Imagine how much better it would be with a wider front track though.

Well your last statement is where the crux lies. Petrol contains almost 10 kWh of energy per litre - so an 80 litre tank has 800 kWh. The battery in a Nissan Leaf has just 30 kWh, plus lets say we recover another 10 kWh from braking. The ICE car can burn fuel at 25% efficiency and it still has a 5-fold advantage.
Calling something useless because it wouldn't last very long at full throttle is simply barmy. Would you say an something like an Exige is useless because at full throttle it would only last 20 minutes?Of course you wouldn't.
Something will only last as long as the energy in the tank, and this weird belief that people have that because it is an EV it's range suddenly disappears when you drive it hard, affects a petrol engined car MORE than the electric one.

Nissan made the Deltawing car and made the claims about aerodynamic efficiency, so why not ask them?
It was lower effective frontal area for drag, but higher downforce, iirc.The design of the Deltawing was more extreme with narrower front track and, I suspect, a greater weight bias to the rear. The front was very lightly loaded and acted more like a lever to turn the mass at the rear, one of the most interesting things about it was the way it made you rethink vehicle physics and dynamics. The Bladeglider is a compromise so passengers can fit into it so the front is wider, again I suspect that being an EV and having a low CoM helps enormously with roll centres so while the front will take higher loads it can still be quite narrow to gain the lower drag advantage.
This https://en.wikipedia.org/wiki/Commuter_Cars_Tango apparently drove quite well as the CoM was very low.

Why?The Vigillante and Trivette, although three wheeled, were of a similar design.

The main way is by moving the air down the sides more gently than a conventional car. The car is not really that groundbreaking.

Would be interesting to see how much the Cd is improved by narrowing the front track.The Vigillante and Trivette, although three wheeled, were of a similar design.
A few years ago I feared the electric future, it just meant that no longer would I be able to do one of the things I love to do most, drive for fun. The first attempts at electric revolution (Gwhiz etc...) did nothing to quell those fears.
But cars like this and the insane hypercars that harness electrical power, in addition to stuff from Tesla give me hope, maybe one day we'll all turn up to track days in machines that will run all day on a charge and give us access to cheap reliable performance and open so many new configurations to designers that stuff we have never thought of could be possible.
That said, my NA MX-5 is staying until this interesting future arrives and maybe beyond.

Take an Exige and shrink its fuel tank to say 12 litres. Its now significantly compromised. A fuel tank that small is effectively what an EV sports car has. Probably enough for one lap of the Nurburgring but not two.

I could quite happily live with my Elise having a 12 litre tank if I could refill it in my garage overnight for about a pound just by plugging it in.
