The 300 is a full-size sport/luxury sedan and wagon which was first shown at the 2003 New York Auto Show as a concept car and first introduced in the spring of 2004 as an early 2005 model.
The new 300 was built to bring a high performance, sporty sedan to compete with the likes of the Buick LaCrosse and the Mercury Montego (launched at the same time as the 300). Unlike the LaCrosse and Montego, the 300C is rear wheel drive and offers comparable luxury at a lower price. The 300 is also sold in Europe as both a sedan and a station wagon. The station wagon, sold in Europe as the 300 Touring (not to be confused with the North American sedan's "Touring" trim level), shares its body pieces of the C-pillar with the Dodge Magnum. The 300 Touring differs from the Magnum in that its exterior stying and interior fitment are that of the 300/300C instead of the less-luxurious Magnum.
Chrysler introduced a special SRT-8 version of the car at the Pebble Beach Concours d'Elegance in 2004. It includes a new 6.1 L Hemi which produces 425 hp (317 kW). It went on sale in February of 2005 and has a sticker price of US$42,695 as of 2006 plus the gas guzzler tax.
