Dodge Charger

The Dodge Charger is a brand of automobiles marketed by Dodge. The first Charger was a show car in 1964. There have been several different production Chargers, built on three different platforms and sizes. In the U.S., the Charger nameplate has been used on subcompact hatchbacks, full-sized sedans, and personal luxury coupes. The current version is a four-door sedan.

Charger models

The three main iterations of Dodge Chargers were a mid-size (B-body) two-door car (1966–78), a subcompact (L-body) car (1983–87), and the (LX and LD) full-size platform four-door sedans built since 2006.

The name was also carried by a 1999 concept car that differed substantially from the Charger eventually placed into production for the 2006 model year. A similar name plate, the Ramcharger, was used for the truck-based vehicle.

The name Charger was also used in Brazil as performance model based on the Dart (A-Body) (1970–80).

Dodge

Dodge is an American brand of cars, minivans, and sport utility vehicles manufactured by FCA US LLC (formerly known as Chrysler Group LLC), based in Auburn Hills, Michigan. Dodge vehicles presently include the lower-priced badge variants of Chrysler-badged vehicles as well as performance cars, though for much of its existence Dodge was Chrysler's mid-priced brand above Plymouth.

Founded as the Dodge Brothers Company by brothers Horace Elgin Dodge and John Francis Dodge in 1900, Dodge was originally a supplier of parts and assemblies for Detroit-based automakers and began building complete automobiles in 1915, predating the founding of Chrysler Corporation. The Dodge brothers died suddenly in 1920 and the company was sold to Dillon, Read & Co. in 1925 before being sold to Chrysler in 1928. Dodge vehicles mainly consisted of trucks and full-sized passenger cars through the 1970s, though it did make some inroads into the compact car market during this time.

Due to various market conditions, Dodge's first financial crisis, as a division of Chrysler, was averted in 1955, when Prudential gave them US$250 million; combined with the all new styling approach ushered in by Virgil Exner, Chrysler recovered and sales increased.

Jeep Grand Cherokee

The Jeep Grand Cherokee is a mid-size SUV produced by the American manufacturer Jeep. While some other SUVs were manufactured with body-on-frame construction, the Jeep Grand Cherokee has always used a unibody chassis.

Development

The Grand Cherokee's origins date back to 1983 when American Motors Corporation (AMC) was designing a successor to the smaller Jeep Cherokee (XJ). Three outside (non-AMC) designers—Larry Shinoda, Alain Clenet, and Giorgetto Giugiaro—were also under contract with AMC to create and build a clay model of the Cherokee XJ replacement, then known as the "XJC" project. However, the basic design for the Cherokee's replacement was well under way by AMC's in-house designers and the 1989 Jeep Concept 1 show car foretold the basic design.

As AMC began development of the next Jeep in 1985, management created a business process that is now known as product lifecycle management (PLM). According to François Castaing, Vice President for Product Engineering and Development, the smallest U.S. automaker was looking for a way to speed up its product development process to compete better against its larger competitors. The XJC's development was aided by computer-aided design (CAD) software systems making the engineers more productive while new communication systems allowed potential conflicts to be resolved faster, thus reducing costly engineering changes because all drawings and documents were in a central database. The system was so effective that after Chrysler purchased AMC in 1987, it expanded the system throughout its enterprise, thus connecting everyone involved in designing and building products.

Drag racing

Drag racing is a type of motor racing in which automobiles or motorcycles (usually specially prepared for the purpose) compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly ¼ mile (1,320 ft (402 m)), with a shorter 3/16 mile 10 feet (1,000 ft (305 m)) used by nitromethane powered Top Fuel dragsters and funny cars along with some bracket races, while 660 ft (201 m) (1/8 mi) is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

Drag racing has existed in both street racing and regulated motorsport forms since automobiles and motorcycles were developed. The street racing form, which is usually illegal, is covered elsewhere; this article covers the legal sport.

Basics of drag racing

Before each race (commonly known as a pass), each driver is allowed to perform a burnout, which heats the driving tires and lays rubber down at the beginning of the track, improving traction. Each driver then lines up (or stages) at the starting line.
