Even though hybrid cars have been on the road for decades, they’re still a widely misunderstood technology by much of the driving public. Some Americans are simply too attached to their gas guzzlers to educate themselves about hybrids and how they work, leading to major misconceptions about these modern vehicles. But many myths are the fault of hybrid drivers and automakers, eager to push hyperbolic myths about the benefits of these cars.

Do you believe any of these common hybrid myths?

Claim: X Car gets 80 miles per gallon! The new X will get 200 MPG!

Every year you’ll hear new rumors and whispers of next-generation hybrid cars with a fuel economy that would turn Elon Musk green with envy. But don’t believe the hype. Hybrid cars might boast a higher fuel economy than your average car, but most of them have a fuel economy in the range of 30 to 40 mpg.

Claim: Batteries in hybrid cars die all the time! And the cost of batteries for hybrid cars negates and fuel economy savings!

Another false claim. In fact, electric batteries for cars can last for a whole decade. And even if they do break down, most come with an 8-year, 100,000 mile warranty to offset the cost of buying a hybrid battery replacement.

Claim: Hybrid batteries run out of charge constantly!

Actually, most hybrid batteries are designed in such a way to prevent them from going below a certain minimum charge level.

Misconception: Hybrids need to be plugged in.

While purely electric vehicles like Teslas need to be plugged in, most hybrids generate energy from the brakes. When you brake, a portion of the energy created is used to power the battery. In this way, hybrid batteries continuously charge themselves.

Of course, a lot of the things you’ve heard about hybrids are completely true. For example, they really do produce up to 30% less harmful emissions than normal automobiles. And with better fuel economy, they’ll save you money at the pump, too.
