  • What is a CVT Transmission?

    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...

  1. The Origin of Scat Pack

    The Dodge Scat Pack was originally introduced in 1968 with the Charger R/T, Coronet R/T, Dart GTS, and Super Bee. In 1969, the Charger Daytona joined the Pack. In order for a car to enter the Scat Pack it had to be capable of running the quarter mile in the 14s (14.99 sec. or faster). Mainly a marketing term, Scat Pack cars got twin bumblebee stripes and special decals. It became legendary in the enthusiast community and symbolized one of the most feared groups of street machines every to...
  2. Challenger- Concept to Production

    The planning and design of the Challenger concept car started in 2004. At that time, Chrysler’s Pacifica Studo was given the assignment to work with the exiting LX platform (i.e., Charger, Chrysler 300 and Magnum) to develop a 2-door, rear-wheel drive concept car. Many of the designers were musclecar guys and a new Challenger was proposed to be built around the 6.1 Hemi engine. There was a lot of conversation as to how much retro design features should be built into the car. Based on a...
  3. Evolution of Hood Scoops

    Back in middle school science class, we learned that in order to make fire, you need three ingredients: fuel, ignition and air- or, more specifically, oxygen. You’ll also remember that cold air is denser than hot air, putting more oxygen in the same amount of volume. While the modern internal combustion engine does a fine job of delivering fuel and ignition, that cold air part becomes tricky as you try to route fresh air from outside through a hot engine compartment. In response, in the late...

    100th Article! Dodge Brothers

    Few people are aware of the important role that John and Horace Dodge played in shaping Detroit’s early auto industry, and of the story of a dynamic partnership formed between two enterprising brothers who remained inseparable throughout their lives. John (right) and Horace Dodge HUMBLE BEGINNINGS Born into an industrious but poor family, Dodge brothers, John (born in 1864) and Horace (born in 1868), received their mechanical training from working in their father’s machine shop, in Niles,...
  5. Auto-Stop/Start Technology

    Since the Obama Administration finalized standards in 2012, to encourage the automotive industry to reach a 54.5 miles per gallon corporate fuel economy average by 2025, manufacturers have been employing every means possible to squeeze another mile out of a gallon of gasoline. A combination of aerodynamics, weight savings, electrification, hybrid technologies and advanced engine management software has gone a long way, but it doesn’t take a rocket scientist to understand that you save a lot...
  6. Car Weight Terminology

    There are three different terms that are used concerning a car's weight- Gross Vehicle Weight Rating (GVWR), Gross Vehicle Weight (GVW) and Curb Weight. So how are they different? A car’s Gross Vehicle Weight Rating (GVWR) refers to the maximum poundage your car can weigh to operate safely and without harm to its components. Put simply, it's the maximum weight before everything breaks. Manufacturers calculate this number by testing the structural integrity of your car’s suspension...
  7. Why Do Hemi Engines Have Dual Sparkplugs?

    Each cylinder on a Hemi engine has an ignition coil pack over one spark plug, and a regular plug wire connected to the other spark plug. Further, the coil pack also has a plug wire attached to it that extends to the opposite cylinder bank. Each cylinder shares a coil pack with another cylinder. Each of the two plugs on a given cylinder is fired by a separate coil. One plug has a coil directly attached, and the other is fired via an ignition wire connected to a coil located on another...
  8. High Impact Paint

    In the late 60s/early 70s, Dodge was already offering some of the hottest cars of the muscle car era- awesome machines like the Hemi Challenger and 440 Six-Pack Super Bee. Designers, however, decided to rev up the cars’ visuals to match, creating a far-out assortment of vibrant exterior paint colors. These special colors (a $15 option) generated a big buzz in the showrooms and launched an industry trend. The color palettes used by all the automakers were opened up, giving paint designers...
  9. History of the Dodge Logo

    Dodge was founded in 1900 by Horace and John Dodge (The Dodge Brothers). It was initially known as the Dodge Brothers Company and used to sell bicycles, but then within two years it became a major supplier of axles, engines, and transmissions to the automobile industry. The company started by producing chassis and engines for the Ford Motor Company and Olds Motor Vehicle Company. However, with the stress and demands of the booming automobile industry, the brothers decided to tinker with the...
  10. Superchargers vs. Turbochargers

    When designing an engine to pull in more than atmospheric pressure, engineers often turn to forced induction. It’s one of the fastest ways to add significant power to almost any engine, and there are two prevalent ways it can be done: supercharging and turbocharging. But, which is better? Both are different in terms of how they work, performance and cost. Both operate on the principle that the more air you can get into your engine, the more power your car will make. Supercharging is old...
  11. World's Fastest Hellcat

    When Dodge introduced the Challenger Hellcat back in 2014, it claimed that in stock form with the automatic transmission, it could cover the quarter mile in just 11.2 seconds. With drag radial tires, the time could be reduced down to the 10.80s The first Hellcat owner to break into the 10-second range was Jay Gustafson, who ran a 10.997 a few years back, making his Challenger the quickest stock Hellcat car in the world, but Canadian racer Jim Benko recently ran a 10.937, on November 11,...
  12. The Meaning of "Mopar"

    Short for the Chrysler Motor Parts Corporation, Mopar made its first appearance in the late 1920s and became its own brand in 1937. The name Mopar was created by a committee to market cans of "Chrysler Motor Parts" antifreeze. From there, the Mopar catalog expanded to include waxes, cleaners, filters, engine parts and more. Now, in its 81st year, Mopar encompasses the full line of Fiat Chrysler Automobiles parts, accessories, and customer service, including Fiat and Alfa Romeo brands...
  13. Ralph Gilles- A Real Mopar Guy

    Mopar enthusiasts owe the fantastic array of performance models to Ralph Gilles, Head of Design for Fiat Chrysler Automobiles. We are truly fortunate to have a cool car guy in charge. Gilles, as a boy living in Quebec, was drawing concept vehicles at the age of eight. When he was fourteen years old, his aunt sent one of his sketches to Chrysler Chairman Lee Iacocca. A reply came from K. Neil Walling, Chrysler's design chief at the time, suggesting he attend one of three design schools....
  14. Evolution of Rear Spoilers

    A car spoiler is a stylish automobile accessory that can be mounted on the rear of most cars. There are many different styles of spoilers. The general shape consists of a slender slightly downward angled piece of metal, fiberglass, silicone or carbon fiber that is usually the width of the vehicle. Some seem to appear to mold into the vehicle and others stick out with two small ledges on both sides. The term "spoiler" is often mistakenly used interchangeably with "wing." An automotive wing...
  15. Evolution of Racing Stripes

    Racing stripes are usually a “must have” for owners of muscle cars. These stripes, originally called “go faster stripes,” first appeared on Cunningham race cars in 1951. Two parallel blue stripes ran from front to rear in the center of the white car body. Their main purpose was to help spectators identify the cars during races. They evolved from the traditional FIA registered U.S. Racing color of a white body and blue chassis, which dated from when racing cars had the chassis exposed. The...
