The ride

The roller coaster’s layout is akin to a large vertical U shape, that is loaded at the base and uses a series of LIMs to accelerate the train up each side of the track. One side of the track is twisted track that ends in a straight section angled at about 45 degrees, the other side is a perfectly vertical straight track. The train seats 28 riders in a standard overhead suspended design.

For the 2007 season, V2 was repainted red with maroon supports. Before the repainting, it had yellow track with blue supports, which made this ride's paint scheme very similar to Wicked Twister at Cedar Point, which has yellow track and green supports.

On April 3rd, 2019, the park sent a newsletter announcing renovations to rebrand the coaster into The Flash: Vertical Velocity, which would open next to the park's new 4-D coaster,. The opening of the two coasters rebranded that area of the park to a DC Comics-themed land, standing along with, The Joker and the previous year's project, Harley Quinn Crazy Coaster. Vertical Velocity's supports were painted yellow for the new theme.
