What Is A Hybrid Car?

By PattyKay Lilley

The development of the hybrid car marks a groundbreaking advancement in both the automotive and technology industries. Not only does this revolutionary vehicle offer improved fuel efficiency, but it also comes with added environmental benefits that make it increasingly attractive to drivers everywhere.

But what exactly is a hybrid car? In this blog post, we’ll attempt to answer this question by exploring its core components, history of development, and unique advantages that no other vehicle on the road can offer.

What Is A Hybrid Car?

A hybrid car is an automobile that utilizes more than one means of power to propel itself. Typically, a hybrid car combines a conventional internal combustion engine with an electric propulsion system. This dual power system is where the term ‘hybrid’ comes from.

The primary goal of hybrid technology in vehicles is to enhance efficiency and reduce emissions. The combustion engine is designed to kick in when the car needs additional power for acceleration or climbing hills, while the electric motor handles lower-speed driving, thereby reducing the vehicle’s reliance on gasoline.

The history of hybrid cars can be traced back to the late 19th century, but it was not until the late 20th century that the technology started to become more refined and commercially viable. One of the first successful mass-produced hybrid cars was the Toyota Prius, launched in Japan in 1997 and internationally in 2000.

Hybrid cars offer numerous advantages, the most notable being superior fuel efficiency. By using an electric motor for low-speed driving, hybrids can achieve significantly better fuel economy than conventional cars.

Moreover, they produce fewer emissions, making them a more environmentally friendly choice. Some hybrids also qualify for tax credits and other incentives, making them an economically attractive option as well.

However, it’s important to note that hybrid cars are not a one-size-fits-all solution. They are best suited for drivers who do a lot of city driving, where the stop-and-go traffic allows the electric motor to be used more effectively. For those who do most of their driving on highways, a diesel or gasoline car might still be a more efficient choice.

Type of Hybrid Vehicles

Type of Hybrid Vehicles

There are several different types of hybrid vehicles, each with its unique configuration and driving characteristics.

Parallel Hybrid

In the most common design of hybrid vehicles, which combines an electric motor(s) and a gasoline engine, they are connected through a common transmission. This transmission, which can be an automatic, a manual, or a continuously variable transmission (CVT), effectively blends the power from both sources. One particularly popular hybrid transmission is a power-split CVT, which is utilized by industry pioneers like the Toyota Prius and Chevrolet Volt.

When it comes to parallel hybrids, the type of transmission and the size of the gasoline engine play a pivotal role in determining the acceleration, sound, and overall driving experience. Some notable brands that employ the parallel hybrid design include Toyota, Lexus, Hyundai, Kia, Ford, Honda, Lincoln, Nissan, and Infiniti.

This design not only offers improved fuel efficiency and reduced emissions but also provides a seamless and enjoyable driving experience that combines the benefits of electric power and internal combustion engines.

Series Hybrid

In the series hybrid design, the electric motor(s) exclusively generate thrust, with no direct mechanical connection between the engine and the wheels. The primary purpose of the gasoline engine is to recharge the battery, acting as an auxiliary power source.

This innovative configuration ensures efficient performance and seamless integration between the different components, resulting in a highly optimized and environmentally-friendly driving experience.

This results in a driving experience that closely mirrors that of an electric car, characterized by smoother, powerful acceleration. Typically, engagement of the gasoline engine results in less vibration.

However, this engagement doesn’t always align with what your right foot is doing – the battery’s demands dictate the engine’s operation. As such, the engine might be revving up while the car is cruising at a steady speed, which some drivers might find disconcerting.

An excellent example of a series hybrid is the BMW i3 with the range extender, which perfectly embodies this unique hybrid configuration.

Plug-In Hybrid

A plug-in hybrid enhances the conventional hybrid concept with a much larger battery pack that, like an electric car’s, must be fully recharged using an external electricity source—from your home, office, or public charging station.

This greater amount of energy storage is like a larger gas tank: It allows for extended all-electric driving (between 15 and 55 miles depending on the model) and can significantly reduce fuel consumption. In fact, if you have a short commute and recharge nightly, you’ll be running on electricity most of the time.

Should you deplete the all-electric range, the car basically reverts to being a conventional parallel hybrid. The Chrysler Pacifica plug-in hybrid (shown above) is an example of the plug-in breed.

Mild Hybrids

Mild hybrids represent a more cost-effective version of hybrid technology. These vehicles incorporate a small electric motor that assists the internal combustion engine but doesn’t drive the vehicle on its own.

The electric motor serves to enhance the vehicle’s performance, enabling it to restart quickly and smoothly when the vehicle comes to a stop and the engine shuts off, such as in traffic situations.

In mild hybrids, the compact electric motor also assists with acceleration, reducing the workload of the gasoline engine and thereby improving fuel efficiency. However, in contrast to full hybrids, mild hybrids can’t drive on electric power alone. They’re best perceived as gasoline-powered cars with electric assist, rather than a balance of power sources.

The main advantage of mild hybrids comes in the form of lower cost compared to full hybrids, presenting a more affordable option for drivers wanting to reduce their environmental footprint without a significant upfront investment. An example of a mild hybrid is the Chevrolet Malibu Hybrid.


Hybrid vehicles, with their eco-friendly credentials and fuel efficiency, have become an increasingly popular choice among consumers. However, the technology and its various options can sometimes generate confusion, leading to several frequently asked questions.

What makes a hybrid car different from a regular car?

A hybrid car differs from a conventional vehicle in that it uses more than one form of onboard energy to achieve propulsion. Typically, this will involve a traditional internal combustion engine and an electric motor.

Hybrid cars capitalize on the strengths of these individual components to optimize fuel efficiency and reduce emissions. The electric motor, powered by a battery, provides efficient power for low-speed driving and assists the gasoline engine when accelerating or climbing hills.

The gasoline engine, on the other hand, is more efficient at steady, high-speed driving and can also recharge the battery.

How does a plug-in hybrid differ from a regular hybrid?

A plug-in hybrid enhances the hybrid design with a much larger battery pack that must be fully recharged using an external electrical source—home, office, or public charging station.

This larger energy storage allows for extended all-electric driving, which can significantly reduce fuel consumption. If the all-electric range is depleted, the car reverts to being a conventional hybrid, powered by both gasoline and electric power.

Are hybrid cars more expensive to maintain?

While hybrid cars might have a higher upfront cost, their maintenance cost does not significantly differ from that of conventional cars. In fact, hybrids can often be cheaper to maintain.

The brake system in a hybrid experiences less wear and tear thanks to regenerative braking, which uses the electric motor to assist in slowing the vehicle. Moreover, because the electric motor can handle a lot of the low-speed driving, the gasoline engine doesn’t have to work as hard, leading to less engine wear and tear as well.

Lastly, many hybrids come with extended warranties that cover the cost of repairs to the hybrid system.

Final Thoughts

Hybrid cars represent a significant step toward sustainable transportation, merging the best of internal combustion engine and electric motor technologies. They offer a compelling balance, delivering improved fuel efficiency, reduced emissions, and a seamless driving experience.

However, like any technology, hybrids are not without their trade-offs. They may have higher upfront costs compared to conventional vehicles, and their performance may differ from what some drivers are accustomed to. Yet, the long-term savings on fuel and maintenance, coupled with their environmental benefits, make them an increasingly attractive option.

As technology continues to progress, hybrids are becoming more efficient, affordable, and diverse in their offerings. The range of options—from mild hybrids to plug-in hybrids—means that consumers can select a vehicle that best fits their lifestyle and driving habits.

Ultimately, as we move toward a more sustainable future, hybrid technology demonstrates that we can evolve our transportation methods without compromising on performance or convenience. As consumers and automakers continue to embrace this technology, the road ahead looks promising for hybrid cars.
