Not sure exactly what you mean . . . but . . . my RAV4 is 4WD . . . and I haven't noticed any extra (more than normal) gas pedal pressure being required when turning sharply. The 5spd 4wd model has a differential lock button, that should only be used when on slippery surfaces or when you are stuck (or close to being stuck ;-) The 4wd automatic does not have this button . . . the differential in this model automaticly detects wheel slip and gradually locks the front and rear axles as the slip increases.
