I'm not pissed at Ford, just kind of sad. I totally understand why they did this, if you can't make money selling smaller cars then why bother? Car And Driver did an article a while back where they said that GM makes about $500 profit selling the $12,000 Chevy Sonic. Having a 4% profit on something that has so much risk associated with it is not worth it; as soon as there is a recall, warranty issue, or just a design defect then that $500 profit is not much. Having the cars made in the US instead of Mexico would make the profit even smaller.
On the other hand, rumors are that the profit on pick-up trucks are around $15,000 per vehicle.
Sidenote: Autoworkers in Mexico earn far less per hour than those in Europe or the rest of North America but are still ahead of workers in China and India.
I don't think the Fusion is actually going yet. Ford might be selling enough to keep offering them, and the hybrid and Energi models help out their CAFE. The US just isn't going to be getting any redesigned version.
