some facts about hybrid vehicles



The picture is of some coral bells that bloomed last month.

We drive Toyota hybrids, a Prius and a Highlander. They do get better mileage than most cars of their size and weight. The Prius regularly gets between 40 and 50 miles per gallon. The hybrid highlander usually gives me between 25 and 30 mpg.

But there are some things that affect the mileage.
1. Wind can either boost or drop the efficiency.
2. Wet pavement makes the mileage drop.
3. Hilly terrain in the city lowers mileage, but at highway speeds can increase it.
4. Mountains: for some reason, we get up to 60 mpg when driving through the mountains.
5. Speed: the faster you go over 60 mph, the lower the gas mileage.
6. Traffic: stop and go traffic can raise the efficiency.
7. Air conditioning will drop between 2 and 8 miles per gallon on both cars. This one is a "Catch 22". If you drive at highway speeds with the AC off and the windows open, your mileage is worse than with the windows closed and the AC on.

All in all, we are pretty happy with the cars. They do save us quite a bit of gasoline. And all the gages and dials are fun to watch.
