I still think they're pretty screwed. Their excess capacity is crazy (1 million+).
Not to mention 1.15 million of that is in Chongqing, one of the furthest cities from the sea in China. I'm guessing transport will be quite expensive
If it is intended for European nations, then Chongqing auto exports use China-Europe Railway Express which is actually faster and cheaper than many other alternatives. There are also a northern route for Russia.
If it is intended for North and South Americans and East Asians, then the Yangtze River Golden Waterway is used for auto exports. Also the Chongqing-Shanghai direct express line and the Chongqing-Ningbo rail-sea intermodal train for land routes. If it is intended for SEA, then Chongqing can use the New International Land-sea Trade Corridor.
AFAIK, China railway express transportation actually offers better saving in both transit time and logistic expenses and also much safer and less hassle. Other routes probably more expensive as it involves both railway and sea shipping.
