You probably already know that a hybrid is a vehicle that’s a cross between an electric car and a gasoline-powered car. In the past few years, car engineers have wizened up to the fact that most of the time, you don’t need a lot of horsepower to keep your car moving.
If you’re the average driver, you rarely put the pedal to the medal. Even so, the gas engine in a gas-powered car has to be large enough to meet the power requirements of flooring it. In hybrids, though, you have an electric motor and battery that power your transmission. In some models, the transmission is hooked up to an electric motor and a gas motor in parallel. In others, the gas engine powers a generator, which powers the electric motor that runs the transmission. Either way, the electric motor gives your car extra power when it needs it.
Hybrids enable you to replace a big gas engine, with a smaller, more efficient one. And a smaller engine means the components require less energy to operate, and since it isn’t as heavy, you don’t need extra energy when you accelerate or drive up a hill.
And all that translates to lower gasoline consumptions and better emissions.
