Background: The "Twister", a new high-performance cross-country wheeled vehicle was recently put through winter-condition testing on Alaska's frozen North Slope at Prudhoe Bav. According to officials of the Lockheed Missiles and Space Company, who make the "Twister", the machine was taken north to test it in an environment which forced more conventional wheeled vehicles off the road.
The "Twister" was designed to overcome conditions which would normally stop wheeled vehicles and severely limit the effectiveness of tracked machines. The "Twister" consists of two bodies joined by a pivotal yoke. An engine in each body drives the four wheels on that section, giving the vehicle eight-wheel drive.
Engineers said that the five hundred miles (approx. 805 kms) of tests had shown that the "Twister" could operate in heavy snow and ice, often where there was no firm footing for traction. The tests also reportedly showed the "Twister" could move effectively at far higher speeds than could tracked vehicles.
Test drivers reported the driving was more difficult because the glare of the sun against the ice made it hard to spot obstacles until almost on top of them.
Military versions of the "Twister" are undergoing tests at Army bases in the United States, while Lockheed plans to continue Arctic trials to learn more about off-road operations in new environments.
