Hyundai Motor America launched its 2.0-liter Theta II turbocharged gasoline direct injection (GDI) engine in 2011 Sonata Auto Show in New York. With the addition of new 2.0-liter Theta II turbocharged GDI offers the new 2011 Sonata is an unprecedented combination of segment-leading fuel economy and power - with an estimated 34 mpg highway rating, and 274 horses . Remarkably, Sonata 2.0T produces these cutting-edge research on regular fuel ... premium is not necessary.
The new Sonata is Hyundai's first vehicle that both the GDI and turbocharging technology. At the end of Hyundai's initiative produced 24 / 7 version 2.0 (seven new models in the next 24 months), four plates are available with GDI or GDI, and the combination of a turbocharger. GDI and turbocharging are part of "Hyundai Blue Drive", the company's environmental initiative to continue the industry leadership in energy efficiency and sustainability.
"The Sonata 2.0T is an excellent example of what our product strategy Drive Blue is for consumers," said John Krafcik, Hyundai Motor America President and CEO. "Think of it - more power than any V6 from our competitors with better gas consumption than any competitive 4-cylinder model that are not fans of engaging Hyundai, the Sonata and really shows. This aspect of our business focus ".
The GDI 2.0-liter turbocharged four-cylinder engine produces 274 horsepower in 2011 and 6000 Sonata rpm 269 lbs-ft of torque from 1800 to 4500 rpm with regular fuel. The 2.0T Sonata will deliver 22 mpg city and 34 mpg highway (preliminary estimates). Hyundai turbo has a twin-scroll turbocharger that when combined with GDI system results in the instantaneous power supply. Twin-turbochargers have been used traditionally in the more expensive high-performance engines, but as with GDI, Hyundai has once again chosen to apply this technology effectively in the high volume of its most popular model.
The 2.0T engine is available on the level of SE and Limited trim with 2.0T Limited additional upgrades, including:
• panoramic sunroof
• 18-inch hyper-silver alloy wheels
• The dual exhaust system
• steering wheel mounted paddle shifters

Twin-scroll turbocharger with GDI and Technology.
Twin-Scroll turbocharger design has two entries in the exhaust gas separated by walls divide the interior of the turbine housing, with two gas passages controlled by a relief valve. A twin-turbo is even more energy from the exhaust of a turbo just because you move to a collector divided. Double entry separates the design of the rollers of which the pulses of exhaust gases interfere with each other leading to improved distribution of pressure in the exhaust and more efficient delivery of energy from the exhaust turbocharger turbine.
For example, two intake valves and exhaust of a cylinder at the beginning of intake stroke of a cylinder, and when it is open (valve overlap period), three-cylinder is already beginning its course of escape of the exhaust valve open. Where exhaust passages of a cylinder and three were closed, would exhaust the cylinder increases against three pulse-pressure cylinder. This will reduce the induction of fresh air and increase the amount of residual hot gases inside the cylinder. But with twin-scroll turbo setup, this interference is minimized.
The result of this analysis of a double-entry design leads to a better distribution of pressure in the exhaust and more efficient delivery of energy from the exhaust turbine of the turbocharger. This in turn allows for more valve overlap, resulting in improved quality and quantity of charge air entering each cylinder. In fact, valve overlap, the effect of sweeping the exhaust stream can literally get more air into the intake side. At the same time highlighting the exhaust gas to lower pressure to help pack on each cylinder with a denser air charge. Maximum gain of the turbo is 17.4 psi.
The design of the twin-scroll turbocharger has several advantages over traditional systems, single turbo scroll, including:
• Improved combustion efficiency
• Motor speed
• The kinetic energy of the exhaust is not wasted or trapped
• The temperature of the bottle cooler
• The low exhaust temperatures
• lean air / fuel ratio
• Increased pressure in the distribution of exhaust vents and more efficient exhaust-gas turbocharger turbine energy
Basically, the Sonata twin-scroll turbo engine with more direct air, the compressor increases the pressure entering the cylinder. This allows the air entering the cylinder is more frequent higher compression and better performance, to promote an efficient and burn more fuel efficiency.
Two main features of Hyundai twin-scroll turbocharger configuration are:
Stainless steel exhaust manifold and twin-scroll turbine housing is cast as a piece of design patents
The turbocharger wastegate controller to use engine power instead of being mechanically
Thanks to the housing of the turbine in the exhaust manifold integrated stainless steel, not just the weight and cost of casting greatly reduced, the durability of the turbine housing is also improved.
Changing the engine to use port electronic boost pressure is controlled with precision. Back pressure is reduced when the turbo boost is not required to open the wastegate, which improves fuel efficiency. In addition, cold starts, the exhaust valve is opened which leads to faster catalyst light-off to reduce exhaust emissions.
A fuel supply system GDI contributes to energy efficiency and reducing emissions. The shortest, most direct delivery of fuel allows a better control of the fuel mixture at the optimum time, thus improving efficiency. The fuel is injected by a camshaft drive high pressure pump that operates at pressures up to 2175 psi. Direct injection also uses a higher proportion of normal compression 9.5:1, while achieving remarkable power 137 per liter. The heads of the pistons are "rounded" to increase the efficiency of combustion in the cylinder.

World-class power to weight, stiffness, and space.
One of his goals for 2011 Sonata engineering team was world-class power-to-weight ratio. This philosophy was also applied to the 2.0T Sonata, with the result of a greater power in its class on the weight of 12.2 horsepower per pound, which is significantly better than any competitor sedan medium size, and even better than the performance-oriented Chevrolet Camaro V6. Power to weight ratio pays dividends to both performance and fuel economy, which is the key to the superior performance of the Sonata in both areas.
In addition, all Sonatas are rich in ultra-high strength steel, which leads to the rigidity of the body of world class. In 2011 the Sonata is 25 percent stiffer in torsion and 19 percent stiffer in bending rigidity than its predecessor, but it is lighter than most sedans medium-sized enterprises, also offering more interior space .
A six-speed automatic.
The commitment of Hyundai Sonata 2.0T to make it extremely fuel efficient continues with a six-speed automatic transmission with manual SHIFTRONIC.
Hyundai new six-speed automatic A6LF2 bridge is another way the company achieves its objectives of improving energy efficiency and reduce emissions. The changes are silky, with a choice of manual control with SHIFTRONIC function.
Drivers can access the SHIFTRONIC feature by moving the shift lever to your door. Pushing the selector forward or pulling the transmission up or down sequentially, adding that the vehicle control. Sonatas turbo mounted levers also feature on the steering wheel. A clear LCD control panel shows the gear used.
Designed for transverse engine applications in cars and SUVs, the new compact Hyundai move to the elite category of car manufacturers who have designed their own country of the six-speed automatic transmissions. Strength of the project is unique in appearance, which makes now a smaller, more compact and lighter than any other six-speed gearbox on the market.
For the customer, to deliver the new six-speed of a performance advantage. The gearbox is not the gauge because it is filled with automatic transmission fluid, which is good for the life of the vehicle in normal use and reduce maintenance costs.
Developed over a period of four years, this new six-speed automatic transmission is 26.4 pounds lighter than the five-speed it replaces. Also is 1.6 inches shorter and simpler, with less than 62 parts, which is the key to a longer life, lighter weight and less expensive.
When it comes to transmissions, more speed is definitely better. The addition of a sixth gear allows more spacing between gears providing a better balance between performance and fuel economy, while the broad overall gear ratio can offer a strong acceleration.
The gearbox has three planetary gear sets and torque converter only dish that shortens the overall length of 0.47 inch drive. Four pinion gear to improve the sustainability and further reduce the size.
Another example of invention is reflected in the design of the control unit of hydraulic pressure. The differences in light manufacturing a solenoid to another are often the cause of fluctuations in hydraulic pressure and affect the accuracy and the quality movement. The transmission appears in the Sonata integrates intelligent screw valves that allow each of the eight valves to be calibrated at the factory. This guarantees the stability of the hydraulic pressure at any point of change that facilitates a high degree of precision and control needed to provide a quick, accurate and smooth through the rev range.
