Hyundai Working On 10-Speed Transmission

Hyundai just does not want to leave the pages of auto publications lately. The Korean automaker is reportedly working on improving its high-end offerings with a 10-speed automatic transmission. The gearbox, which adds an extra two gears over the eight-speed equipped to the 2012 Genesis and 2012 Equus, is being developed for future high-end models.

Hyundai Motor Group president Park Seong Hyon told Bloomberg that the 10-speed boxes will be reserved for luxury offerings and will debut in 2014. It's likely that the 10-speed will be used in the Equus and Genesis.

If you're wondering why you're seeing increasing numbers of gears to the tune of seven, eight, and now 10, it's because more gears equates to more efficient driving. According to a 2008 Edmunds article, more gears equates to more efficient engines, but there is a point at which too many gears can actually start to hinder fuel economy. With Hyundai committing to a 10-speed transmission, we're not quite sure when that point will come. A statistic cited in the article indicates that six-speed automatic transmissions boost fuel economy by four to six percent over four- and five-speed automatic transmissions.

ZF, a German transmission manufacturer whose gearboxes are used in cars from BMW, Bentley, and Audi, unveiled a nine-speed automatic transmission earlier this year promising "significant fuel economy improvements" that the company feels could be as much as 16 percent over the more ubiquitous six-speed. Chrysler plans to use the nine-speed in some of its vehicles.
