I don't think the roofline is ugly at all. OTOH those corrugations over the wheel arches! What purpose do you think they serve, other than panel stiffening?

Thank you for that correction. |

Me too. The discussion of the C-HR has me thinking about the rear wing on the old Cosworth Escorts with it's massive extension over the back glass. Clearly the intent is a bit different however.

Looking at the overhead view, it appears the airfoil is positioned to allow a more aggressive breaking curve at the top of the rear window.
I'm thinking this might be a better solution than a Kammback for my Dasher 3-door.

Around 1992,Ford of Cologne,Germany constructed a homologation special Escort for rally competition.It had a rather large rear foil,which increased drag,increased fuel consumption, and lowered top speed;but it did improve high-speed competition performance.

Well, that's easy. Just go for downforce.

You've been busy. What are the relative merits for getting you message out, of Autospeed, your book, and videos on Youtube?
Trailing vortices and drag: You may get gentle rains and sunshine, but in the Pacific Nortwest, in a driving rain on the Interstate, you get a good view of vortexes. I like the trucks with lateral vortexes projecting out of the front wheel wells. Water has more mass than air which complicates things, but the water likes low pressure areas. 
Vortex generators: I was hoping for fads or fashions in vortex generators. A few years back it was glowing plasma actuators.

Autospeed now has nothing to do with me - it's a previous employer, no more and no less.
Books to me are 'real' (citable, criticisable, published) and conversely, YouTube videos are just fluff. I do the YouTube videos only to promote the books. One paragraph in a book is a full YouTube video!!
WRT to vortices, I think it has to be fine spray and not rain ie a mist of tiny droplets. I've driven in the US north west, and I didn't see the conditions I am describing very often.
Yes, I get emails about plasma actuators and the like....
