Kia has been discovered to have been working on an all-new, larger and more luxurious sedan. The images that swarmed the internet late last year of the said car are believed to be from a Kia meeting.

The vehicle, which has been tentatively named as K9, will be carrying the same chassis that the Hyundai Genesis sedan has. Powertrain for the K9 is still considering the one the Genesis sedan also has. But a new 4.0 liter V8 rated near 400 horsepower is still not out of the question. Hyundai’s new eight-speed transmission will also make its way into the K9.

The K9 will likely replace the outgoing Amanti in Kia’s lineup. However, it still remains unknown what nameplate the car will bear in production form.

The production for the K9 will start in Korea later this year, and will likely be on sale in the United States presumably in the first quarter of 2011.
