I'll pass on both.
Other than the forward-leaning sail panel, the first one has so little on it that evokes X1/9.
I like the greenhouse on the second, but that's it. The front looks like it could be from any supercar made in the last 10 years, and the side scoops are a Boxster rip-off.
If FCA wanted to bring back the X1/9, they already have a mid-engine design that could be adapted for volume production, the 4c. Depending upon the price point they are aiming at, dump the carbon fiber for aluminum (mid-price) or stamped high strength steel (lowest price). Make the platform a little wider and a little longer to accommodate American avoirdupois, and use a warmed up version of FCA's current 2 liter four. Send Marcello Gandini the chassis blueprints and a blank check and ask him to send back a modern X1/9, and build that!
