Mercedes-Benz-Blog TRIVIA: From "Sport Light" To SL Legend - PART IV
The concept of open two-seater and easily operated, weatherproof top was so successful that even the 300 SL was modified correspondingly. In the spring of 1957, the legendary Gullwing was replaced by a roadster version that from then on permitted open-top motoring even in this class of high-performance sports cars. With this roadster, Mercedes-Benz offered its customers a car for comfortable and fast traveling - or a luxurious cabriolet. Purists and coupe owners, however, referred to the new model as "living room on wheels". An extra weight of 100 kilograms did not exactly benefit performance but at an unchanged output of 215 hp, the roaster still had plenty of muscle. The tubular grid-type frame was retained as the backbone for the roadster as well, though significantly modified in the areas of the doors and rear end. In this way, the engineers created space for an - albeit small - trunk and for "proper" doors which made getting in and out clearly more convenient. A new rear axle - a single-joint swing axle with balancing spring - was incorporated, improving both handling and ride. In 1961, the turbo-cooled duplex drum brakes were replaced by modern disc brakes.
Its soft-top - operated easily and conveniently - vanished underneath a separate cover behind the seats. The car's external appearance continued to be unmistakably SL, its face being characterized by headlamp and turn signal integrated under a common lens on each side. A swage line extending from the upper edge in the air outlet in the fender far into the door caught the eye when looking at the car from the side. The company complemented the package by an elegant, easy-to-fit hardtop for winter sports fans in the fall of 1958. This hardtop was so much in demand that it soon became the most frequently ordered option. There was a special, high-performance sports version of the roadster that deserves to be mentioned. At the wheel of this car, O鈥橲hea won the Class D of the 1957 US Sports Car Championship in superior fashion, with three times as many points as the runner-up, Caroll Shelby on Maserati. This last significant championship marked the end of the glorious career of the 300 SL in motor sport - five years after the first 300 SL's start. The 1,858th - and last - 300 SL roadster came off the assembly line on February 8, 1963, taking the ingenious design of the tubular grid-type frame and the robust, reliable and powerful direct-injection gasoline engine with it.
Like all other standard Mercedes-Benz production engines, the diesel engine onboard the Vision C 220 BLUETEC has a four-cylinder powertrain system. The drivetrain includes four valves per cylinder, third-generation direct common-rail injection system, turbocharger with a variable nozzle turbine and exhaust gas recirculation. How does the BLUETEC clean diesel technology work? First, the system uses an oxidizing Mercedes-Benz catalytic converter that functions to reduce carbon monoxide (CO) and unburnd hydrocarbon (HC) contents from the exhaust. Next, another catalytic converter called the DeNOx removes oxides with the help of a particulate filter. Lastly, a selective catalytic reduction (SCR) catalytic converter converts the other nitrogen oxides into pure nitrogen and water, with the injection of AdBlue, a urea-based material that helps to the conversion process. Meanwhile, according to Mercedes-Benz, they are planning to offer three model classes equipped with BLUETEC diesel engines to roll out in the U.S. These include the R-Class crossover SUV, M-Class 4-door SUV, and the GL-Class full size luxury crossover SUV.
Some car savvy people referred Aston Martin Lagonda as a revival of 1970s Aston Martin. It has been revealed that Mercedes Benz and Aston Martin are looking for some sort of partnership in order to reduce the cost and time on the upcoming models. The people can expect some famous gadgets in the car. There are different kinds of gadgets available in car which is completely new for the audience. There are very few details available on this model but definitely all the responsibility is on the Mercedes when it comes to engineering. The design of Aston Martin is taken from two cars to introduce a power packed one car. The S-Class of 2009 has acquired good looks but it is to be believed that Aston will have better looks. Also, President of Lagonda clarifies that the design of this car is not at all like Aston. A spokesperson also lay out plan and as neglected to mention acronym of this SUV.
