Probably the most interesting design change of the 2009 BMW Z4 E89 at the exterior is the hardtop.
This new element has a great effect visually and it is also functional. The car has a very long hood and a long wheelbase. The total length of the 2009 BMW Z4 E89 is 4.2 meters, which is roughly 165″. At the moment, only two sets of pictures were released by BMW, one with a classic look and this blue version. Personally, I like the blue 2009 BMW Z4 E89 better. Many people say that the design of this car is the best design ever created by BMW and there is a huge difference between the old Z3 and this new Z4.
In the end, with the 2009 BMW Z4 E89 BMW has managed to combine functionally with amazing looks and they did this without a flaw.
