Concepts and Prototypes: Ice Scout

A legendary sports-car builder engineers a featherweight, ethanol-powered supercar on skis to lead an expedition across Antarctica

When you're driving a 4.7-ton truck filled with scientific equipment across a crevasse-strewn Antarctic wasteland, choosing the right path is critical. Deep cracks in the ice, invisible from a distance, can swallow a truck whole. An Antarctic expedition needs an ultra-light scout vehicle to run ahead and find a safe route before the heavy machinery rolls through. That's exactly what the Concept Ice Vehicle (CIV) is built to do.

Shifting through the mossy undergrowth of Germanys Black Forest, antennae raised and leg joints quietly clicking forward, OLE (pronounced oh-luh) is a St. Bernardsize bug on the prowl. But this mechanized insect isnt a scavenger—its a guardian.
