One negative impact is the false belief that these autos are doing something good for the environment. Some models are more cost effective and use less gas then conventional autos and these can create a slight improvement over conventional systems. The pollution created by creating these other systems though is ignored.

A small car getting 50 mpg with a conventional engine is far better, from an environmental impact, then a hybrid getting 55 mpg. Larger hybrids fair even worse.

The braking problem that is now associated with Toyota's hybrids should not be ignored either.

The greatest issue though is the increased expensive of ownership and the technology inside these automobiles. The projected lifespan is shorter for these cars (and thus the increased issue of disposal) has not really been factored into their life cycle.

Some reports falsely accuse these cars of being a greater source of pollution then a Hummer. The truth is somewhere in between. If you want a peppy little in town run about the Prius is a nice choice. Just do not buy it to help the environment. They are probably about a neutral over a conventional Aveo.

How long do the engines in hybrid cars usually last?

If properly maintained, hybrid engines can last 10-20 years or even longer. The battery will need to be replaced, however. With a hybrid car, the concern is generally with the lifespan of the battery since that is where the car gets its power and that is what distinguishes it from a regular engine. The batteries on a hybrid vehicle are intended to last for the lifetime of the car. The engine should also last for the car's lifetime if it is properly maintained.
