According to the EPA, the 2012 Chevrolet Sonic will receive a lower rating than GM’s optimistic 40-mpg figure. The standard model with a five-speed manual transmission, powered by a 1.8L four-cylinder with 135-hp is getting an EPA-estimated 26/35/29-mpg rating for city/highway/combined. The six-speed automatic transmission is just slightly less at 25/35/28-mpg. The 1.4L turbocharged four-cylider with 138-hp does achieve the 40-mpg rating however.
This news makes the Sonic a little more disappointing, despite its price point. Those seeking the best mpg might not even look its way, as its larger Cruze counterpart gets 25/36/29-mpg with the same 1.8L and six-speed manual transmission while the Cruze Eco with an automatic transmission gets 26/39/31-mpg. For now, the Aveo successor will have to compete on price with the base LS model starting at $13,735 while the LTZ can top out at $17,235 in hatchback form – or $17,935 for the turbocharged 1.4L.
