Platform Heritage

The Kia Sorento (Korean: 기아 쏘렌토, romanized: Gia Sorento) is a series of two-wheel drive and four-wheel drive family SUVs manufactured by the South Korean manufacturer Kia since 2002 through four generations. Initially a compact SUV built on a body-on-frame chassis, the second-generation Sorento transitioned to a larger car-based platform which placed it into the mid-size crossover SUV class, and has been developed alongside the Hyundai Santa Fe. It is presumably named after the Italian city of Sorrento, although Kia did not confirm this.
