In the early days of the automobile industry, painting was a slow process. It was applied manually and dried for weeks at room temperature by solvent evaporation. 1930 Packard Factory As mass production of cars made the process untenable, paint began to be dried in ovens. Nowadays, two-component (catalyzed) paint is usually applied by robotic arms and cures in just a few hours either at room temperature or in heated booths. (Note- That is why car paint can be waxed as soon as the new owner...

A limited-slip differential (LSD), or “anti-spin” differential is a type of differential that allows the rear wheels on a vehicle to turn at different speeds when executing a turn. They are widely used in high performance and four-wheel-drive vehicles because they provide superior traction abilities. Various types of differentials can be classified as "anti-spin." These include limited slip, locking and spool differentials. Each performs differently on and off the road. Generally, only...

Carbon Fiber is a polymer and is sometimes known as graphite fiber. It is a very strong material that is also very lightweight. Although carbon fiber is five times stronger and twice as stiff as steel, it is lighter than steel; making it the ideal manufacturing material for many parts. These are just a few reasons why carbon fiber is favored by engineers and designers for manufacturing. Carbon fiber dates back to 1879, when Thomas Edison baked cotton threads or bamboo silvers at high...

The NHRA has a huge variety of categories and eliminators. Class eligibility is based on requirements that include type of vehicle, engine size, vehicle weight, allowable modifications and aerodynamics. Top Fuel, Funny Car, Pro Stock, Top Alcohol Dragster, Top Alcohol Funny Car, Super Comp, Super Gas, Super Street and Pro Mod feature a single class of vehicle in heads-up competition. Comp, Super Stock, and Stock are made up of a variety of classes equalized by a handicap starting system....

Not sure how this will work, but is a great article [URL]https://thecaraficionada.com/history-chryslers-hemi-engine/[/URL]

A new car dealer has a 2017 Mopar edition that was never sold. Less than 50 miles. Sticker was 63,000 reduced to 50,000. Question I have what is the better choice. A 392 scat pack or the Mopar edition? Seems the Mopar edition is around Hellcat price. I have a 14 Mopar edition, don't see many for sale. Depends on what I can get. Thanks

Getting lost while driving, or stopping at a gas station to ask for directions, has become a thing of the past. With GPS in your car’s navigation system, in the portable navigation device on your dashboard, or in your smartphone, it is easy to pull up a map and see where you are, or get directions to where you are going. GPS makes you safer, routes you around traffic delays and helps you find nearby services. GPS (Global Positioning System), a technology we now take for granted, started...

Over the past 97 years, “entertainment systems” in cars have evolved from primitive 6-volt dry-cell AM radios to high-tech Bluetooth units. It is interesting to take a look back to see how technology has changed over the years. Here is a brief, illustrated chronology of these devices: 1922: First radio in a Car The first radio (“Marconiphone”) appeared in a Daimler car at the Olympia Motorshow in England. 1927: First Radio in Mass-Produced Car The “Transitone” radio appeared in a...

The term hydroplaning is commonly used to refer to the skidding or sliding of a car’s tires across a wet surface. Hydroplaning occurs when a tire encounters more water than it can scatter. Water pressure in the front of the wheel pushes water under the tire, and the tire is then separated from the road surface by a thin film of water and loses traction. The result is loss of steering, braking and power control. Rubber tires have tread (grooves) that are designed to channel water from...

Fuel economy for vehicles (city, highway and combined) is measured under controlled conditions in a laboratory using a series of tests specified by federal law.The results are displayed for the consumer on the "new car window sticker." Estimating MPG with Laboratory Tests In the laboratory, the vehicle's drive wheels are placed on a machine called a dynamometer. The "dyno" simulates the driving environment much like an exercise bike simulates cycling. Engineers adjust the amount of energy...

Tire speed ratings first originated in Europe in the 1960s, as a way to make sure increasingly faster vehicles were equipped with appropriate safe tires. These early speed ratings set the foundation for the current speed rating system used by the DOT and tire manufacturers. Every tire approved for highway use by the Department of Transportation comes with a particular speed rating. The speed rating is a letter corresponding to the maximum safe speed at which a tire can be driven, as...

A crash test dummy is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers,automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data, such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision....

Pro Stock quarter mile drag racing times have dramatically decreased over the decades, since the class was established in 1970. This has been the result of tremendous advances in technology. To determine who is the fastest competitor, forty-nine years ago, NHRA instituted the Mello Yello Drag Racing Series. The champion is determined by a point system where points are given according to finishing placement and qualifying effort. The season is divided into two segments. After the first 18...

Some say you can't teach an old dog new tricks. But the innovative continuously variable transmission (CVT), which Leonardo da Vinci conceptualized more than 500 years ago is now replacing planetary automatic transmissions in some automobiles. Since the first Toroidal CVT patent was filed in 1886, the technology has been refined and improved. Today, several car manufacturers, including General Motors, Audi, Honda, Hyundai and Nissan, are designing their drivetrains around CVTs. Cars with...

Still not quite sure how to post an article yet, but Finally: Why manual transmission is better than an automatic [URL]https://tremec-blog.com/10-reasons-a-manual-transmission-is-better-than-an-automatic/[/URL] Not so long ago, it was widely accepted that a true performance car had a manual transmission. In fact, some performance cars were only available with a manual transmission. Well, in the great age that is the 21st century, things have changed. Now the beloved third pedal is being replaced with...
