The Dodge Magnum name has been used on a number of different Dodge-brand automobiles. The most recent is a large rear wheel drive station wagon introduced in 2004. This new Magnum is Dodge's first car to use the new Chrysler LX platform, shared with the Chrysler 300 and the forthcoming Dodge Charger. Previously, the Dodge Magnum model name had been used from 1978 to 1979 for a large sedan in the United States. In Brazil, the Magnum name was a version of their Plymouth Valiant from 1979 to 1981. In Mexico, the Magnum was a K car from 1983 to 1990.

1978

The 1978 Dodge Magnum in the United States was a rebadged Chrysler Cordoba. Although this Magnum did not sell well, it symbolizes the end of an era when Chrysler was famous for large powerful rear wheel drive cars; a connotation that Chrysler seem to be capitalizing on with the new 2004 Magnum.

Brazil

In Brazil, the Plymouth Valiant/Dodge Dart continued in production until 1981. For the last three years, a 2-door version was sold as the Magnum, while the 4-door was the Chrysler Le Baron , Dodge Dart, and Dodge Charger RT.

Mexico

The same Brazilian Valiant derivative was sold in Mexico. But 1983 saw the introduction of the K car Magnum. This version stayed in production until 1990.

2005

The Magnum name was revived in 2004 as a 2005 station wagon on Chrysler's LX platform.

The new Magnum has three engine options, the SE features the 190 hp 2.7 L LH V6, the SXT has the 270 hp 3.5 L V6, and the RT has the new 5.7 L Hemi V8.

The Magnum will also be available with all wheel drive in 2005 on SXT and RT models. The AWD SXT and the RT use a Mercedes-Benz-derived 5-speed automatic transmission, while all other models use a four-speed automatic.

Like the Chrysler 300, the new Magnum has been a stunning success for the company, easily outselling its predecessor, the Dodge Intrepid. Dodge has announced plans for the Magnum to go on sale as a police variant to compete against the Ford Crown Victoria. Available only to law enforcement, emergency agencies, and government agencies, the vehicle will have the SXT's V-6 as a base motor and the Hemi as an option, along with police-specific options such as a steering-column mounted shifter, deactivated interior rear windows and locks, and bulletproof glass between the first and second rows of seats and the cargo area.

The Magnum was on Car and Driver's Ten Best list for 2005.

SRT-8

For 2005, an SRT-8 version will be produced. Like the 300C SRT-8, it will feature the new 6.1 L Hemi engine, which produces 425 hp (317 kW). 20 in wheels, new lower-body treatment, and a revised front- and rear-fascia completes the transformation. The SRT-8 debuted at the 2005 Los Angeles Auto Show.
