My wife and I just got back from a test drive of a Clarity Touring. The car was great, and we really liked how it drove. Unfortunately however, even though I called ahead, it was almost completely discharged. How differently does the car behave with a charged battery? We did hear some engine noise, but it wasn't bothersome. Just curious if the car is quicker, etc. with a full battery. I will say if this is the worst case scenario, we will probably be getting one. Thanks!
