The 2010 BMW Z4 has officially been revealed. Click here for all the details and images.

BMW has ambitious plans for its "Z" label, with rumored plans to release more cars wearing the Z badge to join the current Z4 coupe and roadster. We’ve previously covered the possibility of a small Z2 roadster as well as a possible Z8 and Z4 replacement, but over at Winding Road is a new rendering, dubbed Z6, that could be based on 3-series running gear.

The slow selling Z4 isn't due to be replaced until 2009, but we may see a new model with minor updates before then. A suspicious looking Z4 coupe with its roof decked out in black camo gear has been caught by spy photographers. According to the source, BMW may be testing a new version with a panoramic glass roof. The tall wing and strange disc shaped antenna are likely to be testing apparatus only. Click here to see full images also at the road that winds.
