Wondering if anyone knows the top speed of the 2005 Prius? I've had mine to 93mph and still had plenty of pedal left.

This has been tested and reported in one or more of the Prius discussion groups.

The Prius is limited to about 104 MPH by its programming (to limit the RPM of one of the Motor-Generators). Its actual top speed varies with the State-Of-Charge (SOC) of the traction battery since the ICE only has 78 hp to overcome the wind resistance.

I was doing 90-99mph on the I5. This was kind of scary since the prius doesn't feel like it is stable at that speed. Wished I had some low profile tires and a BT brace. Wonder how that would feel at high speed. And oh yeah, its struggles hitting top speed at 90 plus

Hmm.. that's weird. My car was completely stable at this speed (90-100+), in fact my sister said she couldn't even feel how fast we were going as we were trying to hit the higher speeds. For my 2006 Prius, it struggles more getting up from 45-65 than it does after 70. At that point, any acceleration faster seems to be "easy" on my car. Are you over inflating your tires by chance???

Saturday, when I was listening to the Blue Collar Comedy channel on my Sirrius radio, I noticed that the car was feeling very stable and and it seemed to be more quiet than usual. I looked at the speedo and and I was passing through 95. Holy-Moly! It scared me half to death. I took my foot off the gas pedal and started to slow down. When I got to 70, I started thinking. "Hey, 95 mph and it feels better than it does at 70." I guess my point here is that you could probably run at 80 mph all day with no problem, except you would have to stop a few more times for gas.
