The Blue Fire trains... with lap bars !
Mack did a good job for their first looper coaster trains. We can see that they look like a lot the Maurer Floorless trains. They also have that "bleachers" configuration like Intamin's ones.
For more informations, look at that Mack Rides pdf on page 16.
Eventually, EPfans.info did a great panorama shot of the current situation:
