The event resulted in three of the Hilux models, two of which were 6x6 models, cover more than 5,900 miles each - the furthest any vehicle of its type has gone in polar history.

Toyota's invincible Hilux pickups are no stranger to Arctic weather. But this time a group of vehicles headed south to act as support vehicles for the ski races organised by Extreme World Races. The event resulted in three of the Hilux models, two of which were 6x6 models, cover more than 5,900 miles each - the furthest any vehicle of its type has gone in polar history.

The double trans-continental crossing took over four months (Nov 2011 - Feb 2012) to complete as a total of 10 Hilux models were used as support vehicles to set up fuel depots and weather stations while also providing support to scientists and ski competitors.

Tapping the special expertise of Icelandic conversion specialists Arctic Trucks, the Hilux doublecabs completed the expedition running on Jet A-1 fuel to withstand the extreme temperatures as low as -50°C and harsh terrain rising to above 3,400m.

Necessary modifications to the vehicles included fitting a crane to lift heavy equipment and a 280-liter fuel tank - 800 liters in the case of the six-wheel models. The suspension and drivetrain were strengthened, crawler gears were added to the transmission, and the extra large tires were filled to between 2.0 and 3.0psi (compared to 29.0psi for regular road-going Hilux), giving a "footprint" 17 times larger than standard tires.

Amazingly, the trucks used the standard 3.0-liter D-4D engines and transmissions with not a single technical problem.
