Yes, unions make hybrids, and this isn't even the only one on the list. Granted, the Cadillac Escalade and Ford Escape and Focus hybrids each have more American-made parts than the Volt, but the Volt is the first plug-in hybrid made here. It's a little more luxurious than its competitors, which means features including a huge onboard hard drive, rear camera, touchscreen audio system and quiet cabin keep the price up and the sales numbers down. Since consumers caught on to this, however, sales jumped from a little less than 7,700 in 2011 to more than 41,000 last year. That $5,000 price cut shouldn't hurt, either.
