New Power, Many Refinements Mark the First Evolution of BMW’s 2-Seater Sports Car

In 2003, BMW launched an all-new 2-seater sports car, the Z4 Roadster. The Z4 Series offered two models: Z4 Roadster 2.5i and 3.0i, powered by two versions of BMW’s smooth and sonorous inline 6-cylinder engines. Firmly planted suspension, standard run-flat performance tires and state-of-the-art stability electronics were anchored in a remarkably rigid Roadster body/chassis structure; all of this was clothed in a unique and captivating look. Inside, the driver could enjoy the Z4’s innate sportiness while also savoring extensive comfort and convenience features as well as innovative design and materials.

 For 2006, the Z4 Series undergoes 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 esthetics and function.

Once again the Z4 Series consists of two Roadster models, but even their names have changed: Z4 Roadster 3.0i, replacing the former 2.5i model and base-priced at $36,295 including destination charge; and the Z4 Roadster 3.0si, replacing the former 3.0i model and priced at $42,795.
