Unscientific, but a ~42% in a Hemi Jeep

I was able to drive my friend's beast of a vehicle yesterday. It is a 2008 Jeep Grand Cherokee Limited, top-of-the-line, decked out interior and very nice all around!

Here are the specs. It is a European website, but the information matches the American model - 2008 Jeep Grand Cherokee 5.7 V8 Hemi Overland (since mid-year 2008 for Europe ) specs review

Cd - 0.41 :eek:

We hopped in after church and headed to StarBuck's to work on Calculus (I'm the tutor :D). It was past halfway before she told me that her Jeep had a factory trip MPG gauge. I had it up in less time than the Jeep's 0-60! Due to not knowing about the gauge, it was only a 4.47 mile test run. Hardly even acceptable! Here is le root - Route Builder: custom route created on August 31, 2015

Her average over the past 7700 miles had been 12.3 mpg:eek::eek::eek: I knew that I could show her that it could be better.

I had to pass through 9 stoplights from the starting point to StarBucks. I only hit 1 at the off ramp :) I did no extreme hypermiling, just easy acceleration, coasting to the light, to backed up traffic and in the parking lot, obeyed speed limits and of course timed lights.

The end result of the short trip? 17.5 mpg

An increase of 42.3% over her 7700 mile average!

The EPA list her vehicle's combined average at 15 mpg. So I still got 16.67% over EPA combined! If I go by city mpg since all her driving is city, I got a 34.6% over EPA city :thumbup:

For a person who pokes fun at my car and my mpg, she was actually stunned and wanted to know how I did that. That is all the win needed :thumbup: we may have a convert! (one day...)

What do you mean by "convert" your friend? Making her drive more efficiently or to have her beast traded for a fuel-sipper?

There's 0 chance that she would ever trade in her Jeep, so the conversion would be for her to drive as efficiently as possible. Anything is possible when the eco-gears get to turning in a person's head though! Eventually, I may get her or her husband to go Basjoos on a civic :D

This world needs a lot more Basjoos!
