A modified Hyundai Santa Fe has become the first
passenger car to drive across Antarctica, making a trip from
Union Camp to McMurdo and back to Union Camp, as well as the first wheeled
passenger vehicle to drive across the Ross Ice Shelf.
Taking part in the journey was Patrick Bergel, the
great grandson of Ernest Shackleton, the famous Antarctic explorer who was
beaten to the South Pole by Roald Amundsen and whose quest to cross Antarctica
from coast to coast thwarted when his ship was crushed by pack ice. The journey
with the Santa Fe and three support vehicles was timed to coincide with the
100th anniversary of Shackleton’s failed attempt to cross the polar continent.
The modern day expedition was led by Gisli Jonsson
from Arctic Trucks, the company that modified the Santa Fe for its
trans-Antarctic journey. The most visible change to the Santa Fe is
the fitment of the heavy-duty low-pressure tyres. This necessitated huge wheel
arch extensions, completely new sub-frames at both ends, and a rebuilt
suspension setup. In order to account for the rugged terrain and large tyres,
the vehicle’s overall gearing was reduced by installing new gears inside the
wheel hubs.
Other changes to car include a larger 230 litre fuel
tank, and an engine pre-heater to help deal with the extreme temperatures.
Hyundai points out the engine, its management system and transmission were
completely stock standard.
The Antarctic Santa Fe was powered by a 2.2-litre
turbo-diesel motor, but instead of regular diesel, this car used jet fuel. This was done because “all operations in Antarctica run
on it”, including vehicles, and the fuel can stand temperatures as low as -58
degrees Celcius. During the journey, the car averaged around 30 km/h, although
50 to 60 km/h was the mean for many stretches. On some really smooth sections
the car managed 100 km/h for short periods of time.
The expedition had to carry its own fuel with just
two fuel cache locations along its return journey. With explorers and
scientific missions entrusted with leaving the continent in pristine condition,
the expedition had to carry all its waste back.
Thanks to modern technology, the team had it much
easier than explorers during the golden era of Antarctic exploration.
Nonetheless they still had to camp out in the bitter cold, melt snow for water,
and, probably, pee into bottles.
The convoy were able to carefully pick their way
through crevasse-filled fields, over glaciers, past an active volcano, and
travel with a degree of certainty during whiteout conditions thanks to
up-to-date satellite imagery and GPS location data. With temperatures as
touching as low as -28 degrees Celicus, the team drove for 30 days, and
sometimes for up to 20 hours per day.
