Hybrid cars are complex vehicles that have a simple purpose: to reduce the amount of fuel emissions released into the air. Since a hybrid car combines an engine that uses gas with a motor that reduces gas consumption, these two things balance each other out to increase gas mileage.
Hybrid cars are indeed very efficient yet expensive, but looking at the less fuel cost it's indeed a bang for the buck. The downside of hybrid is it produces less power that's mainly why most hybrid prototypes lacks corners and edges because eliminating the drag is one way to compensate the downgrade to power in hybrids. They are not all fuel-sippers, although some have high performance and high prices.
These types of cars are economical and can get up to 55 to 60 mpg in city driving, while a typical SUV might travel 15-20 miles per gallon, or use three times as much gas for the same distance! They are better than all-electric cars because hybrid car batteries recharge as you drive so there is no need to plug in and most electric cars cannot go faster than 50-60 mph and are the beginning of the end for gasoline cars. These cars are built with much smaller, more efficient engines than regular cars. Most of the time, you don't need the extra power afforded by the larger engine, anyway.
Hybrid cars are starting to become more popular in America, but they are still new to the car market. In the years to come even more hybrids will become available. They are starting points, not as efficient as we'd like, but they will lead to future technologies like cellulose and prairie grass, and other as yet created technologies. They are a growing market due to the obvious environmental benefits and fuel efficiency and the market is expected to continue to grow well into the future.
Diesel and Hybrid Cars
Diesel cars are less common in North America, but can still be found in use in parts of Europe. In North America diesel tends to be used in trucks rather than cars, and the cars run on gas instead. Diesel engines are present in some hybrid models, which are more energy efficient than gasoline engines. There is speculation that some companies have developed a hybrid model that runs on hydrogen fuel. These hybrid diesel cars get better bas mileage, but availability of these cars is currently limited to certain states. New technology for diesel engines redefines them as clean, low-polluting and still high-mileage.
Hybrid cars are cars that use both an electrical source and an internal combustion engine to propel the vehicle. They are as safe as any other vehicle in their class. They are given the same crash tests and scored the same. Hybrid cars are a step in the right direction but in small numbers will not have a significant impact on air pollution.
