Max speed of Prius

Best I ever did was 98.... that was in an 07 Pkg 2, it wasn't very happy going that fast, in my experience once you get past 75-80 or so the Prius isn't a very happy camper.

 

I think it depends a lot on the road conditions. I've gone 90mph recently and it was not bad at all. I regulalry make blasts up to that speed when going around a lot of crazy traffic and the car is quite stable. Must be my BT plate....

 

This was on the Jersey Turnpike. Although my personal fleet is more performance oriented so I am a bit spoiled.

 

I hear ya.

 

I'm waiting for the ZR1s to depreciate... got an XJ8 and an M5 at the moment.

I must have been driving a bad one, because once that sucker broke 80 it was wandering and the poor ICE was howling to keep up with traffic. Still, averaged 87mph and 42.1 MPG

 

Nice! on the cars and the MPG haha

 

This would make me the first person to be proud to average 42 and change on the highway then?

 

107mph...the best i did...

 

I've been to 105 to 107 twice in my touring on Highway 5. Both times were perfectly smooth and planted. One was on a windy day where at 70 it was whipped around by the wind but oddly perfectly straight and smooth over 100. The acceleration up to 100 is much better than other cars of similar hp because the torque of the MG2 is allowed out by the software more at higher speeds than lower.

 

A few days ago, I beat the 180 km/h limit. While driving in southern Bayern (Bavaria) I got my Prius up to 184 (according to the dashboard). It was an odd feeling when the engine cut off at 180 but the speed kept increasing while the MFD indicated that the batteries were getting charged.

My new GPS (a TomTom 930) indicates that 180 km/h resembles a true speed of 172 km/h. This was repeated at about 10 different times. My old GPS, a SONY, claimed that 180 equalled a true speed of 170 km/h. I'm not sure which one is most correct.

 

beautiful vette!!!!!!! i heard that the car is governed at 107 mph on the pri

 

I heard on the radio theres a celebrity that was drunk driving and he was going 120 mph and was caught by a cop. :rockon::rockon:

 

Was Al Gore's son and I think it was 100 mph.

 

Al Gore's son is correct, and if I recall his speed was about 105 !!!

Wonder what his mileage read out was?

 

Well, during my trip through Germany, my car averaged 6.1 l / 100 km and that isn't bad at all considering all the hills my car had to climb and the fact that there were two adults + luggage in the car.

 

I've earlier stated that the top speed is limited to 180 km/h (according to the speedometer of the car). I've also learned that if you accelerate up to top speed while going downhill, you can momentarily reach higher speeds, but you will eventually slow down to 180.

Well, today I learned that if you set the cruise control to just below 180 and use the CC's function to increase the speed, 181 on the speedometer is possible and this is not just momentarily. I couldn't get the speed up any higher than that and I tested this on three different occasions during the day.

 

I got mine over 160km/hr in Saskatchewan on the trans Canada. It's probably electronically governed at 160 (100mph) for north american models. I suspect that since MG2 drops in torque after 70kph and is virtually useless after 130 kph that the combined ICE and MG1 max RPMs limit the speed to about 180kph... So that might be it's physical top speed.

Though if the inverter output voltage for the drive system can be doubled, MG2 might still be able to provide full torque well into 140kph and in phase advance mode provide some percentage of full torque up to about 260 kph... but that torque will not be enough to really add any significant speed at 180 kph. So to really up the top speed you would need a high voltage (1500 volt) inverter. It would have to have triple the input current capacity and instead of hooking it up to the traction battery, you would need some super capacitors. This would allow MG2 to provide full torque up to 210 kph, that would probably up the top speed to over 200 kph, until the capacitors are drained...

But you should be able to go from 0-100 kph (about 60mph) in about 7-8 seconds. Making the prius a sports car...

 

Actually 108 mph. There is many topics about that.

Mine reached 178 km/h before hitting the governor.

 

My brother-in-law just got back from Germany where he got his rented Prius (Gen II) up to 190 Km/h. Showed me a photo of the speedo to prove it. Said his wife took the photo. I'm not sure I'd want to drive a Prius at that kind of speed, myself!

 

If you haven't changed the balance of the car with too much luggage and have decent tires with proper pressure, the car is still stable at those speeds. At 190 km/h, the Prius is coasting with the engines disengaged and will eventually get back down to 180.
