The project was co-ordinated by the car manufacturer Toyota and Top Gear, with the help of Arctic Trucks, an Icelandic vehicle modification company. The vehicle used was a modified Toyota Hilux. Toyota promoted the event under the name Hilux Arctic Challenge.
The idea was originally proposed by the BBC to coincide with the Polar Challenge race, an annual event where competitors race to the 1996 location of the magnetic north pole by trekking and cross-country skiing. The attempt would be shown as a one-off Top Gear special in 2007. As part of the challenge, the car would be racing against a dog sled, the traditional means of transport around the Arctic. Top Gear presenters James May and Jeremy Clarkson would drive the car, and Richard Hammond traveled with the dog sled, accompanied by driver Matty McNair.
