The 5-seater Jeep Grand Cherokee has received a facelift as well as a few mechanical upgrades for the 2014 model year. Offered with a choice of the 3.6-litre "Pentastar" V6 or the 5.7-litre "Hemi" V8, both come with a new 8-speed automatic, four-wheel-drive with low-range and four trim levels. The introduction of the 8-speed automatic transmission boosts fuel economy numbers. The base Laredo is V6 only, the Limited can be V6 or V8, and the Overland is V8 only. Another trim level introduced for 2014 is the Summit which also comes in only V8 form. The SRT8 version gets a name-change to only "SRT" for 2014, as well as a 6.4-litre V8, 8-speed automatic and all-wheel-drive with no low-range. For non-SRT versions, depending on trim level, there is a choice of two 4x4 systems, Quadra-Lift air suspension on the Overland, and a new Selec-Terrain system with crawl control. The Mercedes-Benz-derived platform has independent front and rear suspension, stiffer new body structure and more space. A new added feature on all models is the new 8.4-inch touchscreen display and 7-inch customer configurable multiview cluster display. Even the Laredo is well-equipped, with body-colour bumpers, 17-inch or 18-inch alloy wheels, power driver's seat, dual-zone manual a/c, keyless start, CD/MP3 stereo, cloth upholstery, HID automatic headlights, fog lamps, and the usual power accessories. The Limited adds leather, Alpine premium audio, automatic a/c, panoramic roof, 18-inch wheels, rain-sensing wipers, navigation, 30GB hard drive and UConnect Bluetooth phone. The Overland adds chrome bumper trim, painted wheel arches, real leather, real wood trim, stitched-leather dash trim, ventilated power-adjustable front seats, 9-speaker audio with subwoofer and 20-inch wheels, with various options and accessories available. The Summit has similar options to the Limited, with the addition of a unique SRT-like front bumper, more premium leather and wood panels for the interior. The SRT8 version gets a unique body kit, sports suspension, sports seats and other trim bits. Safety features available include standard active head restraints, front airbags, full-length side-curtain and seat-mounted side airbags, stability control, electronic roll mitigation, hill-start assist and optional trailer-sway control. An optional blind-spot/rear cross-path detection system and adaptive cruise control with forward collision warning are also available.
