While the recently revealed 2004 5 Series makes use of the "flame surfacing" idea favored by BMW's current head of design, the next 3 Series looks more like a smaller version of the previous 5 Series. Engine choices probably won't change all that much although the high-performance Motorsport coupe (likely renamed 4 Series) is expected to get V8 power. BMW's iDrive control system is a probable addition along with plenty of other new comfort and convenience features necessary to keep the best-selling sedan at the top of the sales charts.
