Week 1- History and mission Statement..

From old school to new school. As may see how the years change the style and model of what use has become the BMW 5 series sedan.   
The BMW E12 BMW 5-Series was made between 1972 and 1981. The E12 was the first series to bear the 5 Series name: the '5' denoting BMW's fifth 'New Class' platform. Designed as a replacement for the popular BMW new class mid-size sedan, the E12 5-Series models were smaller than the large BMW E3 sedan but larger than the two-door 2002 models. The E12 was replaced by the BMW E28 5 Series in 1981. This BMW was designed to compete with the Mercedes-Benz W114 sedans.The 5 Series began the BMW tradition of being named with a three-digit number. The first digit (5 in this case) represents the model, and the following two digits (usually) represent the size of the engine in deciliters, which is the main distinguishing difference. Additional letters or words may be added to the end of the three-digit number to define the fuel type (petrol or diesel), engine or transmission details, and the body style. The 'i' originally stood for (fuel) 'injection'. 

BMW's mission statement for now and up to 2020 is clearly defined: that the BMW Group is the world's leading provider of premium products and premium services for individual mobility."
