This could be the next D-segment sedan from Hyundai. The i-flow hybrid concept studies not just diesel-hybrid systems but also something Hyundai is launching in 2011.

Hyundai unveiled the i-flow Concept car in Geneva not only as a possible design study for the company's future products, but also as a test bed for new technology ideas.

At 4.78 metres long, 1.85m wide and 1.4m high, the i-flow is not a small car at all. Actually, it points to a new D-segment family car Hyundai plans to launch in 2011. Its fluidic design, as Hyundai calls it, is very aerodynamic while at the same time aspiring to the new coupe-saloon trend currently seen in a number of European premium cars.

The powertrain consists of a 1.7-litre diesel engine with two-stage turbocharging linked to a Lithium Ion-Polymer battery. It is Hyundai's first diesel-electric hybrid powertrain and is mated to a 6-speed dual-clutch gearbox. The system is said to produce C02 emissions of 85 g/km.
