BMW unveils 2010 Z4 Roadster ahead of Detroit Auto Show Debut

BMW has released the first details and images for its all-new BMW Z4 Roadster, which is set to make its debut next month at the 2009 Detroit Auto Show before going on sale in the following months. The design of the new Z4 comes out through classic details interpreted in a very modern style, highlighted by an automated folding aluminum roof. The hardtop brings the Z4 in line with the competition, opening and closing in 20 seconds. The weight penalty is offset by greater security, better visibility and greater comfort. The side windows are 40% larger than the outgoing soft-top model, and the rear window is fully 52% larger. The Z4 also keeps its classic roadster proportions, with a long hood, short overhangs, and strong shoulders. However, the car's styling has been modernized with new integrated LED indicators on its flanks as well as on the head and tail-lamps.
