Graph of stock torque curve
Can anyone post a graph of the stock torque curve for an '09 2.4, automatic trans.?? I would like to reference it in my search for best fuel economy. Thanks.

Here's the plot provided by GM on the replacement 2.4 available through dealers and authorized distributors.
Because of its "universal" tune for all GM vehicles equipped with 2.4's, you'll see it's slightly derated from HHR specs, but the torque curve is within a few ft lbs.
Being that you have an automatic, you'll need to modulate the throttle to keep your upshifts near the torque peak.
