When we see photos of camouflaged pre-production vehicles undergoing road tests, these are often provided to us by our eagle-eyed spies. Rarely do manufacturers themselves release testing photos of their upcoming vehicles; more so, documenting and showing them on social media. However, Rolls-Royce seems to think otherwise with the upcoming Cullinan. The British luxury marque announced that they have teamed up with National Geographic to document the luxury SUV's final testing in a series called 'The Final Challenge'.

Rolls-Royce has already sent Cullinan prototypes to Europe, the Middle East, and the United States for final testing before it makes its world premiere later this year. Joining them will be videographers and photographers from National Geographic, who will be filming the final updates of the SUV's test program. Leading the NatGeo team will be Cory Richards, who was awarded National Geographic’s 2012 Adventurer of the Year.

“I promised the public three years ago that I would involve them in the development and testing of the Rolls-Royce Cullinan, and I continue to keep that promise by making The Final Challenge, a public trial. Today’s public and customers will see Rolls-Royce in a wholly new light as Cullinan demonstrates just how capable a Rolls-Royce can be,” said Torsten Müller-Ötvös, Rolls-Royce CEO.

While we do get to see the new Rolls-Royce Cullinan undergoing tests, the luxury marque has yet to reveal any details about the upcoming SUV. From both spy and official photos, it is expected to have a design similar to that of the current-generation Phantom. It is also rumored to be riding on a variant of the Phantom chassis and using the same twin-turbo V12 engine.

At the moment, there is still no official date on the Rolls-Royce Cullinan's debut. For now, we can watch it tackle the toughest terrains around  thanks to National Geographic. Those interested in following 'The Final Challenge' may visit the National Geographic website or on Rolls-Royce social media accounts.
