Hi

I have a 1980 Vanagon electric powered by a 2017 Bolt EV powertrain.
Or if you prefer, I have a transgender Bolt EV

I average 80 mpge (mpg equivalent) and I can easily do over 100-120 mpge in summer at lower speed.
Details here: https://www.thesamba.com/vw/forum/vi...737&highlight=
The pop top on our van is pure crap and I hate it so much. It's an old fiberglass piece of crap with holes, crack, etc.
To add, it is 3-4 inch's to low to stand up in the van without open it.
So I want to replace this pop top by a ridgid high roof top.

You can see the problem/challenge. How to improve energy consumption with a bigger front area?
I have to improve aerodynamic for sure and it's not so complex to do better than a stock Vanagon, but where can I start?
