<< Prev Page 2 of 2  The exterior design of the SL 43 differs in individual details from the two eight-cylinder models. For example, it has differentiated front and rear aprons as well as round instead of angular double tailpipe trim. The defining features of the SL body design include the long wheelbase, the short overhangs, the long bonnet, the passenger compartment set further back with steeply raked windscreen, and the powerful rear end. This results in the typical SL proportions. They give the roadster its powerful, dynamic appearance - together with the voluminously modelled wheel arches and the large light-alloy wheels that are flush with the outer skin. The SL 43 runs on 19-inch light-alloy wheels as standard. In addition, the same range as for the eight-cylinder models is available as an option: aerodynamically optimised light-alloy wheels with diameters of 20 or 21 inches, which reduce air resistance through low turbulence. Particularly sophisticated are 20-inch wheels with plastic aero rings that save additional weight.A technical highlight for improving aerodynamics is the AIRPANEL active air control system. The horizontal louvres behind the upper air intake are electronically controlled and can be opened and closed with actuator motors. In this way, the airflow is directed according to demand, thus improving aerodynamic performance. Normally the louvres are closed - even at top speed. This position reduces air resistance. Only once predefined components have reached certain temperatures and the demand for cooling air is particularly high do the louvres open and allow the maximum amount of cooling air to flow to the heat exchangers. This calls for highly intelligent and fast control. The same applies to another active component of the aerodynamics: the retractable rear spoiler seamlessly integrated into the vehicle profile. It changes its position depending on the driving status. In doing so, the control software takes into account numerous parameters: It factors the driving speed, the longitudinal and lateral acceleration and the steering speed into the calculation. The spoiler assumes five different angle settings from 80 km/h to either optimise the handling stability or reduce drag. The optional Aerodynamics Package for the Mercedes-AMG SL 43 includes larger flics on the front and rear bumpers and a larger rear diffuser. This improves both downforce and aerodynamic drag even further. The modified speed thresholds of the rear spoiler and its steeper angle of attack of 26.5 degrees (instead of 22 degrees) in the Dynamic position also contribute to this. The sportier positioning of the new SL also suggested the decision for an electric soft top instead of the previous metal vario-roof. The 21-kilogram reduction in weight and the resulting lower centre of gravity have a positive effect on driving dynamics and handling. The Z-fold saves space and weight, and makes it possible to dispense with a conventional soft-top compartment cover. The front header bow ensures that the open soft top is flush in its final position. At the same time, the developers were faced with the task of maintaining the high suitability for everyday use and the exemplary quiet-running. The three-layer design consists of a tightly stretched outer shell, a precisely finished roof liner and an acoustic mat made of high-quality 450 g/m² PES fleece inserted in between. Opening and closing takes only about 15 seconds and is possible up to a speed of 60 km/h. The soft top is operated using the switch panel in the centre console or the multimedia touch screen, on which an animation shows how the process is progressing. The interior of the Mercedes-AMG SL 43 also features an exciting combination of analogue geometry and the digital world - known as "hyperanalogue". This is exemplified by the fully digital instrument cluster, which is integrated into a three-dimensional visor. The standard MBUX infotainment system offers a choice of several specific display styles and different modes. The symmetrical instrument panel is designed as a powerful wing and structured into an upper and lower section. The highlight are the four galvanised turbine nozzles. Their surfaces merge into the instrument panel in the form of powerful power domes. The lower section of the instrument panel evolves fluidly from the centre console, seamlessly connecting the two elements. Despite symmetry, the cockpit design creates a clear focus on the driver: The high-resolution 12.3-inch LCD screen of the instrument cluster is not designed to be free-standing, but integrated into a high-tech visor that prevents reflections caused by sunlight. In order to avoid disturbing light reflections caused by different sun positions when the soft top is open, the tilt of the touch screen on the centre console can also be electrically adjusted from 12 degrees to 32 degrees. The latest generation MBUX (Mercedes-Benz User Experience) is intuitive to operate and capable of learning. It offers a host of functional content and the operating structure of the second-generation MBUX system, which debuted in the new Mercedes-Benz S-Class. In the SL, extensive AMG-specific content in five display styles is added. Exclusive menu items such as "AMG Performance" or "AMG TRACK PACE" also emphasise the sporty character. The SL 43 is equipped as standard with a wide range of electrically and manually adjustable luxury seats in a combination of ARTICO man-made leather and fabric. Seat covers in leather, NAPPA leather and NAPPA AMG leather are optionally available, as are AMG sports seats and AMG Performance seats with their sculptural design. The optionally available upholstery in MANUFAKTUR macchiato beige/titanium grey or in MANUFAKTUR truffle brown/black ensures a particularly exclusive touch. The AMG Performance seats can also be upholstered in a combination of nappa leather and DINAMICA microfibre with yellow or red decorative topstitching. In addition to the standard high-gloss black, the trim elements and centre console are also available in aluminium or carbon and in MANUFAKTUR chrome black. The AMG Performance steering wheel with optional steering wheel heater is available in nappa leather and nappa leather/MICROCUT microfibre. As standard, the SL 43 is equipped with a newly developed AMG RIDE CONTROL steel suspension with particularly powerful aluminium shock absorbers and lightweight coil springs. The new SL is the first production vehicle ever from Mercedes-AMG to feature a multi-link front axle with five links arranged entirely within the rim. This significantly improves the kinematics. At the rear axle, a 5-link design likewise controls the wheels. To reduce unsprung masses, all suspension links, steering knuckles and wheel carriers on the front and rear axles of the new SL are made of forged aluminium. The multi-link concept controls each wheel with the least amount of elastic movement. The high camber and track stability not only enables high cornering speeds, it also provides the driver with optimal road contact at the high cornering limit. This is reflected in excellent lateral dynamics and driving stability at high speeds as well as in the good-natured reaction to external influences such as crosswinds, bumps or jumps in friction coefficients. The lightweight coil springs are a new development: special tempering allowed their weight to be lowered without reducing their performance. In the manufacturing process, the spring pad is glued onto the spring for the first time. This firm connection prevents wear and tear caused by dirt such as sand over the course of a vehicle's life. The spring does not corrode over the life cycle, and the maximum component load can consequently be increased at less weight. This saves around 0.2 kilograms per spring. Another lightweight construction measure concerns the torsion bar stabilisers on the front and rear axles of the SL 43. Thanks to a variable wall thickness, their weight can be reduced. The maximum wall thickness is now only used where it is required due to the maximum load, in this case in the area of the rubber mounts. The latest generation of AMG adaptive adjustable damping is available as an option for the SL 43. The suspension control unit uses data analysis - including acceleration and wheel travel sensors - to adjust the damping force for each wheel in a few milliseconds to suit the situation. The driver can pre-select the basic set-up via the AMG DYNAMIC SELECT driving modes: at the touch of a button, the handling characteristics change, for example, from full dynamics in "Sport+" mode to smooth cruising in the "Comfort" setting. In addition, the tuning can be adjusted in three stages independently of the driving modes via a dedicated button. The newly developed AMG high-performance composite brake system guarantees excellent deceleration values and precise control. It impresses with short braking distances, sensitive response and last but not least with high stability and durability - even under extreme stress. Comfort functions include Hill Start Assist as well as pre-filling and dry braking in wet conditions. When the ignition is switched off and the vehicle is stationary, the parking position "P" is also activated. When starting off, the electric parking brake is released automatically. The composite brake discs are particularly light: Driving dynamics and turn-in behaviour benefit from the reduced unsprung masses. Brake disc (made of cast steel) and brake disc pot (made of aluminium) are now connected with special pins. This design saves space, which is used for even better brake cooling. The directional perforation is also new: In addition to the weight saving and better heat dissipation, this solution scores points with a faster response in wet conditions as well as better pad cleaning after braking. The Mercedes-AMG SL 43 can be equipped with active rear-axle steering (HAL) as an option. Depending on the speed, the rear wheels steer either in the opposite direction (up to 100 km/h) or in the same direction (faster than 100 km/h) as the front wheels. The system thus enables both agile and stable driving characteristics. The front-wheel steering ratio is more direct, making it easier to steer the vehicle at the limit with less steering effort. The five AMG DYNAMIC SELECT driving modes "Slippery", "Comfort", "Sport", "Sport +" and "Individual", as well as the "RACE" mode included in the optional AMG DYNAMIC PLUS Package, enable a wide spread of vehicle characteristics from comfortable to dynamic. The distinct driving modes offer an individual driving experience, precisely tailored to different driving conditions. As a feature of the AMG DYNAMIC SELECT driving modes, the SL models also feature AMG DYNAMICS. This integrated vehicle dynamics control expands the stabilising functions of ESP® with interventions that enhance agility in the steering characteristic and in ESP® additional functions. When cornering at speed, for example, brief braking intervention at the inner rear wheel generates a defined yawing moment around the vertical axis for responsive and precise turn-in. With the details of its extensive standard equipment as well as many additional options available, the Mercedes-AMG SL 43 offers a broad individualisation spectrum for a wide range of customer wishes - from sporty and dynamic to luxuriously elegant. This includes twelve paint finishes including the two exclusive SL colours hyper blue metallic and MANUFAKTUR monza grey magno, three roof colour variants and several new wheel designs. Three exterior design packages are available to sharpen the look further and make it more elegant or more dynamic. << Prev Page 2 of 2 |
