The SLS AMG Roadster convertible is the second car to be developed independently by AMG. Coupe and Roadster concepts were created in parallel - very advantageous in the development process. During this development period of 3 years for the SLS AMG Roadster 2012, the engineers paid special attention to body rigidity, driving dynamics, the top and NVH.
Is currently testing in Stuttgart in 2012 SLS AMG Roadster are minimally disguised covering the test routes. Fans readily identified, these two places, soft fabric is the Mercedes star, or model designations to be seen, just black adhesive sheet front, behind and around the edges. The proportions speaks for itself, with a long hood, short rear wheels large and unified design breathtaking.

There are still six months before the world premiere at the IAA Motor Show in Frankfurt in September l, 2011. Enough time to check the maturity of the new SLS AMG Roadster. AMG staff have already completed most of the work done since the Coupe and Roadster were created in parallel. Development and testing of a new high-performance AMG car is based on the digital prototype (DPT). Investigations to help achieve specific goals, such as body design, weight distribution, engine position, the center of gravity of the shaft design. Recent simulation programs allow engineers to test driving dynamics, aerodynamics, ergonomics, crash behavior and production process. The digital prototype is a complete solution, the virtual car.
In the process of AMG also uses the experience of his colleagues at Mercedes-Benz, in collaboration with the departments for the development of Mercedes-Benz at the Mercedes Technology Center (MTC) in Sindelfingen.

The latest simulation software and detailed evidence on every continent to have 563 hp Roadster for launch in the U.S. market in late 2011. Affalterbach Specialists focuses specifically on the rigidity of the body, driving dynamics, the top and NVH - ". Noise, vibration and shock"
Summary: stiffness, performance and fit a soft top.
Of course, all these aspects of development are closely linked, as Tobias Moers (44), Director of Development and member of the Board, Mercedes-AMG, says: ". Without the rigidity of the body has nothing to do with the dynamics and can not be guaranteed a comfortable soft close "Like the roadster option was already taken into account in the conceptual phase of the SLS AMG, lightweight and highly rigid aluminum frame is then defined at an early stage. Due to the lack of a fixed roof and gullwing doors, it was necessary to design sivuhelmaverhoukset decisive, not only crash performance, but because the evidence showed that the dynamics could be improved further strengthening this area. Tobias Moers: "SLS AMG Roadster is a super-sports - just like the coupe goes without saying that AMG is also determined to achieve a superior driving dynamics of this variant convertible .."

To achieve dynamic manipulation identical to the Coupé - without a fixed roof - the Roadster has two features designed to increase the rigidity of the body: body-covering against the dashboard has other pillars of the windscreen and the structure tunnel, and a structure between the bonnet and the deposit will harden the rear axle. These features prevent unwanted vibrations from the beginning and have the extra weight, plus the vibration dampers are often used by competitors. Because of this rigidity, the hood can open and close reliably at speeds electro while moving 31 mph. The body of the Roadster tips the scales at only 536 pounds - which is comparable to the weakest, 531 pounds of SLS AMG Coupé body.
Some specific changes to the spatial structure of aluminum.
Without a fixed roof and gull-wing doors, the SLS AMG Cabriolet has a strengthening across behind the seats which supports the bearing system of fixed protection. The 250-watt subwoofer system Bang & Olufsen BeoSound high-end AMG is in the Cross Cup instead of the tablet. A particular challenge is the insulation of cross members, which acts as a subwoofer enclosure for two 6.5-inch speakers connected in series. Many improvements were necessary before the desired listening pleasure is achieved. Only with the help of a special wall in the aluminum through the system was considered ready.

The three-layer fabric SLS AMG Roadster soft top, which is stored behind the seats in a Z-formation to save space, is also relevant for the dynamics of manipulation. The optimum weight of magnesium / steel / aluminum construction provides a low center of gravity and is designed for speeds up to 197 mph (electronically limited). Engineers said they are open or closed, even at full speed, there should be no interference to overcome, booming whistling, hissing click, or screaming. Similarly, the WindStop Plexiglas and wood paneling on the inside of the hood and along the waist must be free of vibration. These tests were carried out accurately defined high-speed track in Papenburg, Nardo (Italy) and Idiada (Spain).
The audio quality, the AMG engineers checked with advanced measurement techniques, also covered by another characteristic - the transparent, stuck in the rear window made of safety glass single layer. A special manufacturing process not only provides a smooth transition between the outer skin of the hood and glass, but also leads to low wind noise when the roof is closed - at all speeds.

125 years of experience with innovations in convertible vehicles.
Make sure that the wind is soft and resistant to water is a complex business, AMG and Mercedes-Benz has spent an enormous experience gained during the 125 years of experience. Convertibles have always been rich in history Mercedes-Benz.
The developers of the SLS AMG Roadster 2012 a great attention to water, sand, dust, heat and cold. A special feature of compact soft top is the continuous water exchange: that is attached under the hood to capture rainwater and direct it to the slab with two openings on each side.
Endurance test with 16 criteria: the "Sindelfingen rain test."
Rain test Mercedes (MTC) in Sindelfingen is particularly demanding, and each new vehicle is equipped with a Mercedes star is transferred to it - whether it's a fixed roof, soft or retractable hardtop. Extreme amounts of water are used to ensure that development is the result of water-resistant - which is a special challenge in the case of convertible or roadster. 16 tests must pass before the concession.
The studies include the hose test - when all soft top, doors and shutters are sprayed with a water hose, test the continuous rain during the night, a driving test, glaze, swirl and high pressure test and a final meeting in a automatic car wash. The test simulates the rain all the possible situations that may occur on all continents.
Bench tests and practical tests in all climate zones.
In addition to testing facilities such as water reservoir and tunnel climate / wind power, AMG specialists conduct test drives in all climatic regions of the world. In Laredo, Texas, for example, there is a particularly fine dust that finds its way into almost every hole to test the absolute limits of the seals.
The top compact, soft fabric that can be conveniently opened and closed in just 11 seconds with the push of a button to a speed of 31 mph, must also undergo various tortures. One of them is the best standardized test used gentle resistance for all new Mercedes convertibles and convertibles: 20,000 closing cycles on a test set, followed by 2500 cycles closing movement (whether in extreme heat, cold, humidity or dry winds of the desert).
The final quality test of endurance.
While all tests have been adopted for development and production tests on the Mercedes-Benz plant in Sindelfingen have been successful, the developers have not yet reached its goal. Attention now turns to the quality of the entire vehicle for resistance testing. These simulate a vehicle's life in extreme cycles of accelerated aging test.
Endurance at a glance:.
• Long-term testing of a variety of ways:
All components and systems are tested together in everyday function. Loaded to their gross weight, the test cars are subjected to a well-defined test program on country roads, motorways and in city traffic.
• Endurance tests on paved surfaces:
In this case, the developers focused on the sustainability of parts of the chassis and suspension, the whole body, and a solid front subframe, the steering and the engine is installed. The test cars are loaded to their gross weight.
• "Fast track" endurance testing:
Test the whole vehicle, focusing on powertrain, chassis and suspension. AMG features of the program covers 6200 miles in two loops of the Nürburgring North and urban traffic.
• to test the resistance load:
Extreme maneuvers acceleration and braking with a full load frequency, which impose extreme demands on the cooling, fuel and braking systems.
• long-term corrosion tests:
Corrosion tests of the entire vehicle simulates the harshest climatic and dynamic environmental influences.
• Approval of the Board:
All-inclusive testing of the finished product.
