Yes, you got that right: in the auto industry, more gears means better efficiency. The latest piece of news related to this is linked to Honda, which is expected to introduce a nine-speed automatic that is currently being developed by ZF.
The gearbox could be introduced by the Japanese automotive producer as early as 2014. We are talking about the same unit that will be featured on multiple Chrysler vehicles, such as the Jeep Liberty’s successor.
ZF brags that the unit uses planetary gears instead of a traditional setup, which allows it to be compact despite its complexity. The transmission, which uses the 9HP designation, can cope with up to 345 lb-ft (468 Nm) of torque and is suitable for front- or all-wheel drive layouts. The company claims that its gearbox can increase efficiency by between 10 and 16 percent.
