BMW hybrid car or BMW hydrogen powered car

Image hosted by

Is BMW coming with BMW hybrid car. No, BMW is not coming with BMW hybrid car but hydrogen powered cars and fuel cell cars. BMW German carmaker's H2R is the world's fastest hydrogen powered car that has speed upto 185 miles per hour.

Generally, hydrogen-powered vehicles operate on fuel cells. In BMW Hydrogen, powered car uses a modified 6-liter, 12 cylinder combustion engine for its propulsion. Engine in BMW emits only water thus making is one of the most environment friendly car in the present times.

BMW hydrogen powered car has higher degree of efficiency due to higher combustion pressure of the hydrogen-air mixture. Though hydrogen powered BMW hybrid car would give a no exhaust car but the sources through which the hydrogen come is very damaging to environment. The sources might be either fossil fuel like natural gas or by the use of grid electricity both of which releases hydrocarbons while production.

BMW is also developing fuel cell cars. It is developing combustion engine as the sum total of features and characteristics offered by it has got largest number of advantages all in one.

Electric and hybrid cars, Difference between electric and hybrid cars

Electric cars, hybrid cars: Difference between electric and hybrid cars. Why hybrid car is better then all electric cars.

Batteries: Hybrid car batteries recharge while you are driving. There is no need for plug in where, as after certain miles, electric vehicle batteries need recharge. Most electric cars need a recharge every 50-100 miles.
Speed: Electric cars could go only up to 50-60 miles/hr where as hybrid cars can go much faster then that.
Size: For maximum efficiency electric cars are small whereas we have SUVs in hybrid cars.
Price: Electric cars are cheaper then hybrid cars

Since long, people have been working hard to improve the batteries for electric cars. Still electric cars can only travel a fraction of distance traveled by gasoline cars. Hybrid car is the result of efforts put by people in developing electric cars and having faith in cars powered by electric motors. Hybrid car development is only a change in tactics due to failure in improvement of efficient batteries. Hybrid cars could be defined as an electric car assisted with a gasoline engine.
