Added curb weight should improve coast down speeds of the 3g prius assuming all other variables are the same.
There is a downhill grade of the interstate near my house and if i drive my mustang to 62 mph and allow myself to coast down until the next offramp, I will see 58mph.
This same distance, with a full tank of gas and about 200lbs in the trunk, will coast down and see 61mph the at the end point.

Hi Zonker,
Good Point. I had not been thinking about that.
But, the 2nd Gen was pretty consistent down the highway hill. The things that slowed it down was a good head wind, heavy rain or weather below 32 F.
The 2nd Gen weighed 2890 lbs (if I remember correctly), and the 3rd Gen is 3042 pounds according to the Toyota website.
I have the same stuff in the trunk of this car, as was in the trunk of the last one , minus the box the cheap socket wrenches were in. The box was mashed up good in the impact.
So, based on weight, if the drag was the same, the 3rd Gen should be coming down the hill the same or faster. Its not. With the 2nd Gen is was common for me to have to hit brakes to avoid hitting the car in front of me. With the 3rd Gen, I have to goose it to keep from getting hit from behind.
It could all be tires. But, in the meantime I want to investigate Aero.
