Have you seen all of the comparison reviews on youtube? All the articles in print comparing the two vehicles? Ya know like MotorTrend, Car and Driver?
The bottom line is that they're both hybrids Steve. The engineering details don't change the fact that they were both designed with the same purpose in mind. I assure you they can be compared.
The 2010 Prius has a EPA mileage rating of 51/48 while the 2010 Honda Insight has a EPA mileage rating of 40/43.
See? I just did it myself!

My 2010 Insight graphically displays its current MPG on the dash while its running. It always displays more than 50 miles per gallon cruising at 60 MPH (on level ground). I'm on the highway almost exclusively as a daily commuter.
My Insight displays its overall miles per gallon on the dash as soon as I turn the key in the ignition: 46.8 MPG
Either way, the 40/43 numbers seem off to me.
It's astonishing to me that the EPA (a government agency) could have possibly made a mistake.

I'm averaging 44.3 MPG on my 2010 Insight EX.
I have rented a Prius for as long as a week and averaged about 46 MPG. Not sure why the EPA estimate seem low for the Insight. I believe their test procedures are the same for all vehicles, but the hybrids have different modes that they can be put in. They never mention what the mode the hybrid vehicles were in during the testing.
I read somewhere that their tests require that no special mode be engaged. Don't know if this is true. If it is, then ECO mode, Sport mode or EV mode would not be engaged on Prius or Insight.
Perhaps you could take your Insight out of ECO mode for a week and see if you get results that are closer to the EPA's results. Let us know your findings.

"The bottom line is that they're both hybrids Steve. The engineering details don't change the fact that they were both designed with the same purpose in mind. I assure you they can be compared. "
They cannot be compared in terms of the design. It takes a bit of study about how they were engineered. There were some statements being made that did not match the engineering.
One can compare mileage if you like, but that does not change the way the two system achieve that MPG - which is totally different. Yes, they both have batteries and electric motors, but they are used in radically different fashion. If you are not interested in the technical details, that is OK by me, but some people are interested...

I have a camry hybrid (2008) and an insight (2010) so I have lots of experience with both drive systems. Although the pure electric Toyota mode feels very cool (like when searching for street parking and circling the block using zero gas), even with the gas on all the time, the Honda gets amazing mileage. I find the Honda takes more practice to pull really high mileage, but that said it feels like the more you try, the more it delivers. To avg more then 40 mpg with the Toyota seems futile, whereas I am at 57.6 avg over the last 14000 miles and it feels like if I wanted to I could get even higher numbers. I have to agree with those who note the EPA numbers seem wrong - but it is wrong for both cars, so perhaps it is the hybrid driving style they don't properly apply that returns these results.
As a side note, I have been amused by the dialog between you and spunjorno. You seemed spot on in your technical analysis in your initial response about pure electric use to get highest mileage in the insight, but his empirical approach delivers better milage. I tried to test using assist more to get more mpgs, but found I got much less. The reason was I had to use more throttle to get more boost. Following his suggestions, most of which I actually learned from the "Shell answer man" in the 60's, gives the best mileage regardless of vehicle. The advantage the Honda has is it's coach shows instantaneous mileage vs avg very clearly so you can set easy to monitor goals.

I heard from the dealer that when the EPA testing is done ECON mode is not used. I do not believe that the ECON mode would have that much bearing on the fuel economy.
My note is that it really makes a difference driving 50-55 as opposed to 65-70. Economy drops from 57mpg to 46mpg.

For understanding the hybrid 'psychology' of driving, seriously great analogy re the stored battery-energy being like a $5 you found in your pants pocket that you forgot was there. (but let's make it a $20, why not?)
#132 of 166 Real Honda Insight MPG
Nov 19, 2011 (11:06 pm)
So far so good with the mpg listing. I have the 2011 Honda Insight LX as a second commuter car. With the stock steel wheels and Dunlop Tires I was averaging about 38 overall with mix freeway and city.
I changed wheels and tires about 2000 miles ago to lighter alloy wheels by konig and put the bridgestone ecopia 422 tires on. Now I am getting 41.5 overall. On one mostly freeway trip to Vegas I got it up to 46.5 mpg. So unlike US brands (GMC) I think Honda really states the correct MPG's.
Great lower cost alternate to Prius, funner to drive, lighter, looks better, more front legroom (No weird Middle Console thing). But seats could be better quality.
Nov 20, 2011 (1:55 pm)
I found the front seat pretty uncomfortable for my bad spine and was not much more comfortable in the back seat on a small ride. The headrest was also canted a bit to forward which created immediate neck pain so unless they change the seats, this car is one I could never own. Also found the rear split hatch window difficult to see out of, not a deal breaker but didn't feel safe looking out the rear. A shame to because I really wanted to like this car and the stellar mpg's are just a bonus...I also did not want to get a Prius for the extra price plus the weird dash layout. So I'll keep on truckin' in my '06 Civic, which is still in great shape and tightly screwed together with nary a rattle or squeak...it does help that I am the sole driver of it 99% of the time. And besides my son coming home for a few days/year, that's the way it'll stay!
Just like you, I had changed out the stock steelies to a set of '05 SI alloys and am wondering if in fact my mpg's improved with that swap? I don't keep detailed mileage records so have no idea if this could be true...hopefully it has helped. The highway mileage ain't to bad but my city driving has been always around 30 from my quick computations...in specs to be sure but nothing to write home about but not worth it to trade for a few more mpg's.

Sandman, 30mph in city? You must drive pretty aggressively. I have 5,500 miles on my 2011 and have averaged 45 overall, almost all city. I do keep detailed records and what I calculate and what the car says is at least 2 mpg off. Car says almost 47 but that is high.
