I just got done adding this to another thread...
I've owned two hybrids, now. A Prius C and, now, a first generation Insight. Do not be discouraged by the winter mileage. The cold, dense air, the snow and frozen slop adding weight and ruining airflow, the change in fuel chemistry, and the slower batteries all conspire to ruin the mpg. I am a careful driver and still lose about 20% in the cold. I did on the Pruis and I do on the Insight. If you've not driven the car in warmer weather I bet you'll find it a completely different, and better car.
Unless you're into modifying your car (and I'm not) about 80% of the hypermiler stuff is gentle starts and stops, getting in the flow of the traffic, and letting the car do the rest. I use my cruise all the time and always keep up with the other cars and I get excellent mileage. You do *not* have to tailgate to increase the mileage. You know that big blast of air that follows traffic? All you have to do is be somewhere in there.
It's heartening to see a community starting to build around the latest incarnation of the Insight. Keep up the good work!
"LittleCar" : OH via NJ via VA : 3rd Owner : Silverstone 2002 MT : Nearing 150k miles
: No leaks : No Grind : No Mods (well.. ok... added cruise, window tint, new speakers, and clutch switch)
: New Battery (mfg ?) @ 125k + 2 years of sitting : 64.8 lifetime (resets ?)
I'd own a Karmann Ghia, but prefer to not freeze in the winter!
