2012 Mercedes Benz B Class
Considerably more spry and effective, but as well-situated and wide as always – the new Mercedes-Benz B-Class is a succeeder on all fronts. The fomite’s glower peak and more unsloped arse post cater for a get-go notion that hints at the constrict sports phaeton’s active certificate.
With a new four-cylinder gasoline locomotive featuring mastermind injectant and turbocharging, a new diesel, a new threefold clench contagion, a new manual transmittal and new assist systems, the front-wheel-drive car besides rings in a new technical era for contract cars from Mercedes-Benz. “No framework alteration in the story of Mercedes-Benz has e’er seen so many new developments introduced in one drop slide,” stresses Dr. Thomas Wb, Phallus of the Plug-in of Direction responsible Grouping Search and Mind of Maturation, Mercedes-Benz Cars. “Succeeding B-Class customers bequeath profit from this quantum bound in footing of cautionary low fire ingestion and CO2 emissions combined with drive pleasance, plenitude of infinite and the highest criterion of refuge that has e’er been usable therein course.”
The earth premier of the new B-Class (distance/breadth/meridian: 4359/1786/1557 millimetres) took berth at the 2011 Frankfurt Outside Drive Establish. It testament be qualification its way to European dealers in November 2011.
The exterior design: perfect space in a most attractive guise
The new B-Class is a distinctive Mercedes sports phaeton, oblation plenteousness of quad combined with telling dynamical execution as a hatchback bar. The feature lines of the outside figure betoken both of these attributes: forepart and behind mutant a width-emphasizing designing, with a all-inclusive, big grillwork and headlamps extending on the sides at the strawman patch the buns features a blanket bum windowpane, bikini poop lights with horizontally outgrowth wander and a prominent tailboard with low cargo sill.
2012 Mercedes-Benz B-Class
The new sportiness and the salient aeromechanics are peculiarly apparent in the slope business: the cowling flows seamlessly into the A-pillar and the cap occupation descends sleekly to the hit ceiling freebooter. The cap features a upset occupation which lends the fomite a yearner show. The marked rack arches runner by active lineament lines nether the beltline are a sportsmanlike reading of the flow pattern occupation from Mercedes-Benz. The backside border of the consistency features active position skirts which add a brush to the fomite’s appearing. Neat details such as the delicately intentional headlamps with the new spot constituent sustain the make’s patent agio credential which radiance done in the constrict section, too.
Outstanding aerodynamics: astounding cd value despite station wagon rear end
An great cart coefficient of cd = 0.26 places the new Mercedes-Benz B-Class at the vanguard of its commercialize section. Isolated from the flowing outside invention, legion optimization measures on points of item such as the airflow some the battlefront wheels, the underbelly figure and the chilling airflow are too essential tributary factors to this splendid sleek operation. Patents are pending for groundbreaking details such as the toothed cycle impish coddler. With the optional ECO Engineering box which leave be usable in due line, the Mercedes-Benz B-Class is tied on a par with the foremost sleek credential of the E-Class Coupé, attaining a hale coefficient of cd = 0.24 which is cypher curt of stunning for a fomite with a wagon buns.
New concept: lower overall height but more space inside
The new fomite conception underscores the active aspirations of the new Mercedes-Benz B-Class. The near prominent panorama is the rock-bottom stature: at 1557 millimetres, the new simulation crouches near cinque centimetres frown on the route than its predecessor. The seat height in relation to the road has also been reduced (minus 86 mm) in order to facilitate boarding, while maintaining a clear overview of the vehicle’s contours.
In response to requests from many customers, the sitting position is more upright, however. At the same time, the headroom has been further improved. With maximum headroom of 1047 mm at the front (without sliding roof), the B-Class is among the most spacious cars in its segment in this discipline, too. The ergonomically expedient more upright sitting position in combination with a lowering of the vehicle’s floor at the rear leads to a segment-leading degree of legroom (976 mm) which even surpasses that of the S- and E-Class.
The Mercedes-Benz B-Class is optionally available with the so-called EASY-VARIO-PLUS system. This enables simple reorganisation of the interior so as to enable the transportation of bulky items. Features of the EASY-VARIO-PLUS system include fore/aft adjustment of the rear seats by up to 140 millimetres (thereby increasing the luggage compartment volume from 488 to 666 litres) and a front passenger seat whose backrest can be folded forward onto the seat cushion.
The interior design: superior quality in a new dimension
High-quality materials and finely structured surfaces, stylish details, precision workmanship and a new spaciousness – the interior of the B-Class defines a whole new benchmark in the compact segment.
Many features have been the reserve of higher classes of vehicle to date and embody Mercedes-Benz’s special definition of quality and aesthetics. The dashboard is optionally available in ARTICO man-made leather finish and features stitching, for example. Four equipment packages (Chrome, Sports, Exclusive and Night package) enable individualisation according to personal tastes.
In the interior, the large, three-dimensional trim covering the entire dashboard first strikes the eye. It is available in four variants, covering a broad spectrum from modern through sporty to classic. Common to all versions is a high-class appeal combining an attractive look and feel with easy care and durability.
The three large round vents in the middle and their uniquely designed cruciform nozzles add a sporty attribute to the interior’s emotional design idiom. The display, which is available in two sizes (5.8- and 7-inch) appears to hover over the vents. With its stylish design – the trim frame with galvanised finish contrasting with the piano black of the front panel – and slender lines, the colour display (TFT) is a highly attractive feature in the cockpit.
The 3-spoke steering wheel, which always incorporates a silver chrome insert in the middle spoke, the instrument cluster with four analogue round dials and suspended pointers in 6 o’clock position and the seats with contrasting stitching underscore the sporty character.
The drive: designed for maximum efficiency
The new Mercedes-Benz B-Class features new petrol and diesel engines as well as new manual and automatic transmissions. All transmissions and engines have been developed in-house, with production taking place at the plants in Stuttgart-Untertürkheim and -Hedelfingen, Rastatt/Baden, Gaggenau/Baden and Kölleda/Thuringia. The simultaneous development process enabled perfect coordination of engines and transmissions, e.g. with regard to implementation of the ECO start/stop function which features as standard on all B-Class models.
Common features of the new drive systems are the use of state-of-the-art technologies for maximum efficiency, very smooth running, high tractive power right from low revs, sustainability in terms of impending emissions standards and low weight. For the purposes of transverse installation the engines, all of which are turbocharged, and the two transmissions are very compactly designed, providing the Mercedes-Benz B-Class with an exemplary small turning circle for a front-wheel drive vehicle of eleven metres. The engine and transmission suspension disposes of a four-point mounting system comprising engine mount, transmission mount and two self-aligning supports. This
suspension system has been designed specifically to meet the requirements of the high-torque engines with regard to minimum noise levels. The hydraulic damping integrated in the transmission mount is a key contributory factor to the exceptionally high ride comfort.
The new four-cylinder petrol engines (internal designation M270) mark the launch of a completely new engine series. The combustion process is based on the third-generation Mercedes-Benz direct injection system which was introduced last year with the BlueDIRECT V6 and V8 engines. Its use in the B-Class marks this technology’s debut in the compact segment. The new four-cylinder engines have been designed for both transverse and longitudinal installation. In the new B-Class they are initially available with a displacement of 1.6 litres, as the B 180 rated at 90 kW (122 hp) and the B 200 with an output of 115 kW (156 hp). Their maximum torque of 200 and 250 Nm respectively is available from an engine speed of 1250 rpm.
The new four-cylinder diesel engine is a further development of the OM651 deployed in the C- to the S-Class, a common rail direct-injection engine of the third generation. With its displacement scaled down to 1.8 litres and numerous optimised points of detail, this is the first time that the compression-ignition engine has been mounted transversely in a Mercedes-Benz car. The B 180 CDI generates 80 kW (109 hp) of power, while the B 200 CDI has an output of 100 kW (136 hp). The maximum torque stands at 250 Nm from 1400 rpm for the 80 kW variant and 300 Nm from 1600 rpm for the 100 kW variant.
Another Mercedes-Benz premiere is the new 7G-DCT dual clutch transmission in the Mercedes-Benz B-Class. This transmission is extremely compact, extremely variable with regard to adaptation of the engine speed thanks to seven gears, features an electric oil pump for start/stop capability, shifts gear without any interruptions in tractive power and combines the comfort of an automatic with the efficiency of a manual transmission.
The new 6-speed manual transmission designed along similarly compact lines as a three-shaft transmission is a close relative of the DCT. Extremely easy gear shifting, low shift forces, low internal friction and a low weight are among its most important characteristics.
The chassis and suspension: refined sportiness now for the sports tourer, too
“Fascinatingly agile” is the assessment of all test drivers who have put the new B-Class through its paces to date. Three factors are instrumental to the substantially enhanced dynamic performance in comparison to its predecessor, which does not come at the cost of any compromises on comfort: the lowered centre of gravity, the new four-link rear axle and the upgraded ESP® Electronic Stability Programme. A sports suspension is optionally available for further enhanced agility. The centre of gravity has been lowered by a further 20 mm and the suspension additionally features sports dampers with amplitude-selective damping and a Direct-Steer system to emphasize the car’s sporty character.
Steering: mechanical with electric assistance
The electromechanical steering of the B-Class has been redesigned. The electric motor of the servo assistance system is now located directly on the steering gear as a dual pinion EPS system, thereby optimising the package as a whole. A Direct-Steer system is available in combination with the sports package. The steering ratio becomes noticeably more direct at greater steering angles, enhancing the vehicle’s handling and agility substantially.
The electromechanical steering system makes an important contribution to the vehicle’s overall efficiency, as the steering assist function only requires energy when steering actually takes place.
New assistance and braking system reduces the risk of rear-end collisions
As a world first in the compact segment, the Mercedes-Benz B-Class features a radar-based collision warning system with adaptive Brake Assist as standard, which lowers the risk of rear-end collisions. The COLLISION PREVENTION ASSIST system outputs a visual and acoustic warning to alert a possibly distracted driver to identified obstacles, and prepares Brake Assist for the most precise possible braking response. This is initiated as soon as the driver emphatically operates the brake pedal.
In contrast to systems currently on the market in the compact class, the new COLLISION PREVENTION ASSIST brake assist feature is not merely a system intended to minimise minor damage in urban traffic. Rather, this innovative solution is aimed at protecting motorists from typical rear-end collisions in dangerous traffic situations. Mercedes-Benz expects the new safety system to have a significant positive effect on accident statistics.
The democratisation of safety also encompasses an array of other assistance systems which have been adopted into the B-Class from the larger model series. These include:
Premiere in the compact class: PRE-SAFE® available for the first time
The PRE-SAFE®preventive occupant protection system which features in the B-Class is available for the first time in this vehicle category. This represents a further step in the ongoing democratisation of this innovation, which was premiered in the S-Class in 2002. Core features of PRE-SAFE®are reversible belt tensioning, the closing of side windows and sliding sunroof in case of critical lateral dynamics and adjustment of the fully electric front passenger seat with memory function to an ideal position for maximum effectiveness of the restraint systems. PRE-SAFE®is always activated in response to critical longitudinal and lateral dynamics and may also be triggered upon intervention by certain assistance functions.
The scope of restraint facilities takes special account of the Mercedes-Benz B-Class’ use as a family car. Great importance has been attached to the safety of the rear occupants. Belt tensioners, belt-force limiters and belt height adjusters come as standard on the outer seats. Rear sidebags are optionally available. Integrated child seats and automatic child seat recognition are available as in the predecessor. Driver and co-driver are provided with new pelvis bags which are able to cover the pelvis and the entire upper part of the body. For head protection, a windowbag is fitted as standard.
COMAND Online multimedia system with internet access
Internet access, the convenient LINGUATRONIC voice control system, two navigation solutions tailored to different budgets, connection for mobile audio devices and an intuitive operating concept – the information and communication systems in the B-Class offers excellent user-friendliness and a superior level of functionality which has been the reserve of higher categories of vehicle to date. It is the new multimedia generation from Mercedes-Benz which delivers these standards. The operating concept featuring the turn/push control in front of the armrest and the control knob on the head unit is also familiar from other Mercedes model series.
The COMAND Online multimedia system offers internet access. Customers can either surf the web as they wish while the car is stationary or call up a Mercedes-Benz app whose particularly fast page loading and simple operation make it suitable for use while driving. Integrated apps include Google™ Local Search and Weather, and the facility for downloading a route which has previously been configured on a PC using Google Maps and transmitted to the car.
All set for the future: modular “Energy Space” concept
The modular “Energy Space” concept means that the new Mercedes-Benz B-Class is already designed to accommodate versions with an alternative drive: appropriate interfaces in the body shell enable the main floor panel to be modified and a step to be produced for the versions with alternative drive. An underfloor compartment covering part of the area under the rear bench seat offers space for alternative energy accumulators.
