Having already tackled the hot deserts of Uzbekistan, the Range Rover has most recently embarked on a route through the Kyrgyzstan mountains.
The treacherous route from Solihull to Mumbai, a 4,300 mile trip, is expected to be the final validation for the prototype design. If successful, the model will be suitable for full production.
All of the Range Rovers will travel through 14 countries on the route, with tough terrains waiting for the 4x4's throughout
In Kyrgyzstan, the vehicles had to negotiate the Fergana mountain range, as well as narrow and rutted mud tracks, made even more difficult by the surrounding darkness.
Despite a huge struggle that managed to test even the best in off-road vehicle design, the Range Rover was able to triumph.
Next on the route for the three machines is China, where a whole range of new challenges will present themselves.
