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.
HYUNDAI`S HYBRID BLUE DRIVE ARCHITECTURE
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.
Engine management software automatically shuts off the engine when the vehicle comes to a halt, cutting emissions to zero. The engine automatically restarts when pressure is reapplied to the accelerator pedal due to the Integrated Starter Generator (ISG).
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.
The nine major components of Hyundai`s Hybrid Blue Drive include:
1.An efficient 30kW electric motor, delivering 205 N-m of torque
2.A regenerative braking system
3.An integrated starter generator that enables the engine to turn off at stops and restart automatically under acceleration
4.A breakthrough lithium polymer battery package, with 5.3 Ah of capacity at 270 volts
5.Optimized Theta II 2.4-liter engine
6.6-speed automatic transmission with an improved-efficiency electric oil pump
7.Weight-efficient architecture coupled with a low drag coefficient
8.Electric air conditioning compressor
9.Hybrid power control unit
LITHIUM POLYMER BATTERY TECHNOLOGY
Hyundai`s hybrid system stores its electrical charge in a 270V lithium polymer rechargeable battery (5.3Ah/270V) that surpasses both existing nickel-metal hydride and pending lithium-ion applications. Lithium polymer batteries are more durable and
space-efficient than other, bulkier hybrid batteries.
Hyundai Assurance allows consumers to walk away from a financing obligation when certain adverse life events occur, providing protection from financial shortfalls that arise from vehicle depreciation (negative equity) up to $7,500. For a limited time, Hyundai is also offering Hyundai Assurance Plus, adding 90 days of payment relief to the existing protection plan. Hyundai Assurance Plus is part of Hyundai`s Spring Sales Event, which runs until April 30, 2009. Hyundai Assurance and Hyundai Assurance Plus are complimentary for the first 12 months of the financing or lease date for vehicles financed through any lender or financing source. The programs supplement all existing consumer incentives, and are available to any consumer, regardless of age, health, employment history or financed amount of the vehicle.
