Good suggestion about the air dam. It's a plastic part that will scrape on almost any driveway with an incline but that's harmless. You can even take the dam off if you want. You want to be making sure the body doesn't scrape.
As for the "higher clearance" claim, I think they made the standard dam a little shorter (you could get a shorter one for the first generation). But the car itself doesn't look to sit any higher. FYI if you ignore the dam I don't think the Volt sits any lower to the ground than many other cars. That's not surprising since the higher the car sits the worse the aerodynamics, and the new emissions standards require higher efficiency.
