On my car, I moved the engine forward of the front wheel centerline. This allowed me to end the fenders right behind the tires - even shorter then what you show.

Then, the windshield I cheated back as far as possible, and made the cockpit only 38 inches wide at the shoulders.

Theory (hope??? Dream??) is the air from the windshield base will spill over the sides of the car and help fill the holes behind the fenders. Maybe when done I'll have a lower Cd as I kind of have two frontal areas - one kind of behind the other.

Three seats makes the car for sure wider, and wider is what is really hurting my frontal area. I gave up and made my car a tandem 2 seater.

They made streamlining cool in the 30's and I see no reason they couldn't do the same today, but make it work.

But I digress. I wish the FC Sport styling would make it into production but almost all hope is gone. Their cars just look Korean now.
GM is given credit for the TRALAND (Today's design has already been trashed and land filled) design philosophy,spearheading design obsolescence.
DuPont/General Motors structured for slow incremental changes and by the late 1920s was already concerned about 'look-alike' cars.
I believe it was 1928 when thy took a risk with their Buick Division,launching a curved-body which would earn the sobriquet 'Pregnant Buick' by consumers.
It bombed in the marketplace and GM first attempted a cosmetic disguise, while it moved to get it out of production.
The 1934 Chrysler Airflow bombed,when rushed,unready, into mass production
and is still considered a setback to aero design.
The Lincoln Zephyr had a better Cd than Airflow,but Ford Motor refused to even use the word 'Streamline' in their promotional material.It had been so sullied by the Airflow experience.
In 1963,Walter Korff was at the annual SAE Congress promoting dramatic streamlining.H.Schmude of GM's Styling Div. said (paraphrasing)," if cars were to be designed 100% streamlined, would they not all look alike,and the stylist have nothing to do?"
Sub-mariners don't argue the 'styling' of their nuclear Akula or Virginia-class submarine.
Airline passengers don't argue the 'styling' of their M-D,Boeing,or Airbus fuselage.
Most guys don't argue female anatomy.
But boy are we attached to auto styling! I think they'll milk it for all its got as long as they can.
And that's all the automakers.

The description reminds me a little of this.
