The original article is in German, so here's a nice summary from Reddit.
A German engineering firm brought over 4 Tesla M3's for a tear down for an unnamed German automaker.
Some interesting highlights:
*Tesla Model 3 LR estimated to contain $18k in parts, cost $10k to assemble if production rate is 10k/wk (it's not, yet)
*The amount of Cobalt in the battery is far lower than other manufacturers, making the cells way cheaper.
*Everything very symmetrical to facilitate L/RHD production.
*Only 4 kinds of bolts used on the chassis (!)
*Many parts are designed specifically to be easier for a robot to assemble them
The battery thing explains some of the sour grapes coming from Mercedes about the Tesla semi about the proposed battery pack size/price "violating the laws of physics."
