Hyundai unveils new fuel-efficient 6-speed automatic transmission

Hyundai has completed development of its new 6-speed automatic transmission that it says will boost fuel-economy by 12.2 percent on some vehicles while using 62 fewer parts than its 5-speed.

“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. Kim said that the new design is so unique and so advanced that Hyundai has applied for nearly 300 patents related to the new technology.

Hyundai will first apply the new 6-speed automatic transmission to the new Hyundai Grandeur (known as the Azera on the stateside) that will be equipped with a 3.3L V6. It will allow the mid-size sedan to accelerate from 0 to 62 mph in 7.8 seconds.

Thew new 6-speed will go into production later this month with a total of five-variants planned. Hyundai said that a total of 16 different Hyundai models will get the transmission including the redesigned Santa Fe that will arrive in late 2009.
