Learn More About Future Hybrid Cars

Maintaining a vehicle is no longer as easy as it used to be. With rising fuel costs more and more car owners are finding it difficult to make ends meet. To meet the challenges posed by ever increasing fuel costs and pollution, car manufacturers are trying hard to come out with effective solutions. Hybrid cars – the new technology cars – offer drivers an efficient, innovative, and feasible option.

What are hybrid vehicles?

Any vehicle that combines two or more sources of power to exact propulsion power is a hybrid. Moped is a type of hybrid vehicle because it combines the power of a gasoline engine with the pedal power of its rider.

Most locomotives are diesel-electric hybrids. Diesel-electric buses which draw electric power from overhead wires and fall back on diesel when away from wires are also hybrid vehicles. Giant mining trucks are often diesel-electric hybrids.

Hybrid cars

A hybrid car is run by a small fuel-efficient gas engine coupled with an electric motor. The motor is powered by batteries that recharge automatically during a drive. Its function is to assist the engine when the engine is accelerating. The motor also helps to slow the car by a method called regenerative braking. In this mode, the electric motor acts as a generator and charges the batteries while the car is moving, slowing down or not running at all.

New hybrid cars are also equipped with unique features like periodic engine shut off. This feature enables the engine to shut off for a while when the car is held up in traffic, and restart automatically when you put it back into gear. Logically, the more electricity the car uses, the lesser fuel it consumes.

To help reduce the drag the cars also have latest aerodynamics features and low rolling resistance tires. Also, to enhance its efficiency it is built of lightweight materials. The lighter a vehicle is the less energy it needs to propel itself forward. New hybrid cars are designed in a way to fit snugly into modern lifestyle. To the viewing public they are attractive, stylish and uniquely fashionable.

Most hybrid cars today are based on gasoline-electric power drives. PSA Peugeot Citroen, the French car maker is working on a future hybrid car with a diesel-electric power combination.

Toyota Prius is, today, the best selling hybrid on the market. Hybrid cars of other companies include, Accord and Civic by Honda; GS 450h, LS 600H L, RX 400h SUV by Lexus; Aura Green Line and Vue Green Line by Saturn; Altima by Nissan; Camry, Prius and Highlander SUV by Toyota; Escape SUV by Ford and Mariner SUV by Mercury.

Our 21st Century Future: Alternative Energy

Some US trillion new global energy investments are needed in all stages of the energy supply chain to power the global community for the next two decades until year 2030. 

International analysts observe: the global energy demand is projected to shoot up by 55 percent, according to the International Energy Agency’s (IEA) most recent World Energy Outlook.

And more of IEA’s facts: that some 8.9 million appropriation is allocated for the US Department of Energy’s carbon sequestration program, with a pending budget request of 9 million carbon capture and storage (CCS) , a technology that is indispensable in dealing with concerns about energy and climate.

The US government committed to the goal of stopping the growth of carbon dioxide and carbon dioxide-equivalent greenhouse gases by year 2025, and thereafter, to reverse it : an objective which further underscored its 2002 commitment to reduce the carbon intensity of the US economy by 18 percent by 2012.

All these efforts lead to the US Energy Departments’ positive pronouncements, amidst the worldwide economic crisis:

“Robust investments in advanced technologies and global cooperation to advance alternative energy sources benefits the international community by enabling developing nations to “leap-frog” over some of the prevalent and dirtiest fossil-fuel-based technologies to a diversity of cleaner energy options to power economic growth.”

Year after year , top government officials worldwide, heads of global organizations, leading environmentalists and the largest international investors meet in  international summits  to discuss, debate and plan the future worldwide alternative energy in a myriad of summit events in different parts of the globe.

The summits come on strong as catalysts to change, international and regional enablers , active platforms for senior policy decision makers and global leaders in initiating and accomplishing worldwide reforms on alternative energy, big investments and high-level business deals, and global projects on sustainable energy systems.

Unlimited and vast financial investment opportunities , frontrunning international efforts to expand the global market for sustainable and renewable energy, everything up for grabs in these auspicious gatherings.

Summit delegates look forward to developing local energy sources , focusing on their quest for energy security, intensifying their engagement with governments and development financial institutions to encourage business and finance models and increase the chances of investments in sustainable energy infrastructure, offering additional possibilities for global exchange within the renewable and energy efficiency sectors.

Further, the call is on for both industrial and scientific communities and also the public forces to join the efforts to surmount the still existing or new arising barriers and obstacles in the quest for alternative energy sources , and to meet the challenges for achieving a fast breakthrough to market applications . 

The worldwide alternative energy summits offer a platform among the best global industry experts, influential leaders and the biggest decision makers in the international business community as they map out action plans, objectives and goals to confront the challenging demands for for sustainable and global energy, discover technological advancements and possibilities about the entire spectrum of alternative energy and energy efficiency technologies, and what is in store for the global market as it thrusts forward in the exciting and progressive 21st century. 

Meantime, University of Western Sydney’s solar energy banner says it all, giving us some valuable food for thought for our 21st century future.   “Solar energy has supported life on earth for millions of years. It may be used to support life forever.”

Hybrid Cars – Technology Of The Future Or Passing Fad?

Hybrid cars have been getting a lot of buzz the last three or four years, and now with the soaring cost of oil and gasoline, hybrids are expected to get hotter than ever. Here are some Questions and Answers about hybrids.

1. What is a hybrid car?

A vehicle is a hybrid when it combines two or more sources of power. Hybrid cars almost always have a gasoline engine and an auxiliary electric motor system that runs off rechargeable batteries.

We normally assume that the point of hybridization is to save fuel, and that is definitely the case with most of the smaller compacts and sedans. But in fact some of the more upscale hybrid models are more concerned with boosting power and “performance” without the usual loss in fuel efficiency.

2. Do you have to plug your hybrid in at night?

You may assume because a hybrid car runs part of the time off its battery pack, that it is necessary to plug it in at night and recharge the batteries (like a golf cart!). But this is almost never the case. Hybrid cars recharge their batteries “on the fly” by making use of unused energy which is normally wasted during normal driving.

For instance, most have a system that captures some of the energy used while applying the brakes, and converts it to electrical energy to charge the battery. This is called “regenerative braking”.

If hybrids had larger battery packs that you could plug into the electricity grid, they would be able to transfer more of the vehicle’s power requirements over to the electric motor(s), and use even less gasoline. But most auto makers have been unwilling to go this route, arguing that today’s batteries could not take the extra load and more extensive usage.

3. Do you have to replace the batteries?

The short answer is No. Hybrid batteries typically have an 80,000 – 100,000 mile warranty. The U.S. Department of Energy tested them to 160,000 miles and stopped testing because they still performed almost like they were brand new. Some taxi drivers have gone more than 200,000 miles in a Toyota Prius without battery problems.

In any event, since hybrid battery packs have hundreds of cells, individual cells or modules could be replaced if there was a problem.

The best way to keep nickel metal hydride batteries performing at their peak is to keep their charge between 40% and 60% — never fully charged and never fully drained to zero power.

4. How long have hybrids been around?

Alternatives to the ICE (internal combustion engine) in automobiles have been around since at least 1900. The first patent for a gasoline-electric hybrid vehicle was filed in 1905. Alternative fuel sources were wiped out as a result of two things. First was the development of the electric self-starter (in 1913) that made gasoline driven cars much easier to start.

The second development was the advent of the age of cheap oil that started around the time of the first World War. This completely removed the economic incentive to look for alternative fuel sources. This is only starting to change now, 80 years later.

5. Are hybrids expensive to purchase?

In January, 2006, there were 10 different hybrid models available from ,000 to ,000. The most popular models — the Insight, Civic, and Prius — are less than ,000. According to auto maker announcements there should be more than 50 models available by 2010. As sales and production increase the prices should not be significantly more than for standard ICE models.

Even with the slightly higher average cost for a hybrid — usually around ,000 — these additional initial costs can be offset by federal and state tax incentives, lower maintenance costs, and exceptionally strong resale values.

6. Are hybrids small and underpowered?

Initial hybrid models emphasized fuel economy, so were much lighter vehicles, and had smaller engines. The objective was to offset the loss of power in the ICE with additional power from the electric motor. This would result in essentially the same level of power while burning less fuel.

But this principle does not have to result in underpowered vehicles. In fact the Lexus Rx400h and Toyota Highlander Hybrid both have a 270 horsepower power system. And the Lexus GS 450h hybrid sedan is expected to have more than 300 horsepower and go 0-to-60 in less than six seconds. Taking the quest for hybrid power even further, the Toyota Volta concept venicle has a 408 hp power plant.

7. What is the main reason people buy hybrid vehicles?

Saving money on fuel is the first thing most buyers think of. But, in fact, the amount saved on fuel over the life of the vehicle may not equal the extra purchase cost of the hybrid.

There are obviously other factors at play in the gradually building popularity of hybrids. Some people want to make a “green” statement, others simply want to be the first on the block with a new and promising technology.

8. Will hybrid technology save the environment?

There’s no doubt about it. Hybrids are becoming more popular. In the past five years hybrid sales in the U.S. have grown 2000 percent. Sales in 2000 were 9,500, and by the end of 2005 had grown to over 200,000.

But even this larger number is just 1.2% of the 17 million new cars sold last year. If every hybrid gave double the current fuel economy, from an average of 20 mpg to, say, 40 mpg, that would save roughly 100,000 gallons of gasoline a day. But that amount pales in comparison to the total daily gasoline consumption in the U.S. — 400 million gallons! The savings of 100,000 gallons would bring that number all the way down to … 399,900,000 gallons.

Not very significant. Obviously governments and auto makers will have to start getting very serious about hybrid technology before it will make a significant difference.

9. Does that mean hybrid technology is only a fad?

No it does not. Because the only way towards a sustainable future is to find a combination of fuels that will reduce our almost total dependence on oil. Hydrogen fueled vehicles will be part of that future, as will fuel cells, deisel, and alternative fuels such as ethanol.

But what is almost certain is that every promising solution will involve some kind of hybrid combination of technologies. So today’s hybrid vehicles are an important and necessary step towards a much more promising and sustainable future.

Future of Hybrid Cars

By: anonymous
Posted: Jan 26, 2007

]]>

There are many design concepts being considered for maximum public exposure and benefits on the drawing board of car designers today that look to the future hybrid car needs and considerations that will serve the public well in the course of the next century. Many of these hybrid car designers are taking past and proven sales performers and have begun reworking their designs from the ground up.


Instead of a front wheel drive platform, there are automobile designers that are building on a rear platform design for one of the nation’s best selling and widely recognized car frames in America and worldwide. The hybrid car designs of the future are including sports car models that have been all-time favorites with the world in the past and are now being revived with the brand new hybrid engine in mind.


There is an aggressive training program in place at one of Americas largest car manufacturing companies that is preparing their technicians to repair the growing styles and variations of hybrid cars that are emerging onto the automobile market.


With the extreme difference in battery features and dramatic variance in voltage levels, there is a void that needs to be filled by someone who is equipped with the necessary battery cabling devices that can handle 270 volts instead of the normal 12 volt battery systems. Regular car technicians are typically capable of handling battery recharging requirements, but with the futuristic applications that are applied in hybrid battery design, the best service these car technicians can provide at present is that they can still provide oil changes and tire rotations should the need arise.

With a mindset of grasping and expanding the propulsion features that are somewhat limited in today’s hybrid car designs, there are retro styling efforts that are focusing on providing hybrid cars with optional V8 engine capacities.


There are considerations in place to use solar cells in the framework of hybrid automobiles. The electrical power will be produced through the boot lids and bonnet placement of these solar cell modules. Through the use of solar cells it will then be possible to utilize the battery charging capabilities when the car is not turned on or in motion to replenish batteries that have been depleted through the use of air conditioning or through continuous operation when the hybrid automobile is delayed in traffic jams at different times of the day. This lightweight body structure design would benefit the energy savings to the consumer and make the car more manageable on the highway.


There is an effort in hybrid car design that is turning the out of the ordinary hybrid vehicle into a replica of what is parked in the driveway every day of our life. This blending in effect is meant to bring the hybrid full circle into the acceptable graces of the American public.


The future hybrid car will need to focus more on greenhouse gases that negatively effect the environment as well as a hybrid car that will be even more fuel efficient. Without these changes, the production and sales of any type of vehicle will not be possible due to the degradation of our atmosphere.


There are many views about hybrid cars in the futures that will change its fuel source from the heavy duty batteries in use today, to hydrogen-power fuel cell. This will take away the need for hybrid cars to have to use gasoline completely in order to transverse down the major highways.
