EPA Fuel Economy Estimates

[Coolhandmike]

I've got an 07 Yuk 4x4 and with my last two tanks I'm getting about 13 mpg in the city and close to 18 on the highway. I'll have to try using cruise more often for trips.

On my recent road trip from Chicago to New York, my 07 Denali averaged 14.6 mpg at an average of 75 mph. City driving nets me an average of 10.4 mpg here at Chi-town.

I have owned lots of cars in my time. By far, the EPA estimate for my 2007 Tahoe has been the most overestimated gas mileage of any car I've had. The original estimate for highway driving in 2007 was 21mpg for the 4x4 version... this is only attainable by driving mostly downhill on a long trip. What a joke the 21mpg estimate is. On all of my other cars that I've had, I can achieve the estimated EPA MPG pretty easily on the highway.

couldn't agree more - for fun I did a "grandmother test run" on the highway (60 mph tops, uber-slow accelerations, 1/2 mile coast to stops) - received many middle fingers, and 18.7 mph.

At least it was worth the middle fingers, eh?

it was nice to be noticed

-going to try another 50 mile trial run - this time no breaks and 55 tops - wish me luck

WHY? You and I both know that you will not achieve the 21mpgs. So why bother? And even if you will with 55 tops, ................. will you start driving like this every day then? Most likely not, so why does it matter?

EPA is part owner of GM. What do you expect?

sorry I was "having a laugh" as the Brits would say - not really going to do the uber-grandma trial - sorry to waste your time reading my foolish post.

I know I'll never get there on mileage. It's hard to keep the foot off the pedal with the 6.2L. I made a round trip from Grand Rapids to Detroit with the cruise set at 76 MPH. I drove it fairly easy to see what I could get for mileage. Average was 16.9 MPG hand calculated not trusting the DIC. The DIC showed that I got 18.2 MPG.

set your IDC to show "instant mileage" and V8/V4 mode.

once you get used to keeping it in V4 mode, your MPGs will go up.

A positive post by me for a change.

I've been driving around town following your suggestion for about two months, and provided no one is behind me, I've been accelerating slowly and coasting when coming to stop signs or red lights. I have to put an emphasis on "provided no one is behind me". My miles per gallon driving average has gone up quite a bit.

O.K. I've been positive enough for one day.
