Introduced last year, the SX trim of the 2008 Kia Spectra is the sports version of the budget midsize sedan. It takes most of the attributes of the Spectra5 hatch and converts them to a sedan. Though it has the same 2.0-liter, 138-hp DOHC inline-four engine and choice of 5-speed manual or 4-speed automatic, the front-wheel drive 2008 Spectra SX sits on a sport-tuned front and rear independent suspension and rides on larger 16-inch alloy wheels. Other sport features include ground effects, a larger anti-sway bar, stronger shocks, and standard foglights. Flashy touches on the inside included aluminum pedals, sport seats, and leather trim. It also gets tweaks to the front and rear ends and adds a front spoiler to the already standard rear spoiler.

Inside, the 2008 Spectra SX offers similar standard equipment to the EX, such as full power features, heated mirrors, remote entry, cruise control, a CD player with MP3 input, intermittent wipers, tilt steering, and front and rear cupholders. Unlike the other trims, 4-wheel ABS brakes are available as an option on the SX. Otherwise, it comes with 4-wheel disc brakes, a tire monitor, and dual front-side and side curtain airbags. Rear seats split-fold and the trunk holds 12 cubic feet. In addition to the 6-CD changer option, the 2008 Spectra SX can be outfitted with remote start and a sunroof.
