Toyota Camry Hybrid: The Green Car

With gas pricing soaring up, the popularity for the hybrid vehicles are showing an increase. Many car makers have come out with attractive hybrid models. The Toyota Camry Hybrid is one among the most popular of these choices. Let us have a look at the gorgeous features of the Toyota Camry hybrid that makes it stay apart from the other hybrids.

Even though the Toyota Camry hybrid is exactly the same as the previous

Camry sedan models in many aspects, the new Hybrid models possess some features that differ in some ways. As Hybrid cars run partly by electricity and the rest by gasoline, there is no denial that there would be positive outcome. But of course there do have a serious of negative impacts also. Camry hybrid’s later models, such as the 2007 was classified as a “full hybrid” because it could run on gas or on electric energy, depending on the driver’s preference.  Nowadays, the combination of both is considered to be more popular and more and more people are considering investing in these models.


The sales of Toyota Camry hybrid are currently remarkably high. Toyota, the Japanese automaker is doing their best to annex a big part of the market. For this, a massive and research is being conducted to develop the existing specification of the Camry Hybrid. Hybrid is either superior or just within the average level. The Toyota Camry hybrid has a 40 MPG gas mileage while if the highway it has 38 MPG gas mileage. It moves utilizing a four-cylinder engine with gasoline fuel. The maximum capacity of its NiMH 245V battery is about 30 kilowatt or 40 horsepower, peaking at about 192 horsepower or 140 kilowatts. Toyota Camry Hybrid is capable of matching the acceleration speed of the Toyota V6 Camry. The car won the award for the Green car of the Year as well as the Eco-Friendly Car in 2007. Thanks to the ability of low consumption of fuel.

Prius Tops 2009 Fuel Economy Ratings


The EPA and Energy Department this week issued its 2009 fuel economy guide. Hybrids, once again, dominate the top of the list with five of the six most efficient vehicles. The 2009 Toyota Prius is the leader with ratings of 48 mpg in the city and 45 on the highway.

There are two new entries on the Top 10 list: the diesel-powered Volkswagen Jetta TDI sedan and wagon, and the Smart ForTwo convertible and coupe. The Smart ForTwo is number five on the list, with a rating of 33 mpg city and 41 highway. The Jetta diesels are now capable of passing strict emissions guidelines in all 50 states. The Jetta with a manual transmission is in the No. 7 spot with 30/41 mpg, followed by the automatic version at 20/40 mpg. The manual-transmission Toyota Yaris, and the automatic version, round out the Top 10 list.

The outlines of the 2009 list give a clear picture of the most effective fuel-efficiency strategies available today: hybrid gas-electric technology is at the forefront, followed by clean diesel and small cars.

Top 10 Fuel Economy List for 2009 Vehicles

  1. Toyota Prius - 48/45
  2. Honda Civic Hybrid - 40/45
  3. Nissan Altima Hybrid - 35/33
  4. Ford Escape Hybrid FWD; Mazda Tribute Hybrid 2WD; Mercury Mariner Hybrid FWD - 34/31
  5. Smart ForTwo convertible; Smart ForTwo coupe - 33/41
  6. Toyota Camry Hybrid - 33/34
  7. Volkswagen Jetta (manual, diesel); Volkswagen Jetta SportWagen (manual, diesel) - 30/41
  8. Volkswagen Jetta (automatic, diesel); Volkswagen Jetta SportWagen (automatic, diesel) - 29/40
  9. Toyota Yaris (manual) - 29/36
  10. Toyota Yaris (automatic) - 29/35

Mercedes-Benz eco C-Class tells you when to shift gear


A new greener version of the Mercedes-Benz C-Class will tell drivers when to change gear to save fuel. Using a computer and display that informs drivers of the most efficient time to shift gear, the C 250 CDI BlueEFFICIENCY Prime Edition hopes to maximise mileage from its efficient diesel engine.

The C 250 will cost 40,638 Euros (£32,330) and goes head-to-head with compact executive cars such as the BMW 3 Series 318d.

Mercedes-Benz says its car will manage 138g/km CO2: not bad, but not as good as the class-leading Beamer. Performance looks respectable, with a promised 0-60mph of 7 seconds.
The car will be available this autumn in a limited 5,000 run.

SHIFT: Hydrogen fuel cell vehicles are a fraud


Who wouldn’t like the idea of a fuel cell car running on clean, pure hydrogen, the universe’s most plentiful element? Its byproduct is sparkling, drinkable water, with none of that pesky pollution spewing out the tailpipe. And then if there's any energy left over when you're done driving, why, you could use that car's fuel cell to power your house! We can get rid of gasoline! And fuel cells, hey, they use those in spacecraft, don't they? This is some modern stuff, and at first glance, hydrogen appears to be a viable solution to all our energy problems.

Well, think again. Hydrogen fuel cell cars are a dumb idea, and those who are pushing them are frauds. They want to advance their own agendas, and couldn’t care less whether their cars are practical or not. They just want to make more money. In fact, their tired ideas for fuel cell vehicles have already been left in the dust by electric and hybrid vehicles, and there are a lot of good reasons why.


Not for Sale
Fuel cell cars are available today. But wait, you can’t really buy the Honda FCX Clarity — you must rent it for $600 a month. Why? Because if this wasn’t a publicity stunt, you’d have to buy the FCX for its real cost. The car makers are secretive about how much it's costing to build these vehicles, but you can bet it's well into the hundreds of thousands of dollars apiece.

To give you an idea, mass producing a fuel cell-powered bus is going to cost $200,000 extra just for the engine, according to its designers at Caltech and the Jet Propulsion Laboratory. Pretty good, though, considering that just two years ago, the average cost of a fuel cell vehicle was a cool million dollars.

This huge cost issue is just the tip of this expensive iceberg. While some companies that are seeking funding for their fuel cell vehicle schemes say otherwise, the cars are notoriously impractical. I smell boondoggle.



Is Hydrogen a Fuel?
No, hydrogen is not really a fuel, but an energy storage medium. It's more akin to a battery that soaks up energy when it’s extracted from something else, and then delivers that energy when it’s used. And, it takes a lot of energy to create that hydrogen. The energy must come from other sources, such as natural gas, or elaborate electrolysis using platinum membranes that separate the hydrogen and oxygen in water, using, um, electricity. What? Using electricity to make hydrogen that's then turned back into electricity? Yes, it’s the laws of physics at work, where you have to put in energy to get some out. So you must use electricity or gas (or maybe solar energy) to make this stuff. So yeah, it works like a battery, except a whole lot more expensive. Why not just charge up an electric car instead?


Can’t we just mine hydrogen from the ground?
No, there's no such thing as a hydrogen well. It doesn’t just gather in one place like oil or natural gas does, but quickly dissipates into the atmosphere because of its simple atomic structure. Because of that number-one position on the periodic table, hydrogen is difficult to store and corrodes pipes. It’s a clever escape artist, and can even slip between the molecules of steel or aluminum containers. So hydrogen can't be stored long-term — it must be created on the spot by stripping it from other molecules.

These fuel cell cars need four times the volume to store an amount of energy equal to that of gasoline. Even though the energy-generating equivalent of hydrogen is lighter than its gasoline counterpart, you need a 60 gallon tank to store the same amount of energy that’s in 15 gallons of gasoline. These cars won’t go far before it’s time for more hydrogen.


Where will you get that hydrogen?
The oil companies would like to provide the infrastructure for such a “hydrogen economy.” The oil companies say to you, "No, don’t use electricity from your house to charge up that electric vehicle — depend on the oil company’s filling stations to get where you want to go, as you’ve always done."

Good luck with that, though, because so far there’s just one retail hydrogen station in the U.S. (run by, you guessed it, an oil company), far short of the thousands needed to make this hydrogen economy anything more than a pipe dream. The other experimental stations are nothing but showboat propaganda fronts that expend far more energy than they create. Anyway, the oil companies would be happy to invest in that costly infrastructure, because they know they'll get their money back. But it'll be coming out of your hide, just like it always has.


Plenty of Guff
There are a variety of impractical ideas for using hydrogen to propel cars, but they're years — and maybe even decades — from being cost-effective. Most of these schemes seem to suspiciously somehow involve the oil companies keeping their greedy paws in the “hydrogen economy.” To give you an idea, one great proponent of the “hydrogen economy” is energy expert, former oilman and conservation guru George W. Bush.


Somewhere Over the Rainbow
We're all for innovation, but the fantasy of cost-effective hydrogen fuel cell vehicles is just a distraction from the real work that needs to be done: perfecting electric and hybrid natural gas/electric vehicles, charged by electricity generated by clean and renewable nuclear, solar, wind, geothermal and hydroelectric power. These technologies are here now, and the associated batteries are getting more efficient at a rate that’s significantly faster than the snail's pace of impractical fuel cell technology. Maybe someday hydrogen fuel cells will be practical for personal vehicles, but not today, and not for a long time to come. Don’t be fooled by the self-serving frauds that keep trying to tell you otherwise.
