Hey everyone, I apologize if this has already been a thread on here before. I did a search and couldn't come up with anything on the Gen.II Insight.

Owning both a Prius and Insight, on PriusChat, there's a thread with all the current mpg record holders for stock Prius' that displays model (Prius c, Prius v, or regular Prius), miles driven with that mpg average, and average speed. So far, #1 is a Prius c that drove 501.1 miles @ 99.9mpg / avg. speed 19mph. #2 is a regular Gen.III Prius that drove 1000.8 miles @ 91.8mpg / avg. speed 22mph.

There are some impressive numbers on there! Being an Insight II owner, I know the Insight is capable of some pretty impressive numbers, so lets start a thread of your personal achievements in your STOCK Insight II. :)

To start off, this is my personal best MPG. over 432 miles, on my trip from West Virginia to Madison, WI for HybridFest in July, my Insight returned 61.0 MPG. When I finally got to Madison, it fell to 60.9 because I was getting antsy. :rolleyes:

My average speed was 60mph, and I had the windows cracked by maybe 1 inch, ECON mode on, and A/C off.

....or my thread can be deleted now. I see where people already started threads about the most mileage. I don't know why it didn't come up when I did a search... Sorry folks!

We had a 10 mile contest and a few guys were honest, then a few coasted down the Blue ridge mountains. I got like 79 mpg, others who cheated shows 150.

I was king early on, but a lot of mods I did were for performance and drivability vs mpg.

My favorites was to have my mpg match my speed and distance covered.

131 miles into my most recent fill up, (last night at BP with 93 premium.) not bad! This is normal driving too. Lots of steady cruising with 30% being city stop & go.

With careful driving the prius can beat 100 mpg in its stock configuration. Its similar to the gen1 insight that can surpass 100 mpg if carefully driven.

I drove a prius 3 like a rental car and got 50 mpg, with the grill partly blocked and sidewall psi in the tires I got 65 mpg driving it like a rental car. :D Wait, it was a rental car. :evil:

That_Insight_Hybrid, that isnt bad in this weather. Yesterday or should I say 2 days ago on my normal 54 mpg commute I got 36 in a freezing rain like. Minus the rain, but same cold windy weather I got 42.

Im also using the hvac set to auto and 85 degrees. It helps to keep the windows defrosted.

egads, You never seen people drive around with just enough scraped off the window to see ahead? :)



I tried the 3 right method to defrost the windows, but seems you need the ac compressor to kick on to get the job done in seconds. Then I flip back to vent. Some days it seems I need to hit defrost every 10 seconds. Its at least a 3 mpg hit, plus it lowest acceleration.



Whats the 3 right method to defrosting windows? Turn the cold'heater to the right, the fan blower to the right and the directional control to the right.

Cobb,
I used to turn defrost on and manually shut the compressor to just use the heating system. Have done this for years with my other Honda vehicles and it works fine. Can you do this with the Insight?

Helps quite a bit to keep inside of windows as thoroughly clean as possible in Winter. It's a pain to do in cold weather but it does work.

Knocking as much snow off your shoes/boots outside the car will also help. The more moisture you bring in the car the more your windows could mist up.

I usually use defrost until any fogging is gone from windows, then back to normal heat. If the windows start to fog up, I cycle the defrost again for a few moments until the windows clear again.

I can't turn the heat up much past 68 in the Winter, mostly because I'll be dressed for the outdoors. Sometime 68's even too warm.

Rain-X and other companies make products that help reduce fogging of windows. They work marginally well.

Folks who try to save a little MPG by not using the defrost when it is really needed have issues.
I agree. ... This is especially true when you consider that the engine needs to "throw away " heat in order to function correctly.My radiator blind fits directly in front of the radiator itself and allows air to reach the radiator through a hole sized at just 4"x6" ( 100mmx150mm). This allows me to use heat in the cabin to defrost and keep me warm whilst maintaining a coolant temperature of 177F (81C) in ambients of 59F ( 15C) or less. I initially tried a blind with no hole at all which allowed the engine to maintain a temperature of 197F (92C) but I did find that I had to travel below 60mph to keep the temperature down.
In short, during the cooler weather my engine dumps its heat into the car (while my windscreen and I stay warm) rather than into the atmosphere (while my windscreen and I get cold).
Interestingly, I was looking into part numbers and it seemed to me that there is just one part number for replacement Insight radiators. This implies that Honda fit the same cooling system irrespective of expected ambient temperatures being below 32F(0C) or above 113F (45C).
For those of you who are wondering how I manage to obtain temperature readings, I use a scanguageII in order to monitor coolant temperature.

Do not, whatever you do, use RainX anti fog for the car interior in winter. It's hydrophilic and works by drawing the water into a single clear layer instead of micro droplets. That's great, until the clear layer starts to freeze. Absolute nightmare!

Socks full of silica gel? Interesting.... My problem is my windows maybe clear to drive off, then when I make a J turn at the end of my driveway as soon as I start to go forward POOF, the windshield flash fogs over on me. :confused: I just sit and wait a minute or 2 and let the running defroster do its things. Using the windshield wipers does nothing, but sometimes where the fluid sprays on the window is a clear spot.

I think the engine (exhaust manifold etc?) warms up first and releases a lot of moisture from condensation which gets sucked into the cabin air intake.

If the windscreen is clear I keep the ventilation OFF for (at least) the first few hundred yards.
After that defrost does what it is supposed to do.

Using a window screen overnight helps a lot; it makes the car and the windscreen lose one or two degrees less which makes a big difference in fogging up, and of course you don't need to scrape ice then, at least not from what's covered.
Problem is, it gets wet in the rain and/or lost in high winds. Cannot use it as much as I want to.
