Regenerative breaking system
In conventional gasoline-powered cars, all the kinetic energy (energy in motion) is lost and wasted during braking. Hybrid cars
Low-rolling resistance tires
Tires are often not seen as a major factor in increasing the fuel economy. But in hybrid cars
Fuel economy
Not all hybrids are fuel efficient. Some are made to perform. And even if the hybrids are made to get the longest miles out of every gallon of gas, some are still better than others. For example, the Ford Escape Hybrid runs 34 mpg in the city and 30 mpg on highway. Toyota Prius runs 48 mpg in the city and 45 mpg on highway. The Honda Civic Hybrid runs 40 mpg in the city and 45 mpg on highway. When choosing what hybrid car to buy, take note of these differences.
Periodic engine shut off. Idling consumes fuel too. So, most hybrid cars
Smaller and more efficient engine
Logically, the car does not actually need a V6 or a V8 in order to run because most of the time, your car only requires 20 hp to move. The extra horsepower is only needed during acceleration. This is the reason why hybrid cars
Safety, Comfort, and Space
These are 3 issues that are questionable to hybrid cars
