Teststrecke, meaning Test Track in German, is a portable steel roller coaster owned by the German showman partnership Meyer & Rosenzweig. It was imported from Dorney Park & Wildwater Kingdom in 2008 and generally tours in Germany, with occasional visits to the Netherlands. It was designed by renowned ride engineer Anton Schwarzkopf. The ride was previously named Laser and Colossus.

The trains on Teststrecke are themed to resemble racing cars and designed by Sunkid GmbH. Each train has a single lap bars to secure riders in their seats. It can operate all three at peak times, but it runs with one when there are no queues. The coaster is portable in that it is not attached to the ground, but is anchored by pools of water.

The ride[edit]

The ride starts with a slow 93-foot chain lift hill, leading to a right hand near vertical curved first drop, and two consecutive vertical loops. The ride then turns into left-hand helix, up and through the center of second loop. Another left turn helix, goes down and goes straight upward diagonally between the vertical loops, followed by a 360-degree helix, starting from right, leading into a brake run that leads into two right turns and back into the station.
