Land Rover has kicked off Expedition 001, a journey to the world premiere of the new Defender SUV. The road to reveal begins in the Valley of the Castles in Charyn Canyon, Kazakhstan. From here, the SUV will travel all the way to Germany for the Frankfurt Motor Show (IAA), where it will be officially revealed on September 10.

Expedition 001 marks the last leg of an exhaustive global testing program which saw new Defender undergo 45,000 individual tests and endure temperatures ranging from -40 to +50 Celsius, over 1.2 million kilometers of driving. The maximum altitude the Defender was tested at is 10,000 feet above sea-level.

Defender prototype wearing camouflage was also the first vehicle to complete the legendary Goodwood hillclimb.

Prototype models have already been tested by members of charity Tusk on location in Borana, Kenya, to support lion conservation and been driven through the dunes of Dubai by the fleet experts from the International Federation of Red Cross (IFRC) and Red Crescent Societies.

During the Dubai test, Land Rover engineers demonstrated the vehicle’s 4×4 capability to their IFRC counterparts both on and off road, before the IFRC fleet experts drove the vehicle for themselves on the region’s sand dunes and the twisty tarmac of Jebel Jais highway. They also took it all the way up to the tallest mountain in the UAE.

The maximum altitude the Defender was tested at is 10,000 feet above sea-level.

Earlier this year, the Defender was also shown at the Goodwood Festival of Speed. Driven into the event by the Duke of Richmond, the Defender prototype wearing camouflage was also the first vehicle to complete the legendary Goodwood Hillclimb.

Over the years, the Defender had earned a reputation for being a reliable vehicle for use in adverse conditions both by adventure and travel enthusiasts as well as by various government and charitable organizations working in hostile environments.So the new Defender has big shoes to fill and how it matches up to its legacy will be known when details are revealed at Frankfurt.
