 Exremely quiet and it handles like a sports car. Gas mileage is superb for the size and power it exhibits. I hesitated about trading in my 2005 Prius but after the first day of driving this machine I forgot all about the Prius. (If I could afford it I would still own a Prius as well.) This vehicle is the best I have driven on long trips. The seats are like sitting in a recliner in my living room. The gas mileage difference is worth the extra cost (from my Prius) to drive my Solara.
