This following video was shot in Death Valley where journalists from MotorTrend have initiated a 7-passenger luxury SUV battle involving the Land Rover LR4 vs the Lexus GX460 vs the Mercedes GL450.
Surprisingly this review video places the 2010 Mercedes GL450 third as two of its main disadvantages are the lack a lower range transfer case as well as the fact that its base sticker price is 61,825 USD.   
What is not surprising is the Land Rover LR4 emerging as the winner in this comparison test. The British SUV can conquer any type of terrain, in any kind of weather, with a roomy interior and a decent price tag.
As for the Lexus GX460, MotorTrend thinks that the stability control system is not that bad, and that the car never felt unsafe.  
Watch the video with the Land Rover LR4 vs the Lexus GX460 vs the Mercedes GL450 after the jump.
