Great Wall has released one picture of the new Wingle 6 concept that will debut on the Shanghai Auto Show later this week. The Wingle 6 previews a new large pickup truck that will be launched on the Chinese car market in 2014. The market for large pickup trucks like the Wingle 6 is growing fast because the vast Chinese countryside is getting richer by the day. The Wingle 6 will be just over five meters long, power will come from a 2.0 petrol or a 2.4 turbodiesel.
