 It is named after the city of Santa Fe, New Mexico, and was introduced for the 2001 model year as Hyundai's first SUV, released at the same time as the Ford Escape and Pontiac Aztek.
 The Santa Fe was a milestone in the company's restructuring program of the late 1990s because, despite receiving criticism from journalists for its obscure looks, the SUV was a hit with American buyers.

 As of 2007, the Santa Fe falls between the slightly smaller compact crossover Tucson and the larger, yet related luxury crossover SUV Veracruz (which replaced the Terracan).
