Hybrid Cars Hybrid cars are the transportation of the future. Humans have been driving around since the 1880’s. They started off as simple‚ one-cylinder machines‚ to today‚ where they are twelve cylinder animals. From fuel-efficient coupes‚ to gas guzzling SUVs‚ or even the ultra expensive supercars‚ all use gasoline. The use of this gasoline makes or breaks the selling point of the car. We base the cars off of their utility; the gas-guzzlers may be the ones with the most torque and pulling

and reduces brake wear. Hybrid electric vehicles Hybrid electric vehicles (HEVs) are powered by a combination of electricity and either petrol or diesel. The electricity is used only as an intermediate energy storage medium to improve the overall efficiency of the vehicle. They therefore DO NOT need to be plugged in to recharge the battery. This cuts down on the amount of fuel needed‚ producing fewer emissions and lowering overall fuel costs. As with BEVs‚ most hybrids also use ‘regenerative braking’
