Body: Sporty rigidity and safety

May 9, 2013
The Coupé and Cabriolet bodies have long since proven their qualities when it comes to safety, rigidity and comfort. On top of this, they offer outstanding aerodynamics and, thanks to innovative production and quality assurance processes, consistently high quality.  
Since the basis of the body has remained the same, the E-Class Coupé and Cabriolet continue to boast the same outstanding characteristics. These include: 
  • very rigid and strong occupant cell using an intelligent material mix consisting of sheet steel combined with a high proportion of high-strength and ultra-high-strength sheet steel and aluminium detachable body parts
  • comprehensive deformation zones in the front and rear areas
  • lightweight construction - bonnet, wings and boot lid made of aluminium
  • excellent ease of repair thanks to removable front and rear modules  
Compared to the Coupé, the components and load-bearing structures have been further reinforced on the Cabriolet, ensuring high levels of structural safety despite the absence of a stabilising fixed roof structure. The additional measures include:  
  • Cabriolet-specific reinforcement of occupant cell in vicinity of the floor assembly and sidewalls
  • cross-bracing in vicinity of the sidewalls and rear-seat cross member, as well as side members with extra reinforcement compared to the E‑Class Coupé
  • weight-saving extruded aluminium section between the A-pillars used as cockpit cross member
  • Cabriolet-specific reinforcement of doors
  • extra brace between spring tower and cross member  
Also new are the headlamps featuring LED technology – with the option of an all-LED variant. The main advantages of LED technology are: 
  • long-lasting
  • colour temperature similar to daylight
  • energy efficiency, since LEDs require significantly less energy than halogen and xenon lights while offering the same level of light output 
Cabriolet roof with class-beating acoustics 
Thanks to the acoustic soft top with its particularly high-grade insulation, the E-Class Cabriolet achieves the lowest noise level in its class. The unique acoustic soft top ensures that, even at high speeds, only very little wind noise is heard in the interior. The soft top mechanism is operated fully automatically using the lever in the cabriolet control cluster or the infrared remote control. The soft top, which is suitable for automatic car washes, can be opened and closed on the move at speeds up to 40 km/h. 
Automatically safe  
A roll-over protection system integrated into the rear head restraints automatically protects the occupants in the event of the Cabriolet rolling over. It consists of two robust bars, each with a diameter of 35 mm, which are housed behind the rear backrest in cartridges inside the rear head restraints. Based on skidding movements or high acceleration resulting from an impact, a sensor can detect the risk of the vehicle rolling over, meaning that the occupants are in imminent danger. If this sensor then triggers a corresponding signal, pre-tensioned pressure springs are activated by pyrotechnic means. Both roll-over bars in the rear head restraints shoot up in a fraction of a second and lock into place automatically. In combination with the robust A-pillars, each of which is reinforced with two high-strength steel tubes, the steel bars provide highly effective roll-over protection. 
Top aerodynamics figures  
The outstanding aerodynamic qualities of the E-Class Coupé and E-Class Cabriolet have also been retained following the design modifications. Both lead the way for aerodynamic performance: the Coupé excels with a remarkably low Cd value of 0.25, while the Cabriolet achieves a class-beating figure of 0.29. 
Space for travelling  
Both Coupé and Cabriolet provide a spacious, illuminated boot. It has a capacity
of 450 litres (VDA) on the Coupé and 390 litres in the case of the Cabriolet – even with the roof down, there are still 300 litres of luggage space spare.
