All models are powered by a 138-horsepower four-cylinder engine. The standard transmission is a five-speed manual; a four-speed automatic is optional. The EX, and SX are four-door sedans. Spectra5 is a five-door hatchback. All are front-wheel-drive compacts that can seat up to five passengers. Safety features include a full complement of airbag supplemental restraints. In addition to the mandatory dual frontal airbags, the Spectra's front-seat occupants are protected by seat-mounted side-impact airbags; while full-coverage side curtain airbags protect both front- and rear-seat occupants.For 2006, the Kia Spectra gets some small trim changes.
