Is anyone surprised? They shouldn't be.
The Germans have missed every range, efficiency, charging metric, and date they set.

Between the battery pack, Inverters, motors, motor controllers, wiring, and electronics packaging and efficiency - a car company is coming from a severe deficit from every angle but coachbuilding. (which is important for sure) Tesla is leveraging a space programs tech and the smartest electronics minds in silicon valley.
Sandy Munroe has said for years now that when it comes to the skateboard - no one even comes close to tesla, and because they aren't silo'd they come up with innovative efficient solutions like the super bottle, that simply couldn't be invented elsewhere because of the way they work.
