Jeep will enhance its 2012 model line-up with a trio of 4x4s set to be launched later in 2012 - Grand Cherokee S Limited, Jeep Wrangler Mountain and Jeep Compass Black Edition.Positive consumer interest in the Compass and Grand Cherokee concept cars showcased at the 2012 Geneva Motor Show has inspired the iconic off-road brand to create an all-new Compass special-edition model and a new trim level for its flagship Cherokee.Building on the success of the Wrangler Arctic series, Jeep hopes to attract outdoor enthusiasts with its limited-edition version of the iconic Wrangler.The special edition Wrangler Mountain has a 2.8 turbodiesel engine capable of 150kW at 3600rpm and has peak torque of 460Nm from 1600-2600rpm. The engine can be paired with either a five-speed auto or six-speed manual gearbox but torque is reduced to 410Nm when matched to the manual. A more powerful 3.6 V6 petrol unit is available capable of 211kW/347 Nm and mated to a five-speed auto.MOPAR UPGRADESStyling experts Mopar lent their expertise to the new model in the form of styling updates but, based on the standard Wrangler’s Sport trim, the Mountain will be available in two and four-door versions. The exterior identity includes a black decal on the bonnet, new grille tweaks and glossy 17" rims. The bonnet also has a “Mountain” decal with longitude and latitude co-ordinates. A black fuel-cap is added from Mopar.The interior has fabric seats with grey stitching sporting an embroidered Mountain logo. Mopar treatment in the cabin consists of tread-pattern slush mats and grab handles.The Mountain can be ordered in existing model colours or a new Geko paint job and has been engineered to handle the most challenging off-road tracks. It also has an enhanced Dana 30 front axle and Dana 44 rear axle. Off-road capability is boosted by the standard Comand-Trac NV241 part-time, two-speed transfer case with a 2.72:1 low-range gear ratio.WINTER AND SOUND PACKAGEThis 4x4 system operates on three modes - 2WD, 4WD High and 4WD Low. In normal driving , Comand-Trac operates in 2WD and transfers torque to the rear axle. In 4WD High mode, torque is split 50/50 ratio between the axles. 4WD High provides more torque and traction on the single axles and is to be used only when driving on a slippery surface. The 4WD Low mode is ideal when driving on demanding off-road tracks and provides a 2.72:1 low-range gear ratio that boosts torque on each axle.To aid its off-road capability, standard equipment includes gradient-descent control (for the auto version only) and hill-start help.Optional equipment includes a dual-top configuration, Jeep’s Uconnect infotainment system and the new Winter and Sound Group package, including front heatable seats and a six-speaker audio system.
