Production of BMW 5-Series BMW Dingolfing Plant, Germany

http://www.eurocarnews.com - BMW Group - Appropriate choice of the right materials helps to balance weight on the new BMW 5 Series Sedan, enhancing both the agility of the car as well as its fuel economy and emission rating. This optimization of weight comes together with a further increase in passive safety and is possible through the appropriate use of high-strength multi-phase steel, ultra-high-strength hot-moulded steel, and aluminium. The large share of high-strength and ultra-high-strength steel gives the safety passenger cell of the new BMW 5 Series Sedan maximum stiffness and stability without the additional use of material. The positive properties of the steel used allow an increase in mean body strength and stiffness by 55 percent over the former model. The torsional stiffness of the vehicle as a function of its footprint and weight has also been significantly improved. Spring supports made of pressure-cast aluminium enhance the driving dynamics of the new BMW 5 Series in two respects, making the entire front section even stiffer and, through their low weight, further improving the overall balance of the car. For the first time the doors of the BMW 5 Series Sedan are made of aluminium, reducing weight by approximately 23 kg or 50 lb versus a conventional structure. The front side panels, the hood and a large number of the front and rear axle components are also made of this particularly light metal.
