In conjunction with the M Sport Package, the 2015 BMW Z4 Roadster will be available for the first time in Estoril Blue metallic as from July 2015. Just like the other BMW models with the M Sport Package, the Z4 can now make use of the beautiful blue shade which denotes sportiness and speed.

While BMW struggles with the Z4 sales, the only roadster in the line-up is still one of the best looking bimmers one can buy today. With the premium roadster market spiraling down, it remains to be seen whether BMW will launch a refreshed Z4 or simply reviving the BMW roadster with a brand new model.

At the 2015 Geneva Motor Show, Klaus Frohlich, BMW’s new head of R&D, told the press that not only a Z4 replacement is in works, but also confirmed that it will be developed together with Toyota.

BMW and Toyota currently collaborate on a common sports car architecture, hybrid drivetrains and lightweight technologies. The collaboration will allow both companies to save significant R&D costs.

The global market for roadsters has declined forcing BMW to seek a cost-effective way to update the two-seater.

Z4 sales declined by 11 percent to about 5,300 cars in Europe last year, according to data from JATO Dynamics. BMW said it U.S. volumes for the Z4 fell 13 percent to 2,150 cars. Typically the three biggest markets for the segment are the U.S., UK and Germany.
