Powerful and unapologetically American, the Cadillac Escalade ESV is the Big Kahuna of the Escalade luxury SUV family. Everything about it is massive, from its extended wheelbase to its V8 engine and Bose sound system. Introduced in 2003 as a variant of the regular Escalade, the ESV broadens the Escalade's appeal by offering the absolute maximum in passenger room and cargo space.
