Neil,

What's the reason for the uneven weight and passenger distribution ?
With one passenger moved further forward, the roofline could come down lower and/or become narrower near the end, reducing the size of the wake.

Within the same dimensions, you could provide more leg- and elbow room for the passengers by seating them on both sides and staggering the seats.

What I'm missing in your design is dedicated luggage space.
Having luggage laying around in a car adds to the injuries in an accident.
So it needs to be stored somewhere secure / separated from the passengers.

You don't want side-doors as they introduce weak spots requiring heavy reinforcements but the huge gap in the roof and rear will require the very same reinforcements.
Loremo did something similar, but it has a rather large structural box between the front and rear seats up to above the lower window line.

With a heavy battery pack, no matter how low it's positioned, the structure must be strong enough to be tipped over or even rolled without too much damage.
