Way back when Apollo’s Chariot made it’s debut,
it featured the original 4 across B&M mega coaster train design, and for the longest
time, that’s the way things were. It wasn’t until 2008, when Canada’s Wonderland opened Behemoth, was there an alternative design. The new design featured staggered “stadium seating.” Giving each seat a more open air feel, and in turn, due to the longer more spread out cars, each train is longer, resulting in varied experiences depending on whether you sit at the front or back.
Something else that changed with the seating layout, is the zero car. As you can probably tell from the pictures, the original design, used on Leviathan, has a sunk in triangle pointed out, and in the new staggered layout, it has more rounded design, with a raised, rounded point in the middle. This change may be purely aesthetic, as the zero car design has varied on staggered trains on all B&M megas with them, as Diamondback, and Intimidator have unique designs.
