The tail of the 3rd is close to that of the 2nd Gen Prius. Its the lead into the peak height that is different between the two cars, I believe.
donee,I've been unable to get a factory side shot of the( 3rd-gen US,4th-gen Japan),so I don't have an image of the car in true-length.Without it I can't analyze the car.
Since the new Prius has a rear spoiler,that's kind of a tip off that the backlight is a little dirty.
It also violates W.A.Mair's boat-tail architecture for attached flow.
Its 'close',and I think Prius' designers comment about being 'close to ideal' suggests that it's not 'there yet.' A standing pack of Lucky Strikes on top of the spoiler might make up the difference.
My friend already complains that at standard slope,the new Prius backlight is virtually useless as for rear visibility.
