The Z2 is a smaller concept now than before , now it is using the more compact modular UKL Platform.
The Z2 will now share the platform with the next generation of MINI Coupe and Roadster. The Z2 might be rechristened Z1.
The Z2 effectively beckons the return of the Z3. With the next Z4 moving to become the Z5. Z3 is something BMW are wanting to return to because the name was hugely popular when the car was launched in 1995 , despite its ancient platform and mechanicals. Customers in droves bought the new Z3 and in certain parts of the world , Z3 waiting lists were up to two years long.
The Z3 name has always been earmarked for return.
