Hybrid Systems: Hybrid & Electric Powertrains for Cars, Trains & Ships
Hybrid systems combine more than one power source, such as an engine with electric motors, to improve efficiency and cut emissions. These guides cover hybrid and fuel cell cars, hydraulic hybrids, and hybrid electrical systems in trains, ships and off-road vehicles.
Road vehicles
Hybrid, hydraulic and fuel cell vehicles.
Trains, ships & off-road
Hybrid electrical systems beyond passenger cars.
Sustainability
Why hybrid and electrified systems matter.
Frequently asked questions
What is a hybrid electric vehicle?
A hybrid electric vehicle is driven by both an internal combustion engine and one or more electric motors that use energy stored in a battery. It is not plugged in to charge.
What is a hybrid hydraulic vehicle?
A hybrid hydraulic vehicle is a non-electric hybrid alternative that stores energy hydraulically instead of in a battery.
How do hybrid trains work?
Hybrid trains use hybrid electrical systems in their design to improve efficiency and reduce emissions compared with conventional locomotives.
How does a fuel cell vehicle differ from a battery electric vehicle?
A fuel cell electric vehicle generates electricity with a hydrogen-powered fuel cell to drive an electric motor, instead of relying on a battery as its main power source.
