Hybrid Car Efficiency
For the first, the gas engines that the hybrid cars feature are very efficient in themselves, and offer fuel efficient usage. However, the real kicker that extends the fuel efficiency much more is the electric motor. The electric motor, which typically uses no gas (unless the electric motor needs to recharge by using the engine as a last resort). Typically, the electric motor batteries are recharged automatically while you drive. This recharging may come from a process called regenerative braking, which means the electric motor acts as a generator and charges the batteries while the car is slowing down during braking. Also, hybrids may use periodic engine shut off, which is when a hybrid car is stopped in traffic, the engine will temporarily shut off, then restarting automatically as put back into gear. Hybrids also use advanced aerodynamics, which will reduce drag and increase fuel efficiency. Many hybrid cars are also manufactured to use low-rolling resistance (LLR) tires that are narrow, stiff tires that have less drag, again, increasing fuel efficiency. Finally, many hybrid cars use lightweight materials, and as the car is lighter in weight, the engine will have to work less, increasing fuel efficiency.
