I had my 02' X for about a month. I was driving it uphill today on the freeway and noticed it was very hard to accelerate it over 60mph. I didn't try to push the accelerator pedal to the floor, however I did downshift it to D4. I used to drive a Honda accord. When I downshifted it from D4 (normal driving) to D3 on the same uphill road, I saw the engine raving up immediately and output more power and I could easily get to 60mph. However I didn¡¦t see the same thing on my X and feel it¡¦s sluggish on accelerating on the uphill. Anything wrong with my X, or would that be it¡¦s still not completely brake-in (~600 mile now). In addition, what kind of acceleration performance should I expect for the X (especially compared it to a regular mid size sedan, like a 4cyl accord)? Any help is appreciated.
