These are the first spy photos of the next-generation 3-Series sedan(F30) which is expected to go on sale end of 2011.
The car is disguised as a typical BMW prototype in black and white camouflage hiding all the little details that give the car its final touch.
Compared to the current model it gets a longer wheelbase, but the overall proportions seem to be quite similar.
BMW will put lot of effort into efficiency with their EfficientDynamics technology and of course will improve safety features. It is also expected that it will get new three cylinder turbo engines and ActiveHybrid technology for greater fuel efficiency.
