To which car/picture are you referring to here?

The perfect 2:1 ratio..... and completely hideous.

That is the perfect opposite of a Golden Ratio design

The canopy is the same height as the body
The hood and trunk are the same length
The wheels are half the height of the hood

Moreover its how those proportions flow, which is the hard part of Fibonacci curve to understand. The idea is a geometry that repeats itself in a progressive manner with a multiplier equal to the first proportion. This cant progress because its 1to1, all over.

Now make those wheels twice as larger- chop the canopy in half, move the canopy back, and in my eye you got a pretty design.

Spot on Q&C. That's what I was referring to. Personal taste. Anything aquatic, like a nautilus shell turns my stomach. I understand the mathematical elegance but it ends there (for me).

Boy they dont call you guys Cake Eaters for nothing.

You are very rare, in that you can admit you dont like something and appreciate its beauty to others. Or as in this case, some misgiving in yourself. Others do the opposite, they see it as a misgiving in others, instead of themselves.

The Lambo Muira. It has very good golden proportions.

This is the early split window that parked behind me at a local cruise in a couple months ago. Gel coat was cracked in a million places but the lines of the car were just 'perfect'. Being totally unrestored just made the design pop so much more. I hadn't seen one in the flesh before so it really impressed me how good the design was.

Sorry for the crappy picture angle.

Dude that's not the golden ratio.
According you your own measurements, the hood would be the sum of 1+2.
Golden Ratio is NOT the rule of thirds. That's something you invented up 4 posts ago.
Look up the formula. https://en.wikipedia.org/wiki/Golden_ratio

But before you do, do you see whats obviously wrong and correct in your measurements: All segments are equal. Thats the opposite of Golden ratio.
Thats why this thing looks so ugly, not unlike the Porsche where the back could be the front and vise-versa.

Equally importantly, you cant draw a curve through your segments. Like in the picture of the AM posted earlier.

Posting the picture again. You can see no segment is the same size as the other. Thats the point! In your example all segments are the same size as the one next to it.
(also this is directly from the Am site, so its a very good example of Golden Ratio)

cee jay, you have it. now to get back to the discussion take the following measurements.
measure the percentage of wheel height vs door, on the Aston, Muira and your silver car.
my hunch is that it will be 0.68% for the cars that look good

"0.68%", so basically 1/150th? That'd be about one-tenth of an inch on an average car.
But I digress........ take any ratio you want from any arbitrary position on any car and find whatever ratio you wish. "Door Handle to Fuel Door". Wiper post to hood emblem? Or, maybe front edge of the rear-side window to the leading edge of boot lid? Pick whichever ones you want.
Regardless of ALL of this-and-that, the first Maserati you posted is horrendous no matter which numbers you assign to any of it. That AM is OK, but nothing special.
I think you could have picked MUCH better designs to attempt to prove the point you tried to make.

Safety regulations is the other problem these days. This is from an interview with Ian Callum which ties in with another recent thread:

The most recent of those concepts is ALC, the Aluminium Lightweight Coupe, which made its debut at the Detroit show in January. Callum confirms that it is a preview of the new XK. Its similarity in profile to an Aston DB9 is a reflection of modern safety legislation, he says.

“If you take the set of rules we work to, by default you end up with the same profile. It’s inevitable.”

I suspect the wheels on all those cars have a multiplier of 0.68 to the door.
The AM is the best example because people who live and breathe Golden Ratio picked it https://www.goldennumber.net/aston-martin-golden-ratio/

Why you find something horrendous may be a different subject. That Maserati Zagato was the Star of the show at the museum of the finest automotive art.

BTW, By finest automobile art ever, I mean the Ferrari 250 GTO was the least interesting thing there. The Maserati Zagato was the work of gods. Perhaps the picture means nothing to you because you dont have a physical reference. Its a very small car, and yet has twice the space on the inside as our car. That in itself is very attractive. There was something magical about its proportions.
