i have a new EX and the 2.0l engine seems to be powerful enough to make it perform ok, but the transmission (automatic in my case) really seems to be crap. it doesn't downshift fast enough, makes the car seem sluggish at times, and could really use an extra gear to maximize the power band in the engine. i wonder why Kia didn't put the 5-speed auto in it like they did the SX? in any event, not sure much can be done about the transmission shift points, i saw someone posted a service bulletin about changing it up but since i bought mine last week, i assume that's already been done to it (sales guy said he took it to the service shop and had the bulletins done to it, no clue if he was bullshitting me or not...)
