The larger sedans in Kia's 2007 line-up are the recipients of major revisions. All-new for 2007, the Kia Optima is presented with a more mature appearance. Kia's Amanti is highly revised for the 2007 model year. Exterior and interior styling of the sedan has been reworked while a new 3.8-liter V-6 engine replaces the previous 3.5-liter power unit. A new addition to the Kia line-up for 2007 is the Rondo. A front-wheel drive tall wagon, the 2007 Rondo has an interior flexible enough to conform to up to 32 seating configurations. The Kia Sorento features upgraded horsepower for 2007 with the same engine found in the Amanti sedan. Anti-lock braking system and electronic stability control is also added to the standard features list of the 2007 Sorento. The Kia Sedona minivan is now offered in two wheelbase lengths for 2007 with the addition of a shorter wheelbase model. Styling on the Kia Spectra has been mildly updated for 2007 while an input for portable digital music devices is now standard. With the Kia Rio sedan, a new SX trim level is added consisting of standard 15-inch alloy wheels, leather-wrapped steering wheel and a rear spoiler.
