2011 Hyundai Sonata Hybrid Review

Car manufacturers worldwide prepare the implementation of the timing of new transmission technologies for energy efficiency, such as gasoline direct injection (GDI), a twin-scroll turbocharger, all the power sources and hybrid, Hyundai has announced that the new 2011 Hyundai Sonata is the industry's first vehicle to offer all three technologies, the new Sonata 2.0T (turbo) and Hyundai Sonata Hybrid to join the hot-selling GDI-equipped showrooms in late 2010 Hyundai Sonata.

The 2010 New York Auto Show, Hyundai announced its 2011 Sonata Hybrid, hybrid, unique methods to change the game design hybrid powertrain, battery technology and the appearance of the car. Hyundai Sonata Hybrid is the first hybrid in the U.S. market.

"The Hyundai Sonata Hybrid is the new kid on the block, but it is not a follower," said John Krafcik, president and CEO of Hyundai Motor America. "Its full parallel hybrid configuration, innovative lithium polymer batteries offers a new perspective on the traditional hybrid design, while its unique design sets it apart from the pack mid-sized hybrid."

Hyundai developed the hybrid architecture Blue Drive is a complete parallel hybrid drive, which can run an electric motor, fuel internal combustion engine, and a combination of both, depending on road conditions and driver's needs. Hyundai owners complete parallel architecture differs from the technology division of the energy used by most competitors, leading to significant performance advantages at high speed. Hyundai Blue Hybrid Drive is the first and only technology with lithium polymer - bond market competition in the nickel-metal hydride and lithium-ion applications.

Hyundai Blue Hybrid Drive is also unique in its use even a very efficient company, the new compact 6-speed transmission, modified with the hybrid electric starter generator motor and pump low friction oil, which together help eliminate traditional torque converter.

Hyundai Blue Hybrid Drive is a new addition of a full range of eco-focused products and technologies, Hyundai offers a goal to be the global automotive industry eco-leaders. According to the EPA, Hyundai has led the U.S. industry in fuel economy in 2008 and 2009, and is currently the only automaker with the fleet average fuel consumption by more than 30 miles per gallon.

"Hyundai applies advanced technologies to vehicles to provide the best solutions for the everyday driver," said Krafcik. "Unlike traditional hybrids that trade in the form of fuel economy score above the city, the Hyundai Sonata Hybrid offers best-in-class highway fuel economy while providing an improvement of 40 percent economic front shoulder room compared to the Sonata II theta GDI engine equipped. We believe that this is a more balanced approach to most car buyers. "

 

PERFORMANCE

Hyundai Sonata Hybrid is projected best in class fuel economy of 39 mpg highway offers significant benefits to hybrid owners shuttle highway, while offering outstanding fuel economy of 37 mpg city. Government studies have shown that the typical American driver in a state Highway 57 percent of the time. Hyundai's approach to delivering better fuel economy class on the highway mode gives a unique solution in the market for midsize sedans and differentiate hybrid Hyundai Sonata Hybrid from the likes of Toyota Camry hybrid and the Ford Fusion Hybrid. Hyundai Sonata Hybrid offers hybrid typical fuel economy gains in the city, like its competitors, but also give owners excellent fuel economy on the road where those competitors below.

Hyundai Sonata Hybrid offers first class, the operation of electric vehicles in the steady-state speed of up to 62 mph. The commitment of gasoline depends on the charge state of speeds and vehicles. Its two propulsion units to develop a total power of 209 horsepower at 6,000 rpm, which surpasses all competitors in medium size and 195 lb-ft of torque. The architecture of the actual weight of the new Sonata platform, combined with the light of the lithium-polymer batteries, the Hyundai Sonata hybrid of the lightest vehicles in the segment, only 3457 pounds, 263 pounds lighter than the fusion hybrids. Combined with the highest ranking in the class, Sonata, Hyundai Sonata hybrid has a significant advantage in power to weight ratio, a key factor in performance and efficiency.

Hyundai Parallel Hybrid Drive system really is the heart of the Hyundai Sonata Hybrid. Use the power of competition in the system, a planet-directed continuously variable transmission (CVT). At this point, Hyundai Sonata Hybrid gains a critical advantage. Competing hybrid models use electric motors to power the planetary gear sets. Taking advantage of the entire system in parallel, Hyundai Sonata Hybrid uses the electric motor power more efficiently direct control of the vehicle, so that it can be used at speeds much higher than the competition in the EV-only mode. This technique is also a key factor for Hyundai Sonata Hybrid best-in-class highway fuel economy.

Hyundai blue hybrid drive architecture

Hyundai Blue Hybrid Drive system is a proprietary parallel hybrid that runs on the already fuel-efficient 2.4-liter Theta II engine (169 hp at 6000 rpm and 156 lb-ft of torque at 4500 rpm) coupled a 6 - speed automatic and a 30 kW (151 lb.-ft.) electric motor for maximum fuel economy. Hyundai Blue Hybrid Drive is an all-electric mode and a training mode parallel. This means that the wheels are turned by the power coming directly from gasoline engine or electric motor, or both as conditions demand. This parallel hybrid drive architecture will serve as a basis for future hybrid drive vehicles to be developed by Hyundai.

 

The hybrid system operates Blue Drive Hyundai Theta II multi-port injection (MPI) on an Atkinson cycle. Atkinson cycle is a type of strategy to the internal combustion engine to dramatically increase energy efficiency through changes in the compression stroke and power in the four-stroke engine. It is usually used in hybrid systems where a high torque electric motor increases the low-end power, which is offset by the efficiency of combustion. By combining the electric motor and Atkinson cycle engine offers Blue hybrid propulsion system, the best in their performance class highway hybrid.

To further improve fuel economy, all the Theta II of the main components of transmission and cooling system is optimized to reduce friction, while the crankcase has been filled with low friction oil. Hybrid Control Management Software (HPC) automatically stops the engine when the vehicle stops, reducing emissions to zero. When the pressure is restored to the accelerator pedal, the starter generator hybrid (HSG) automatically restarts the engine. This control strategy ensures that maximum efficiency is reached in the acceleration and more power available immediately at full throttle. During deceleration, braking regeneration comes into play. Hyundai Sonata Hybrid also features "smart braking" in which the input field trips input brake pedal.

High-tech, all-aluminum 16-valve engine has a continuously variable valve timing (CVVT) and camshafts, and the development of new engine parts to reduce friction. The Theta II engine optimized for fuel consumption by 10 per cent more than the traditional Theta II engine.

Hyundai Blue Hybrid Drive your company to use a 6-speed automatic instead of the traditional hybrid CVT. Hyundai Strategy provides for the regulation of a modular six-speed gearbox, replaces the torque converter with an electric motor and an efficient oil pump. This technique uses a traditional step-by-shift six-speed manual gearbox instead of CVT to provide the convertibility of the traditional benefits of the customer and, at times artificially reproduced for CVT applications. This saves costs, Hyundai Blue Hybrid Drive is a better value. This is a more stable and simple and elegant for a complex technical challenge.

 

Improvements in fuel efficiency are evident throughout Hyundai Sonata hybrid. For example, the first three ratios of transmission have been expanded to ensure the engine is running at low speed, electric motor, steering system reduces the demand on the engine and the tire's resistance to low optimization additional fuel.

Lithium Polymer TECHNOLOGY

Sonata hybrid system stores the electric charge in a 270V lithium-polymer battery (5.3Ah/270V) that surpasses existing nickel metal hydride and lithium-ion up applications. Lithium Polymer batteries are more durable and space-efficient than other hybrid batteries. They are also more effective weight. Hyundai Sonata hybrid battery weighs only 95.9 pounds compared to the Camry hybrid is 123.9 pounds. The compact battery lives in the front of the trunk to maximize cargo space.

Versus lithium polymer battery Ni-MH Batteries

Compared to nickel-metal hydride batteries, lithium polymer batteries produce the same output from the weight 20 to 30 percent less, 40 percent less space and more than 10 percent efficient nickel-metal hydride batteries found in hybrid today. Lithium polymer batteries provide 1.7 times more energy density of nickel-metal hydride, which is owned by Hyundai engineers in less space and weight of the battery. Lithium polymer batteries hold charge of 1.25 times longer. Lithium polymer batteries are also more resistant to temperature changes, which improves the service life. In addition, lithium polymer battery self-discharge is less than one third of the nickel-metal hydride battery.

Lithium polymer batteries from lithium-ion

Lithium polymer has significant advantages over lithium-ion, including higher energy density and lower manufacturing costs. Lithium polymer is more resistant to physical damage and can handle more charge-discharge cycles before storage capacity begins to degrade. Lithium-polymer technology also offers significant advantages in terms of durability and thermal safety.

 

The main difference between a traditional lithium ion batteries and lithium polymer solution of Hyundai is to pack the whole cell - anode, cathode, electrolyte, and the coating material. Traditional lithium batteries, such as those found in laptop computers, using what is called the form of 18 650 cells. This form of mass production for each cell is 18 mm. in diameter and 65 mm. high, which is slightly larger than the "AA" batteries. Each of these small metal cylinders filled with a liquid electrolyte, which facilitates the movement of lithium ions across the anode and cathode, the battery generates current.

Traditional lithium-ion batteries are easy to handle, soft to withstand internal pressure, and has been around in various forms since 1991. This means that a manufacturing infrastructure is in place, and economies of scale that is reasonable. But they have several drawbacks. For example, reducing packaging efficiency cylindrical in shape and they are surprisingly complex to produce because they have so many small parts. These small parts which makes them robust against thermal fluctuations and increase significantly the cost and weight of the battery system together. Cell-to-cell consistency is also very critical in a vehicle's battery pack when the pack is only as strong as its weakest cell. Traditional lithium-ion batteries have a high cell to cell variation, while Hyundai lithium polymer batteries offer an excellent cell-cell coherence.

Lithium polymer technology uses a completely different approach. Instead of using a liquid electrolyte, requiring a rugged metal case, lithium polymer batteries use a polymer gel electrolyte, which allows the use of a thin aluminum walls and lighter, frozen, or bag. Inside each cell lithium polymer cathode, a separator and an anode laminated together as production easier and more reliable. This allows the battery to about 20 percent less than a lithium-ion battery, making it much easier to change the cell footprint to fit nooks and crannies of the space of available vehicles.

 

Hyundai and its battery supplier, LG Chem, have spent hundreds of hours of testing at the Disco Blue Hyundai hybrid lithium polymer battery system. This test proves that Hyundai lithium polymer has greater thermal and mechanical stability of existing systems, which means greater security and performance.

Another major technical challenge for Hyundai Hybrid Hard Blue has been to ensure a maintenance-free operation over the life of the battery of the car - at least 10 years and 150,000 miles - in any weather. Heat is an enemy of the life cycle of the battery. Hyundai thermal test shows how much cooler a lithium polymer battery in connection with today's nickel-metal hydride or a conventional lithium-ion battery. Consumers will notice these benefits in terms of improved durability and reduced maintenance costs.
