Chrysler's L platform was used in a family of compact automobiles produced from 1978 to 1990. Loosely based on the Simca 1100 platform developed with Chrysler backing in Europe in the 1960s, the Chrysler L-body was the first domestically made car with transverse front wheel drive using a unibody chassis. It was created in response to the energy crisis of the 1970s and the desire to save internal costs by consolidating Chrysler's American and European operations. It was sold in North America in several lines of similar Dodge and Plymouth vehicles and discontinued when the Chrysler K platform was more successful.
