Hybrids combine the best of EVs and gas cars. The General used Department of Energy data to identify the top 15 most fuel-efficient hybrids in the U.S.
Air resistance is the main cause expended energy per distance when driving at high steady speeds. [11] At higher speeds, wind resistance plays an increasing role in reducing fuel economy in automobiles. At 60km/h, the global average speed, energy loss due to air drag in fossil fuel cars is approximately 5% of the total energy loss.
The unit of energy consumed is deemed to be 33.7 kilowatt-hours without regard to the efficiency of conversion of heat energy into electrical energy, also measured in kilowatt-hours (kWh). The equivalence of this unit to energy in a gallon of gasoline is true if and only if the heat engine, generating equipment, and power delivery to the car ...
Because the process of manufacturing many low emission vehicles (LEV), for example, a hybrid engine, is more technology intensive, and therefore more expensive, than the process of manufacturing a standard gasoline engine, the up-front cost of a hybrid automobile is greater than that of a car with comparable performance.

Until recently, it felt like electric cars had earned exclusive rights to the future of the auto industry. But EVs went mainstream so quickly that everyday consumers got an intimate look at their...
In the worst-case scenario, the study estimated that for a region where all energy is generated from coal, a plug-in electric car would emit greenhouse gas emissions equivalent to a gasoline car rated at a combined city/highway driving fuel economy of 30 mpg ‑US (7.8 L/100 km; 36 mpg ‑imp).
Automotive superlatives include attributes such as the smallest, largest, fastest, lightest, best-selling, and so on.. This list (except for the firsts section) is limited to automobiles built after World War II, and lists superlatives for earlier vehicles separately.
A green vehicle, clean vehicle, eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels.
