The teasers keep rolling in ahead of the 2011 Frankfurt Motor Show (IAA) with Kia releasing images of a new four-door sports sedan concept. The powerplant is rumored to be a V8, but all we know for sure about the as yet unnamed car at this stage is that it seats four, is rear-wheel drive and, as you might expect from a concept car, it "signals the company's distinctive new design direction."

The sporty four-door coupe-style layout is a definite break from the compact POP and Naimo concepts shown in recent times, as well as the company's existing Optima sedan. We can see shades of Aston Martin and Jaguar - what do you think of the new design direction?

The Frankfurt Motor Show runs from 15th-25th September 2011.
