Much to our dismay, the mysterious one-off supercar that Stile Bertone is going to introduce at this month’s Shanghai Auto Show in China will not be based on the Nissan GT-R. The sixth episode of Bertone’s ‘Project M’ documentary-style video series reveals that the supercar that the Italian firm’s Design Director, John Castriota, is working on uses the underpinnings of the Corvette ZR1. Cool but in our opinion, far less intriguing than if it were based on the GT-R. Click through to watch the new episode on the ‘Project M’.
