This might be a good guide for new hybrid buyers.
For years, some people have avoided cars with expensive stereos because it's assumed it's a 20-something guy that races the car a lot. The lifetime MPG display would seem to be a far more accurate indicator of potential abuse, although not completely foolproof (it can be reset).
For a 5-speed Insight, I would not touch one with a lifetime MPG under 45, probably even 50. Assuming it was in good working order, 50mpg is almost certainly agressive driving, severe stop-and-go, very short trips, or freezing weather. I have to work to get it down to 45mpg if I'm not gridlocked in traffic. The few times I hear 5-speed Insights with lifetime MPG under 45, I can't help but to believe it's a lemon or been victim of very abusive driving.
In addition to the typical acceleratoin of tire and suspension wear, abusive driving on hybrids will shorten the battery pack. I'd suspect the O2 sensor as well.
So hybrid drivers, what do you consider the "abuse zone" on:
- 5-speed Insight - 45, maybe 50
- CVT Insight
- pre 2006 Civic
- 2006 Civic
- Accord
- Prius I
- Prius II
- Ford Escape
- Toyota Highlander
- Lexus rx400
- other hybrids
