HYBRID CARS

Modern mass-produced hybrids such as the Toyota Prius and Honda Insight recharge their batteries while in use. While cruising or idling, some of the output of the combustion engine is fed to a generator. Nearly all hybrids still require gasoline as their main fuel source - though diesel and other fuels such as ethanol or plant based oils have seen increased use. One benefit of hybrids is reduced wear and tear on the gas engine. Another is their ability to capture kinetic energy.
Next years model of the Prius is expected to achieve about 100 MPG with the use of litium batteries.
