- There are added registration fees in some states.
- They cost more - anywhere from $2,000 to $5,000 more the non-Hybrid version of the same vehicle.
- Hybrids have a more complex powertrain, which means more chances for failure and fewer fixes that your typical mechanic could do.
- Parts may cost a bit more and not be as readily available as typical car parts.
- Special high-mileage tires are smaller, but they cost more to replace.
- The acceleration capability of some (not all) Hybrids is less than that of comparable vehicles.
- High-performance electric motors are not yet available in Hybrid vehicles, whose emphasis is on economy not speed. (However, they're getting better each year.)
