The Test Track was a portion of the Moto-Hub in Le-Metru devoted to testing new land vehicles. Like the Moto-Hub in general, it was badly damaged by the earthquake that struck Metru Nui.
The Test Track was located in the southern part of Le-Metru.
Matoran were always trying to develop new types of vehicles that were faster and more efficient. All of them needed to be tested before they could be put into use, so they were brought to the Le-Metru test track. Spinouts, crashes, and explosions came with the job of testing vehicles here.
Phase dragons loved to race vehicles on the Le-Metru test track, where they used their powerful phasing ability to pass safely through solid obstacles.
