I dont regard that test track as requiring any extra ground clearance. A standard Jazz would do just as well there if you are willing to drive it like you stole it. Or like a motoring journalist.
I can understand the desire for a bit more ground clearance. But In my experience , as long as the front skirt has a reasonable amount of clearance, and the nose of the car doesnt project too far forward of the front axle, reducing the 'approach angle' , the the track has to be absolutely appalling before you need extra ground clearance.
As long as you drive at an appropriate speed.
A bit of extra ground clearance might occasionally save you from grounding the car but the rest of the time it can encourage you to drive faster than you should and on ever worse tracks. Extra ground clearance doesnt reduce the battering your tyres and suspension takes. They are still subject to Newtons law. Kinetic energy increases by the square of velocity. Increase your speed from say 5 mph to 10 mph you dont just hit potholes, rocks etc twice as hard, its 4 times as hard.
I have travelled some awful roads in India. You quite often see rugged ,large , off roader 4x4's having roadside repairs to their suspension yet the many small hatchbacks manage the same route without problems.. But maybe driven with a bit more caution.
