Replying to: brucelinc (Jun 03, 2008 5:07 am) no reason to get irritated at all - it is not this statement I question - heck it was even possible to better the old EPA ratings never mind those lower 'new' ones. The disbelief comes from your mileage claims at 75-80mph specifically- given that there is a significant hit (FE wise) any car will take at those speeds. Would be interested to know for sure what that engine speed actually is at 75 or 80 - one poster reports 2000 at 75, the other 2000 at 80 - even that is a significant difference, never mind that is also less than even the Toyota engine/6 speed which does have that greater flexibility allowed by that extra sophistication in the valvetrain, as you note. And yes, if I drive my Avalon at a constant 60 or even 65 I will see FE in the low or even mid 30s - just not at 75 or 80 - and down here in Texas - I'd be getting run over if I tried to poke along at a mere 60 mph on most of our highways

That would be 74.2 MPH at 2000 RPM and 2,156 RPM at 80 - a difference of a tach needle width. I agree that those speeds take a toll versus 60. Even 80 takes quite a toll over 75. I didn't pay attention to our average speed for the trip but I usually can avoid speeding tickets on this route if I run around 76 -78 - give or take a couple of MPH. The posted limit is 70. |

Replying to: captain2 (Jun 03, 2008 6:19 am) When my wife used the car consistently, she was more like 60/40 city/hwy, the average dropped to about 23.6 mpg, as an average. I tend to drive fast, but not jack rabbit starts to get to speed. |

Replying to: thegraduate (Jun 03, 2008 7:09 am) since I know you are one of our younger posters here - I would suggest that you might also be the only '20 something' that can make this claim.

Replying to: jaymagic (Jun 03, 2008 7:10 am) which in itself can lead to inaccurate results These new high speed vapor recovery gas pumps will almost always shutoff well before your fuel tank is full - in the case of my Avalon 2 gallons or more - out of 18.5. So therefore if I start with a truly full tank and then 'fill up' with some quantity of fuel 2 gallons less, my calculated FE will necessarily be way high (approx. 10%) . The only way anymore to get an accurate FE calculation is to make sure that the tank is 'topped off' everytime - something that they (and the pumps) don't want us to do for obvious reasons. I really think that the trip computers in our cars may be more accurate  on a tank-by-tank basis.

Replying to: captain2 (Jun 03, 2008 7:21 am) Captain, were you trying to fish me out? Last time I took my IS350 on a trip I set the cruise at 85 mph and I got around 28 to 29 mpg. I have no doubt that if I slow down for just another 10 mph (75) I would have no problem brreaking the 30 mpg barrier. That's not too shabby for a 300+ hp car if you ask me... For your info, the new EPA estimate for my car is 19/26/21 and old estimate was 21/28/24. |
