Suddenly Cobalt Beats its Competition
By Igor Holas | 04.11.2008 | www.autosavant.net

Among all the excitement over Chevrolet’s new 260 horsepower Cobalt SS, GM made a much quieter, but much more significant change to the Cobalt lineup.


Starting immediately, GM claims the Cobalt with manual transmission to be among the “most fuel-efficient compacts on the market” with 36 miles per gallon highway. This is mostly true, as this new number beats out the Corolla (34mpg for the now current 2009 model) Civic (34 mpg) and Focus (35 mpg) who have been leading until now. However, the Civic with automatic transmission achieves the same highway mileage and better city mileage, and the Civic hybrid (of course) beats out all of them. Nonetheless, the mileage improvement is a meaningful and important improvement to the otherwise well-rounded Cobalt. Using a standard engine that is significantly larger than its competition, the Cobalt has been saddled with a somewhat mediocre 33 mpg until now. Moreover, the new mileage rating was still achieved on the 2.2l EcoTec, which also boasts the best-in-class horsepower (148) and torque (152), leaving the 1.8l and 2.0l engines from the aforementioned competition in the dust. To exemplify the magnitude of GM’s achievement, the very-much acclaimed Mazda3 with a similarly-powerful 2.3l engine achieves miserable 29 miles per gallon on the highway – a full seven mpg difference.

For years we have heard how the ECOTEC's are good only for power and suck at fuel economy. Well...not so much. This is really just the start of GM's updating to the ECOTEC's to squeeze more fuel economy out of them.

The 2009 Cobalt will have the new 2.2L ECOTEC with VVT and other enhancements, so power should stay the same (if not more) and fuel economy will rise more. Not to mention, they will also be offering an E85 option on the new 2.2L and the 2.4L equipped vehicles. The HHR retains the same MPG figures as the new Cobalt engines.

I'm surprised GM is being so adament with updating the ECOTEC's. It's very unlike them...ha. This will be good though, because 2010 will bring the all-new Cobalt and it will have a new ECOTEC engine with smaller displacement and DI.

Yes, the official rating for this model is 25/36 MPG. The 2009 Cobalt will improve upon that with the new 2.2L VVT ECOTEC, which is suppose to get 35 MPG in automatic form.

All 2009 Cobalt's will come standard with 155 HP as well, which is by-far best in class.
