s to accelerate the train up each side of the track. One side of the track is twisted track (commonly called an inline twist) that ends in a straight section angled at about 45 degrees, the other side is a perfectly vertical straight track. Seating on the one train holding twenty eight riders is a standard overhead suspended design.

When it was installed the ride was 186 ft (56.7 m). Both sides of the track were vertical, the front spike twisted, and the rear spike straight with a brake segment at the top (designed to hold the train momentarily). In 2002, the ride was temporarily closed while the track was modified from 186 feet (56.7 m) to the city ordinance limit of 150 feet (45.7 m). To lower the height, the front tower was tilted to a 45-degree angle and the reverse tower lowered to 150 feet (45.7 m).

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 Vertical Velocity
