If you asked us what the main difference between the 2011 Chevrolet Aveo and the 2012 Chevrolet Sonic was, we wouldn’t tell you about the new 1.8-liter four-pot or the new 1.4-liter turbo. We also wouldn’t mention the optional six-speed automatic transmission. Likewise, we wouldn’t be talking about the revised looks either. No, if asked what the biggest difference between these cars was, we’d be telling you that while the Aveo’s biggest selling point was its bargain-basement pricing, the Sonic sells it self thanks to its fun-to-drive and well-mannered driving character. You should only need one guess to figure out which approach we prefer.
