Replying to: houstonrice (Oct 29, 2009 4:29 pm) It really depends. I have a 2008 Cobalt LT sedan with an automatic and I average in the high 20's. My commute is 50 miles each way with a mix of moderate to heavy traffic. I live in the suburbs of New York City and I work in the city (Queens). Because of the crazy unpredictable traffic I've gotten anywhere from 25 to 34 MPG.   If you only drive short trips that have a lot of stop and go traffic, then 24 MPG is probably pretty good. The only way to really improve is to be light on the gas and better predict the traffic ahead of you so you don't have to use the brakes too much. Accelerating from 0 or very low speeds is what really kills the fuel economy. Try to keep a constant speed. I find that I get the best MPG between 50 to 60 MPH. 65 is not too bad, but not optimal.   My auto equipped 08 is rated 22 City and 32 Hwy so I'm getting exactly what's advertised.

On that free way gently drive 55-60. Faster speeds mean more air resistance and turbulance around the shape of the car. Also when traffic slows keep your speed up above what must be 40 or a little over so the transmission is in 4th gear (the tach drops another notch); it seems in 3rd at slower speeds the economy just isn't there.   This is based on my experience driving around the area in the Cobalt 2.2 with automatic we bought for our son. At 55 or below on a level road the average hits 40. Add an occasional stop or turn and the average is 35-36. Once the car is warmed up just reset the mileage gauge and see what you're getting in various parts of your drive. The stop and go is probably 20 unless you're gently accelerating and trying not to have to stop.   Another factor might be the gasoline if it has a higher percentage of alcohol.

Replying to: cobaltken (Nov 25, 2006 5:41 am) My research tells me that the cobalt probably will not survive much longer as GM is bringing the Cruze to the states. It is built on one of GM's Opel platforms and promises to be a much better car than the Cobalt. The Cobalt (besides SS Turbo) is a terrible attempt at a small car. The interior quality is horrible, it practically rolls over on itself in bends, and the electric assisted power steering has no feedback or feel. The 2.2 is noisy, down on power, and utilizes the oldest technology. The 2.4 is a much better engine. The 2.0L turbo in the SS has direct injection, twin cam, and variable valve timing on intake and exhaust. And it produces 260 hp, enough to power the cobalt to 60mph in 5.5 sec. The Cruze will use the 1.8L that was in the Saturn Astra which is a complete dog (128 ft lbs torque). However, they will offer a 1.4L turbo with around 140-150 horse that supposedly achieves 40 mpg highway (EPA estimates) in the Cruze. Hopefully this next small car from European GM will handle like a small car should. Replies to this message: powderkegg (Nov 23, 2009 4:23 pm)

Replying to: rsattler (Nov 23, 2009 2:36 pm) I don't really understand where you are coming from. I have a 2008 Cobalt LS XFE and the car does exactly what I bought it for. In my first year of ownership I drove the car just over 15,000 miles and spent only $780 in fuel and less than $40 in maintenance (for one oil change). I did need to change the oil twice but one change was free at the dealer. The car is stylish, rides nicely and has decent features for what it was bought for; to be an economical mode of transportation. If you want a real sports car than don't buy a Cobalt... not even the SS model. Get real.
