Things gotta' have a 75" track. Just a rendering though. The fact that it is only a rendering tells me that it is just an exercise for the guys in the design studio. How'd you like to roll over in that, without any A or B pillar crossover supports? Yowza! BUT, it does look pretty cool, I must admit! What I did notice besides the wide track, and lack of crossover support tubes, is how low the seats are positioned within the bodywork.
