Did you see the custom Metropolitan? That Elmer Fudd car is 1750 pounds. I'd want to sit in the (lateral) center for a little more safety. Modify the body, floor, etc to resemble the aerodynamics of the BOcruiser. I think it'd look cool and get good fuel mileage. It might be too small for safety.

I could do the same to my 2400 pound '61 Ranchero and feel safer, but that would probably come with a fuel mileage decrease. It might be hard to see, but I see modified Ranchero in this Mercedes prototype (the Mercedes rear would be the Ranchero front).

Or I could build a frame around Falcon doors and front fenders and a '37 Ford beam axle I have (with wide five and/or artillery wheels). That should be lightweight.

Or mimic the AST with a Volvo PV444 rear body portion as the front. Or a '38-'48 Ford sedan.

The point of a project is to have fun and learn something.
I remember that one from when I was on here previously.

The rest of your reply has good points.

Well, I was thinking in terms of side impact and frontal crash testing - cars like that don't have safety requirements of that sort, do they?

I imagine the solar car doesn't. I would do my best to build in protection.

It'd be a shame to do more than a Watson panel paint job and Appleton spotlights.



That's a unit construction body. Lighter, but modify at your own peril.

The big tension nowadays is the grounded half-Zeppelin and modern [electric] sedans and CUVs. The Metro is neither. Better to start with a Porsche 356. Or an old SAAB.

Ah, a use case. That's helpful. Ingress/egress is important. Cargo space?



Pretend this isn't a VW. It is a four-passenger vehicle with a Cd of 0.21 or better. It would do 90mph with a 25hp engine. That's down to the shape of the body, but it was nothing special underneath. Modern car like the Aston-Martin Valkryie or BAC Mono look like a full fendered car from above, but they're hollowed out underneath.

Why? You have to brace pretty much any car you chop.

Why?

I like that. A VW would be a good starting point. But they're on par with the Metropolitan as for construction. Either could be modified for a bit more protection.
