Hyundai has announced that it has finished developing an all-new six-speed automatic transmission system, one that will feature significant improvements on fuel economy and emission levels.

In a nutshell, the new transaxle is 12.2 percent more fuel-efficient than its current counterpart. Additionally, it is also smaller and lighter—it has 62 fewer parts than the average five-speed auto and is lighter by around 12 kilograms. “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 Project Manager Hong-Min Kim.

The fewer parts and lighter structure makes the new transmission cheaper and easier to maintain. Moreover, Hyundai claims that the system is maintenance-free, with a gearbox guaranteed to be ‘filled for life’ with auto transmission fluid. The sixth gear provides a wider gear ratio and a balance for performance and fuel-efficiency.

The new six-speed will debut on the 3.3-liter Hyundai Grandeur, on which the 12.2-percent fuel-efficiency boost was measured. With such advanced designs and the accompanying benefits, there’s no wonder Hyundai had to apply for 300 patents related to the development of this transaxle.
