General Challenger

  • 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...
  • Crumple Zones

    Crumple zones, crush zones, or crash zones, are a structural safety feature used in automobiles, to absorb the kinetic energy from the impact during a collision by controlled deformation. This energy is much greater than is commonly realized. A 4,409 lb. car traveling at 37 mph.,before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 47 ft. crashing on to a solid concrete surface. Increasing that speed by 50% to 56 mph. compares...
  • 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...
  • 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 order for a car to enter the Scat Pack it had to be capable of running the quarter mile in the 14s (14.99 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 rumble from stoplight to stoplight. In the early...
  • How Do Navigation Systems Work?

    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...

  2. Forged vs. Cast Wheels

    When choosing aftermarket wheels for your Challenger, there is a considerable amount of choice. Car wheel technology has evolved considerably, over the years, from steel- once the preferred material- to lighter weight aluminum alloys. Among all types, you have the option of choosing between forged and cast wheels. In discussing the difference between the two, it is important to distinguish between the advantages and disadvantages of forging and casting. The strength of any metallic product...
  3. 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...
  4. 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...

  6. Hood Pins

    Hood pins are used as a secondary restraint for the hood and are attached by a pin and plate drilled through the hood. They were originally made for the racetrack to keep hoods buttoned down at high speeds, but found their way onto muscle cars of the late 60s/early 70s. Hood pins (two per hood) were most prevalent on Dodge and Plymouth muscle cars of that era (e.g., Challengers, ‘Cudas, Road Runners, Daytonas, GTXs, Super Bees, etc.). They were, primarily, a styling element used to give a...
  7. 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...
  8. 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....
  9. 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...
  10. 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,...
  11. Ronnie Sox- A Tribute to "Mr. Four Speed"

    Ronnie Sox is one of the greatest Mopar drag racers. Like many who eventually became professional racers, "The Boss," grew up around cars, raised in the shadow of his family’s Sinclair service station. As soon as he was old enough to drive, Sox began competing in drag races, sponsored by the Police Club of Burlington, NC, at a local airport. In the early days, Sox didn’t even own a car and used his father’s 1949 Olds. From these humble beginnings, Sox would go on to become what many...
  12. Slicks & Drag Radials

    Drag radial street-legal tires had their origin in racing. Originally, race cars used “racing slicks”- a type of tire with a smooth tread. The first production "slicks” were developed by M&H Tires in the early 1950s for use in contact patch to the track and maximized traction for any given tire dimension. Slicks were also used on road and oval track racing where steering and braking require maximum traction from each wheel. Slicks, however, are not suitable for use on street cars which...
  13. 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...
  14. 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...
  15. History of SRT

    Performance vehicles are a Chrysler tradition. In the 1950s, an elite team of Chrysler engineers set out to extract extreme horsepower from existing engines. The team created new manifolds featuring long-tube intake runners. The innovative design helped engines ingest more air, translating into improved performance. The new induction system was called “Ramcharger,” and the team behind the technology adopted that name. The Ramchargers’ new engine produced enormous amounts of power,...
