Hybrid Cars: Explained
March 18, 2018
When considering cars and efficiency, and researching hybrids, the information can often be dizzying.
Hybrids utilize both gas and electricity. It is in this that a vehicle can be either more or less efficient. Here is, in part, an explanation.
The driver of a hybrid eases out of the driveway, and on to a neighborhood street going at a very low speed. Electric motors do very well at low speed. Once on a highway traveling at a higher speed gas is more efficient.
With this combination of energy you can expect to get over 45 miles per gallon, which translates into savings that would not be awarded if the vehicle is using only gas.
For the sake of discussion we will talk about the Atkinson engine. The power is less than a standard, but less gas will be used so the savings will go into your wallet.
Over time designs have evolved so even when breaking the hybrids use the energy to recharge batteries.
The design of the transmission does not involve gears, but by a pulley system which gives the greatest RPM.
Tires are often more narrow which translates into less resistance. When some tires are kept at a higher pressure than a normal tire there is less resistance, so better mileage is awarded.
No gas is wasted when the vehicle is at a stand still, because the gas powered motor does not idle, but turns off.
Unlike regular power steering which is operated by belts, electric power steering can be operated even when the vehicle off.
The AC is also electric, so can also be used while engine is off. |
Most who are interested in hybrids because of their efficiency? Some offer an economy option. This mode of operation will lessen acceleration, but will offer better mileage.
