2012 Jeep Grand Cherokee gets new Chrysler's ZF-developed eight-speed automatic gearbox as a standard equipment for the base V6 models. The optional 5.7-liter HEMI V8 power unit is going to receive a six-speed automatic transaxle for the 2012.
Chrysler hasn't announced fuel efficiency ratings for the 2012 Grand Cherokee V6, but it is expected to receive a 1 to 2 mpg gain. The fuel economy of the current all-wheel-drive model is estimated 6 mpg in the city and 22 mph on the highway. The eight-speed transmission may also lead to a revised gear lever resembling the control knob found on the 2012 Land Rover Range Rover Sport. According to the WK2Jeeps.com, all V6 models will have a new electro-hydraulic steering system, another step made to reduce fuel consumption.
The company will start the production of the 2012 Grand Cherokee next week. The new model will be available on the market in late August.
