What Makes a Hybrid Car a Hybrid?
The Honda Insight and Toyota Prius were pioneers in the hybrid car market back in the 1990s, and since then, hybrid powertrains have gained significant popularity among car buyers. These buyers see hybrids as a bridge between traditional internal combustion engine (ICE) vehicles and fully electric cars. This surge in interest has led to a remarkable increase in hybrid and electric car sales in the United States, with hybrids and plug-in hybrids outselling pure electric vehicles. Experts predict that hybrids will account for over 20% of total vehicle sales by 2024.
So, what exactly defines a hybrid car? Simply put, a hybrid car combines an internal combustion engine, usually powered by gasoline, with an electric motor to provide power to the vehicle. The electric motor and engine work together to move the car, with the electric motor typically being smaller than those found in fully electric vehicles. The battery pack that supplies electricity to the motor is also smaller in hybrid cars. The combustion engine in a hybrid is designed for efficiency rather than power since it works in tandem with the electric motor to propel the vehicle.
Why Do We Have Hybrid Cars?
While electric cars offer numerous benefits, they can be expensive and challenging to produce. Additionally, some owners may face challenges related to range anxiety and charging infrastructure availability. Hybrid cars bridge this gap by combining the convenience of refueling with the efficiency of an electric motor and battery. They allow drivers to enjoy better fuel economy, reduced emissions, and a normal driving range without the limitations of pure electric vehicles.
Understanding Different Types of Hybrid Cars
Hybrid cars are more complex to design and produce compared to traditional ICE vehicles or pure electric vehicles. They essentially blend two different types of powertrains into a single driving experience. There are four types of hybrid cars: mild hybrids, parallel hybrids, series hybrids, and plug-in hybrids. Mild hybrids have a small electric motor that provides a slight boost when accelerating from a stop, resulting in a marginal gain in fuel economy. On the other hand, parallel hybrids, like the Toyota Prius, have both an ICE engine and an electric motor that can work together or independently to provide power.
Series hybrids, such as the original Chevrolet Volt, function like electric cars with an onboard generator. They use the ICE engine to charge the battery pack, which then powers the electric motor that drives the wheels. Some hybrid cars, like the Honda Accord Hybrid, can operate in both parallel and series modes. The engine can power the front wheels in certain situations, but for the most part, the car relies on its powerful electric motor while the engine replenishes the battery.
Plug-in hybrids, regardless of whether they are parallel or series hybrids, have the ability to be charged externally. They can be plugged into a power source to charge the onboard battery, offering extended electric-only driving range compared to conventional hybrids. This makes plug-in hybrids similar to electric cars in many ways. Today, hybrid options are available for various types of vehicles, including hatchbacks, SUVs, pickup trucks, and even off-roaders.
What Isn’t a Hybrid Car?
Cars powered solely by internal combustion engines (ICE) are not considered hybrids. These are the standard vehicles that have been dominating the market for years. From compact cars to pickup trucks, most vehicles sold today rely solely on gasoline, diesel, natural gas, or other combustion engines. They do not have any electric drive power, which sets them apart from hybrids.
Another type of vehicle that is not a hybrid is the electric car. As concerns about emissions and the environment have grown, car manufacturers have started developing electric vehicles to reduce carbon emissions. Electric cars eliminate the need for a combustion engine and instead rely on an electric motor, a battery pack, and advanced electronics to run solely on electricity.
In conclusion, hybrid cars have become increasingly popular due to their ability to combine the best features of traditional ICE vehicles and electric cars. They offer improved fuel economy, reduced emissions, and a normal driving range. With various types of hybrids available, there is a hybrid option to suit different needs and preferences. As technology advances, the hybrid market is expected to continue growing, providing consumers with more efficient and environmentally friendly transportation options.
