Introduction
The distinction between hybrid cars and plug-in hybrids is often overlooked by many. Both types utilize a dual-engine system, combining an internal combustion engine with an electric motor. The vehicle alternates between these two power sources depending on the driving conditions. However, despite their similar names, there are significant differences that may make one option more suitable than the other.
Hybrid Cars
Most of us know that the primary fuel source for hybrid cars is gasoline. However, during low-speed driving, these vehicles rely on their electric motor for propulsion. When more power is needed, the vehicle automatically switches to its internal combustion engine. In scenarios demanding greater power, both systems work in harmony to provide the necessary performance.
Plug-In Hybrid Electric Vehicles
The best way to describe plug-in hybrid vehicles is as "electric cars" that are supplemented by an internal combustion engine. The electric motor is the primary source of propulsion, and when the battery charge is low, the vehicle automatically shifts to the internal combustion engine. This allows the electric motor to recharge until its battery is sufficiently charged. In these cars, the electric motor is the main driver of power, while the internal combustion engine acts as a supportive source.
Which is More Efficient?
When it comes to fuel efficiency, plug-in hybrids often outperform traditional hybrid cars. For instance, comparing two models: Toyota Prius (hybrid) and Chevrolet Volt (plug-in hybrid), the Toyota Prius needs to travel over 390 km to match the fuel efficiency of the Chevrolet Volt.
