A car with a long wheelbase has better driving stability than a car with a short wheelbase. For such a long journey to Tibet, it is more appropriate to choose a car with a long wheelbase. In particular, the road conditions in Sichuan-Tibet and Yunnan-Tibet are particularly bad. When driving on bad roads at high speeds, the stability of a car with a short wheelbase will be worse, and it is easier to drift when turning. In order to drive safely and avoid rollover accidents when driving at high speed, it is recommended to choose this long wheelbase car for travel. It takes a lot of courage for a car with a low chassis to cross such a road. It is not necessary for an SUV to drive in Tibet, but it is necessary.
