Using specially-modified buses with massive tires, the group slowly drove 2,485 miles in 70 days over drifting ice, occasionally using a pickaxe to clear a path and staying on guard for chasms that could open up and plunge the team into the frigid arctic waters. Average speeds were about 6 mph, "at the speed of a (farm) tractor." While the big tires technically allowed the buses to float if the need arose, the team preferred to stay out of the water to keep the suspension from getting coated in thick, hard ice. Falling in on foot would mean almost certain death.
According to Phys.org, the buses were powered by Toyota diesel engines, but were built with prototype parts from a previous driving expedition to the North Pole. Right now, the machines are parked in a garage in Canada's Resolute Bay while the the team rests up with family back home. They plan to continue their trek to back across the Bering Straight to Russia. If successful, the team may eventually offer a version of their buses for commercial sale.
