Meet the one-off Bertone Mantide — part Corvette ZR1, part Italian model, all sex appeal. Designed by Jason Castriota, the Mantide may even outshine his last great design, James Glickenhaus' Pininfarina P4/5. Exclusive gallery below.

We recently learned the Corvette ZR1-based Project M will be called the Mantide. Thanks to this wind tunnel photo we've lightened up a bit, we also have an idea of what it will look like.

One episode of Bradley Farrell's "Inside Project M" documentary on Bertone's new concept left before the car's officially unveiled. For now, there's this new teaser shot that's got us asking, is it Nissan GT-R-based?

We exclusively revealed Jason Castriota's plans for a new Bertone one-off project supercar, and we've already shown you the first episode of Bradley Farrell's documentary. Here's chapter two. And oh, hey, look, it's smiling!

After the documentary teaser last week, here's the first chapter featuring Jason Castriota gearing up for the launch of his new supercar in April at his new workplace, Stile Bertone. Also, the teaser shot above.

Jason Castriota, the designer of James Glickenhaus' breathtakingly beautiful P4/5, is now working with Stile Bertone. He's developing a one-off super car to be revealed at April's Shanghai Auto Show. We've got the inside story.
