Come one Carwow, after so many tug of war episodes you still didn't get it?
It's the weight of the car which is (almost) the only diciding factor! (Tyre grip and number of wheels are second, but weight is by far the number one factor!)
My advice for a nice video is: put 2 tons of weight onto any pickup (Nissan Navara, Toyota Hilux, VW Amarok,…) and your Merc G will have absolutely no chance! (It is clear to me, that with a 2000 kg of weight any pickup will be overloaded, but for this short test it should be fine. The only factor has to be the weight difference between the 2 cars. The bigger the difference the better).
Try it and you'll see!
P.S. It would be more entertaining to put 2,5 tons into a Suzuki Jimmy! 🙂 But poor Jimmy. I doubt it would survive this without any permanent damage. (2,5 tons because I would recommend a weight difference of 1 ton between the 2 cars)…
