Z2 Roadster is Nixed
While a BMW supercar may yet come, the rumored Z2 roadster is reportedly stillborn, at least in RWD form. CEO Reithofer reportedly nixed the return of a compact RWD roadster because the numbers did not work out. If a compact roadster returns at some point in the future, it will be built on a FWD platform which it will share with the MINI convertible.
