I put splash guards on my car after I noticed a few chips. I hope it helps. I don't want my car looking that bad after 21,000 miles!
But a lot of it has to do with the shape of the car and sticky tires, not the paint unfortunately. The car should come with stealth mudflaps from the factory and if anybody is to vain to have them on they can remove them and deal with the chips. Go look at the 2011 Mustang. It definitely has built in splash guards to prevent this... Chevy could easily do this.
