World-class weight efficiency was one of the program targets for the Hyundai Tucson engineering team. In fact, the 2010 Tucson leads all of its competitors in weight efficiency. Hyundai engineers also targeted leadership in power-to-weight ratio. Having these targets paid huge dividends in both performance and fuel economy.

The Hyundai Tucson's widespread use of high-strength steel provides increased strength at a lower body weight. High-strength steel allows the four-wheel independent suspension to work optimally. At 3,203 pounds for an automatic transmission model, the Tucson is lighter than its competitors, while offering more interior room than Rogue and Escape, with body-bending rigidity 38 percent higher than the Rogue. The Tucson owes its 31 mpg estimated EPA highway rating to its weight efficient unibody architecture.
