Check the sticker on the driver's door jamb (open the door and look at the door frame) — it lists the engine displacement. You can also look at the rear of the car: a V6 badge means the larger engine; no engine badge typically indicates the base 4-cylinder (I4). When in doubt, check your owner's manual or the underhood emissions sticker.
