Robert Cumberford's boat tail

Recently,trained designer,Robert Cumberford,critiqued McLAREN's Speedtail in AUTOMOBILE Magazine.
In the article,Robert mentioned an urban car project he was involved in 40-or so years ago.
The car was 11-feet in length,with a Cd 0.203.
With a 6-foot tail,it was Cd 0.16.
Reminds me of the Morelli/Pinifarina CNR 'banana' car of 1976-1978.

Very futuristic it was. Does not look nearly as odd now as it must have then.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

"Reminds of...."

From the cardesignnew link:
First seen Turin, 1978
Designers Alberto Morelli, Leonardo Fioravanti and Antonello Cogotti
Length 4,320mm [14.17323ft]
Width 1,675mm
Height 1,335mm
Wheelbase 2,555mm
Drag Cd 0.172


Doesn't sound like an exact match

So, 17ft for the lower Cd?

Yes.I think the long-tailed body without wheels was Cd 0.170,and they made bread slices,cutting the length down as Cumbeford did on his,finally reaching a 'production' length target,with only a slight drag increase,@ Cd0.171.
When they added wheels the drag shot up to 0.35,and they had to spend a lot of time with the cooling system,wheel areas and aspirated rear bumper,to get it down to Cd0.203.
It was amazing in 1978.

I was thinking of something from more than twenty years ago. Thought he was retirement age then, ha!
