Looks may be deceiving. The Porsche 911 has a coefficient of drag of 0.33...the Taycan has 0.22. The Model 3 clocks in at 0.23 so if you're talking about Taycan versus Model 3, very slight edge to the Taycan (but a huge difference in price). You want laminar flow to achieve low drag and my guess is that the front of the 3 is very good at creating that flow across the rest of the car. I know that's why the 3 has flush door handles - it keeps air flow steady.
