Z4 Roadster

Introduced in 2003, the Z4 Roadster has been the longstanding BMW representative in the two-seater sports car category. The predecessor to the wildly popular Z3 Roadster, the Z4 is powerful and sporting in both design and performance.

In 2006, the Z4 Roadster series, consisting of the 3.0i and 3.0si models, underwent its first major evolution. Heading its extensive list of updates and improvements are all-new, more powerful engines; 6-speed manual and automatic transmissions across the board; more powerful brakes, standard 17-in. wheels and tires now on both models, and a more advanced Dynamic Stability Control system. Along with all this driving-oriented progress, design and materials refinements inside and out enhance both aesthetics and function.

Z4 Roadster features include:

3.0-liter DOHC 24-valve inline 6-cylinder engine with Valvetronic variable intake-valve lift and Double-VANOS steplessly variable valve timing: 215 (3.0i) or 255 hp (3.0si)
Choice of 6-speed manual transmission or 6-speed STEPTRONIC automatic transmission
High-rigidity roadster body/chassis unit with aluminum hood
Wide track, extremely low center of gravity with electric power steering
Dynamic Stability Control (traction and stability system)
Front-impact Supplementary Restraint System with 2-stage "smart" airbags and side-impact airbags
