Yes it´s a Z8
- what a pity, there were only built a little of
pieces (I don´t know the exact number at the moment!). At first time you´ve
got seen it in the one James Bond trailer with the oil-pipeline in Russia. The bad guy in the helicopter cut it in two halves with his big saw!
The Z8 became an own platform, the Z3 based on the E36 and Z4 should become a lot of the E46, but for the last I´m not quite shure.
