Hyundai has developed its own 6-speed automatic transmission, which according to the company makes it just the third major carmaker in the world to have achieved this feat. Hyundai also claims that the new transmission boosts fuel economy by over 12%, while shedding 12kg and 62 parts compared to their 5-speed unit.

The transmission went into production this month and will first arrive in the new 2009 Hyundai Azera (Grandeur) equipped with the 3.3L V6 Lambda engine beginning next month. In this application, it delivers a 12.2% gain in fuel economy from 21.2mpg to a more economical 23.7mpg (10.1km/l versus 9.0km/l) over the 5-speed model. The new transmission is also 2.5% quicker in zero to 60mph (100km/h) acceleration times (7.8sec versus 8.0 sec), as well as delivering an 11% improvement in 37mph to 60mph (60km/h to 100km/h) passing performance (4.0 sec versus 4.5 sec).

A total of five variants of the 6-speed transmission will be produced to accommodate a range of petrol and diesel engines, and a total of sixteen different Hyundai models will get this transmission including the redesigned Santa Fe, which is due to arrive in late in 2009.

Toyota and a joint GM-Ford venture are the only other instances where carmakers have developed their own 6-speed automatic gearbox. Hyundai claims that its own design, however, is markedly superior to similar products from Toyota, GM and Ford due to a number of technical innovations. Additionally, the new 6-speed from Hyundai 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.

The story doesn’t end there as Hyundai is reportedly working on a new 8-speed automatic gearbox that is rumored to debut next year in a brand new flagship saloon.

  3. Actually Hyundais Sonata is more fuel efficient then the Camry, it and the Malibu beat it. The Elantra and the Accent are also very fuel efficient, the Azera could do better though.

  5. Well in regards to the pole tent, must live right next to the water, ocean that is, and lots of salt and never washed. I just sold my Sonata LX 145000 still looks new ! care free miles,beat the hell out of the Cad I had before it. now have a Azera and if it hold up like the Sonata it will outlast me. One of the best I've ever owned and I've owned quite a few. First one was 1919 Model T then a 1921, went up in the world :)

    Hyundai just keeps rolling out the new goodies..must be driving the other car makers nuts! Doesn't Hyundai know the auto improvemnt rules, take tiny little baby steps every year and don't rock the boat?
    This new a/t deserves some serious investigation...how can they leave a/t fluid in and never service the thing?
    All A/T's create wear particles including metal debris that will be swishing around in the thing....for a lifetime?
    This idea scares the hell out of me, as I have a Problem Prone Honda a/t that eats itself into oblivion every 40,000 miles or less. The a/t filter is not changeable and gets plugged, causing low fluid pressure, that causes slipping and overheating and then a $4500 rebuild.
    But wait a min....Oh Ya, Hyundai has a 10 year warranty and Honda doesn't.
