Hyundai has joined the plug-in hybrid fray with its BLUE-WILL concept. Silly name, clever car.With the Seoul motor show opening its doors in the first week of April, Hyundai, as South Korea’s premium auto maker, is not keen on being usurped on home turf. Showgoers at Seoul will get a closer look at the BLUE-WILL, which features plenty of clever engineering.Obviously the hybrid drivetrain is BLUE-WILL’s distinguishing feature. It comprises a 1.6l direct injection four-cylinder petrol engine running in partnership with a 100kW electric motor (performance potential appears very keen) with drive managed by a CVT transmission. A lithium-ion polymer battery pack stores power, and being moulded around the fuel tank, luggage- and rear-seat room is impeded as little as possible. Amongst the clever construction techniques employed for the BLUE-WILL are headlights bezels made of recycle cool drink cans, bio-plastics lining the interior and moulding the engine cover. BLUE-WILL’s panoramic roof features integrated dye-sensitised solar cells too.Hyundai’s hybrid vehicle initiatives are not the simple folly of design magazine features and motor-show concepts either. The company is aiming to become the first global auto maker to offer a mass-produced, lithium-ion polymer battery pack powered hybrid vehicle, when the Elantra LPI goes on sale in South Korea this July.
