I sat in the Taycan at a Porsche sponsored conference last year. The design feels so plain normal and boring to me. The Model 3 design is 1000% more innovative. I am convinced that car museums in the future will have a Model 3 on display, but not a Taycan.
That said, if you like Porsche, the Taycan gives you a Porsche with an electric motor. That is the only innovation I can see here.
