Hyundai has released preview images and details of its i-flow concept, which will bow at the 2010 Geneva Motor Show. The concept will be powered by Hyundai's first diesel-electric hybrid power train and should slip through the air with a slippery 0.25Cd drag coefficient.

At the heart of the i-flow's power train his Hyundai's new 1.7-liter turbodiesel engine that shares motivational duties with a yet-undisclosed electric motor and a lithium ion-polymer battery pack. Hyundai also makes no mention of what sort of hybrid system the i-flow will use. Judging by the size of the engine and the six-speed, dual-clutch transmission putting power to the wheels, we can rule out extended range EV (like the Chevy Volt). However, we're still not sure if the concept will be a full hybrid (like the Toyota Prius) or an electric-assist hybrid (like the Honda Insight). What we do know is that Hyundai estimates CO2 output of just 85g/km and fuel consumption of 78mpg (3l/100km).

We'll have more details and live photos of the i-flow concept when it is unveiled alongside an updated Elantra Touring and six other Hyundai world debuts in Geneva next week.
