2014 Cadillac ATS coupe—ATC?

Move over upscale German compact luxury coupes, there's a new ride in town.
It's just a matter of time before Cadillac's newest star, the ATS sedan is given a coupe sibling. My version, above, is not the all-out dramatically styled geometric paragon of haute couture as is the larger CTS coupe. This ATS coupe, or ATC most likely, is a bit more "practical" in appearance, more akin to the 3 series, A5 and C Class coupes. Gently rounded lines first seen on the sedan are gently becoming the new Art & Science norm, with proportion and stance as much a part of the brand's DNA as is the overt angularity.

Update:

One of the great commenters over at CarSpyShots.com's Photoshop section, where I have been posting my car chops for years, suggested I increase the glass area of the coupe a bit. Since I had raised the beltline from the donor sedan, I lowered it back to production height to see how it looked. I'm torn. I always like my original intention, but I have no problems at all with the increased glass. I think it looks quite fetching, actually!
