Looking into the comparisons, both the Cadenza and Quoris are set to launch in the US sometime in 2013, with release dates for other countries yet to be confirmed.
However, one aspect that allows the Cadenza sedan to break out on its own is that it fully embraces the design language of the Kia's chief stylist, Peter Schreyer.
The result of this decision means that the car's headlights and taillights have been given an overhaul over its predecessor.
What's more, the Cadenza's front and rear bumpers are unlike anything previously seen in the motoring industry, as is its signature 'tiger-nose' grille.
Under the bonnet, drivers can choose between a 148kW 2.4-litre four-cylinder engine, a 198kW 3.0-litre V6 motor or the top-performance 216kW 3.3-litre V6 unit.
The official unveiling of the 2013 Kia Cadenza will take place in Korea in the coming months, where more details of the vehicle is expected to be announced.
