General Challenger

  • 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...
  • 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...
  • All-Wheel Drive

    Four-wheel drive, 4WD, 4x4 ("four by four"), or AWD ("all-wheel drive") is a four-wheeled vehicle with a drivetrain that allows all four wheels to receive torque from the engine simultaneously. While many people associate the term with off-road vehicles and sport utility vehicles, powering all four wheels provides better control in normal road cars on many surfaces, and is an important part in the sport of rallying. The first application of four-wheel drive, occurred in 1893. In 1937, the...
  • Development of Airbags

    Airbags, like lap belts/shoulder belts, are a type of automobile safety restraint system designed to mitigate injury in the event of an accident. These gas-inflated cushions, built into the steering wheel, dashboard, door, roof, and/or seat of your car, use a crash sensor to trigger a rapid expansion of nitrogen gas contained inside a cushion, that pops out on impact to put a protective barrier between passengers and hard surfaces. The National Highway Traffic Safety Administration (NHTSA)...
  1. "Grandfather" of the 2018 Dodge Demon

    Did you know that the controversial Dodge Demon name goes back 48 years? In 1970, the restyled Plymouth Valiant, named the Duster, was a massive success. Dodge immediately insisted on getting its own version. That car became the 1971 Dodge Demon. 1970 Plymouth Duster 340 Both the A-body Plymouth Duster and Dodge Demon were fantastic cars for the money (starting just over $2,100). The two cars were virtually identical, underneath. The attractive-looking Demon came with four optional...
  2. 3.6L Pentastar Engine

    A popular cost-conscious alternative for Challenger owners to the 5.7L and 6.4L Hemi engines is the 3.6L Pentastar engine. It replaced the 3.5L engine, in 2012, and is rated at an impressive 305 horsepower and 270 lb.-ft. of torque, with 90% of its torque available from 1,800 to 6,350 rpm. Performance from this modern 6-cylinder engine actually exceeds some small blocks from the first muscle car era. Before the first aluminum block was cast, the new Pentastar V-6 benefited from more than...

    Active Exhaust

    It’s a fact of life- cars make noise. Inexplicably, there are those in this world who build houses next to major freeways and then complain about the speed of the vehicles going past. There are those who build houses next to airports and complain about the excessive noise. Just as there are those people, there were those who decided that cars were too loud and needed to shut up! This presented car companies with a problem. Their engineers were telling them that for maximum efficiency,...
  4. All About Paint

    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...

  6. Anti-Sway Bars

    An anti-roll bar (roll bar, anti-sway bar, sway bar, or stabilizer bar) is a part of many automobile suspensions that helps reduce body roll during fast cornering or over road irregularities. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness- its resistance to roll in turns, independent of its spring rate in the vertical direction. The first stabilizer bar patent was awarded to Canadian...

    Are Radar Detectors Useless?

    A radar detector is an electronic device that has been used by motorists, for decades, to detect if their speed is being monitored by police using a radar gun. It gave a driver sufficient warning to reduce his speed to avoid being ticketed for speeding. Passport x50 Radar/Laser detector In a general sense, only emitting technologies, like Doppler radar, or LIDAR (pulsed laser light) can be detected. Visual speed estimating techniques, like ANPR or VASCAR cannot be detected in daytime. There...
  8. Camshafts

    Camshafts are used to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve. The cam lobes force the valves open by pressing on the valve, or on some intermediate mechanism, as they rotate. Camshafts can be made out of several types of material. These include: Chilled iron castings: Commonly used in high volume production, chilled iron camshafts have good wear resistance since the...

    Car Salesman Tactics

    When buying a new or used car from a dealership, there are many pitfalls you must avoid. It must be remembered, you and the dealership have different objectives. You are trying to buy your vehicle as cheap as possible and it is trying to maximize its profits. Here are some of the common sales tactics that unscrupulous dealers may use: 1. The Hard Sell Buying a car is a big decision, so never make a purchase simply because you feel pressure from an overaggressive salesman. 2. Selling on...

  11. Crankshafts

    In simple terms, a crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached. It is a mechanical part able to perform a conversion between reciprocating motion and rotational motion. In a reciprocating engine, it translates reciprocationg motion of the piston into rotational motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or "crankpins"- additional...
  12. Crash Test Dummies

    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....

  14. Development & Evolution of the Hemi Engine

    Three generations of Hemi engines have been built by Chrysler for automobiles: the first (known as the Chrysler FirePower) from 1951 to 1958, the second from 1964 to 1971, and the third beginning in 2003. Although Chrysler is most identified with the use of "Hemi" as a marketing term, many other auto manufacturers have incorporated similar designs. The Hemi engine is named for its hemispherical cylinder head. It provides an efficient combustion chamber with an excellent surface-to-volume...
