Platform Heritage

The Kia Sportage (Korean: 기아 스포티지) is a series of automobiles manufactured by the South Korean manufacturer Kia since 1993 through five generations. Initially a compact SUV built on a body-on-frame chassis, the second-generation Sportage transitioned to a car-based platform which placed it into the compact crossover SUV class, and was originally developed alongside the Hyundai Tucson and since the fifth-generation model launched in 2021, in two sizes with different wheelbase lengths for different markets, alongside the Hyundai Santa Fe and the Kia Sorento. The Sportage has been the best-selling Kia model globally since 2016 after surpassing the Rio. In 2018, the model reached the 5 million production milestone. As of 2023, the Sportage is positioned between the Seltos or Niro and the three-row Sorento in Kia's SUV global lineup with the latter sharing platform with the Sportage.
