I noticed that too. I'm pretty sure that it's just an error in the computer rendering. Otherwise, the front car would tilt forward and scrape along the track, which would definitely add to the thrill factor in a dying/severe injury sort of way. Either that, or there's a really strong beam underneath the car holding up the front of it.
I think the PTC cars may look better, but these cars look like they'll be very comfortable. It'll also be interesting to see a 14 car train. I wish I could get out to Holiday World and ride this thing!
My bet is that its done like B&M Floorless trains. The first and second car can only roll in relation to each other, and all the other cars in the train can pitch, yaw, and and roll in relation to each other. So the first car effectively becomes the zero car. This is the same thing that is done with a zero car on Flyers and most B&M trains, but they just plopped a pair of seats on the zero car in this case.
I didn't even think about how B&M floorless coasters have no zero car. That would make sense. However, I still think there may be a set of wheels missing from the rendering. That front car just looks really weird with so much of it sticking out in front of the wheels.
