Both of those were based on the Ford Sierra

In the article they say that the coefficient of aerodynamic drag was from CAD.
I would speculate that they meant to say CFD.
According to Mercedes-Benz's Dr. Toby Woll,Direct Numerical Simulation in their supercomputer will render a Cd which is within 1% accuracy of a full-scale wind tunnel model.
If DNS was performed for the Probe X,then their Cd 0.15 ought to be accurate.
Hucho showed us half a dozen ways to get Cd 0.15 from 1981.It shouldn't be much of an issue.(if we keep mirrors off the things!)
Here's GM's 1983 Aero 2002,Cd 0.14.Similar,with truncated Kamm tail.

Volkswagen's 1981 truncated-tail 'Flow' body,Cd 0.15

From aerohead's link:

"It should be noted that this concept was developed and executed a full six months before the Volkswagen L1 concept was premiered at the 2009 Frankfurt Autoshow, and nearly two years before the VW XL1, which bears more than a passing resemblance to our humble attempt to claim the title of the world's most aerodynamic sedan."

Ha ha ha! Tying in with the thread on cookie-cutter cars, the two vehicles couldn't vaguely resemble each other because the laws of fluid dynamics in our atmosphere are immutable and unchanging? No....

Also, there's the little issue of VW actually building their concepts and making a limited-production run of the final version. If you want to be taken seriously, Ford, get off your collective a** and give us a real car, not a theoretical rendering.

Note that this is not Ford's work, but Cunningham Industrial Design. They did many of the props for GI Joe:Retaliation in 12013. The HISS tank and the Cobra helicopter among other things.

The CFD analysis is just the cherry on top.

They might have mentioned Volkswagen's Cd 0.159 1-liter car of 2002

And their Cd 0.15 ARVW of 1981

True. I was aiming more at their implied claim that VW had copied their work, but aside from that, Cunningham wouldn't build the real thing anyway I suppose.
