Quite a few GM Authority readers have pointed out that certain display units of the upcoming Chevy Sonic have four lug nuts while others are seen sporting five (check out the galleries to see for yourself). We’ve decided to do some digging into the issue and have come away with a very simple explanation straight from the folks at The General.
You see, some Sonics seen at North American events (such as auto shows) are actually European-spec Aveos; these will have four lug nuts. All Sonics destined for North America, however, will have five.
So there you go — pretty simple and straight-forward, right? Although we do have to wonder about why Chevy would opt for the extra (seemingly unnecessary) differentiation between the Aveo and the Sonic. We can’t imagine this is very cost-effective…
