The three terms Coupé, sport and lightweight construction, united in the contraction CSL, have a long tradition. Already 1938 developed legendary 328 mille the Miglia Coupé with aluminum outer skin, and in the 70's on the basis of the 3,0-l-Coupés at that time a lightweight construction haven car was built. On the international motor show 2001 BMW M with the M3 CSL Concept Car took up this topic again and the hearts of all sports car fans more highly strike to let. After the overwhelming resonance now on series conditions of representable M3 CSL prototype follows as preliminary stage for a later series vehicle. The "intelligent lightweight construction" forms the basis of the new M3 CSL. The optimal combination of material and construction unit is named, which uses the best suitable material depending upon the specific requirements of a component. Formel-1-Technologie with lightweight construction and drive. This strategy leads directly to the Formel-1-Technologie, which the M3 CSL transfers in fundamental ranges for the employment on the road. So consistently carbon fiber reinforced plastic (CFK) was used, the Formel-1-Werkstoff absolutely. Thus BMW M introduces the reversal of the weight spiral in a fascinating form. In the drive range for it the high speed concept of the well-known M3-Reihensechszylinders, which integrates the lightweight construction on the engine sector, stands. With the modified engine the complete gas exchange and the friction achievement were revised. For the very fast course change with according to direct traction power connection the Sequenzielle serves M transmission with Drivelogic (SMG), which is likewise directly be based a concept component for the sportiest M3, integral on Formel-1-Technologie and. Altogether the lightweight construction haven car is thus appropriate for a puristic dynamic experience in its total composition and tuning. Lightweight construction is certainly no self purpose been with the development of the M3 CSL by BMW M. Because the absolute weight and the mass inertia of an automobile around the vertical axis are decisive for the crosswise -, high and longitudinal dynamics - thus for it as the driver experiences the driving dynamics. Besides the weight per horsepower, the quotient from vehicle weight and vehicle achievement, is the crucial factor for as high a longitudinal dynamics as possible, for as high an acceleration as possible. Completely after the 110-Prozent-Formel of M business field leader Gerhard judge: "if we in the M3 CSL a weight per horsepower smaller around again ten per cent to obtain can, we the 110-Prozent-Auto and thus the jump into a new dynamic class created." In order to test all these dynamic criteria fast and thoroughly, there are no better place than the Nuerburgring Nordschleife, the most fastidious racing course of the world. There the chaff separates from wheat in drivingdynamic regard, since the interaction of all vehicle components becomes experiencable. Further weight reduction by purposeful employment of alternative materials. In wide ranges the lightweight construction concept is formally in the face written the M3 CSL: The Flaps in the front apron, roof and tail diffuser is visible from CFK. Of painted carbon fiber beyond that the front apron consists. Door and cowls as well as the center console are likewise manufactured from this material. But it does not have to be always carbon fiber: The carrier structure of the asymmetrically divisible Durchlade consists of continuous glass fiber thermoplastic, an innovative material of air and space travel. The front seats in shell construction from GRP (glass fiber strengthened plastic) are not only more easily than the series seats of the M3, them offer the passenger also still more stop with sporty driving fashion. The back window of the M3 CSL is from duennglas, when baggage compartment floor serves a honeycomb sandwich slab, likewise a material, which is preferably used in air and space travel. Even the basis of the carpet consists of an weight-optimized foam document. The M3 CSL stands for new sport tyre, a 18-Zoll-Bremsanlage on particularly developed 19-Zoll-Raedern with one - completely the puristic concept following - provides for fulminante delay values. Following thereby an automobile for engine-sporty enthusiasts with BMW M, who appreciate the drivingdynamic purism as ultimative driving feeling, develops for the tradition completely. Already in the next year this M3 CSL in a limited number of items is offered.
