Here’s another image of the Hyundai i-flow concept which will be unveiled at Geneva next week. The i-flow, which advances the ‘fluidic sculpture’ design language Hyundai currently uses on cars like the new Sonata and Tucson, previews a future D-segment contender, according to the Korean carmaker.

Under the sheetmetal is Hyundai’s first diesel-electric hybrid powertrain. The package consists of a new 1.7-litre engine with two-stage turbocharging, lithium Ion-polymer batteries and a six-speed, dual-clutch transmission. Combined with drag coefficient of 0.25Cd, the i-flow’s CO2 output is a low 85 g/km and it only consumes three litres of fuel for every 100 km (33.3 km/l).

Hyundai says that the i-flow cabin “redefines the perception of space in a sedan bodystyle”, and this concept will use next-generation materials and technologies co-developed with top chemical company BASF. Elements such as the seats and centre console has BASF’s input for minimal weight and volume, while the cockpit’s main interface screen recognises not only touch but also “gestural inputs”. The glossy Liquid Metal eco-friendly waterborne coating developed by BASF Coatings contains special-effect pigments that give the surface a polished metal appearance, good for highlighting the car’s complex lines.

Also making their debuts will be the facelifted i30 (with cleaner powertrains and enhanced spec, production starts next month) and eco focussed Blue Drive variants for the i10, i20, i30 and ix35 (European version of the Tucson). All Blue Drive cars except the SUV produce less than 100 g/km of CO2. One step beyond the blue-badged models is the ix35 FCEV which shows Hyundai’s latest hydrogen fuel cell tech. The show car features steps to reduce cost and complexity of fuel-cell manufacturing as well as new approaches which simplify final assembly, leading to full production in 2012.
