Here are the very first spy photos of the BMW Z4 successor: the BMW Z5 Roadster. This heavily camouflaged prototype reveals dimentios that are larger than the current BMW Z4 while featuring a soft top compared to the hard cover found on the Z4.
At the 2015 Geneva Motor Show, Klaus Frohlich, BMW head of R&D told the press that not only a Z4 replacement is in works, and that it will be made in cooperation with Toyota.
With first test cars appearing public roads now, the Z5 is likely to be unveiled by 2018.
