Over time, the media has elevated the popularity of various vehicles by highlighting some of the fictional rides that have graced the pages of novels, the lyrics of songs, the 30-minute TV show, and the silver screen. Whether Fred and Wilma are peddling around in their signature rockmobile, James Bond gets away with his gadget cars or the Beach Boys bring life to the Little Deuce Coupe, it’s sometimes hard to forget that many of these fictional cars really don’t exist. Below are a few examples that have gained fame throughout the years.

Batmobile

In both the Batman television shows and movies, the superhero-on-the-go often hopped into a sleek, customized vehicle that provided protection for his Bruce Wayne alter ego. Equipped with heavy armor plating and a high performance engine, the evolution of the Batman series displayed increasing levels of gadgets. To reach increased speeds, the Batmobile sometimes offered rocket boosts, while additional weapons and a computerized assistance helped to keep villains at a distance.

KITT

The talking car that aided David Hasselhoff’s character, Michael Knight, navigate through a sea of enemies and bad guys was a Pontiac Trans Am. The television series focused on a high-tech approach to entertain the audience. Numerous fans watched the show just to see what KITT would do or say next. The popularity of the show even helped to boost Pontiac car sales as the verbal wonder could drive without a passenger and even displayed its own set of entertaining stunts.

Christine

Stephen King has produced numerous novels that have become popular movies; the same is true with the 1958 Plymouth Fury that seemed to have a mind of its own. Christine was the name given to the car that appeared in the horror novel (with the same name) published in 1983. Driven by supernatural forces, the antique auto created havoc in both the novel and the movie.

Herbie

Several Disney movies and cartoons have focused on Herbie the Lovebug, which was a Volkswagon Beetle that made its first appearance in 1969. Just like Christine, the red, white, and blue striped car with a “53” on its side could also drive without assistance and had a reputation for acting on its own. Most of the time, the car was featured in some sort of racing competition.

General Lee

The television series and movie named the Dukes of Hazzard showed main characters, Bo and Luke Duke soaring through the air, causing mischief with their get-rich schemes. Their vehicle of choice was a colorful Dodge Charger that allowed the cousins to complete high jumps in almost every episode. The car is also known for its controversial Confederate flag decoration.

With the introduction of the first Grand Cherokee, Jeep defined and created the luxury sport utility vehicle (SUV) market, but in spite of this grand tradition the model is currently experiencing some difficulties. Jeep not only defined what an SUV was, it was the SUV market in the USA with the inception of the Cherokee and later on Grand Cherokee. This is no longer the case. The growing list of strong competition has intensified, and along with high fuel prices, this has lead to some serious challenges to Chrysler in spite of Jeep’s combination of legendary 4×4 capabilities, on and off-road refinements, and technological innovations.

The Jeep Grand Cherokee was one of the pioneering SUVs that ushered in the modern SUV market in the early 1990s. When it debuted, the Grand Cherokee represented a bigger and more refined version of Jeep’s smaller but popular Cherokee. The company’s designers wanted the Grand Cherokee it to be maneuverable enough for city driving, roomy enough for the whole family, stylish enough to take out on the town and rugged enough to reach those remote camping areas. The Grand Cherokee certainly met all of these requirements and, we feel that Jeep continues with this tradition in its current Grand Cherokee version.

The 2005/2006 version of the Grand Cherokee, which is the model’s 3rd generation, is one of the best SUVs made, and as one critic put it “arguably the most desirable”. With some of the outstanding available features of full-time four-wheel drive, independent front suspension, rack and pinion steering, a five-speed transmission, and an available 5.7-Liter HEMI V-8 with MDS, which deactivates up to 8 cylinders when not needed for better gas mileage performance, the Grand Cherokee is featured packed. Safety features include Electronic Stability Program, SmartBeam ™ headlamps that automatically and quickly adjust high-beam brightness and intensity, All-Speed Traction Control System, and advanced multi-stage air bags with an Occupant Classification System. The look and feel of the body was also updated to give it an edgy angular look, which looks new and contemporary while retaining that Grand Cherokee style with the famous 7-slot Jeep grille. Chrysler also gave the Grand Cherokee an updated suspension system that delivers better corning turning performance and a tighter turning radius.

In spite of these top-of-the-line features, Grand Cherokee sales in the USA for 2006 (ending December 31, 2006) were 139,148 units, which were down from 213,584 in 2005. This represents a decline of 35%. Jeep’s smaller SUV, the Liberty, also saw its numbers drop dramatically in 2006 with unit sales of 133,557 versus unit sales of 166,883 for 2005, a 20% decline. While it doesn’t necessarily make Chrysler feel any better, they were not alone in decreased sales in the SUV segment. Other USA car manufacturers also experienced declines. Ford experienced a 25% drop in its SUV sales for the USA, while GM’s truck sales were down 9.6% (2,499,269 for 2006 versus 2,765,809) (detailed performance reports for GM’s SUVs was not available). The decline in SUV sales, especially mid-range models, was affected by the dramatic price increases in gasoline during 2006. This along with luxury SUV models by BMW, Lexus, Mercedes, and Porshe, and mid-priced SUVs by Mitsubishi, Toyota and others experiencing a surge in popularity is creating a sizable challenge to Chrysler. With its outstanding features, Jeep tradition, and the Daimler-Chrysler technology behind it, we look for the Grand Cherokee to make a strong return in the future.

OK - You’ve been putting off replacing those tread thin tires. Face it, replacing tires is a downright aggravating experience. Shopping for tires rests somewhere between doing your taxes or doing house cleaning. A dentist’s waiting room, while you’re hanging on anticipating that root canal, is unlikely to increase your anxiety. But, the bleak condition of most waiting rooms at tire dealers all too often propels us into an ambiance bordering on the repulsive.

Throughout our lives, the majority of us who drive will no doubt spend more than at least a day out of our lives marking time in a succession of these dismal dens. And then, we’re left to pore over long outdated, pawed over magazines offering little worthy of our attention.

We tend to think of tires like we think of electricity. Electric power is taken as a given. Only if it shuts off, are we really forced to think about it. We’re rudely reminded of our dependence on it when we lose it.

Our lack of consciousness about our tires is identical. Ignoring them seems to be the norm. All is well until we get a flat or blowout. All of a sudden we have to interrupt whatever we’re doing. We can’t get to a movie, miss picking up the kids or won’t make yoga class. Or much more seriously, one of our tires gives out and causes an accident. It’s not difficult to imagine any number of similar disruptions.

Fortunately, tire makers today are consistently improving tire performance and safety. Nevertheless, we, as car owners, have to cooperate. All things mechanical can only take so much wear and tear. Although excellent quality standards are built into tires today, they do have their useful life. It’s up to us to provide ongoing maintenance in the form of correct tire pressure, regular rotation, proper alignment and balancing. Even though we may be scrupulous about tire maintenance, there will come a time when we simply have to replace them. We dread the root canal and we dread the tire dealer.

How about a little surprise? A lot of the aggravation in replacing tires can be bypassed.

To the rescue come the good people at websites such as The Tire Rack. Your computer becomes your tire store while you sip a cool beverage in the comfort of your home or office. That’s right. All you need to do is log on. Now that’s convenience you might not otherwise expect when buying tires.

Here’s the rub. If you’re shopping for Bridgestone, Michelin, Dunlop, Goodyear, Pirelli or any other major tire make, The Tire Rack maintains and ships a full inventory of tire sizes and models. An easy to use “search widget” will permit you to locate readily the right size and tire model for your make and year of car, truck or SUV. ATV tires are available, as well. You can peruse tire reviews.

There’s more. The Tire Rack has made arrangements with tire dealers in your neighborhood to receive shipment and install them. If it’s more convenient for you, The Tire Rack will ship to your office or home.

You’ll want to consider these efficiencies when you buy tires online.

1. Save time shopping online.

2. You’ve selected the right tires.

3. No waiting at the dealer to complete the purchase.

4. Receive the tire maker’s full warranty.

5. Less interruption to your busy schedule.

6. You’re more likely to do it right now while you’re thinking of it.

Wait! There’s an even better idea. Have The Tire Rack mount your tires on a new set of wheels ready to stick on your vehicle. Very few things can rehab a worn looking jalopy better than a brand new set of tires and wheels.

RC nitro monster trucks may very well be the fastest growing segment in the world of RC vehicles. The reason for the surge in popularity probably stems from the fact that RC nitro monster trucks have steadily improving in performance over the years. In fact, the latest models can actually outperform many RC cars.

RC nitro monster trucks can be bought either ready to run or in a kit that allows you to actually build it yourself. Both types are quality vehicles, built for strength and durability.

In fact, RC nitro monster trucks can handle an amazing amount of hard driving and even though they appear top-heavy and ready to roll over at any moment, the truth is that they rarely do roll over. This is because the wheels of RC nitro monster trucks are designed to provide a low center of gravity.

For many people, the appeal of RC nitro monster trucks is that they mirror the abilities of their real-life counterparts. The enjoyment of watching monster trucks comes from watching them ride roughshod over any kind of surface, including other vehicles. Well, RC nitro monster trucks can be let loose on the kinds of terrain that would leave other RC vehicles spinning their wheels. And, yes, if you ever get the opportunity, you can drive your RC nitro monster trucks right over your friends’ little RC cars.

Although you might think that all RC nitro monster trucks are 4-wheel drive, you’d be mistaken. There are 2-wheel drive RC nitro monster trucks available, and even some that give you the option of switching back and forth. Just as in real life, the 4-wheel drive model allows for driving over areas that are rougher or steeper than the 2-wheel drive model could handle.

So why would anyone want 2-wheel drive RC nitro monster trucks then? Well, while the 4-wheel drive allows for more flexibility in where you can take it, the transmission system is also more sophisticated. Since engine maintenance is routinely required to keep any RC nitro vehicle running in peak condition, expect to spend more time and effort with a 4-wheel drive transmission.

But this drawback shouldn’t be a deciding factor when choosing from among the various models of RC nitro monster trucks. Engine fine-tuning has never been easier for nitro RC vehicles. A bigger concern will probably be price. RC nitro monster trucks may have gotten their name from their appearance, but they could just as easily have earned it from the size of their prices.

Here’s the skinny: don’t expect to purchase one of these babies for less than $300. And, frankly, only expect that price from an older brother looking to sell his RC vehicle so he can raise money to buy a real vehicle. Seriously though, although unexpected bargains have been lucked into on eBay or by someone listing one for sale on a message board, brand new RC nitro monster trucks typically list for well over $400.

All modern car tires are now radial. Car tires are a tremendous blight on the environment, and there are about a billion car tires stockpiled in our country. Re-treaded passenger car tires are manufactured according to standards. Today’s passenger-car tires are safer at much higher speeds than 80 mph. While passenger-car tires are nearly all radials these days, ST tires are still available in bias-belted construction. We all know that our car tires are filled with air and that at certain times the air pressure in them decreases. The sport car tires are built to provide excellent traction and handling.

This standard specifies performance, labeling, and certification requirements for retreaded pneumatic passenger car tires. Higher-performance tires have softer, grip pier rubber with shorter tread life. There are quite a few levels of performance tires available on the market, from full-on race tires to general use passenger car tires. There are various types of performance tires that are sold in the market. Performance and luxury touring tires are quiet and handle incredibly well, sometimes it is hard to believe that these types of tires are having the ability to produce results like this. When using performance tires they tend to wear out quicker than usual everyday car tires that you would put on family cars. The largest accelerations that most high-performance car tires can withstand without breaking static friction are on the order of 0.

In the simplest of operations you can determine your chosen car or off-road vehicle and subsequently mount the rims of your choice visually on the vehicle. Plus-sizing is an option that allows vehicle owners to customize their vehicle by installing lower aspect ratio tires on wider- and larger-diameter rims. Lightweight metal rims are also available on the market.

The speed ratings of Goodyear passenger car tires are listed on the "Sizes Specifications" pages in the Car/Light Truck Tire Catalog. The materials and tooling Goodyear has developed to build its race tires help it build better passenger car tires.

All passenger car tires are all made from the same radial base so there is no need to sell in "balanced" sets as you put it. Car tires are cheap; you can pick up a used one just about anywhere. Your speedometer won’t read the correct speed if your car tires are not the right size. One important fact is that many automobile passenger tires are not intended to maneuver the car out of problem with speeds in excess of 75-80 mph. Make sure your car tires are in good condition and maintain a full tank of gas. Today’s car tires are built from steel and rubber which gives the tires the ability to last longer. Everyone knows car tires are inflated with air at high pressure to maintain their shape and will deflate when punctured.

When choosing a car tire it is best to speak to the dealership or auto mechanics to get their opinions on which tires are good for you type of car.

If you are a prospective car buyer, finding just the right car for you is a decision not to be made lightly. Everyone’s needs are different and when you factor in personal tastes, there’s just no telling what will push you into making the final decision.

It’s easy to get carried away when you shop for a car: the smell of the brand-new upholstery, the satisfying purr of the motor, not to mention the slick salesman promising you outrageous deals, all conspire into making you part with your hard-earned money. Hopefully you will find a great deal for the amount of money that you are willing to pay. However you put it though, buying a car will cost a fair amount of money; you do want a car that is in decent condition and that will last for several years don’t you? It is of utmost importance then to do research on the particular models you are most interested in, know the current market trends in car sales and weigh your options carefully so you are confident of making the right choice when it comes time to whip out your checkbook.

The type of car you choose will be dependent on several factors: are you looking for a roomy, comfortable way to truck your kids to ballet class or soccer practice or are you searching for a rugged, off-road trail warrior who willingly follows were your adventurous spirit leads? Maybe you want to tear it up at the racetrack in a screaming blaze of high-octane performance or perhaps gas mileage and ecological-friendliness are your primary concerns. Either way, consider what your expectations and projected requirements are for your planned vehicle and anticipate your need in the future. You’re family may grow beyond it’s current size or you may have a need to use your vehicle for an expanding business. Think of what’s best for your needs and choose a solid, practical model; this year’s flashy, 2-seater with day-glow paintjob and shiny designer rims might get your pulse racing but is it really what you need and can use many years down the line?

Get up-to-date on the latest models though, so you at least know what’s out there and get a feel for current market rates. Check out what new features and innovations have come out recently; the automobile industry is a fast-paced one and new enhancements are coming out all the time.

Luxury car is a term that is widely used, but does anyone truly know what it means? When it comes to cars, luxury is in the eye of the beholder. What a car dealer’s ad touts as luxury may be different from what a car rental agency categorizes as a luxury car, and both may conflict with your personal perception of what a luxury car is.

In economics, a luxury item is one that is in higher demand among people with higher incomes. A luxury car is a status symbol, and status varies depending upon the socioeconomic or demographic group to which is applies.

A luxury car may simply mean a high-priced car. A luxurious car may not necessarily be considered a luxury automobile. For example, because of its high price, a Hummer is often considered a luxury car, even though the original Hummers are heavy duty military trucks without emphasis on comfort.

A luxury car may also simply be an automobile made by a manufacture known for making luxury automobiles, even if the specific vehicle is less expensive than its usual models. For example, all models of Mercedes and Jaguars are considered to fall into this category, even the least expensive versions.

Most people would agree that an automobile costing more than $100,000 would be considered a luxury automobile. Almost all cars made by Rolls Royce and Bentley, for example, fall into that price range. Exclusivity is on of the few agreed characteristics of a luxury vehicle.

Typically, luxury automobiles enhance comfort and operation. Leather, adjustable, heated seats are an example of luxury appurtenances. High-performance vehicles such as sports cars, for example Corvettes and Vipers, are prestige autos, but not everyone would call them luxury vehicles. An automobile may be luxurious by virtue of its amenities and its comfort level without being expensive, even though to most people a luxury means something they really can’t afford.

The cold air intake system was launched in the late 1980s. This system includes intake tubes which are made up of molded plastic, and a cotton-gauze air filter. A cold air intake system is used to increase the power of your car, truck or SUV’s engine, by reducing the temperature of the air going into it. These aftermarket parts are available in different colors and sizes, as another objective of this system is to enhance the look of your vehicle’s engine bay and also to create an attractive intake noise. Installing a cold air intake is an inexpensive way to increase the performance of your vehicle.

A cold air intake system is responsible for increasing the amount of oxygen, which is necessary for combustion along with fuel. It provides cold air to the hot engine and protects your vehicle from mechanical imbalance.

While purchasing a cold air intake, you have to take notice of the following points:

• The diameter of the air intake should be big for free flow of air. • Interiors of tubes should be smooth to reduce the blockage of air. • Air filters should be efficient.

Different materials like plastic, metal, silicone, fiberglass or carbon fibers are used to make cold air intakes.

A short ram air intake is the alternative to a cold air intake. It comes with a short metal or plastic tube with a conical air filter, and is fitted inside the engine bay. Because it increases the airflow to the engine, a short ram air intake is more effective than the stock air intake. In some cases however, the hot air from around the engine can reduce performance, but the use of a heat shield will solve this problem.

Carbon fibers can replace metal for piping, as this reduces weight and insolates air at a higher speed.

Most cold air intakes come ready to install, and you can quite easily fit one yourself. It’s simply a matter of removing the stock air intake system from your vehicle and installing the new cold air intake. The air will enter from an external source - from the front bumper, fenders or a hood scoop. By providing increased airflow at a suitable temperature, the cold air intake can prove its credibility.

These cold air intakes are not as effective in rain as in other seasons. This is because during the rainy season, the flow of air is not proper. There is also the problem of your air intake being exposed to water. Too much water ingested into the engine will cause serious damage. To bypass this problem, you can install a water shield or relocate the air intake so that it is inside the engine bay.

In upshot, it is a good idea to use a cold air intake in your car or truck, as it will result in improved performance and better gas mileage also.

A popular joke in the 1960s at full service gas stations was "filler up with Ethel and change the air in my tires." Today with the price of gasoline approaching $3.00 per gallon, why not replace the air in your tires. Not with air but with nitrogen. Filling your tires with nitrogen rather than air will improve gas mileage, help maintain correct tire pressure, keep tires 25% cooler, improve handling and performance and prolongs the life of your tires. NASCAR drivers use nitrogen in their tires for safety reasons, you can too.

Why should you stop putting air in your tires! Compressed air you find at tire shops, gas stations and the compressor you use at home have a high concentrations of water vapor. Compressing air concentrates the water in it and unless really efficient air dryers are used chances are there is water vapors in your tires. Water vapor absorbs and holds heat. This wet air plus heat can increase the pressure in your tires, causing highway blow outs, and is one of the reason you should check your tire pressure when they are cold.

This article is not about the nitrogen. It’s really about reducing oxygen and water vapor in your tires. The air in our tires is composed of 78% nitrogen, 21% oxygen and about 1% water vapor and other gases. When pure dry nitrogen is used to replace the air in your tires it improves fuel efficiency, handling and it will extend the life of steel rims or custom wheels and tires. By reducing oxygen and water vapor in your tires from 22% to less than 7%, your tires will maintain pressure three to four times longer. Plus it will keep you safer on the highway.

How does oxygen and water damage my rims and tires? Oxygen, especially at high temperatures and pressures, corrodes aluminum, steel wheels and rubber. This process is called oxidation. When oxidation occurs small particles of rust and aluminum oxidization in your steel or aluminum wheels can clog valve stems, causing them to leak. The oxidation can cause the surfaces of your wheel flange and tire beads not to seal properly causing another leak point.

Oxygen can also age the thin layer of rubber called the inner liner or radial ply. As the inner liner ages, more and more air migrates through the rubber, causing additional pressure losses. As oxygen migrates through rubber it can come in contact with steel belts and the steel bead causing them to rust.

While both nitrogen and oxygen can migrate through rubber, nitrogen does it much slower. It might take six months to lose a couple of pounds of nitrogen, compared to less than a month with wet compressed air. Dry nitrogen does not cause rust and corrosion on steel rims or aluminum custom wheels, and it does not degrade rubber like wet compressed air.

Where can I get nitrogen for my tires? Nitrogen is becoming very popular with long haul trucking. Some truck stops have nitrogen available for these big rigs either free or by paying a small fee. They use the same type pay stations that you see at gas stations except they are marked "Nitrogen". These nitrogen stations are then connected to large nitrogen cylinders near by.

You can also buy your own small inexpensive Nitrogen Tanks and have them filled at welding supply stores in your area. Another source for small nitrogen tanks is Paint Ball supply stores either local or on the internet. eBay is a good source. These small nitrogen tanks can be filled at welding supply stores and then easily plumbed to fill your tires. Use caution when handling these small nitrogen tanks as they can be filled to as much as 3000 psi. Also make sure the nitrogen tank you purchase has a regulator attached and it is set for about 50 psi.

Filling your own new tires with nitrogen is a simple process. Jack up one tire until it just clears the ground, remove the tire valve stem and allow the air in your tires to escape. Once all the air escapes install a new valve stem. Then simply fill your tires with nitrogen from your small nitrogen tank. Repeat the process with the other 3 tires. Do not forget your spare! Your tires should now have about 95% dry nitrogen and you have significantly reduced all the hazards and oxidation problems mentioned above.

If you own a tire store and would like to provide nitrogen for your customers buy a Ingersoll Rand Nitrogen Tire Inflation System.

Make no mistake about it; your truck is an extension of who you are. You put a lot of work into making sure your ride projects exactly the right image for your personality. But despite all of your efforts, do you still feel that your truck is missing that little something extra? In this article, we’ll give you a few easy suggestions on how to improve and upgrade your ride with truck performance accessories.

The first thing you need to do is make an honest evaluation of your truck’s current condition. While it may look as new as the day you bought it, could it use a little more “oomph” under the hood? By correctly identifying the areas in which your truck could improve, you will make it easier to find exactly the right upgrade. Let’s take a closer look at a few additions that will turn any truck into a force to be reckoned with.

The first suggestion on upgrading your truck’s performance is to add a high quality exhaust system. An aluminized or stainless steel exhaust will go a long way towards increasing the overall life of your truck. There are several reasons for this, the first being gas mileage. In today’s current market, gas prices are constantly rising, and there is no end in sight. However, you can actually boost your fuel economy by as much as 4 miles per gallon just by adding a new exhaust. That can mean big savings for you over the long haul. In addition, a new quality exhaust system will add some serious power to your vehicle; often times by as much as 10%! Lastly, a new exhaust will give your ride an unmistakable roar that is sure to turn heads everywhere you go. While you can expect to pay several hundred dollars for a top of the line model, it is easy to see that the potential gains far outweigh the cost.

Another upgrade you can make to both look and performance is to improve your truck’s suspension. If you are looking to create an imposing presence with your ride, you may want to consider a suspension lift kit. These kits make it possible to customize your truck with lifts ranging anywhere from 2” all the way up to a monster 8”. The components included in high quality kits all look outstanding, and in addition make it possible to increase tire size and capability. On the flip side, you may want to give your truck that “low-rider” look. This is where a lowering kit with drop shocks can help. Aside from giving your ride a sleek road-hugging look, a lowering kit can also help your truck’s overall performance and handling.

Whether thinking about an exhaust system, a suspension system, or both, you can be confident knowing that you are adding years onto your truck’s life while also making a stylish statement. Best of all – these items can be easily installed by yourself or a professional. Either way, you are sure to love the results when you see what a difference these upgrades truly do make. Enjoy!
