This way the windscreen can be conveniently cleaned during the journey and with an open roof, without any of the water spraying into the vehicle interior. This is done by means of water guides integrated on both sides along the wiper blade - one on the left and one on the right - with minute laser-cut spraying holes. Via these channels, the innovative washer/wiper system always supplies washing fluid to the windscreen discreetly, precisely where it is needed: just in front of the wiper blade lip, according to the direction of movement of the wiper. In fact, the windscreen cleaning operation in the SL is still performed with washer fluid in the conventional manner. At the end of the day, a better cleaning effect is attained with up to half the amount of washer fluid. The MAGIC VISION CONTROL system works in accordance with the outside temperature, and it also automatically adapts the washer fluid quantity to the surrounding conditions. Mercedes-Benz controls the MAGIC VISION CONTROL system intelligently via three partly autonomous wash programs - for summer, for winter and for cabriolet driving. The new SL is the first vehicle to be equipped with the adaptive MAGIC VISION CONTROL wiper/washer system developed by Mercedes-Benz.
A head-up display, pedestrian detection, automated lane changing, lane keep assist, and stop-and-go adaptive cruise control with jam assist are also available. Even at higher speeds they are largely unaffected by any strong winds. Even at speeds of around 200 km/h the new SL offers extraordinarily high comfort during open-top motoring, setting new standards here. Maximum speed is rated at 250 km/h and, upon customer request, could reach 320-330 km/h if the electronic limitation is removed. It is only below a temperature of minus 20 degrees Celsius that the system makes use of the entire system’s maximum output, 270 watts. It covers the entire area behind the seat backrests as far as the upper edge of the head restraints. If the switch is operated, a trapezoidal frame is unfolded electrically, and when it reaches its final position a finely meshed textile fabric covers it, thus keeping the area behind the occupants virtually free of draughts. It emits preheated air from an orifice in the head restraint, and this warm air then wraps itself around the neck area of the occupants like an invisible scarf, therefore even making it possible to have the roof open when the temperature is cool, without any serious inconvenience.
The key to making this approach feasible is to have everything be cheap. Each of these vehicles are only a few years old with a limited number of miles recorded and have passed a rigorous certification process. When the vario-roof is closed and the side windows are lowered, a welcome breeze can be felt during hot weather. The A-pillar trim with a new shape features an aerodynamically and aeroacoustically tuned front edge and a water guide channel on the top edge prevent water from flowing from the windscreen to the side windows. The windscreen fitted with multi-layer foil also contributes towards the exemplarily low interior noise, combining a low component weight with good acoustic properties. It cleans the windscreen without the splash of water that usually briefly disrupts the driver’s field of view in the case of conventional windscreen washing systems - something that is especially unpleasant at night or when the sun is low in the sky and at high speeds.
An astonishing experience: the wiper blade glides over the badly soiled windscreen of the new SL, without a sign of a cleaning water jet, the occupants do not notice anything yet the windscreen is still cleaned! The holes are distributed along the entire length of the wiper blade, being more closely spaced towards the outside of the blade, where it sweeps a greater area, than closer in, where the area swept is smaller. A continuity test between the the engine block (earth) and the glow plug connector node will determine whether any of them are open circuit. It looks the V12 saga at Mercedes-AMG isn't over yet, as we found out the Affalterbach-based company will unleash the new SL 65 AMG beast early in April, at the NYIAS 2012. Little details are known at this moment, but the sports roadster should retain the current V12 twin-turbocharged engine with a total displacement of 6.0 litres.
