Impulse is a roller coaster in Thrill Rides at Knoebels. While it's not the best, it is also recommended. The minimum height to ride is 48 inches.
A new-for-2015 Zierer Tower Coaster featuring a 98' verticle lift hill, 90-degree vertical first drop, cobra roll, vertical loop, heartline roll, and two helixes. It is the single largest project (by budget) in Knoebels history. With the addition of Impulse, it will be the first time since 2004 that the park has had a roller coaster with inversions.
