The model name Challenger refers to a Dodge muscle car that has experienced several distinct generations of production. The first ran from 1969 to 1974, the second from 1978 to 1983, and the most recent historically from 2008 onward. The 1969 to 1974 generation was Dodge's first riff on the "Pony" car craze initially sparked by the introduction of the 1964 Ford Mustang.
The first car dubbed the Challenger was actually introduced by Dodge in 1959 as a limited edition sedan version of their Coronet, and was a two-door model exclusively finished with silver paint. However, by the late 1960's, Dodge found itself in need of a response to the Ford Mustang and Chevy Camaro, and released the Challenger using many of the same components featured in other Chrysler E Platform vehicles, such as the Plymouth Barracuda. The second generation Challenger's design and engineering were derived principally from the Mitsubishi Galant Lambda.
The 2008 third generation Challenger was again a response to developments among competitors, particularly to fifth generation Mustangs and Camaros that were enjoying a resurgent popularity. This newest Challenger was a two-door coupe that featured four, five and eight speed automatic transmissions and a six speed manual. One of the largest engines offered is a 392 cubic inch, 6.4 liter Hemi V8, which has been available since 2011. The 2015 model boasts the size engine, bolstered by 485 horsepower and 475 foot pounds of torque.
