Myth #3: All hybrid cars are fuel-efficient and have low emissions.

It's true that all hybrid cars are more fuel-efficient and emit fewer noxious gasses than their gasoline-only counterparts. But manufacturers of hybrid vehicles are concerned with both performance and environmentalism. It's just not possible to make a full-sized truck that gets fifty miles to the gallon, even if it does sometimes run off of recaptured energy and the electric motor.

Driving styles also affect gas mileage, and even consumers driving the most energy-efficient hybrids may be disappointed in their fuel economy. The difference made by hybrid engines is most noticeable to people who do most of their driving around town, and who follow energy conservation guidelines such as keeping their trunks empty and staying under sixty miles per hour.

Myth #4: Hybrid cars cost more to maintain.

The cost of maintaining hybrid cars is no higher than for gasoline-only vehicles. There's less wear on the engine and brakes, so the cars are predicted to require less repair over the life of the vehicle. Hybrid cars still need oil changes and tire rotations, but they don't need them any more frequently than other cars.

People shopping for hybrids are sometimes concerned that because hybrid technology is new, they will only be able to get their hybrid cars serviced at an expensive dealership. Most of the components of a hybrid vehicle are the same as a gasoline-only car, so independent mechanics are able to do most of the work on hybrids. As these cars are becoming more popular, many mechanics are also seeking out classes on hybrid technology.

Myth #5: Hybrid cars contain expensive batteries that need to be replaced often.

It's true that the batteries in hybrid cars cost a lot to replace. If you've voided your warranty by neglecting your car, then a new battery pack will cost between $2000 and $4000. However, the batteries are designed to last the life of the car, and won't need to be replaced frequently.

Manufacturers of hybrid cars understand that consumers are wary about the battery technology, and are offering warranties that show their confidence. Warranties on the batteries for hybrid cars last up to ten years or 100,000 miles, so consumers shouldn't have to worry about replacing the batteries in their hybrid cars.
