from the previous series. The measurement accuracy of the stereo camera is between one and two millimeters and includes five to 15 meters of the insert before the vehicle range. In this way, body movements are to be compensated. The system works during the day in good visibility conditions and uncovered pavement (not wet ) and up to a speed of 130 km / h
The seats have been redesigned and are optionally available now over 14 air cushions per seat, which are needed to realize the six different massage programs or to warm specific areas. New is also the sound system from the German manufacturer Burmester, which was previously only available in high-priced brand vehicles Porsche and Bugatti. By Daimler is propagated, using 24 speakers - including three in the vehicle roof - to have reached a 3D sound. The appropriate boxes are mounted directly under the sheet, to use the cavities as resonators can.
At launch three engines to choose from, including a gasoline engine, a gasoline engine with an electric motor (gasoline hybrid ) and one diesel. The petrol model in S 500 (M 278) is known from its predecessor and has displacement of 4.7 liters and an output of 335 kW ( 455 hp ). The gasoline hybrid in the S 400 HYBRID is based on the 3.5 -liter V6 Series M 276 The system performance is specified with 225 kW (306 hp). The S 350 BlueTEC diesel engine has been taken easily optimized from the 221 series. The output remains unchanged at 190 kW (258 hp). All models are coupled at the beginning of the 7- speed automatic transmission 7G- Tronic Plus with start -stop system and are driven by the rear wheels.
In the fall, the engine range for the all-wheel drive S 500 4MATIC and S 63 AMG with 430 kW end of March 2014 was extended ( 585 PS), follow the one the 12-cylinder flagship models S 600 L and S 65 AMG L, on the other hand two other hybrid models S 500 hYBRID PLUS, in which it is a gasoline hybrid, and S 300 BlueTEC hYBRID, which is based on the 2.1 -liter OM 651 diesel engine and an electric motor with 20 kW ( 27 hp ) was combined performance. The overall performance thus amounts to 170 kW (231 hp). In addition, the all-wheel drive 4MATIC from March 2014 is also available for the S 350 BlueTEC. 2014 developed by Mercedes -Benz even 9- speed automatic transmission 9G -Tronic will eventually be introduced.
