2011 Sonata Changing the Hybrid Game

Breakthrough Lithium Polymer Batteries Leapfrog Existing Nickel-Metal Hydride and Lithium-Ion Technology.

Hyundai says its 2011 Sonata Hybrid is changing the hybrid game with unique approaches in hybrid powertrain design, battery technology and vehicle appearance.
The Hyundai-developed Hybrid Blue Drive architecture is a full parallel hybrid drive system, which can operate on an electric motor, gasoline internal combustion engine, and a combination of the two depending on driving conditions and driver demands.
Hyundai's proprietary full parallel architecture differs from the power split technology used by most competitors, allowing significant efficiency advantages at higher speeds. Hyundai Hybrid Blue Drive is the first and only system using lithium polymer battery technology - leapfrogging competitive in-market nickel-metal hydride and lithium-ion applications.
Lithium polymer offers the benefits of lithium-ion, a technology used in laptops and cell phones, but adds robustness, power-density and package flexibility, making it ideal for automotive applications.
Hyundai Hybrid Blue Drive also is unique in its use of the company's own highly efficient, compact new six-speed transmission, modified with hybrid starter-generator, electric motor, and low-friction oil pump, which together allow the elimination of the traditional torque converter.
Hyundai Hybrid Blue Drive is a new addition to a full suite of eco-focused products and technologies that Hyundai offers in its goal to be the auto industry's global eco-leader.
Sonata Hybrid delivers class-leading electric-vehicle operation at steady-state speeds of up to 62 miles per hour. Gasoline engine engagement depends on state of charge, acceleration and vehicle speed.
Its two propulsion units develop a total output of 209 hp at 6,000 rpm, exceeding all mid-size competitors, and 195 lb/ft of torque.
