Look Getshoked.ca, I would say that 90 to 100 mpg is possible, but I have seen one person on the Danniel Curran website get 134 mpg or somewhere in the 130ish. Now as for that I would have to be a little skeptical about it, but yeah, it very well could be true. The reason why I am a bit skeptical about it is the fact that only that one person got that on the site and I don't know of or atleast have heard of anyone on this site get that high. I don't get why you guys are all jumping on me for being a bit skeptical about the mpg with a manual, when I can recall that some of you on this site were telling me that when I told you that this lady I e-mailed got 76 mpg on her Automatic Insight, that I was lying or that was immpossible, or it was herrsay. I believe that the lady I e-mailed got 76 mpg on her Insight with a automatic. In fact here is the e-mail that I sent her:
Hi Chris -- glad you're interested in the Insight. It's a fun
little car -- I particularly like zooming around curves while cars
without sport suspensions lumber along behind me.
How fast does the Insight go?
The top speed is supposed to be 112 mph. I've only been up to
about 85, but the car doesn't seem to be working too hard at that
speed.
What is the highest mpg that you have gotten on the Insight?
I got 76 mpg on the way to work once. My commute is about 30 miles
mostly on the interstate, so I can get pretty high numbers. I have
an automatic transmission -- the manuals get better mileage.
People with manuals often have a lifetime mpg in the range of 76,
whereas mine is 56. It's better in warm weather.
How does the Insight handle?
Wonderfully! As I mentioned, it's low to the ground with a sports
car suspension. People who like to drive love to take my car for
spin. Of course, your mileage suffers when you're zooming and
accelerating (you might get 50 mpg instead of 60), but it's so much
fun that I just can't resist from time to time.
How is the ride, is it a smooth ride?
No -- it's bumpy. The suspension is tight, and the low rolling
resistance tires which bump up your mileage are small and hard. I
don't notice, but if you're used to a cushy ride, you might.
Do you get alot of attention with your Insight?
Not as much as you'd think! I hear they get more attention
elsewhere in the country. I live on the east coast, and I've only
been stopped in parking lots a couple times. I occasionally get
grins and thumbs up from other drivers, especially since I added
the "My car sips gas, your car sucks" bumper sticker.
How often do you have to refuel your Insight?
Every two weeks. I commute about 60 miles round trip to work and
school 4 days a week. If you're driving to suit the car, you can
get 600 miles out of a tank. If you're driving to have fun, you
get 500. My gas light comes on when I have 1.3 gallons left, so you learn
not to rush to the pump right away -- why fill up when you have 80
miles left? It's more fun to push it a little and see if you can
get a new tank record. I reset one of the trip odometers with each
tank, so I can calculate from the tank mpg and odometer reading how
far I'm going to get.
Is the Insight fun to drive?
Oh yes! I think I covered that

You've probably heard that the
pick-up isn't great. I haven't found it to be a problem -- I can
blow away from stop lights when I feel like jibing the person next
to me, and merging and passing are not a problem. When you
accelerate, the electric engine supplements the gas engine, and
it's my understanding that electric engines have more torque so you
get better acceleration. The automatics also have a "second gear"
button on the steering wheel that you can push when you need to
throw mileage to the wind and really accelerate.
Is the digital speedometer hard to see during the day?
Only if the sun is really glaring on it. In normal light it's very
bright, even if you've turned the headlights on to go through a
tunnel (which dims the dash lights) and forgotten to turn them off.
http://insightcentral.net is a source of all sorts of fascinating
things about Insights, and there are some Yahoo groups that are
good to ask questions on it. I'm on the honda-hybrid group for
Insights and Civics, and while most of the discussions aren't of
interest to me, they do come out with the occasional tidbit and are
generally happy to tell people about hybrids.
I'm casting a somewhat covetous eye toward the 2004 Prius --
the keyless buttonless entry and start intrigues me, and all Priuses
run in fully electric mode up to about 20 mph, so they're great for
inching in slow traffic. But, try as they might, they just don't
look like my spaceship.
