The ceramic system protects itself against overheating by monitoring its own surface temperature and reducing the power consumption automatically when required. Nevertheless, the heating effect remains constant.AIRSCARF?can be started at the push of a button. At speeds of up to 120 km/h, a control unit calculates the ideal warm air distribution automatically ? depending on the interior and exterior temperature, on whether the soft top is open or closed, and on the vehicle speed. Above this speed, the system operates on a constant setting. Furthermore, the driver and front passenger can set the speed of the radial fan and, therefore, the heat supply, to any one of three levels, all at the push of a button on the centre console. The powerful AIRSCARF?system produces up to 27.4 kilograms of warm air per hour.Shots taken using the thermography camera show how effectively the patented AIRSCARF?system operates at low outside temperatures in winter. Costing some ? 50,000, the special camera enables people to see that which usually remains invisible: the heat radiated by persons or objects.The principle at work here is as follows: at temperatures above absolute zero (i.e. minus 273 degrees Celsius), all objects essentially radiate heat ? even ice cubes or snowballs. This thermal energy is infrared light with a wavelength that the human eye cannot perceive. The higher the temperature of the object, the more intense its infrared radiation.
The AIRSCARF?tests conducted by the Mercedes engineers using the thermography camera are based on this fundamental physical principle. The camera's highly sensitive lens scans the driver, the seat backrest and parts of the interior, making heat visible: zones with high heat radiation appear in red, violet and white on the monitor, while cooler areas are coloured green or yellow. The dark blue and black areas, on the other hand, are the areas where the temperature is at its lowest. The thermograms clearly show where a large, wide sea of warm air is produced in the E-Class Cabriolet.In addition, testers wear special measuring shirts during the tests. These garments are equipped with a total of 14 measuring points distributed around the throat, neck and shoulder areas, which can measure the various temperatures individually, allowing the distribution of warm air to be analysed.When developing the AIRSCARFDesignThe stuff of which cabriolet dreams are made?
Classic: elegant cabriolet silhouette thanks to soft top? Family ties: twin-headlamp face and muscular stature? High quality: refined interior surfaces
From the very first drawings onwards, the Mercedes designers were sure of one thing: only a classic fabric soft top can convey a stylistically pure cabriolet feeling. Consequently, the new E-Class Cabriolet, which combines an elegant appearance with a high awareness of tradition, had to have a soft top. Viewed from the side, the two-door model therefore offers an enticing mix of clear proportions and a flawless cabriolet silhouette, including a long bonnet, wide doors, a high beltline with elongated side windows, a lowered soft top contour, and a short rear overhang. This look is complemented by the powerfully muscular section in the side wall at the rear axle and a slender C-pillar.As well as sharing family traits with the other E-Class models, the new Cabriolet has its own, distinct identity characterised by a greater sense of passion. The arrow shape of the entire front section from front bumper to radiator grille to
bonnet, the more extreme interpretation of the twin headlamp face and its more sinewy build give it a racier and more dynamic presence. At the same time, the close family ties with the E-Class Coup? are clearly apparent.
The powerful styling accentuates the sleek, flowing lines
A special characteristic of the contemporary Mercedes design idiom is the creative interplay of edges and surfaces. Taut, sharply defined lines, which grow out of surfaces organically and disappear into them again equally gently, structure the sides of the Cabriolet. The high shoulderline, a prominent, downward-pointing feature line (another contemporary Mercedes styling element) and a second structuring line delimit the sensitively sculpted surfaces. Alternately concave and convex, these create a sleek yet sharply defined flow of lines which creates a fascinating interplay of reflected incident light.
Arrow-shaped front and dominant radiator grille
From the front bumper to the radiator grille to the bonnet, the pronounced arrow shape of the front section emphasises the sporty character of the Cabriolet. A
central crease in the bonnet picks up this shape and trails back towards the windscreen. A wide, upright radiator grille with two louvres, striking chrome strips, a powerful chrome surround and the central star testifies to status and self-assurance in time-honoured Mercedes style. The grille makes an effortlessly superior, expressive statement of the brand's identity.The traditional twin headlamp face is based on that of the new E-Class Saloon, but has its own identity. Longer, more sharply inclined and flatter, the headlamps have a more dynamic look which is unmistakable. With their elaborate, high-tech interior and quadrant-shaped indicators, they add a sparkling finishing touch to the front of the vehicle.A distinctive front apron with large air intakes gives the vehicle a strong, powerful presence. Two vertical struts in the front apron provide visual support for the radiator grille and give it a substantial formal base. Depending on the model version, the bumper houses either the fog lamps or the daytime driving lights and fog lamps side by side. In the versions with bi-xenon headlamps, L-shaped daytime driving lights based on LED technology give the vehicle an expressive look.
Powerful rear with innovative lights
"Powerful and not afraid to show it" could be the motto for the rear section of the new E-Class Cabriolet: the rear wings spanning the rear axle are sculpted to create a powerful, muscular form which visually enhances the vehicle's width. The distinctive feature line ? a characteristic Mercedes styling element ? is continued skilfully around the back of the vehicle and into the tail lights, thereby forming a link between front and rear.The LED tail lights are split and extend from the boot lid far into the side wall. In so doing, they emphasise the width and dynamism of the vehicle. Their innovative lighting technology is particularly noteworthy. An LED background lighting system provides indirect illumination of the three-dimensional back cavity in both light units and in this way sets the basic background lighting tone. Twin light arrays with twin LED light guides stand out against the background lighting. These light arrays accommodate the tail lights and the brake lights, while the reversing lights and an additional LED fog lamp are integrated in the boot lid light units.The narrowness of the gap between the light unit on the boot lid and that on the side wall, as well as the extremely precise bevelling of the adjacent light lenses allows light transmission between the two sections. As a result, the night design of the new Cabriolet maintains the perceived width and harmonious appearance of the rear section.
Interior with sporty lines and high perceived value
In the interior, the designers have continued the taut, sporty design idiom of the exterior. The compelling interplay of surfaces and clearly defined lines creates an interior whose elegance and high perceived value are evocative of modern architecture. The cockpit is structured horizontally with a dark upper section in order to avoid unwanted reflections. Interior appointments in two colours ? in keeping with the logic of the two-level structure ? create intriguing contrasts.With its sporty look and feel, the cockpit design is clearly in keeping with the agile character of the new Cabriolet. The instrument cluster with five tubes for the dials and a central display has a slender look, while the dials themselves are clearly laid out and have high-quality chrome surrounds as well as a silver backing for the scales. The background colour of the dashboard is silver or black, depending on the choice of trim elements. The three-spoke steering wheel with multifunction buttons is available in a number of different versions and colours in order to match the interior appointments.Next to the instrument cluster ? and therefore in the primary field of vision of the driver and front passenger ? is the display area for the control and display system for the radio, navigation system and other functions. The system is operated by means of a rotary and push-action Controller which falls conveniently to hand in front of the asymmetrically split armrest between the front seats. This armrest also serves as a handrest when operating the Controller. This is also where the control buttons for the soft top and AIRCAP?are to be found.The horizontally structured dashboard flows into a centre console with a dynamic, arrow-shape where the air-conditioner control unit is to be found along with other features.
Sporty individual seats for the rear passengers, too
The new E-Class Cabriolet is an out-and-out four-seater and also has sportily
designed individual seats in the rear. The front integral seats with pronounced, faceted side bolsters and transverse piping on the seat cushion have a light, contemporary look and immediately create a distinctly sporty impression while offering excellent seating comfort. Another notable characteristic of the seats is the high-quality, hand-stitched workmanship featuring discreet flat-felled seams. Further highlights include the audio system's loudspeakers housed in the soft top compartment cover, which add an extra visual touch, especially when the roof is open.
Fine materialsThe whole interior is dominated by pleasing surface finishes. Trim elements made from valuable, authentic materials emphasise the high-quality of the new Cabriolet. The sporty two-door model is equipped as standard with brushed aluminium trim elements with a sporty spin finish. Customers can also choose from fine woods: burr walnut, high-gloss black ash or the graphic linearity of pine. In all cases, the trim elements have a thin chrome strip along their upper edge.The roofExemplary quiet-running?
Quiet: acoustic soft top as standard for all versions? Safe: exceptional all-round visibility thanks to slender C-pillars? Hard-wearing: soft top can be put through an automatic car wash without hesitation
Thanks to its acoustic soft top, fitted as standard, the E-Class Cabriolet has one of the quietest interiors in the segment for four-seater premium cabriolets with a fabric roof. The soft top's exceptionally high-quality insulation brings about a clearly noticeable reduction in the interior noise level compared to conventional fabric soft tops. Exterior noise caused by other vehicles and wind noise are therefore absorbed more effectively. On the road, the difference is audible from speeds of just 80 km/h, for example when driving through a tunnel or overtaking a convoy of trucks. At higher speeds, the benefits of the acoustic soft top are even more tangible. For instance, it is possible to have a perfectly normal phone conversation in hands-free mode even when travelling at a speed of over 200 km/h.Three new developments enabled the Mercedes-Benz engineers to reduce the interior noise level substantially: the outer fabric coating on the soft top has been acoustically optimised, while a butyl layer in place of the previous neoprene layer on the inside acts as a water barrier. Finally, the intermediate felt layer is structured differently to that of the previous model. This layer also ensures that the elegant silhouette is not disturbed by bows visible from outside.The E-Class Cabriolet likewise sets new standards when it comes to all-round visibility ? important for both looks and safety. The soft top fabric in the C-pillar area is extremely slender thanks to the sophisticated kinematics of the rear windscreen which, rather than being rigidly welded in place, moves out of the soft top fabric when the roof is opened and closed. Special water pockets prevent moisture ingress at the sides.Of course, the soft top itself is also waterproof and windproof. Plus it can be put through an automatic car wash without any hesitation. With a total thickness of 23.5 millimetres, the fabric soft top offers excellent thermal insulation, meaning that the E-Class Cabriolet is also ideal for use in winter. The heated rear windscreen is made of glass and is therefore scratchproof. The soft top is available in black, blue or beige.Supreme ease of use was a key criterion when developing the soft top, which is hydraulically operated by means of seven cylinders pressurised by an electric pump. Fully automatic opening and closing of the roof takes around 20 seconds and is possible at speeds of up to 40 km/h. A pull on the control element on the centre tunnel is all it takes. Alternatively, the roof can be controlled remotely by pressing a button on the key. The soft top engages automatically at the front roof crossmember.The soft top is stowed in a special compartment behind the rear panel. A retractable cover separates the soft top compartment from the boot area; it must be closed in order to close the soft top. If the roof is to remain closed, the cover can be slid rearwards, in which case the boot capacity is increased by 90 litres to 390 litres.Differences between the exterior and interior air pressures can cause a ballooning effect on certain cabriolet models when travelling at high speed. But not in the case of the Mercedes-Benz E-Class Cabriolet: a special zip fastener is used to fasten the soft top firmly to the frame over all three bows. This fastening and the short fabric lengths between the supports are effective at preventing ballooning of the roof when travelling at high speed. Sophisticated test equipment was used to measure and document this effect during the road-testing phase.The cabriolet specialists at Mercedes-Benz also attach great importance to the durability of the fabric soft top. Hence the roof is designed for 20,000 load cycles ? the highest figure in this competitive environment ? equivalent to opening and closing the soft top once on every day of the year for over 25 years. In the unlikely event of the fully automatic closing mechanism failing, for example due to a flat battery, Mercedes-Benz has seen to it that E-Class Cabriolet drivers will not be left in the rain, since the hydraulic system can be depressurised quickly, enabling the soft top to be closed and locked by hand
