The sleek design, combined with Hyundai's expertise in interior packaging, has produced an interior that delivers class-leading comfort, functionality and practicality. A sleek roofline typically compromises headroom and interior volume but, at 120.2 cubic feet, the Sonata has the most interior volume of its key competitors. It is so spacious, Sonata continues to be classified by the Environmental Protection Agency (EPA) as a Large car, truly a “class above” Camry, Altima, Fusion and Malibu (all are categorized as Midsize cars). Even in trunk room, the Sonata shines. Sonata's 16.4 cu. ft. of trunk space gives it a 9.3 percent advantage over the Camry, and a 17.1 percent advantage over Accord.

The new Sonata will launch with Hyundai's new Theta II GDI 2.4-liter four-cylinder engine with a Gasoline Direct-Injection (GDI) fuel delivery system, which contributes to improved fuel efficiency and lower emissions. Sonata is the first midsize sedan to adopt GDI technology as standard equipment in a naturally aspirated powertain. This shorter, more direct path of fuel delivery, allows for greater control of the fuel mixture at the optimum moment, thus improving efficiency. The fuel is injected by a camshaft-driven, high pressure pump that operates at pressures up to 2,175 psi. Direct injection also utilizes a higher than normal 11.3:1 compression ratio for increased power. The pistons are “dished” to increase combustion efficiency in the cylinder. This powerplant will deliver best-in-class fuel economy, best-in-class four-cylinder horsepower and best-in-class torque.

Sonata delivers an impressive 22 mpg city/35 mpg highway fuel economy rating with the available six-speed automatic transmission with SHIFTRONIC®. (When equipped with the six-speed manual, the Sonata achieves 24 mpg city/35 mpg highway fuel economy rating). The preliminary horsepower and torque ratings for the Theta II GDI are 198 horsepower and 184 lb.-ft. of torque. In the SE trim which includes a standard dual exhaust, the engine delivers 200 horsepower. This high-tech, all-aluminum, 16-valve engine features Dual Continuously Variable Valve Timing (DCVVT) and a Variable Induction System (VIS) for better engine breathing. A version of this engine also meets Partial Zero Emission Vehicle (PZEV) standards.

Theta II turbocharged GDI four-cylinder engine and a 2.4-liter Hybrid Blue Drive model featuring Hyundai's breakthrough lithium polymer battery pack. Details about these powertrains will be announced at the 2010 New York Auto Show. Sonata's innovative segment first powertrain lineup is a key driver of Hyundai's goal to be the most fuel-efficient automaker on the planet.

Hyundai's commitment to making the Sonata extremely fuel efficient continues with a six-speed automatic transmission with SHIFTRONIC manual control or a standard six-speed manual transaxle.

Hyundai's all-new six-speed automatic A6MF2 transaxle helps the company meet its goals of improving fuel efficiency and reducing emissions. Shifts are silky-smooth with an option of manual control through the SHIFTRONIC feature.

Drivers can access the SHIFTRONIC feature by moving the gear selector into a separate gate. Pushing the selector forward or pulling it rearward will shift the transmission up or down sequentially, adding to driver control. The SE trim will also feature steering wheel-mounted paddle shifters. A clear LCD readout on the instrument panel shows the gear being used.

Designed for transverse engine applications in passenger cars and SUVs, the new compact transmission puts Hyundai into an elite class of auto manufacturers who have designed their own proprietary six-speed automatic transmissions. The strength of the design is its unique layout which makes it smaller, more compact and lighter than any other six-speed transmission on the market today.

For the customer, the new six-speed delivers a performance edge. In this application, it helps brings a nine percent gain in fuel economy (35 mpg versus 32 mpg). The gearbox has no dipstick because it is filled with automatic transmission fluid that is good for the life of the vehicle under normal usage conditions, thereby reducing maintenance costs.

Developed over a four-year period, this new six-speed automatic is 26.4 pounds lighter than the five-speed it replaces. It also is 1.6 inches shorter and considerably simpler, having 62 fewer parts, which is a key to increased durability, lighter weight and lower cost.

When it comes to transmissions, more gears are definitely better. The addition of a sixth gear enables closer spacing between gear ratios providing a better balance of performance and fuel economy while the wide overall gear ratio helps deliver strong acceleration.

The gearbox has three planetary gearsets and a unique flat torque converter that shortens the unit's overall length by 0.47 inches. Four pinion differentials improve durability and further minimize size.

Another example of engineering ingenuity is found in the design of the hydraulic pressure control unit. Slight manufacturing deviations from one solenoid valve to the next often times cause fluctuation in the hydraulic pressure and affect shift precision and quality. The transmission featured in the Sonata cleverly integrates adjustment screws in the valves that enable each of the eight valves to be calibrated at the factory. This feature ensures stable hydraulic pressure at any shift point which facilitates a high degree of precision and control needed to deliver fast, smooth and precise shifts throughout the rpm range.
