In order to mark its 45th birthday which will take place in June 2012, AMG created a special Mercedes-Benz SL 65 AMG "45th ANNIVERSARY". The bad news is that this model will be produced in a limited edition of just 45 vehicles, but the good news is that the V12 roadster boasts an exclusive array of unusual appointments and design features.
For those who don’t know, AMG also marked its 40th Anniversary with a special edition of the CL 65 AMG. The well-known AMG brand was founded back in 1967 by Hans Werner Aufrecht and Erhard Melcher and over the past 45 years the former two-man company has evolved into a world-renowned producer of unique high-performance automobiles.
Now, let’s focus on the latest model! The new SL 65 AMG "45th ANNIVERSARY" features an Exterior Carbon-Fiber package in matt finish which is exclusive for this model. As a result, the SL 65 AMG features cross strut in the front apron, exterior mirrors and spoiler lip in carbon fiber with a satin finish. The V12 engine was also refreshed and received a high-quality engine cover consisting of matt carbon fiber and aluminum.
The rear end features twin tailpipes finished in high-gloss chrome. The design is completed by the multi-spoke forged wheels painted in titanium grey with high-sheen rim flange and matt finish.
The interior features designo Exclusive STYLE leather in titanium grey pearl/ginger beige. The AMG Performance steering wheel sports an AMG logo in its bottom bezel and offers a two-tone rim in titanium grey/ginger beige. On the ashtray cover, the model features the logo "45th ANNIVERSARY – 1 OF 45".
The new SL65 AMG from Mercedes-AMG fully utilizes the philosophy of lightweight construction for its suspension. As such, the spring links and steering knuckles of the four-link suspension in the front are composed of aluminum. Meanwhile the fully-independent multi-link suspension in the rear also has majority of its parts composed of aluminum as well. Mercedes-AMG also reduced the unsprung masses and thus improves the response of the components of the damper and spring.
It also meant that the handling agility was enhanced as well. Since the new SL65 AMG had a bodyshell made entirely of aluminum, the overall weight was lower by as much as 110 kg compared to the previous model and its steel design. This also meant that rigidity was improved, thereby enhancing comfort and safety. The lightweight construction also resulted in some of the parts being optimized to meet their particular function.
As such, different processing methods were applied when it came to the aluminum parts. These same components have been made as either vacuum die castings or permanent mould castings. They are then processed to become the extruded sections or used as materials in what would be made as sheet aluminum having different wall thicknesses.
These not only enhanced the vibration qualities but even improved the rigidity and the safety. With regards to the cover placed at the back of its tank, some parts made use of magnesium materials, which are lighter. However, to enhance safety, Mercedes-AMG also made sure to integrate high-strength steel tubes to the A-pillars.
Compared with the predecessor model's steel design, the all-aluminum bodyshell of the new SL65 AMG delivers a significant weight saving of around 110 kilograms as well as superior rigidity, safety and comfort. Intelligent lightweight construction also means that the components have been optimized in line with their specific purpose. Various types of processing are used for the aluminum components, for instance, which are produced as permanent mould castings or vacuum die castings before being processed into extruded sections or used in the form of sheet aluminum with varying wall thicknesses.
The result is high rigidity, high safety and improved vibration characteristics. For the cover behind the tank, the designers use even lighter magnesium material in certain areas. High-strength steel tubes are integrated into the A-pillars for safety reasons. Helping lower the weight is the boot lid whose inner support is now composed of lightweight carbon-fiber composite.
This is the first time such a material has been used for a production version. The composite is made up of a plastic outer shell where the carbon fiber has been bonded to it. The result is that the boot lid is lower by 5 kg compared to the standard boot lid. However this is not new as this innovation was first seen on the AMG SL models. All of these lightweight-design measures implemented resulted in the new model having EC kerb weight at 1,950 kg. Compared to the previous generation, this is lower by 170 kg.
