I thought Tesla superchargers have faster charging speed? They have 150kW charging, is Porsche doing something better?

OP said Taycan is the new Model S, I think that your comment vs. mine highlights that this isn't true -- Taycan customers are not the same as Tesla customers. Tesla customers get a good bang for their buck -- speed, range, charging network at a cheap price. Porsche customers get brand, design, & build quality.

Someone who values what Porsche has to offer probably was never interested in a Tesla.

Meanwhile a Model 3 Performance -- the same speed as the Taycan -- costs $90,000 less.
