2012 Chevrolet Sonic Receives 35-MPG Rating For 1.8L Engine, 1.4L Gets 40-MPG

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.

    Pretty sweet that the 1.4L Turbo reached the 40 MPG mark but lots of people will be upset that the 1.8L just hits the 35 MPG mark! Over at http://www.sonicownersforum.com a lot of people are upset that they found the weight to be over 2800+, I sure hope the new found weight numbers and the lack of MPG numbers won't be the killer for this car. GM needs this car to succeed and its one great looking car!

    I just purchased a sonic with the 1.8L matched with the 6 speed auto transmission. I have averaged 35 MPG so far. I think on a long road trip, I will easily get 40 MPG!
