The "SXT" designation on a car refers to a particular trim package included with the vehicle. Dodge is the only car manufacturer to use the "SXT" designation. It is an acronym for "standard extra," referring to the standard options plus extras.
Dodge car models that offer the SXT trim package include the Avenger, the Challenger, the Charger and the Dart. The SXT trim package is also available on the Durango SUV, the Journey crossover vehicle and the Grand Caravan minivan. The amenities included in the SXT package vary with the model of the vehicle. Some models also offer an SXT Plus package with luxury amenities, such as leather interiors.
