Max MPG readout

tootallrls · 11-10-2005, 09:46 AM

When I test drove a Prius in Sept. I was amazed to see it got almost 300mpg when slowing for a stop. I recieved my new 2005 Prius on Oct. 29th, and found the best I can do is 99.9mpg. Did Toyota make a change? My highway mpg is better than my intown mpg. Does the limits change the original mpg claims? I can get 49mpg on the highway, but I struggle to maintain that in town, even with gliding and very slow, controlled driving.

No, nothing has changed. You are probably confusing the miles driven and mpg

Thanks, but I remember watching the mpg as I drove the car and seeing it go down to 12.8mpg the rising up as the car came over the rise in the road, and when I left off the pedal the mpg went to 286.9mpg.

If you test drove a standard Prius without any kind of display mod, there's no way for you to see more than 99.9. That's the highest the display goes. 300 MPG? I don't know where you saw that.

You probably need to get used to the car before you can get higher mileages. At first it'll be easier to get higher mileages on the highway because it's fairly straightforward. Just drive it like any other car on the highway, but avoid acceleration, and you'll get close to 50s.

In the city and surface roads, that's where you'll need to learn the proper technique, but it's also where you can get 60, 70 MPG depending on various factors.

Do a search for pulse and glide. It's the central technique for getting high mileages on the Prius at speeds < 40 MPH.

you really must be mistaken. Trust me, maybe you were seeing extra digits? Not sure what to tell you, be nothing has changed with the Prius as far as the fuel economy.

-or-

Toyota made a special Prius and didn't tell us and you happen to test drive it, which I very highly doubt

In town can be very tricky. Driving consistently at "in town" speeds would yeild you great results, but there are those few things that tend to put a damper on that - stop signs, stop lights, traffic..etc. The biggest killer is starting from a dead stop. The more you can avoid that, the better.

I think the biggest killer is short trips, meaning 5-10 minutes. It doesn't give the system enough time to warm up and you burn gas for the whole trip.

Curious I get mpg numbers like that on my ScanGage. I am not sure if that is how the mpg data comes from the CAN Bus having been calculate by one of the ECUs or if it derived from other information and calculated in the ScanGage.
