A filipino, Erwin Angala was head designer of the 2008 Cadillac CTS

From a ny times review of the said car

Styling is certainly subjective, but to my eye Cadillac has done a
fantastic job with the 2008 edition. The biggest issue for designers
of sedans is striking a balance between sex appeal and practicality. A
sedan must be useful, and design freedom is constrained by targets for
mundane requirements like hip room and trunk volume. That trade-off
took its toll on Jaguar's newest sedan: somewhere between the C-XF
concept car and the XF production car, its shape turned a lot more
practical and a whole lot less exciting.

In the case of the CTS, it looks as if Cadillac loosened the reins on
practicality a bit and let the designers have some fun. A good example
is seen in the bold flare of the fenders. If the body itself were
wider, the car would have more interior volume, but it would lose the
alluring Coke-bottle shape that makes the fenders appear to have been
stretched down over the wheels, tight as a swim cap over Ben Stiller's
ears.

I'd like to imagine that sometime early in the CTS's creation,
designers were overheard debating those fenders. As they considered
widening the body to gain two inches of shoulder room -- but losing the
effect of the flares -- a cooler head intervened: "Shoulder room is
boring! Now make it with the flared fenders or I'll have both of you
testing cup holders in the Arctic Circle!" Surely the design didn't
unfold exactly like that, but whatever the case the CTS has its
priorities in the right place.

The rest of the body is no less expressive. The front end, with its
scythelike headlights and leering grille, is downright evil-looking.
If this new CTS were in a movie, it would definitely be driven by the
bad guy. The center brake light doubles as a subtle spoiler atop the
trunk lid, a nice touch. The vents on the front fenders are a styling
cliché these days, but they're a minor demerit on an otherwise
compelling design (and at least they are functional).
