These could be the first images of the Kia K9, a Hyundai Genesis-based large saloon.
The design sketches were shown at a design conference in Seoul, Korea during a speech given by Kia's design boss, Peter Schreyer.
Although details are limited, it's rumoured that the car would be based on the Genesis platform and initially be offered with V8 power in the US, with other markets testing reaction to it.
However, a Kia source denied any knowledge of the car, saying it had not been presented in a forward product plan briefing given earlier this month.
Instead, he suggested that the pictures could be an early design sketch for Kia's K7, which will go on sale as the Cadenza in the US.
