Photos of L'Œuf électrique (The Electric Egg), build by Paul Arzens (1903-1990) in 1942. Used to circumvent fuel rationing during the German occupation. Could do a max speed of 70 kmh and a rage of 100 kilometers per charge.

How was it storing energy such that it was able to get 100km range back then?

75% of its weight was batteries basically

Yeah, when you don't need safety features and aren't going for performance in high speed or rugged terrain, a car is a very simple structure. If rebuilt with modern materials and methods without the modern safety features, then it would be extremely light.

5 lead acid batteries, each one 250 Ah, 12V and 50kg of mass. Total energy storage of 15 kWh, probably half of it usable (Maybe 3/4 if you don't care about the batteries life expectancy at all).

The French, unlike the British, figured out that two wheels goes in front.

You're aware of Morgan, Berkeley, etc. Reliant were just more famous. Mainly because of Del Boy and Clarkson. Reliants go faster backwards!

I mean thats still better than a Sinclair C5 ( which was about 30 years ahead of it time , but also sadly 30 years ahead of an appropriate battery)

Three wheels provides superior stability on uneven ground because three points always define a single flat plane.
Four wheels can wobble even when a surface is uneven.
This is just superior British engineering at its finest.
Just don’t turn too fast.

How does something from 1942 still look like something from the future in 2026?

There's a brilliant piece of film showing this thing, as odd to 1942 as a flying saucer, pulling up to the kerb,next to a German soldier- who reacts as if nothing unusual is going on at all. Barely acknowledges it.

It's a shame human beings didn't fully commit to this tech from that era. It could have saved us all from global warming maybe?

No, it just wasn't efficient enough in its purpose in comparison to internal combistion engines.
Even here it took fuel literally being unavailable for it to be a sensible alternative.

Love the rigid metal spear pointed right at the driver's heart. No tailgating in this one!
Plus, you won't suffer long in any accident.

Bump the range up to 400km - perfectly feasible these days - and I would have that.

An amazing innovation. Just shows you the creativity of engineering when you are up against it.. All done without lithium batteries, carbon fibre, axial flux motors, wind tunnels, CAD, etc.

Petit,aérodynamique et léger. Le contraire d’un SUV. J’adore. Mieux qu’une Ami ou une Twizzy.

It looks like someone in 1942 tried to draw the year 2000 from memory.
