Test Driver Ratings & Comments

Acceleration commentsOnly with a clutch-torturing 5,500-rpm launch does the Impreza leave with any kind of haste. It was pretty easy to feather the clutch due to its obvious friction point, though. Shifter cooperated with aggressive shifts and gates were obvious.
Braking ratingGood
Braking commentsQuite a lot of forward pitch, but very consistent stops. Pedal effort was low and a little squishy, but not terribly so. Good resistance to fading.
Handling ratingGood
Handling commentsDecent grip with mild understeer on the limit. There's only a slight ability to tuck the nose in by lifting off the throttle. Everything happens in slow motion (e.g. understeer, throttle response, steering response, etc.). So-so tire grip and soft suspension relegate this entry-level Impreza to an entry-level performance in the slalom. Slow responses from steering and throttle reward a "less is more" technique rather than aggression.
