Chrysler unveils 2014 Jeep Cherokee

Chrysler Group mashes the throttle on engine, transmission and driveline debuts for model-year 2014.

The introductions, which span multiple model lines, send a clear message to the world.

"We are steadfast in our commitment to innovate for the benefit of our customers," said Mircea Gradu, vice president — powertrain transmission and driveline engineering and head of virtual analysis. "Nowhere is this more evident than on the all-new 2014 Jeep Cherokee."

The all-new Cherokee's stylish appearance belies the rugged capability delivered by its unique 4x4 system.

It is the first mid-size sport-utility (SUV) to feature a front-wheel-drive-based rear-axle disconnect system. It delivers four-wheel traction whenever it's needed, without driver intervention. 

A fully variable wet clutch housed in the rear drive module supplies the proper amount of torque for any traction condition. This capability also is a boon to aggressive starts.

Sophisticated algorithms enable the system to benefit driving dynamics by interacting with electronic stability control (ESC). When conditions are more favorable, it seamlessly switches to two-wheel-drive for optimum efficiency.

The system is available with either a one- or two-speed driveline (PTU and RDM). A locking differential is available with the two-speed PTU.

In low range, the 2.92:1 gear reduction also sets up aggressive crawl ratios – 56:1 when the vehicle is powered by the 2.4L Tigershark I-4 engine, and 47.8:1 when powered by the new 3.2L Pentastar V-6. Such specifications benefit off-road performance.

An available locking rear differential enhances control in extreme off-road conditions and is selectable in any low-range terrain mode.
