The new Z4 gets all-new styling that is both more aggressive (front end) and cleaner (back end). A new first for the Z4 is a two-piece retractable hard-top that ditches the soft-top from the last generation.
The Z4 also employs BMW's new naming scheme (sDrive) with the sDrive30i and sDrive35i. The sDrive30i is powered by a 255 horsepower 3.0L 6-cylinder engine and the sDrive35i is powered by the 300 horsepower 3.0L twin-turbo 6-cylinder engine. Both engines can be mated to either a a 6-speed manual or a dual-clutch 7-speed automatic with paddle shifters. The sDrive30i is also available with a six-speed automatic.
The all-new Z4 will be officially unveiled next month with sales starting in the fall of 2009.
