The standard Global Carrier (The Cobra) All Terrain Vehicle is powered by a gas turbine engine - as is its sister vehicle, the 12 wheeled Spider.
Due to its half-track configuration, however, it's considerable slower than the Spider.

A super-tuned version of the Cobra All Terrain Vehicle is used by International Rescue, for survey and field- testing expeditions in remote areas.
In the episode Desperate Intruder, Brains and Tin-Tin take IR's half-track to Lake Anasta (via a lift from Virgil and Thunderbird 2). The specially-modified half-track towed an air-conditioned caravan train with accommodations for three people, as well as laboratory and lounge areas.
