Capitalizing on the strengths and efficiencies of two powerplants, hybrid cars have emerged as an important vehicle class. Hybrid cars generally operate with an internal combustion engine and electric motor working together in order to gain greater fuel economy or to boost power. Electric power for hybrid cars is sourced from power outlets or through regenerative braking. With many hybrid vehicles on the market in 2014, customers considering one are faced with many variations of the system. With so-called mild or micro hybrids, vehicles are equipped with stop/start system that automatically turns the gasoline engine off to save fuel. Mild hybrid cars can also provide limited assistance to an internal combustion engine. Micro or mild hybrid attributes include the Buick LaCrosse eAssist and the Mazda6 i-ELOOP model are more attractive financially and runs near seamlessly. If searching for greater fuel savings, parallel hybrid vehicles use a larger electric motor than mild hybrid cars. Parallel hybrid vehicles like the Toyota Prius can move on gasoline, electric or the combined power of both. Gaining popularity in the marketplace is range-extending or plug-in hybrid cars. Running like an electric vehicle for a distance, plug-in hybrid cars will begin using a fuel-burning engine when the vehicle’s battery is depleted. Plug-in hybrids work for drivers considering an electric car but are concerned with low battery ranges. The Chevrolet Volt as well as 2014 BMW i3 Range Extender models are examples of hybrids using a gasoline engine as backup power. If a driver only travels for a short range every day, it may be possible to rarely stop at a gas station. For the 2014 model year, the Toyota Prius and Ford Fusion are actually offered in a variety of hybrid configurations for buyers to choose from. Purchases of parallel type and plug-in hybrid cars will traditionally be supported by government tax credits.
