This is the South Korean XK2 Black Panther. Rendered using global illumination with Mental Ray. It should be done in Maya 7.0 if I remember correctly.
It was actually done in March 2007 but was never used. I've made it available for download under a creative commons license. It's a Maya project folder zipped up.
If you use this in your work, I would love to see it.
