in this pic we can see which of these 5 concepts made it to production...The Evoq on the bottom right(XLR) and the Vizion in the top left which went on to become the first gen SRX.
Im going to go on a limb and say that maybe at the time the Cien might have been too extreme of a vehicle for the Cadillac brand. At that time. Now would a great time, being that Lexus just ended production of the LFA, the Cien would be perfect to fill that void.
Even though most of Cadillacs concepts are pissed away, we DO see a lot of design cues trickle down to production vehicles. Although not as extreme.
Lets not forget about the Ciel Concept...

I think Cadillac has something big on the horizon.

..... about the handling, long wheelbase(short overhangs)=stability.
@Coach E. No
... I think the Cien would've been more of a death trap versus the Sixteen
