The Escalade is a large sport utility vehicle (or SUV) sold by the General Motors luxury brand, Cadillac. It was the division's first major entry into the popular SUV market. The Escalade was introduced for the 1999 model year in response to German and Japanese competitors and to Ford's 1998 release of the Lincoln Navigator. The Escalade project went into production only 10 months after it was approved.
