The 2014 Jeep Grand Cherokee will have its debut at the 2013 - and 83rd - Geneva International Motor Show on March 5 and it’s apparently been enhanced on every level.According to the Chrysler Group, the biggest change is the new eight-speed auto gearbox - available across the range - which has reduced fuel consumption and CO2 emissions while improving acceleration and gear shifts. REDESIGNEDThe exterior has undergone some aesthetic surgery, with interior changes depicting each trim level. Changes include new bi-xenon headlights with LED daytime running lights, standard paddle shifts and new colour combinations on the inside and out to set models apart.Image gallery The front-end has a more premium and sportier stance without losing its ground clearance. All models have a shorter upper grille, slimmer headlights and lower front while the fog lights have been raised and are more defined. The rear has larger tail lights with LED lighting, a bigger spoiler and tweaked tailgate for improved visibility. Even the alloys have a new look.Leather and high-quality wood veneer is used and there’s a new three-spoked and leather-wrapped steering wheel in the top-of-the range Summit model. The infotainment offers new contents with the use of the new UConnect system featuring a 20cm touch screen and a configurable display cluster which is standard on all models. KILLER SOUNDFurther items on the Summit trim model include suede-like material covering the front pillars and roof lining. It could also win some serious sound sound-offs with its 19-speaker, 825W HarmanKardon audio system with a 12-channel amplifier and three sub-woofers. Driving these cars are two all-wheel drive systems: Jeep’s Quadra-Lift air suspension system and the Selec-Terrain traction management system. The 2014 model will first be introduced in Italy and the rest of the European market during the third quarter of 2013. It will be available in Laredo, Limited, Overland and Summit trim levels. Further fuel economy is possible thanks to 'Eco Mode' which optimises gear shifting and the fuel-saver cylinder deactivation function in V8 units. For sportier driving, there’s a button on the centre console to deactivate the eco mode. Standard safety systems such as front collision warning with crash mitigation is available across the range. This system uses radar to check the speed of approaching vehicles and will warn the driver of a hazard. If the driver doesn't react the two systems will automatically brake the car to avoid or mitigate an impact.
