Along with the all-new 2014 Jeep Grand Cherokee, Chrysler Group introduced the segment’s first nine-speed automatic transmission. Despite its complexity, there is only one thing you really need to know about the advanced technology: the nine-speed provides increased fuel economy and performance.
As regulations for fuel efficiency become stricter, automakers are working to meet requirements without sacrificing performance. The nine-speed transmission is Chrysler Group’s solution.
Chrysler Group developed the design for the transmission in partnership with ZF Friedrichshafen.
Because the nine-speed offers a wider range of gears, it allows the engine to operate at its most efficient speed. If that means the engine is able to function most effectively while spinning at a slower rate, the nine-speed’s smaller increments between gear shifts enables it to do so. As a result, less gas is consumed and fuel efficiency increases by up to 16 percent.
Though the gearbox is now home to three additional gears in comparison to the six-speed automatic, Chrysler Group has managed to contain the transmission within a package of approximately the same size and weight.
In addition, the transmission allows drivers to shift through multiple gears at once, adding a little pep to the vehicle’s step.
The Truth About Cars’ website offers a more detailed explanation of Chrysler Group’s nine-speed transmission, which will soon find its way into the all-new 2015 Chrysler 200 and Jeep Renegade. Or, you can just stop by Cumberland Chrysler and do some interactive research in the 2014 Jeep Cherokee.
