Speed vs. MPG charts (post 'em if you got 'em)

These are old but probably the best controlled and calibrated data for 2nd generation Prius, courtesy of Wayne Brown:

Here`s how it goes when there is no BSFC included.

I was in my buddies corvette ZR1 the other day (91 guys... not the new one...) and it is gears even higher than this. It is interesting to know this though. Some states have legal speed limits of 70+ mph where most people travel 80 mph to keep up with the flow of traffic. It is interesting to know a Zo6 corvette gets about the same gas mileage as a honda insight going 80. Not everyone has the time or desire to go 26.4 mph to acheive maximum fuel efficency, so it makes sense they buy the proper car for the speeds they travel on a regular basis.

I wonder what a lower model corevette would be like?

Say what?? Might want to have a second look at the graph. On the speed axis, both km/h and MPH is shown. Make sure you're looking @ the right number!

Insight II @ 75 mph = 36.5 MPG (link to post)
Z06 Corvette @ 75 mph = 25.8 MPG

@MetroMPG -

The Vette is still ridiculously fuel efficient for being a 505 HP ICE car. Gotta love light cars!

Don't know how I missed this thread for 2 years. FWIW, my family cars in my graph in the initial post in this thread are:
2006 Hyundai Elantra GLS with 2.0 liter engine & 4 speed AT
2002 Nissan Sentra SE-R Spec V with 2.5 liter engine & 6 speed MT
2006 Scion xB with 1.5 liter engine & 5 speed MT

Here's one for my xB in a different format. I've used the same graph in a number of posts.


And here's one for my SE-R

Nope, it just wasn't in top gear yet (or torque converter lock-up - whichever).

No problem. Still dont remember how to do it even there are instructions somewhere here. Its easier to post links...

Here's mine. This was for a 2004 Chevy Aveo AT rated at 23/31/26.

The results of testing I did with the user "Slowbro". The car was stock with zero modification besides adjustments to "the nut behind the wheel". Scanguage was helpful too. The car is rated at 21/31 mpg with 24 mpg combined on the U.S. Department of Energy's website. It is an automatic 2.4 liter 4 cyl. Honda Accord ex coupe.

Here's an overhead view of the .8 mi length of road the testing took place on:

Here's some weather data for the location of the testing: Past Weather for Maple Park, IL Records Averages

Testing took place around 8 to 10 pm, I am unsure of the exact temperature or windspeeds.

Here are some individual numbers:
The number in parenthesis is the recalculated average but the number not in the parenthesis was the number used in the graph. We hadn't realized we had an extra 55 mph run until after the graph had been made and we're not exactly excel pros so we left the graph as is


The test was kind of a spur of the moment thing, not to say that has an impact on our data collection, but we were not as prepared or serious as we could have been. The scanguage has only been calibrated to the tank once so we could be overestimating/underestimating. All-in-all it was like a practice run to get used to the testing process. It was a lot of fun, and I look forward to future tests with potential modifications. Also thanks to Slowbro because there is no way I would've been able to do all the math involved in our test. Also another thanks for getting me started on hypermiling.
