As a global car to work outside of time to implement new technological systems such as propulsion fuel injection to save fuel Direct (GDI), a twin-scroll turbocharger, and full-hybrid powertrain, Hyundai announced that the newly-2011 Hyundai Sonata is the first vehicle in the industry to offer all three technologies with the new Sonata 2.0T (turbo) and the Hyundai Sonata Sonata hybrid join GDI equipped with hot-selling Hyundai dealers at the end of 2010.
On the New York auto show in 2010, has launched the Hyundai Sonata Hybrid in 2011, changing the game in hybrids with a unique approach to the design of hybrid drive systems, battery technology and performance vehicles . Hybrid Hyundai Sonata is the first hybrid vehicle on the U.S. market.
“The Hyundai Sonata hybrid is the new kid on the block, but not a follower,” said John Krafcik, President and CEO, Hyundai Motor America. “The full configuration and a parallel hybrid battery Lithium-polymer that offers a breakthrough in design to traditional hybrids, while the unique design that distinguishes it from the packaging of a hybrid environment. ”
the architecture of hybrid Hyundai developed by Blue is a complete system of parallel hybrid that can run on an electric motor, fuel internal combustion engine, and combining the function of two on driving conditions and requirements of the driver. Hyundai full parallel architecture is different from the power distribution technology that is used by most competitors, so that significant efficiencies at higher speeds. Hyundai Blue Hybrid Drive is the first and unique system uses a battery technology lithium-polymer – a jump on the competitive market of nickel metal hydride and lithium-ion applications. Offers the advantages of lithium-polymer lithium-ion technology used in laptops and cell phones, but adds robustness, power density and flexibility of supply, making it ideal for automotive applications. Hyundai Hybrid Blue Drive are also unique in its own programming appeals to a very efficient company, the new compact 6-speed, modified with a hybrid starter generators, electric motors, oil pump and low friction, which together allow the elimination of conventional torque converters.
Hyundai Blue Hybrid Drive is a new addition to the full range of eco-centric products and technology that Hyundai has the goal of becoming a green industry global auto-leading. According to the EPA, Hyundai has led the U.S. industry in fuel economy for the years 2008 and 2009, and currently the only automaker with the fleet average fuel economy of over 30 miles per gallon .
“Hyundai demand for vehicles with advanced technologies to provide the best solutions for everyday drivers,” said Krafcik. “Contrary to the traditional trade off hybrid economy of the town highway fuel for a higher rank, Hyundai Sonata Hybrid offers better fuel economy drive in its class, while providing approximately 40 percent improvement in fuel economy in town compared to the Sonata II is equipped Theta GDI engines We think this is a more balanced approach of most car buyers .. ”
Hyundai Sonata hybrid projections best in class fuel economy of 39 mpg highway offers considerable advantages for owners of hybrids with traffic congestion, while the city also offers exceptional fuel 37 mpg. Government studies have shown that drivers typically operate on U.S. highways 57 percent of the time. Hyundai’s approach to provide fuel economy leader in highway mode provides a unique solution on the market hybrid midsize sedan, Hyundai Sonata and differentiate people like the hybrid Toyota Camry Hybrid and Ford Fusion Hybrid. Hyundai Sonata Hybrid offers the benefits of the hybrid fuel economy is generally in cities such as competitors, but also gives the owner of the outstanding fuel economy on the highway, where those competitors below.
Hyundai Sonata Hybrid gives class-leading electric vehicle operating with speeds of steady state up to 62 miles per hour. Gasoline engines cost participation based on the circumstances, the acceleration and vehicle speed. His two propulsion units to develop the total output of 209 hp at 6,000 rpm, more means of any competitor, and 195 lb-ft of torque. the architecture of effective weight of the new Sonata platform, combined with a light lithium-polymer battery, to a Hyundai Sonata mild “hybrid vehicles in its class, only 3457 pounds, 263 pounds less than the Fusion hybrid. Combined with the rated best in class Sonata, Hyundai Sonata Hybrid has a significant advantage in the ratio of power-weight ratio, a key factor in the performance and efficiency.
parallel hybrid drive system for Hyundai is the heart of the Hyundai Sonata Hybrid. Competition using a split system with electric planet headed continuous transmission (CVT). This is where Hyundai Sonata Hybrid gains the main advantages. The competition model using hybrid electric motors with a power set of teeth of the planet. By exploiting a parallel drive system is full, the Hyundai Sonata Hybrid uses electric power engine is more efficient to directly control the vehicle, allowing it to operate at much higher speeds than the competition only in EV mode. This technology is also a key factor in better fuel economy in its class road Hyundai Sonata Hybrid.
Hyundai architecture HYBRID Blue Drive
Hyundai Blue Hybrid Drive is owned by a parallel hybrid system that runs on the 2.4-liter engine that has fuel efficient Theta II (169 hp at 6,000 rpm and 156 lb-ft of torque at 4500 rpm ) coupled to a 6-speed automatic transmission and 30 kW (151 lb-ft) electric motor for maximum fuel economy. Hyundai Blue Hybrid Drive is the all-electric mode and a parallel drive mode. This means that the wheels are turned by the power coming directly from gasoline engines, or electric motor, or both as conditions demand. Parallel hybrid drive architecture will serve as the foundation for future hybrid vehicles that will be developed by Hyundai.
In Hyundai Blue Hybrid Drive, Theta II multi-port injection (MPI) operates on the Atkinson cycle. Atkinson cycle is the type of strategy internal combustion engine designed to dramatically improve energy efficiency through changes in the compression and power stroke four-stroke engine. This is typically used in hybrid systems where high-torque electric motor to improve power at low rpm, which is traded off efficiency in internal combustion engines. By combining an electric motor and motor cycle Atkinson, Blue Hybrid Drive system provides best-in highway-class efficiency hybrid.
To further improve fuel economy, all major Theta II transmission and cooling system components have been optimized to reduce friction, while the crankcase has been filled with low friction oil. Hybrid Power Control (HPC) software of automatic engine shutdown when the vehicle stopped ahead, reducing emissions to zero. When pressure is applied back to the gas pedal, hybrid Starter Generator (HSG) automatically restarts the machine. This control strategy ensures that the maximum efficiency achieved during the smooth acceleration and greater power is immediately available for full acceleration. During deceleration, the role of regenerative braking. Hyundai Sonata Hybrid also offers “smart braking” technology in which the input-brake lines to the accelerator pedal input.
That is, high-tech all-aluminum, 16-valve engine also has variable valve timing A (CVVT) on both camshafts and engine components newly developed to reduce friction. Theta II engine is optimized to achieve 10 per cent of fuel consumption over conventional Theta II engine.
Hyundai Blue Hybrid Drive through the processes of automatic transmission 6-speed CVT is not a conventional hybrid. Hyundai’s strategy involves an adaptation of the modular 6-speed transmission with torque converter, replaced by electric motors and high efficiency oil pump. This technique uses a phase shifter traditional 6-speed CVT does not move to offer a more traditional is preferred by customers and sometimes artificially reproduced in applications of CVT. This saves cost, make Hyundai Blue Hybrid Drive a better value system. This is a more powerful and elegantly simple solutions to complex engineering problems.
Improving energy efficiency evident throughout the Hyundai Sonata hybrid. For example, the first three gear ratios of transmission has been extended to ensure that the engine runs at low speeds, the electric motor control system has reduced the demands on the engine and low-resistance tires in addition to optimize fuel economy.
Blue Hybrid Drive main components consist of the following:
* An efficient electric motor that provides 30 kilowatts 151 pounds-feet of torque
* A braking system
* An integrated starter generator that allows the engine to stop and disable the automatic restart acceleration
* A lithium polymer battery pack breakthrough, with a capacity of 5.3 Ah to 270 volts

Technology Lithium polymer
Sonata hybrid system stores electrical charge in a rechargeable lithium polymer 270V (5.3Ah/270V) that goes beyond the existing nickel metal hydride and lithium-ion applications waiting. Lithium-polymer is more durable and space-efficient than other batteries hybrids. They are also more effective weight. Hyundai Sonata hybrid battery weight is only 95.9 pounds versus Camry Hybrid 123.9 pounds. Compact battery located at the front trunk to maximize cargo space.
Lithium-polymer batteries vs. nickel-metal hydride
Compared with nickel-metal hydride batteries, lithium polymer battery provides the same power with a weight of 20-30 percent lower, less volume of 40 percent and 10 percent greater efficiency over nickel-metal hydride is TODAY ‘hui hybrids. lithium polymer battery provides 1.7 times more energy than the density of nickel-metal hydride, allows engineers to spend less Hyundai Space and weight of the battery. lithium polymer batteries to keep their costs 1.25 times longer. lithium polymer batteries are also more resistant to temperature changes, which increase the life cycle. In addition, the polymer self-discharge rate of lithium is less than one third of the nickel-metal hydride.
Lithium Polymer Battery Lithium-ion cons
Lithium-polymer has significant advantages over lithium-ion batteries, whose higher energy density and low production costs. Lithium-polymer is more resistant to physical damage and can handle more charge-discharge cycles before storage capacity began to deteriorate. Lithium-polymer technology also offers significant advantages in heat resistance and safety.
A key difference between conventional batteries lithium-ion and lithium polymer packs solution is Hyundai cell – anode, cathode, electrolyte, and packaging material. Traditional lithium ion batteries, like those found on laptops, using what is called the cell format 18650th. In this format, each cell produces bulk is 18 mm. a diameter of 65 mm. high, which is slightly higher than the battery AA. Each of these small metal cylinders filled with a liquid electrolyte that facilitates the movement of lithium ions in the anode and cathode, creating a stream of battery.
Traditional lithium-ion battery is easy to handle, resist the internal pressure of light, and has been around in various forms since 1991. This means that the manufacturing infrastructure in place and economies of scale are very high. However, they have several weaknesses. For example, the shape of a cylinder which reduces the efficiency of the packaging and surprisingly complex to produce because they have so many small pieces. Small pieces to make them stronger thermal fluctuations and increase significantly the cost and weight of the battery system as a whole. coherence between the cells is also very important in the vehicle’s battery, because this package is only as good as the weakest cell. Traditional cell lithium-ion changes in the cell, while the lithium-polymer ensures consistency Hyundai circulating cell to cell.
Lithium-polymer technology uses a completely different approach. Instead of using a liquid electrolyte, which requires a rugged metal, using lithium-polymer gel polymer as an electrolyte, which allows the use of the envelope wall aluminum thin and light, or pouch . The interior of each cell lithium polymer cathode, a separator, and anode are glued together, which allows much simpler and more reliable manufacturing. This allows the battery to about 20 percent smaller than the lithium-ion battery, which makes it easier to change the footprint of cells to fit the niche and cranny of space vehicles.
Hyundai and suppliers of batteries, LG Chem, has spent hundreds of hours of testing Hyundai Blue Hybrid Drive system of a lithium-polymer. This test proved that the lithium-polymer Hyundai has greater thermal and mechanical stability of the existing system, which means better security and performance.
Another major technical challenge for Hyundai Blue Hybrid Drive has provided a maintenance-free battery operation for the vehicle – at least 10 years and 150,000 miles – in all weather conditions. Heat is the enemy of the life cycle of battery. Hyundai thermal imaging test showed how cooling a lithium-polymer relative to nickel-metal hydride batteries now or conventional lithium-ion batteries. Consumers will see the benefits of this good life and useful maintenance costs.
