Quite simply, a hybrid combines at least one electric motor with a gasoline engine to move the car, and its system recaptures energy via regenerative braking. Sometimes the electric motor does all the work, sometimes it's the gas engine, and sometimes they work together. The result is less gasoline burned and, therefore, better fuel economy. Adding electric power can even boost performance in certain instances. With all of them, electricity comes from a high-voltage battery pack separate from the car's conventional volt battery that's replenished by capturing energy from deceleration that's typically lost to heat generated by the brakes in conventional cars.
This happens through the regenerative braking system. Hybrids also use the gas engine to charge and maintain the battery. Car companies use different hybrid designs to accomplish different missions, ranging from maximum fuel savings to keeping the vehicle's cost as low as possible.
In this most common design, the electric motor s and gasoline engine are connected in a common transmission that blends the two power sources. That transmission can be an automatic, a manual, or a continuously variable transmission CVT. Transmission type and the size of the gasoline engine are the main factors that determine how a parallel hybrid will accelerate, sound, and feel.
In this design, the electric motor s provides all the thrust, and there is never a physical mechanical connection between the engine and the wheels. The gasoline engine is just there to recharge the battery. This results in a driving experience that's more indicative of an electric car, with smoother, powerful acceleration. Most strong hybrids will have a choice of power modes, too, ranging from eco to power, enabling the driver to choose maximum efficiency or performance depending on the driving conditions.
However, if you do a lot of motorway miles you may be better off with an efficient diesel car. For all the latest reviews, advice and new car deals, sign up to the What Car?

Everyone from Toyota to Porsche sells hybrid cars these days, but which models should you consider and which should you avoid? The Seat Leon, our favourite family hatchback, is now available as a plug-in hybrid. We're living with one to find out if it's the pick of the range. Does that make it a match for its Volvo XC60 rival? What Car? View all new car reviews. How do hybrid cars work? Parallel hybrid cars. Car deals. View all deals. Range extender hybrid cars These only use their conventional engine to produce electricity for a generator that recharges the batteries.
Plug-in hybrids As the name implies, this type of hybrid can be plugged into an electric outlet to recharge their batteries, as well as being charged on the move.
Key Components of a Hybrid Electric Car Battery auxiliary : In an electric drive vehicle, the low-voltage auxiliary battery provides electricity to start the car before the traction battery is engaged; it also powers vehicle accessories.
Electric generator: Generates electricity from the rotating wheels while braking, transferring that energy back to the traction battery pack. Some vehicles use motor generators that perform both the drive and regeneration functions. Electric traction motor: Using power from the traction battery pack, this motor drives the vehicle's wheels. Exhaust system: The exhaust system channels the exhaust gases from the engine out through the tailpipe.
A three-way catalyst is designed to reduce engine-out emissions within the exhaust system.
