(from Hyundai Press Release) The world will have the opportunity to peer into Hyundai’s future when the Nuvis concept makes its world debut at the 2009 New York Auto Show. The Nuvis is the eleventh signature concept car to be designed at the company’s California Design Center in Irvine, Calif. In addition to showcasing the brand’s cutting-edge capabilities, Nuvis also hints at a possible design direction for a future-generation crossover, blending attributes of a tall urban car and a premium utility vehicle.
Consistent with Hyundai’s pledge to lead all brands in U.S. fuel economy by 2015, Nuvis is powered by Hyundai’s Hybrid Blue Drive architecture, which uses breakthrough lithium polymer battery technology. In developing the initial sketches, Hyundai designers considered the interplay of natural, fluid elements with more rigid surfaces and structures to create the illusion of constant motion. Specifically, designers studied the way water splits across and flows around the hull and sides of a boat, creating a wake, or the way wind shapes a snowdrift or flurries through trees. The living power of these elements is reflected in the Nuvis’ design.
Hyundai’s all-new, homegrown Hybrid Blue Drive architecture helps define the Nuvis concept. Hyundai’s proprietary parallel hybrid drive system mates the already-fuel efficient 2.4-liter Theta II engine to a 6-speed automatic transmission and a 30kW (205 N-m) electric motor for maximum fuel economy.
Hybrid Blue Drive has an all-electric mode and a parallel drive mode, meaning that the wheels are turned by power coming directly from the gasoline engine, or the electric motor, or both together, as conditions demand. This parallel hybrid drive architecture will serve as the foundation for future Hyundai hybrid drive vehicles, starting with the next-generation Sonata in the United States. To maximize fuel economy, all of the Theta II’s major driveline and cooling system components have been optimized to reduce friction, while the crankcase has been filled with low friction oil.
To further reduce fuel consumption, the Theta II’s engine management software, which governs injection pressure, engine cycle timing and exhaust retreatment rates, has been revised. This control strategy assures that maximum efficiency is achieved during gentle acceleration, while greater power is immediately available during full acceleration. During deceleration, regenerative braking also comes into play to help conserve energy. To ensure that the engine runs at lower RPMs, the top three gear ratios in the transmission have been extended. Fuel economy is further optimized through the latest electric motor-assisted steering system which reduces power drain and low resistance tires.
