From model years 1970 to 1974, the first-generation Dodge Challenger pony car was built using the Chrysler E platform in hardtop and convertible body styles sharing significant components with the Plymouth Barracuda.

[1] The second generation, from model years 1978 to 1983, was a badge engineered Mitsubishi Galant Lambda / Sapporo,[2] a coupe version of an economical compact car.

[5] The E-body Challenger was introduced in the autumn of 1969 for the 1970 model year,[6] similar in appearance to but somewhat larger than its platform-sharing Plymouth sibling, the Barracuda.

It was positioned to compete against the Mercury Cougar and Pontiac Firebird in the upper end of the pony car market segment[7] that the Ford Mustang had pioneered in April 1964.

[12] With 1971 being the sole exception, the front ends of both cars differed from each other in that the Challenger had four headlights and the Barracuda had only two; a trend replicated by offerings from Chrysler's rivals.

Cameron based the 1970 Challenger grille on an older sketch of a stillborn 1966 Charger prototype that was to have a turbine engine.

J. J. Yeley indicated his two-car team would continue to field a Challenger in the series for as long as he can find parts to keep the cars running.

Powered by a Hemi 392 slightly modified for road racing extremes and restricted by class rules, the cars made around 500 horsepower.

Joe Stevens also received the Cool Shirt Hard Charger award for his excellent rookie season performance.

On August 15, 2022, Stellantis formally announced that Dodge Challenger, Charger, and Chrysler 300 production would end following the 2023 model year, stating tightening U.S. EPA emissions requirements as reasons for doing so.

[20] In response, the company announced a series of "Last-Call" models with special paint and unique trims to commemorate the Challenger and Charger.

The final Dodge Challenger, a Pitch-Black Demon 170, rolled off the Brampton assembly line on December 22, 2023; it was also the very last vehicle built on a derivative of the long-running Chrysler LX Platform, which was introduced in 2004 for the 2005 model year.

An internal combustion version is rumored to be offered as well, utilizing the twin-turbocharged 3.0L Hurricane inline-6 engine, shared with the Jeep Wagoneer/Grand Wagoneer and 2025 Ram 1500; it is set to be paired to an eight-speed automatic transmission.
