Important Things Should I Know About Jumper Cables

Isn’t it the worst feeling ever when your car will not start when you need it most? What if your car broke and you are running late for a meeting? Even worse, what if you do not have jumper cables to restart the car and get you back on the road?

This is the situation that many drivers try to avoid as much as possible. What all of us just want is for vehicles to work and get us from Point A to Point B consistently every day.

Without a jumper cable, these situations will leave any driver very helpless and hopeless.

World’s Worst Car Models Ever Made

Every year, different brands of car are being manufactured from different countries all over the world. Some are great and some are good, but others are just terribly bad. The quality and design are just so bad, that it makes you wonder who in the world would actually purchase such junk. That may be too harsh, but others just think of that way. After all, cars are never inexpensive. Not to mention the cost of the change oil, regular inspection, and the overall maintenance. It’s natural for people to find a car that will pay back its expensive worth.

Check out these worst cars that were ever made in the world. Who knows one of the models are similar to yours.

1982 Cadillac Cimarron

Let’s face it: not all American auto manufacturers are very good at designing car models. You can’t argue about this, especially when the 1982 Cadillac Cimarron tells you that. Sure thing, Cadillac is considered as the best car models that were ever made in America and probably even around the world. This one is just the only exception. It was designed with just a little bit nicer clothing than a Chevrolet Cavalier, but other than that, 1982 Cadillac Cimarron had nothing else to brag about. It never sold well in America. Today, it’s probably rotten in a parking garage somewhere, isolated from the sight of the world.

1955 Dodge La Femme

By the name itself, you probably already got the idea that this car was built for women as if they can’t drive the ones built for men. The 1955 Dodge La Femme, from the perspective of some if not all, it has a very girly design. It is painted in pink and white on the outside. The silly pink theme doesn’t end there. On the inside, you can see the world of pink. The seats, rain cape, umbrella, and many others are all in pink color. Plus, a purse for feminine needs! This car is probably a good news for many women in its time, but unfortunately, in didn’t sell well. It was only sold for two years before it disappeared in the market. Maybe because the model was more about the physical feature and less in the engineering matters.

1974 Mustang II

Mustang is a good car brand, but not until 1974 Mustang II was released. Ever since Mustang II appeared in the world, Mustang brand has had a bad record. Mustang II has given owners a serious trouble. It was redesigned for some reasons (one of the reasons may be because of the complaints of buyers), introducing the new Pinto. Many people have been driven to confusion of this release, though. It was redesigned, but it still gave people pain in the head. It’s got a rear-end gas tank, which, some says, could explode every time you run out of rear-end gas. Its machine power and muscle are poor, because of the oil embargo effect. Pretty troublesome, isn’t it?

1958 Edsel Corsair

Edsel has quiet a lot of fans. They fancied Edsel, but for some reason, the love they had for Edsel cars faded. 1958 Edsel Corsair is probably the most responsible for this change of heart. People has once hailed Edsel as a savior to Cold War, but when the car’s front end came, the name Edsel almost instantly became the definition of disaster. It’s funny and painful at the same time how Ford’s $300 million has gone to waste. The car’s steering wheel has push buttons, which has become one of the major causes of accidental gear-shifting while honking the horn.

2003 Saturn Ion

It’s really funny how, even in the 2000s, there are still cars that just don’t deserve to be called as a vehicle. Saturn tried to make a real car in 2003 and unsurprisingly, failed. Who would even call a plastic-made car a vehicle? Some may probably consider if it was a high-quality kind of plastic, but sadly, the plastic used was cheap. The poor quality plastic was just practically wrapped around the exterior of the car. Even when you focus away from the physical features, there’s still nothing good about 2003 Saturn Ion. Don’t even try to ride it for a meter. You’ll probably have the worst driving experience in your life.

1981 DeLorean DMC-12

John Z. DeLorean was a notorious auto designer, for a bad reason. His creation – 1981 DeLorean DMC-12 – made his name hot around the world. The gull-wing doors of the car can’t be opened without power, resulting in more than a lot of drivers getting locked inside every single time there’s an electrical failure. The acceleration of the car was as slow as an old lady, really. And when it rains, there has always been water leak on the inside. A lot of people was actually amazed of the car’s price. This is probably the reason why it sold more than other car models on this list. After a few drive, though, buyers had their regrets.

DeLorean added more bad records to his name. He involved himself in a money-laundering scheme and eventually got caught out of his actions.

1957 Trabant P50

You probably already know that this is another terrible car, but you might want to hear the story behind its creation first. Trabant was built in East Germany by unmotivated, underfunded workforce. Because of this very reason, the car was made out of Duroplast, a cheap plastic made out of wood and cotton fiber. Its engine only had 18 horsepower. It would probably barely run with such low power. It also required mixture of oil and gas, which results to black smoke as it runs. The gear system was the worst, some says.

1987 Yugo GV

This car was shipped to Siberia, redesigned for a make-over, and was sold for the lowest price possible. It was fair enough for Yugo manufacturers, at least, to know how low the quality of their car is and think of the budget of their buyers. Yugo GV really deserves to have the initial of “Good Value“, although it always breaks down and often doesn’t work.

How Torque Contributes To The Overall Car Performance

Torque is a very common term that a lot of people might read when they go to car websites or check out car magazines. You may also hear the term very often when you pay a visit to your mechanic. However, most people do not actually know what torque is and how the torque contributes to the overall performance of the car. I’ll be explaining what exactly torque is and how crucial the torque is to the car.

Understanding What Torque Is

Before we go on to discussing how torque contributes to a car’s performance, we first have to understand what exactly torque is. In a nutshell, the term “torque” is actually a term in physics which relates to rotational power. Torque is the rate of turning power produced by an object that has the tendency to rotate around an axis or, as physicists would say, a fulcrum. In mathematical terms, the torque is equal to the change in angular momentum. The amount of torque that a lever would produce is directly related to the distance of the fulcrum from the fulcrum to the end of the lever. This means that the longer the lever, the more torque is produced because of the ease of ability to rotate.

Applying Torque Concepts in Machines

In machines like cars, the torque is usually found inside the engine. If you want to measure how much power a machine makes, then you have to measure the amount of torque that an engine creates. This is the rotational power that the axis makes the parts produce so as to power up the engine to make the machine work. Basically, you can tell if a car is powerful by knowing how much torque its engine produces. If the figures are leaning toward a high side, then the car is very powerful. However, if the figures are leaning to a rather low side, then the car’s engine isn’t that powerful.

The Torque’s Significance to A Car

Now that we know what torque is, the main question now is what is the significance of the torque to the car? Well, we do know that torque is the power generated from rotational movement inside the engine. We also know that the engine is used to speed up the car. So with these facts on hand, we know that the torque is very important for a car to accelerate. If you are a driver, then you know how important it is for a car to accelerate easily. If the car is able to accelerate with ease, then the engine is producing a high rate of torque. The torque produced by the internal-combustion engine is the one that will make all the other parts of the car spin in accordance. The torque from the engine then gets transmitted to the tires which will make the tires spin. With this, we can really see how the torque can make a car accelerate.

Torque in the Wheels

In my previous point, I discussed torque in the engine. Now, I’m going to concentrate on torque in the wheels. As I have said above, the torque from the engine gets transferred to the wheels. However, the wheels have their own torque generated as the wheels run on an axis which is found in the center of the tire. This is where the gears come in. The gears will control the torque that is provided to the tires depending on how fast or how slow you are driving. If you are slowing down, then less torque will be forced upon the wheels. If you are going faster, then more torque will be given. This is why there are 4 different gears (5 for sports cars). The 4 gears will help you control torque so that not too much is applied when you are going slow and not too little is applied when you are going too fast. Notice that if you are using the wrong gear, your car makes funny noises. This is because the wrong amount of torque is being forced upon by the car. Of course, if you use an automatic transmission car, then the gears will automatically shift by themselves.

Torque in relation to Horsepower

Most people often use horsepower to measure how powerful a car is. What most people are not aware of is that the torque should be the main measurement of a car’s power because the torque is what can actually produce horsepower. So let’s discuss how horsepower and torque are related to each other.

In order to know the relation between the two, it is essential that you know about both. Since I’ve already explained how torque works in my points above, now I’ll talk about horsepower. Horsepower is, in a nutshell, the amount of work produced over a certain time period. Horsepower is very different from torque because torque produces acceleration while horsepower is more related to the overall speed at a given time.

Now that we know about horsepower, let’s put the two together. As I stated earlier, it is actually the torque that produces horsepower. We can see how this works if we examine the formula for horsepower. Horsepower is equal to torque multiplied by RPMs or revolutions per minute divided by 5252. 5252 is constant so this will always be part of the formula. If you turn it into its mathematical form, it will look like this:

Horsepower = (Torque) (RPM) / 5252

Now, one thing to remember is that without torque, there is no horsepower. You need to accelerate the car before you reach a constant speed while you are driving on the road. The torque will be the factor that produces units of acceleration while the horsepower is the one that produces the speed. In essence, the torque will measure the car’s power. Using this logic, we can actually say that the torque contributes to the overall speed and power of the car and not just the acceleration. Although the torque produces the acceleration, the acceleration is needed to produce speed so the torque indirectly also contributes to producing overall speed.

Conclusion

Torque in general is very crucial to the performance of a car. First of all, torque generates acceleration. If you want your car to go fast, then your engine must be able to generate a high torque. This, in turn, would make your tires move due to the overall rotational movements of the parts inside the car. Not only does torque produce acceleration but it also produces horsepower. As the formula states, you need torque in order to produce horsepower. Although torque does not directly produce horsepower, it is a component (along with revolutions per minute) in the production of horsepower.

Since the torque produces acceleration, speed, and movement for the tires, then we can say that the torque heavily contributes to the performance of a car. If you are a race car driver, for example, you need an engine that can produce a high torque so that you can accelerate quickly and maintain your speed. You also need that torque to get your tires moving right away.

In conclusion to that, if you want to really measure the power of your car, I’d say that you should take a look at how much torque the engine produces.
