2.4 liter power with A/C on

My car has a serious lack of power with the A/C running. I have the 4 speed trans. It seems like I almost have to floor it from a stop sometimes just to get it going. Is it just the nature of this engine/trans combo?

I haven't driven a 6 speed 4 cylinder. Is it any better? Anyone here with a LS 4 cylinder/4 speed have this issue?

With the A/C off it runs much better so I'm thinking that if I complain to the dealer, they won't or can't do anything about it.

Any thoughts?

Unfortunately sluggish is the nature of an underpowered car with such widely spaced gears.

Honestly though, the A/C probably only eats up about 10hp when it is running... it's not that big of a deal.

Also, I didn't know that the 4cyl/4spd was still available in '10.
It would have been nice if the Malibu had the same version of the I-4 that the Buick Regal has with Direct Injection and over 180 HP.
GM is trying to push Buick as a "premium" brand and giving them all the upgraded engines with things like Direct Injection and turbocharging.
I always feel my 4cyl car is overpower and the gas pedal is too sensitive: every time I touch it, the RPM jumps up to upper 2000 immediately.
That is b/c of the lovely electronic throttle. The gas pedal is just a glorified pressure sensor that sends a signal to the ECU "More gas!". The days of wonderfully controllable throttle cables are over.
