Here you will learn what Hydraulic Hybrid Vehicles are and what they are capable of!

The typical hybrid that everyone sees on the road today is a gas electric hybrid vehicle.  Commonly known as hybrid vehicles, these automobiles use an electric motor to create and store energy that turns the vehicles wheels.  Hydraulic Hybrid Vehicles are automobiles that use a hydraulic pump-motor to perform the same tasks.  Using this pump-motor, a reservoir, an accumulator, and in combination with an internal combustion engine, Hydraulic Hybrid Vehicles(HHVs) use this system turn the vehicle's wheels and ultimately, save energy, save money, and cut down on vehicle emissions. Energy is stored an accumulator or storage tank by using hydraulic fluid to compress a gas, usually nitrogen. During acceleration, the stored energy from the accumulator helps launch the vehicle. The big advantages to using a hydraulic hybrid is that they are far more efficient than standard gas vehicles and electric hybrid vehicles at capturing braking energy and they drastically cut down on emissions and fuel usage.  Major economic savings come in when it comes to fuel savings and brake maintenance.  Due to the lack of the use of the internal combustion engine, those engines also have a longer life than the engines in a typical vehicle powered by an internal combustion engine.
