Based upon a heavily modified Elantra platform, the Tucson has a longer wheelbase, shorter length, and greater width than its key competitors. Lighter than the Escape and the CR-V, the 2005 Hyundai Tucson also features more front leg room than those two models, and exceeds both the Escape and RAV-4 in terms of rear seat leg room. Other interior dimensions stack up competitively, including cargo space, which measures 22.7 cubic feet with the rear seat raised and 65.5 cubic feet with the rear seat lowered.

Hyundai sells the Tucson in three well-equipped trim levels: GL, GLS, and LX. All Tucsons come with front side-impact airbags, side-curtain airbags for the front and rear occupants, a stability control system, a traction control system, and antilock brakes. In fact, the 2005 Hyundai Tucson is the least expensive vehicle equipped with side-curtain airbags and stability control.
