Previewing a future D-segment contender
With an overall length of 4.780mm and a 2.800mm wheelbase, the Hyundai i-flow Concept brings new ideas and a pioneering form to the traditional European D-segment. The dramatically-sculpted forms of the interior and exterior make for a striking sports sedan, and its width and height (1.850mm and 1.420mm respectively) give it an athletic stance.
The name i-flow reflects the exceptionally aerodynamic shape and the flowing lines of the concept car's eye-catching styling, and retains the 'i' prefix of Hyundai's established alphanumeric nomenclature for Europe. In 2011 Hyundai will bring into production a new challenger in the segment, drawing on the Hyundai i-flow Concept's sleek styling and innovative technology.
Inside: minimum weight, maximum space and a bionic feel
The interior of Hyundai i-flow Concept redefines the perception of space in a sedan bodystyle. Fundamental elements, such as the seats and center console, were crafted for minimal weight and volume using cutting-edge materials from BASF - one of the world's leading automotive suppliers.
The seats, for example, were developed in conjunction with BASF using advanced stress analysis, which highlighted the unnecessary mass areas and pointed towards an optimized lightweight seat structure. 'Steron', a BASF material, gives the seats a highly-resilient quality, excellent breathability and a high-tech touch.
The upper dashboard, meanwhile, is treated with Elastoskin, a sprayed skin from BASF for a sophisticated, shimmering finish.
This technical, meticulous approach combines with an abundance of natural materials to engender a bionic feel in the cabin, further symbolized by the green color tones and the leaf-like shadows projected from the roof's semi-transparent dye-sensitized solar cells.
The cockpit's main interface centers around an expansive, contoured screen, which recognizes not only touch but also gestural inputs along its fascia-wide display. The fluidic forms of the exterior are echoed in the Hyundai i-flow Concept's cabin, where continuous lines sweep from the dashboard, through the doors to the open storage area at the rear.
BASF and Hyundai R&D engineers have developed thermal engine encapsulation, which ensures that the engine reaches optimum operating temperature more quickly, by retaining heat when the car is at idle. Where a non-insulated engine would take three hours to drop to 40°C, the Hyundai i-flow Concept will stay above that temperature for 14 hours. This translates into fuel savings and emissions cuts of 5 per cent during summer and up to 9 per cent during winter.
Another pioneering technique introduced in collaboration with BASF is thermo-electric waste heat recovery. This process equates to further reductions in fuel consumption, 5% at highest driving. In fact, up to half of the electrical energy consumed by Hyundai i-flow Concept at 80kph - 250 watts - can be recovered through the work of a thermo-electric generator. Harvested energy from hot exhaust gases is recaptured by this generator which is fitted into the exhaust manifold. The thermal electric generator then converts the wasted heat into useful electrical energy to help power auxiliary systems.
Liquid Metal, a coating with the appearance of a glossy skin made of liquid metal, has been developed by BASF Coatings. Special effect pigments in this eco-friendly waterborne coating system let the surface appear as polished metal with targeted mirror like reflections - this gives a liquid skin appearance to the car's exterior and increases the tension of the surface in the same time. The high color saturation on the Hyundai i-flow Concept adds an energizing charisma to the Hyundai concept car. The typical high contrast between highlight and flop underlines the sculptural impact of the Hyundai i-flow Concept.
