2004 model. BMW has kept the test cars well hidden a bunch of speculation on the real look, but I would suspect something like the CS1 concept but the hardtop is a hatch:
It is expected that the entry-level engine will be an 80kW (107bhp) 1.6-litre unit. The engine range will probably also include a 1.8-litre version and the top of the range 1-series will feature a high-performance 2-litre power train with an output of 180kW (240bhp<---this sounds optimistic).
