Hyundai has released design sketches of its latest concept car ahead of a world premiere at the 2013 Seoul Motor Show later this month. Like the HCD-14 Genesis concept shown in Detroit, the HND-9 concept aims to spell out the company's future design direction for its luxury offerings – this time with an extra dose of sporty.

The HND-9 is described as "a modern interpretation of a classic premium sports coupe" and apart from the butterfly doors and some interesting curves on all four corners, the renderings suggest the HND-9 leans towards the less radical side of such an interpretation – which isn't to say it's without appeal.

Technical details are scarce – rear-wheel drive with a 3.3-litre turbo GDi engine married to an 8-speed auto transmission for a maximum output of 270 kW. That's all we know until Hyundai lifts the lid on the HND-9 in Seoul on March 28.
