Kia K900 with 650 hp Debuts at SEMA

Fittingly called the "High-Performance" K900, the sedan gets a Garrett 2871R twin-turbo application, which boosts the 5.0-liter V8 engine from its stock rating of 420 hp.

The heady power is underscored by a sinister appearance package, which includes a custom body kit with carbon-fiber inserts, blacked-out chrome trim and 21-inch gloss black wheels. The K900 also has a lowered Eibach suspension and eight-piston brakes with 15-inch cross-drilled rotors.

Inside are tan leather seats with black suede accents. Eleven-inch monitors are mounted in the seatbacks, and the trunk features a specially designed compartment for a racing suit.

Sound good? Don't get too excited: the "High Performance" K900 is only a SEMA show car, and Kia has no plans for production.
