A class leader since its inception, the 5-series remains a crucial car in BMW's lineup, so there's a great deal of anticipation surrounding the next-generation model. That car is due to arrive late this year for the 2010 model year, and heavily disguised sedan prototypes have already been seen testing around the streets of Munich, as have Touring variants. Today new details have emerged from Germany outlining the car's appearance and features. Most of the planned changes are just skin-deep. Contrary to some reports that the 5-series would shrug off its controversial exterior for the next generation, the latest news, issuing from Auto Zeitung, reveals that BMW may in fact be embracing the 5-series' polarizing looks, including some influence from the inflammatory CS Concept.
