BMW has announced their newly redesigned 2009 Z4 roadster will start at $46,575 for the entry-level sDrive30i and $52,475 for the high-performance sDrive35i.

Both versions receive a new folding-metal retractable roof and noticeable gains in performance but these enhancements come at steep price as the 2009 Z4 sDrive30i boasts a massive $9,875 price increase compared to the 2008 Z4 3.0i while the 2009 sDrive35i features a $8,400 increase compared to the 2008 Z4 3.0si. While the new pricing strategy might turn off some buyers, it creates room for the 1-series convertible as well as brings the new Z4 in line with rivals such as the $46,825 Mercedes SLK300 and the $46,600 Porsche Boxster.

As with all BMWs a long list of options is available, the $1,000 cold weather package features a heated steering wheel and heated seats while the premium package boasts auto-dimming mirrors, power seats, ambient lighting, and BMW assist. For $2,300 potential owners can equip their new Z4 with a sports package that comes with 18" light alloy wheels, an adaptive M sports suspension, sports seats, and a higher top speed. Another notable option is the $1,525 seven-speed double clutch transmission which is only available on the Z4 sDrive35i.

Power for the sDrive30i comes from a naturally aspirated 3.0-liter inline six-cylinder engine which produces 255 hp and 200 lb-ft of torque while the sDrive35i uses a turbocharged 3.0-liter engine that cranks out 300 hp and 300 lb-ft of torque.
