I've read two reviews of the Sonic now where a GM official says something like:
source: Chevy's super Sonic steps up - The Globe and Mailto quote Chevrolet product manager Harry Ng, his company “would prefer not to have any connection made between the Sonic and the Aveo."
At least the journalist is clever enough to note that the redesigned car is only called "Sonic" in a couple of markets (Canada, US, and South America, IIRC).
The redesigned model retains the "Aveo" nameplate in most of the world.
And it's getting decent reviews, from what I've seen.
Sheesh.
