The Hyundai Tucson is a compact crossover SUV launched in 2004, named after Tucson, Arizona, and developed alongside the Kia Sportage on a shared platform. It has become Hyundai's best-selling model, surpassing 7 million units sold globally, including 1.4 million in Europe. The first-generation model boasted dual-stage frontal airbags, side-impact curtain airbags, and versatile flat-folding seats, with North American trims like GLS, SE, and Limited offering varying features. In 2005, Hyundai unveiled the Tucson FCEV, a hydrogen fuel-cell test vehicle with a 300 km range and a top speed of 150 km/h, which completed a 4,300-mile Hydrogen Road Tour in 2008. The model was marketed under different names worldwide—such as the Hyundai ix35 in Europe and Australia and the Hyundai JM in Japan—while Brazil produced it locally from 2009 to 2018, highlighting its global appeal and adaptability.
