VW ID.3 is designed by a Chinese team in China, built in Shanghai backed entirely by the Chinese ecosystem.
You need to be totally blind to consider vw being able to design & produce such a car on its own. let's be straight - the software in the car is not something Germany can build on its own. That 20 years gap won't be filled overnight.
All the control modules for the German model at least are manufactured by Bosch and Valeo in France and Germany - where the software is also produced.
As an aside, Bosch produces control modules and the underlying software for just about every western car manufacturer. 80%+ cars sold worldwide use their traction control system for example so I'm not sure where this so-called gap is.
It is made by SAIC using their factory and EV platform - it was just cheaper to outsource it and meet the deadlines and pricing.
Chinese can't either. BYD is a joke. Zeekr is close, but still not quite there. Soon they'll be unstoppable tho.
ID.3 is a MEB car, its production started in Zwickau (Germany) in November 2019, two years before it even arrived to China, and one year before the SOP of ANY MEB car (ID.4 was the first one) in Anting (Shanghai).
