Pantherian (originally known as Intimidator 305 and temporarily named Project 305 for the 2024 season) is a steel roller coaster located at Kings Dominion in Doswell, Virginia, United States.

[1] Standing at 305 feet (93 m) tall and reaching speeds up to 90 mph (145 km/h), it is the second giga coaster to be built in North America, following Millennium Force at Cedar Point.

[5] At its highest point, Pantherian reaches a height greater than the observation platform of the park's tallest structure, the Eiffel Tower attraction.

[6] Following Intimidator 305's first operating season, the first turn on the ride underwent a major reconstruction to reduce the number of greyouts and blackouts reportedly being experienced by some riders.

[18][15] The plaza near the ride's entrance featured Dale Earnhardt's black Monte Carlo on display, as well as commemorative plaques celebrating the famed driver's career.

[16] Project 305 was one of two roller coasters themed to Earnhardt that opened in 2010; the other was Intimidator, a hypercoaster manufactured by Bolliger & Mabillard at Carowinds, another Cedar Fair park.

[19] Kings Dominion officials hoped that the ride would attract guests,[15] and the park recorded increased attendance during the 2010 season as a result.

[9][19] Some riders experienced problems on that turn because of extremely high positive G-forces produced by the ride's original design.

[21][22] To lower the number of occurrences, Kings Dominion reduced the coaster's maximum speed by temporarily installing trim brakes on the first drop.

[22] The major modification allowed them to remove the trim brakes on the first drop, returning the ride to its original maximum speed of 90 mph (145 km/h).

The trains are arranged in stadium-style seating with overhead lap bars fitted with soft, padded over-the-shoulder straps.

"[31] A reporter for the Richmond Times-Dispatch wrote: "Mercifully, the ascent is swift and without pause at the peak, so there's no time to process what's happening.

[32] On July 9, 2013, before the park opened for the day, one of the trains was performing a test run when it became stuck near the top of the lift hill.

Kings Dominion later explained the closure through a statement released on their official Facebook page on August 28, 2013, which stated that a problem with the weight distribution on the gearbox caused a part to warp and fail.
