Computer accuracy results???? by hoopitup2000

You may want to compare your computers mileage results to what you get figuring it out with a calculator the old fashioned way. Many cars I have rented returned a higher number than what was actually true. I have "never" acheived 46 MPG in 3.5 years with my 2005 manual. The 2005 is 140 lbs. lighter and smaller than the '09. I doubt the '09 manual would outdo the '05 with basically the same drivetrain. The even much lighter Echo is the only Toyota gas only car that can achieve those kind of numbers.
 
You may want to verify your odometers accuracy also. Mine is off almost 2 miles every 100 miles.

48.8 mpg by slowlearner1

Filled up my first tank and headed home on interstate driving on cruise at 60mph. This was over 90 mile trip and was the car readout. Even if its not 100% accurate, I didn't expect this. I've always been at or a little above the stated highway mpg...but this is way beyond what I expected. We got 42.3 on the first tank combined city/highway. I may have picked up some habits driving the Prius 2 1/2 years...but this is great.

Just because one person has never achieved a certain mpg does not mean that another person cannot. People drive different speeds and under different conditions.

Trust me, I know how to get the maximum mileage out of a car. I've driven this car under all kinds of conditions; at the most efficient speeds. I even know exactly how inaccurate my odometer is. No car is going to get tremendously better "highway" mileage than the EPA says it will get. All I was saying is to check the accuracy of the computer. I know from experience that they are not always accurate. For example,I once rented a Chevy Malibu with a 3.5 liter V-6 (automatic) and drove 900 miles in one weekend. The route was very mountainous; and we hit a "lot" of stop and go traffic. The air conditioner was on for most of the trip. The trip average showed up as 35 MPG on the computer. Would anybody in their right mind believe this was possible?? ? Not me.

What do you consider "tremendously better"? My current car is EPA rated 29 mpg highway, but I can easily get upper 30s, and sometimes break 40, when crusing under ideal conditions: little headwind, mild temperatures, and speed no more than 65 mph (it does best at 55-60). It will do mid-30s under much less ideal conditions. But I agree it's a good idea to check the accuracy of the mpg computer with manual calculations, just in case there's a big difference.

Tremendously better for Corolla highway ratings?????? by hoopitup2000

Under the newer EPA ratings; above 6-7 more MPG. Under the older ratings; above 2-3 more MPG. Slowlearner1 was indicating 11 more MPG. That is tremendous IMO. Some people may be misled by unrealistically high numbers and think the Corolla is capable of Hybrid like results. Not gonna happen. You'll need an Echo, Yaris, or Prius to get those higher numbers. The Corolla is too heavy for 45 plus MPG.

I did not intend to imply that one should expect to get 48mpg on a regular basis. I did get 68mpg once on my Prius...but on average got about 48 in winter and 52 in summer. I haven't had the Corolla long enough to get a feel for what average I'll get, but I wanted to let people to know that under certain conditions it is possible to achieve high mileage. Our first tank did average out to about 42mpg using the dash mpg avg. That was city and highway...so I don't think it is so hard to believe it could be 48 driving slowly on the highway? Let me tell you, everybody was passing us. All I can say is that I'm extremely happy with the Corolla.
 
Also, I must add that I use safe hypermiler techniques...like coasting downhill.
 
I'm not trying to mislead anyone. I did get 48.8 and if I can, others can too under similar circumstances.

My 09 is pretty new and the hwy mileage is running at about 42+ on decent hwys, flat surfaces, and 32 lbs of air pressure and doing between 60-70 mph.
 
Confirmed the old fashioned way When I decided to check it I even used the same pump at the same station...NO TOPPING OFF EITHER!
 
 (the station is only about 1/2 mile from the hwy ent/exit).In the city it only it gets about 27 MPG(I guess where the EPA rating is) I LIKE IT! The difference would buy a bunch of Prius' for me!

Was just reading these discussions and thought I would share my experiences in my 2009 corolla le, I have been posting about it at ecomodder.:
 
  
 
Posts: I have had my 09 corolla le for about a month now....best mileage I have gotten is 49, it was hilly terrain and so I purposely coasted down the hills and stayed under 2500rpm to climb them.
 
average hwy miles is 44
 
when my wife drives it , she averages around 38...she does not try like i do.
 
anyway this car seems to far exceed the epa ratings....I am guessing that anyone who just remembers to coast down hills will get in the 40's
 
I have not even read that much on the different techniques used by ecomodders yet but I really enjoy seeing what I can get.
 
btw mine is an automatic and we have been in a heat wave here since I got it, so all these numbers are with the a/c wide open

Posts: 4 just an update, still at around 44mpg average, I got 47 on the way to work today, I have been experimenting shifting in to neutral down long hills, this helps keeping my speed up while eccomodding but does not seem to help in overall mpg, I guess the corolla does the fuel shut off thing when coasting in gear is the main reason......it really seems like a 5 speed would have made this a 45mpg car without even trying.....also of note is the excellent scan guage feature....if this car had a small electric assist on take offs and climbing hills then I would easily be getting 70 to 80 mpg.....makes me wish I was a mechanic....there is definitely plenty of room in the trunk a mod like that.

Posts: 4 well it looks like I am doing this thread myself lol...one more update though, increased my tire pressure to 40psi today...up from 35, result on the drive to work today was 49mpg vs the 47 I got yesterday. I am coasting as much as possible while trying to keep my speed up to at least 40 so it looks like 49 may be the best I can do. Happy but wanted to break 50

gizzer 277,
 
Just curious how the computer readout compares to your own calculation??? The 42 plus sounds great!!. I'd take the Corolla over the Prius anyday. I've always wondered what the long term cost differences would be over 10-15 years between the 2 cars?
 
Thanks!!
