Not sure about engineering.
But they build a electric-car factory from scratch in Berlin in 2 years during the pandemic.
Check how many years other companies take to build ICE or electric car factories…
Not sure how “completed” it is, but it already produced Model Y, right?
Compare that with VW, how many electric cars they are making, and how long did the biggest auto-manufacter in Germany (not a bad country for Engineering standards) took to get factories ready for EVs?
