I’ll admit it: that first steep-ish ascent on an off-road course on sand dunes looked pretty easy. I’ve done plenty of off-road drives in the UK, so how can driving up a sandy hill be any harder?

But as I slid back down the slope for the third time, I knew the dunes were presenting a different challenge. The alarm bells should have been ringing in the car park when we were told to let down the air in each tyre for a full 60 seconds, after which we were told it wasn’t enough and another 15 seconds' worth of air needed to come out. This was not going to be your normal off-road drive.

And so to driving on sand. We’ve all seen the videos on YouTube of people conquering the Big Red Dune in the United Arab Emirates; it looks spectacular, but how hard can it be? We were in Namibia and driving the new Toyota Hilux across a whole series of large dunes for our experience to find out.

Quite quickly it became clear that you need a run-up and some momentum in order to conquer any steep sandy dune ascent. The Hilux has a low-range, all-wheel drive transmission that needs to be engaged if you're going to have any success getting over the brow of the hill; set off in second gear and quickly into third before plenty of revs to get up to the top.

Then, when you’re at the top, remember not to panic; you’ll probably only see sky, and thus be inclined to slam on the brakes - at which point you'll lose all of your momentum before you've fully conquered the climb. Yours truly is speaking from experience here, so instead, ease off the throttle but keep your momentum so you can shift into first gear in order to start an ascent as steep as the climb you've just finished.
