Potential future car technologies include varied energy sources and materials, which are being developed in order to make automobiles more more energy efficient with and reduced regulated emissions. Cars are being developed in many different ways.
With rising gas prices, now the future of cars is leaning towards fuel efficiency, and energy-savers, hybrid vehicles, battery electric vehicles and fuel-cell vehicles.

Energy sources
Main article: Alternative fuel vehicle
One major problem in developing cleaner, energy efficient automobiles is the source of power to drive the engine. A variety of alternative fuel vehicles have been proposed or sold, including electric cars, hydrogen cars, compressed-air cars and liquid nitrogen cars.
In one experiment done to improve the future of cars, an old kind of battery was installed which can not be removed, and recharged in two different ways. First, by a generator integrated with the IC and second by removing the cassettes so that they can be recharged off-board in the home ( Charters, Watkinson, Wykes, & Simpkin, 2008).
Energy saver
Conventional automobiles operate at about 15% efficiency. The rest of the energy is lost to engine and drive-train inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous.
Various technologies have been developed and utilized to increase the energy efficiency of conventional cars or supplement them, resulting in energy savings.
Regenerative braking technology saves and stores energy for future use or as back up power. When conventional brakes are used, 100% of the kinetic energy lost is converted to thermal energy, and dissipated in the form of heat. Regenerative braking recovers some of this energy to recharge the batteries in a hybrid vehicle.
BMW's Turbosteamer concept uses energy from the exhaust gases of the traditional Internal Combustion Engine (ICE) to power a steam engine which also contributes power to the automobile (Hanlon, 2005). This can increase energy efficiency by up to 15%.
Compressed air Hybrid is an engine made by researchers at Brunel University in Britain, which forces highly compressed air into the engine, which they claim reduces fuel consumption by 30%.
Utilization of waste heat from D.W. as useful mechanical energy through exhaust powered steam, stirling engines, thermal diodes, etc.
Using computational fluid dynamics in the design stage can produce vehicles which take significantly less energy to push through the air, a major consideration at highway speeds. The Volkswagen 1-litre car and Aptera 2 Series are examples of ultra-low-drag vehicles.
Materials
Duraluminum, fiberglass, carbon fiber, and carbon nanotubes may totally replace all steel in cars (potentially improving lightness and strength). Aluminum, carbon fiber and fiberglass are currently being used more in cars today.
Plastic and foam for the car's shell; foam can provide additional safety for pedestrians, ... and can also make the car buoyant.
