The Kia Opirus was an executive car manufactured and marketed by Kia Motors that was launched in April 2003 and was marketed globally under various nameplates, prominently as the Amanti. It was considered to be Kia's flagship vehicle.
As Kia's largest entry into the executive car market, the Opirus/Amanti had been marketed in a single trim level and only as a sedan. It shared some components with its now-defunct corporate cousin, the Hyundai Grandeur XG, including its 3.5 L V6 engine. For 2007, the Kia Opirus received various upgrades, including suspension and styling revisions, and the addition of the same engine as the current Hyundai Grandeur (Azera), this time being a 3.8 L V6 engine.
In the U.S., the Amanti was recognized as the "Most Appealing Premium Midsize Car" by J.D. Power and Associates' 2005 Automotive Performance, Execution and Layout Study.
The 2007 Amanti outscored several luxury cars in Insurance Institute for Highway Safety (IIHS) side-impact crash testing, to earn the highest rating of Good.
As of December 17, 2010, the Kia website no longer listed the Amanti as a production model. Many critics have noticed the apparent visual similarities to the Mercedes-Benz E-Class (W210).
