Default Hyundai Reveals New Six-Speed Auto Transmission




Quote:
Set to be rolled out on selected models in 2009 onwards, Hyundai's new six-speed automatic transmission promises to boosts fuel economy by 12% and is 12kg (26.5 lbs) lighter and has 62 fewer parts than a 5-speed auto transaxle. With the introduction of the new transmission, Hyundai becomes only the third company in the world to develop its own six-speed automatic transaxle after Toyota and a GM/Ford joint venture.

Designed for transverse engine applications in cars and SUVs, the new compact transaxle that went into production in December will be offered in a total of five variants to accommodate a wide range of petrol and diesel engines. Overall, 16 different Hyundai models will get this transmission.


"The strength of our design is its completely unique layout, which makes it smaller, more compact and lighter than any other six-speed on the market today," said Hong-Min Kim, the project manager of the transaxle at Hyundai R&D Centre.

The new tranny will make its debut in the new Hyundai Grandeur equipped with a 3.3-litre V6 petrol engine. Hyundai said that in this application, the new gearbox delivers a 12.2 percent gain in fuel economy and is 2.5 percent quicker in zero to 62mph (100km/h) acceleration times (7.8sec versus 8.0 sec).It also delivers an 11 percent improvement in 60km/h to 100km/h overtaking performance (4.0 sec versus 4.5 sec).

Good stuff. Hyundai is making a lot of good moves. I am seriously tempted to get the Genesis turbo coupe.

In this previously established (near universal) enthusiast understanding DSG and "Auto" are dissimilar in principle design layout and thus non comparable within the pertinent context of this thread.General majority of thread participants assumed to be in similar versions of like mindedness with above statements.

Remaining participants will inevitably be shunned for seemingly random logic less ramblings which may or may not simply be wholly or partly due to a general lack of knowledge on thread subject matter.

This is the third 6-speed conventional auto that Hyundai offers. They have a longitudinal 6-speed for the V6 Genesis, a ZF for the V8, and now this for front drive models. Very comprehensive.

Hyundai Develops Own Six-Speed Automatic for Improved Fuel Efficiency

- Hyundai becomes 3rd company in the world to develop own 6-speed automatic transaxle
- New transaxle boosts fuel economy by 12%, is 12kg lighter and has 62 fewer parts than a 5-speed
- First application will be in Grandeur/Azera models beginning in January 2009

(Seoul, Korea) To help meet its goals of improving fuel efficiency and reducing CO2 emissions of its vehicles, Hyundai Motor Company has completed the development of an all-new 6-speed automatic transaxle that will boost fuel economy by more than 12.2 percent.

Designed for transverse engine applications in passenger cars and SUVs, the new compact transaxle puts Hyundai into an elite class of auto manufacturers who have designed their own proprietary 6-speed automatic (after Toyota and a GM/Ford joint venture) demonstrating Hyundai’s advanced powertrain engineering capabilities.

"The strength of our design is its totally unique layout which makes it smaller, more compact and lighter than any other 6-speed on the market today," said Hong-Min Kim, the project manager of the transaxle at Hyundai Motor’s R&D Center. In fact, the design is so unique and so advanced, Hyundai has applied for nearly 300 patents to protect its intellectual property.

For the customer, the new six-speed promises a performance edge. The transaxle will first arrive in the new Hyundai Grandeur/Azera equipped with a 3.3-liter V-6 Lambda engine. In this application, it delivers a 12.2 percent gain in fuel economy (10.1km/l versus 9.0km/l) and is 2.5 percent quicker in zero to 100km/h acceleration times (7.8sec versus 8.0 sec). It also delivers an 11 percent improvement in 60km/h to 100km/h passing performance (4.0 sec versus 4.5 sec).

The unit also is maintenance-free: The gearbox is not equipped with a dipstick as it is filled with an automatic transmission fluid that is good for the life of the vehicle thereby reducing maintenance costs.

Developed over a four-year period, this new 6-speed automatic gearbox offers numerous technical merits. Despite the extra gear, it's 12kg lighter than the 5-speed it replaces. It also is 41mm shorter and considerably simpler having 62 fewer parts, which is a key to increased durability and lower cost.

When it comes to gearsets, more is 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 whose hallmark is simplicity of design and a unique flat torque converter which shortens the unit's overall length by 12mm. Four pinion differentials improve durability and further minimize size.

Another example of engineering ingenuity is to be found in the design of the hydraulic pressure control unit. Because there are always slight manufacturing deviations from one solenoid valve to the next which cause fluctuation in the hydraulic pressure and affect shift precision and quality, the transaxle features cleverly integrated adjustment screws in the valves which enable each of the eight valves to be calibrated at the factory.

This novel feature ensures stable hydraulic pressure at any shift point which facilitates a high degree of precision and control needed to deliver ultra-fast, smooth and precise shifts throughout the rpm range.

The new 6-speed went into production this month (December) and will see its first application in Grandeur/Azera models beginning in January 2009. A total of five variants of the 6-speed transaxle will be produced to accommodate a wide range of gasoline and diesel engines. A total of sixteen different Hyundai models will get this transmission including a redesigned Santa Fe, which is due to arrive in late in 2009 and early 2010 in some markets.

When I saw the thread title, I thought; great another 6spd auto tranny. But then, I read the part about how Hyundai actually designs and builds this trans and I wholeheartedly agree; great job! Not too many car companies build their own trannys anymore. Most outsource them. Hyundai is definitely becomming one of the worlds foremost car manufacturers.

This is a 6-speed Transaxle for the FWD Hyundais, such as the Sonata.

The V6 Genesis gets a homegrown 6-speed auto, while the V8 gets a ZF (used by the big German guys).

Good for Hyundai. That seems like quite a massive effort with a nice end result. I am sure this will help them achieve the upcoming MPG standards.
