Bentley EXP 100 GT

she's a 'looker'

So far, Volkswagen-Bentley haven't released ant drag data for the EXP 100. Perhaps that will change. If they have these digital images, then they have the point cloud, which is what the CFD software would need to do the numerical analysis.
ROLLS-ROYCE hasn't provided any numbers for their Wraith either. It's also a fastback design.( if she'll do 200-mph, as engineers have intimated ,off-the -record, the Wraith ought to be in the neighborhood of Cd 0.315. Amazing for a R-R!)

Yay! Success!

Bruce McCall used to talk about how cars in the 1950s had grilles that looked like they lurk in the garage at night, wanting to eat something. It looks like we're back to that.

grilles

With low drag as a technical specification, the designer is forced ever closer to the 'amorphous-blob' shapes. A good thing in my book.
Since the forebody has the least impact on drag, veteran designers like Wayne Cherry of GM have commented that the nose of these cars can be used to establish brand identity.
Even a concavity on a BEV will produce zero aerodynamic penalty, as long as the perimeter radii just provides for attachment.
As they're non-ventilated, a stagnation bubble of dead air will just travel along with the car, producing a Prandtl flow sheet discontinuity of attached flow beyond it, as if it were a solid, convex surface. No foul.
