BMW's X6 Active Hybrid, shown in concept in Detroit last January, is close to production, as these nearly-undisguised shots of a prototype attest.

Our sources tell us that this lightly-disguised BMW X6 with the distinctive bump in the hood is a prototype of the X6 Active Hybrid. Judging by the pictures, and our source's assertion that it was seen running silently on full electric power before letting the gasoline engine kick in and accelerating off, the BMW's first hybrid will definitely be the X6, and it's on the way soon. Could we be seeing the X6 Active Hybrid on the road as a 2010 model?

The rumor mill is also talking about the possibility that the X6 Active Hybrid will be a single-color model line, adding additional distinction on the road. No word on which color that might be.
