Nope, they are just very small gas power cars.
Yes SmartCar sells electric cares that have great fuel economy. These cars are small, compact and run off of electricity instead of gas. They are a great evironmentally friendly car.
Smart cars run on petroleum.
Neither, Gas cars create pollution that penetrate the ozone layer and begin to create a hole in it. Electric cars run out of battery after 120 or so miles.
There are cars that run on diesel, CNG (Compressed Natural Gas), LPG (Liquefied Petroleum Gas) and electric power.
An electric car doesn't go very fast and are usually small, Gas powered cars have much more torque and speed. Some newer cars run on both so when they are going slow they run on electricity but when they are going fast they run on gas. These are not electric cars though as the fuel used is gas to create the electric power. To answer your question, gas cars are far better because they can go further then 20 miles and are legal on our roads. There are no legal electric cars commercially built.and do not exist.
No, some cars run on diesel or liquid propane and there are also electric cars. Some also run on biofuel made from corn or vegetable oil...
Hybrid cars that run on batteries and gas as well as electric cars are available now. As technology improves, it is expected that these cars could become the majority of vehicles.
The vast majority of passenger cars run on gasoline (petrol) or gasoline mixed with ethanol. Some run on diesel fuel (or biodiesel), which most large trucks and buses use. A small minority of cars are all-electric or hybrid electric. Some buses and trucks run on natural gas.
Hybrid cars are not the same as an electric car. Electric cars run on electric power exclusively, while hybrid cars use a combination of electric energy and another fuel to run.
Some of the most fuel efficient cars are the smart cars like 2013 Smart ForTwo, Honda Fit EV, and the Scion iQ. These cars are electric so the fuel they use is used to create the electricity they run on.
No, the hybrid cars do not use as much gas as a regular car. Electric cars use a number of batteries to store usable electricity to cut the need of gas to power cars by a significant fraction.
No, they dont run on gas, therefore exhaust is not giving off.
