I saw a Hyundai the other day that has these recessed door handles and I remember the reason Tesla gave for them is that they improve aerodynamics, and therefor 'fuel' efficiency... but I wonder if the weight from the additional motors and such needed for these handles negate any gains seen from improved aerodynamics?

Check your fuel economy driving with the windows cracked, and then with a bag of sand in the trunk. I’d bet on the windows being less efficient.

Good point, though I would be surprised if well designed handles would really cause that much drag.

I've obviously never tasted this in a wind tunnel or anything, I just don't think the mileage gained would balance out the lives lost.

I think i remember reading the handles gave something like 0.5%-1% extra range, but it's been a long time since I looked into it.

Back then when they started doing it, eeking out every single % was pretty important. I'd say its less important now as things have gotten more efficient and batteries have gotten better.
