Electrics are considered superior due to the silent electric motors. They also offer long range and high specific energy. The introduction of the semi-conductor controls and improves batteries and can deliver a high torque at low revolutions, simply convenient isn’t it.
Today, automotive fuels also include ethanol and alcohol fuels and bio-gasoline. Alcohols are blended with gasoline in these automobiles or cars due to the less energy per liter exhibited by them. Alcohols are used to increase octane, reduce emissions, and as alternate fuels that can be got from crops. This certainly keeps a check on the green house effects and such automobiles are the need of the hour.
Gasoline engines have the advantage of being lighter than diesel and they can work at higher rotational speeds. The consistent development of gasoline engines has improved efficiency and reduced pollution. Indirect fuel injection used in aircraft engines is now a part of racing car engines and road cars running on gasoline. The Clean Air legislation has made it mandatory for automobiles or cars running on gasoline to be fitted with catalysts and fuel injection. Gasoline engine automobiles or cars can also run on LPG, with modifications. This does affect the mileage but it still is considered convenient and useful by many.
