Platform Heritage

The Hyundai Santa Fe (Korean: 현대 싼타페) is a series of crossover SUVs produced across five generations by the South Korean manufacturer Hyundai since 2000. It is named after the city of Santa Fe, New Mexico, and was introduced for the 2001 model year as Hyundai's first SUV. The Santa Fe was a milestone in the company's restructuring program of the late 1990s because the SUV was a hit with American buyers. The Santa Fe was initially marketed as a compact crossover SUV in its first-generation. After the Tucson was introduced in 2004, marketed under that same class, the Santa Fe was later repositioned into the mid-size crossover SUV class since its second-generation launched in 2005. Through all generations, the Santa Fe has been offered in either front-wheel drive or all-wheel drive. The third-generation Santa Fe introduced in 2012 was available in two versions, which are regular (short) and extended long-wheelbase version. The short model was sold as the Santa Fe Sport in North America (three-row seating was not available) and simply Santa Fe in global markets (three-row seating was standard or optional), while the extended long-wheelbase model is called the Santa Fe in the U.S., Santa Fe XL in Canada and called the Hyundai Maxcruz in South Korea. The fourth-generation model, which was launched in 2018, introduced hybrid and plug-in hybrid powertrain (since 2020), and the fifth-generation model, which was launched in 2023, discontinued diesel engines.
