Fastest Prius

I've had mine up to 55 mph on several occasions!







...................But it was downhill.

 

See this is why I am asking should I keep it (it being the 06 Prius) or let it go. Last year I hit 145mph in my BMW M3 convert with the tach @ 4,800 RPM (red line of 7,000). I was in northern Maine with NO one around. But Man it was a blast.

Am I going to be happy with a Prius??!!

Sorry guess I am a bit off topice. Great thread.

 

I've ran mine at Sacramento raceway. It was slow when compared to most sports cars but the Prius was not designed to compete with those types of vehicles so I wasn't disappointed.

I'd have to dig up my old post about the experience but I believe it ran 17.6@79mph. Most of this seemingly slow time was due to the horrible 60' time which was between 2.6 and 2.8 seconds. That slow of a 60' time will absolutely kill your overall 1/4mile time. There was no problem with wheelspin and I tried numerous launch techniques and I could not get the car off the line any faster. It is pretty much just a "stab and go" situation.

In the end, I beat a Scion xB about 6 times but I also cut better lights than he did so that doesn't really mean anything. lol

Regardless of the drag racing prowess of the Prius, I am very happy with the acceleration characteristics in daily driving situations. Please keep in mind my prior vehicle put down 720rwhp.

 

I have had my 2008 prius for a month or so & recently had the urge to see how fast it would go. 108 mph. It hit 107 fairly quickly & the rev limiter kicked in & it eased up to 108 & stayed. I held it there for a couple miles & noticed it was still getting 25 mpg. I felt it would hit 115, maybe 120 by the way it accelerated but the rev limiter took care of that. Not a land speed record, but at least I know what it will do if ever needed. I'm averaging appx 50 mpg over 4,000 miles.

 

The typical drag coefficiency of a modern average car going only 55mph is such that a car uses half of its power, just to push air out of its way & maintain that speed. Now if you have a high mpg car like the prius, it'll likely have less power left over once 100mph is reached, so logic follows it will not be a world record setter, despite its low drag.

The salt flat rig could probably go even faster with more body mods. As kids at the drags, we even found (for instance) that by duct taping over all the space around the doors, and other areas (just to smooth air flow) we'd consistently get lower quarter mile times.

 

I've been up to 97 mph, but it was on accident going downhill.

 

Obviously being a law abiding, conscientious Prius driver I've never broken the speed limits (at least intentionally), however last year on a long drive I did "accidentally" get up to 100M.P.H on the M1 in the UK. :mod: I blame my dodgy maths - it's hard to convert KPM to MPH at 5 in the morning......

Obvoiusly I don't condone this sort of behaviour but it did seem to like driving fast :bowl:. Mpg/KM/L didn't really get too badly hit.

 

Anyone tried HKS SLD (Speed Limit Defencer) or Pivot Speed Meter V

Also, would it make any damage to MG1 or MG2 going over 108mph ?

 

180kmph is my maximum (the maximum is limited or something, here in the netherlands)
You can feel the horsepower when you accelerate, and when you reach the 180kmph, you feel that the car is limited.

180kmph = 112.5mph

 

i got ingenious and put a 50 shot of nitrous on my car and made it run a 17 in the quarter.

 

I guess it didn't help you too much if F8L can run 17.6.... ?

Personally, I'm a bigger fan of cornering prowess (tuned right, I bet Bino's car with the coilovers could do well at Mid-America). I've seen guys in Civics running rings around some very expensive sheet metal at the track.
Driver performance > cornering performance > straight line speed

 

The Bonneville Salt Flats Prius is a nice looking race car. The lowered suspension and MOON wheel discs makes the car look like a slick hot rod. People can say what they want about the stock Prius body but they cannot touch the fuel mileage !!! LOL The more MPG the better I would feel. Anyone ever hear " The race is not to the swift, but, to those who keep on trying"? Would be a good theme for the Prius. No need to get their first, but, to get their with most of the fuel still in the tank !!! LOL

 

I tell guys at car shows "I'll race any car here. 100 miles, two gallons of gas."

 

The simulator I use hints that at 133 MPH, MG2 will redline at 7500 RPM.
Assuming the ICE is also redlined at 5000 RPM, then MG1 will be doing -1500 RPM.

(the actual salt flats car uses 26 inch tires to change those RPM numbers)
