Saw the Atacama Yellow Z4 2.8 at the New York Auto Show this morning during a BMWCCA preview. They had the hood release taped over so you couldn't pop the bonnet. The marketing guy said it was a prototype and they couldn't show it. My guess is that it was a rebadged 3.0i and that the turbo 4 was not under the hood.
Why "launch" the car if the major feature of the model is not viewable
?
