The new 2014 Jeep Grand Cherokee includes even more safety and security features - more than 60, including Front Park Assist, Forward Collision Warning with Crash Mitigation, Adaptive Cruise Control, and Selec-Speed Control - as well as an array of advanced user-friendly technology features for North America such as Uconnect 8.4-inch touchscreen radio with integrated climate and infotainment controls, a 7-inch customer configurable multiview display cluster, Uconnect Access Via Mobile and cloud-based voice texting.
Built in Detroit, the 2014 Jeep Grand Cherokee is available in Laredo, Limited, Overland and Summit models.
All-new clean 3.0-liter EcoDiesel V-6 engine
Enthusiasts in North America have been clamoring for a diesel-powered Grand Cherokee and Jeep has delivered. Producing a class-leading 240 horsepower and massive 420 lb.-ft. of torque, the 3.0-liter EcoDiesel is capable of towing 7,400 pounds - more than any competitor's V-8 equipped SUVs. With a 30-percent increase in fuel economy and a 56-percent increase in torque versus the Pentastar V-6 engine, the EcoDiesel achieves 21 mpg in the city and 30 mpg on the highway in 4x2 models. This allows for a best-in-class driving range of more 730 miles. Full-time 4x4 models have fuel economy figures of 20 city and 28 highway.
The new, 50-state legal, clean 3.0-liter EcoDiesel engine produces low CO2 emissions. MultiJet II common-rail injection and Selective Catalyst Reduction (SCR) help this new engine achieve these results.
The 24-valve, dual-overhead-cam engine features a block and bed plate crafted from strong compacted graphite iron (CGI), which contributes to stiffness without penalizing performance.
The clean 3.0-liter EcoDiesel's 60-degree cylinder banks enable more efficient packaging, while effectively balancing the potent inertia generated by torque-rich diesels.
Driver and passengers alike can expect a smooth, quiet ride on any journey. The new engine's 1-4-2-5-3-6 firing order helps manage rotation so neatly it needs no balance shaft to deliver the level of refinement for which the Grand Cherokee is known.
Further contributing to quieter performance, as well as optimal fuel economy and emissions reduction, is the clean diesel's common-rail fuel-injection system. Its 29,000-psi (2,000-bar) pressure is unmatched by any solenoid-based system.
Swirl-control intake ports benefit from a variable-geometry turbocharger and intercooler that ensure the required engine response, whether merging on-road or surging off-road.
Temperature extremes are also addressed. The new engine's turbo is water-cooled to handle searing heat, while low-voltage ceramic glow plugs accommodate quicker cold-weather starts.
Other key features and benefits include:

Finger-follower actuated valves with hydraulic adjusters

Chain-driven camshafts

Piston-cooling oil jets

Water-cooled exhaust-gas recirculation (EGR) for Tier II, Bin 5 and ULEV II compliance

B5 biofuel compatibility

50-state emission compliance

All-new eight-speed transmission
All three Jeep Grand Cherokee engines are now attached to Chrysler Group's new eight-speed automatic transmission, which provides better fuel economy, quicker acceleration and smoother shifting. Another benefit is a lower crawl ratio of 44.1:1 to aid in climbing over - or through - tough obstacles when equipped with a two-speed transfer case. This is a 46 percent improvement over the previous model's crawl ratio.
"The eight-speed transmission - with a wide ratio spread, high numerical first-gear ratio, quick shifting and aggressive torque-converter lockup - is a major contributor to meeting the Grand Cherokee's ambitious performance targets," said Mircea Gradu, Vice President and Head of Transmission Powertrain and Driveline Engineering. "And it does so without compromising fuel economy."
Robust enough to accommodate the Grand Cherokee EcoDiesel's prodigious torque, the new-for-2014 gearbox delivers not only the promise of durability, but its precise shift schedule enhances ride quality to luxury-car levels.
Fully electronic, the eight-speed automatic features on-the-fly shift map changing, with manual shifting capability and Electronic Range Select using steering-wheel paddle controls. More than 40 individual shift maps for specific conditions optimize shift quality and shift points for fuel economy, performance and drivability. The intelligent software takes into account variables including engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map. Additional parameters integrated into the control strategy include vehicle speed control, electronic stability control interaction and temperature. The result is automatic shifting ideally attuned to the performance requirements of almost any driving demand.
The transmission efficiency and wide ratio spread provide the best possible fuel economy by operating at a lower engine rpm in both city and highway environments. The addition of more gear ratios also helps reduce the gaps normally associated with upshifting and downshifting.
Gear changes are nearly imperceptible due to the evenly spaced gear steps between each gear ratio. Internally, the transmission has four gear sets and five shift elements (multi-disc clutches and brakes). Only two shift elements are open at any time. With fewer open shift elements, drag losses due to multiple parts rotating relative to one another are reduced, improving fuel efficiency.

Eco Mode further improves fuel efficiency
The 2014 Jeep Grand Cherokee features a new Eco Mode that contributes to its improved fuel economy. Eco Mode optimizes the Grand Cherokee transmission's shift schedule and - in V-8 models - Fuel Saver Technology with cylinder deactivation as well as throttle sensitivity to maximize fuel economy. The Eco Mode also manages interactive deceleration fuel shut-off (IDFSO), which cuts fuel delivery when the vehicle is coasting to reduce fuel consumption.
In addition, the Eco Mode activates the vehicle's air suspension system (if so equipped), lowering the Jeep Grand Cherokee to "Aero Ride Height" earlier to improve fuel economy.
Eco Mode is automatically engaged upon vehicle startup. A button on the center stack allows driver's to disengage Eco Mode if more spirited performance is desired.

Air suspension
The 2014 Jeep Grand Cherokee rises above the road and rocks with the rugged Quadra-Lift air suspension system. The Quadra-Lift system features five height settings for optimum ride performance:

Normal Ride Height (NRH): 8.7 inches of clearance offers improved fuel economy as well as improved aerodynamics during on-road driving

Off-road 1: Lifts the vehicle an additional 1.3 inches from NRH for added height in clearing obstacles (10.0 inches)

Off-road 2: Delivers legendary Jeep off-road capability and provides an additional 2.6 inches from NRH for 11.3 inches of ground clearance

Park Mode: Lowers the vehicle 1.6 inches from NRH for easy ingress/egress. NRH and Park Mode are driver selectable allowing the driver full control over vehicle ride height

Aero Mode: Lowers the vehicle 0.6 inches from NRH. Aero Mode is controlled by vehicle speed and adjusts for optimal performance and fuel economy. The vehicle will also lower to Aero Mode when in Sport Mode.

When the vehicle is operating in Eco Mode, it lowers itself to Aero Mode when vehicle speeds are between 52 mph and 56 mph for 20 seconds, or exceeds 56 mph, further enhancing Jeep Grand Cherokees aerodynamics for optimum efficiency.
Quadra-Lift adds up to 4.2-inches of lift span supported by four-corner air springs that provide a cushioned, premium ride. Quadra-Lift operates automatically, or may be controlled manually with console controls.
With the front air dam removed and the available Quadra-Lift air suspension, the 2014 Jeep Grand Cherokee features a 35.8-degree approach angle, a 29.6-degree departure angle and 23.5-degree breakover angle.
The 2014 Jeep Grand Cherokee is also available with load-leveling shocks. When payload is added to the vehicle, the shock's gas pressure increases until the vehicle reaches NRH.
Advantages to load-leveling shocks include improved load handling and trailer-tow performance. Load-leveling shocks are available with trailer-tow packages that do not already have the Quadra-Lift air suspension.
Selec-Terrain
In addition to the Quadra-Lift air suspension, the Grand Cherokee's Selec-Terrain traction control system allows customers to choose the on- and off-road setting for optimum performance. This feature electronically coordinates up to 12 different powertrain, braking and suspension systems, including throttle control, transmission shift, transfer case, Hill-descent Control and Selec-Speed Control.
The Selec-Terrain system has been refined for 2014 and offers five different driving conditions to achieve the best driving experience on all terrains:

Sand: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque tuned for optimal performance in sand

Mud: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque tuned for optimal performance in mud

Auto: Automatically adapts to any on- or off-road situation

Snow: Vehicle traction adjust for ultimate performance over snow-covered roads

Rock: Quadra-Lift suspension raises to maximum height of 11.3 inches, while the transfer case, differentials, and throttle coordinate to provide low-speed control

Sport Mode, previously found on the Selec-Terrain controller, is now engaged with the shift lever. Sport Mode provides enhanced on-road "fun-to-drive" capability.
Selec-Terrain, coupled with the Quadra-Lift air suspension, offers drivers an adjustable suspension span that delivers Trail Rated performance.
Go Anywhere 4x4 Systems
The 2014 Jeep Grand Cherokee features three 4x4 systems - Quadra-Trac I, Quadra-Trac II and Quadra-Drive II.
Quadra-Trac I delivers full-time four-wheel drive without any switches or levers to pull. The system provides smooth operation of the vehicle over a variety of road conditions. This lightweight single-speed transfer case is both proven and efficient for enhanced fuel economy.
Quadra-Trac II's two-speed transfer case uses input from a variety of sensors to determine tire slip at the earliest possible moment and takes corrective action. The system also uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before tire slippage occurs. When wheel slippage is detected, as much as 100 percent of available torque is instantly routed to the axle with the most traction.
Quadra-Drive II, with a rear Electronic Limited-slip Differential (ELSD), delivers industry-leading tractive capability. The system instantly detects tire slip and smoothly distributes engine torque to tires with traction. In some cases, the vehicle will anticipate low traction and adjust in order to proactively limit or eliminate slip.
Selec-Terrain is standard with Quadra-Trac II and Quadra-Drive II.

Selec-Speed Control
Jeep Grand Cherokee offers a new, important capability feature for 2014. Selec-Speed Control features both Hill-descent Control - and brand new Hill-ascent Control. This allows the Grand Cherokee to climb and descend steep grades with minimal driver input.

Technology
An eight-speed transmission and EcoDiesel engine are not the only new technologies in the 2014 Jeep Grand Cherokee - 5-inch and 8.4-inch touchscreens, Forward Collision Warning with Crash Mitigation, adaptive head lamps (Summit only), the latest generation of Uconnect Access and a customizable dynamic gauge cluster heighten Grand Cherokee's premium nature while also adding state-of-the-art safety features.
The 2014 Jeep Grand Cherokee is the first Jeep product to receive Uconnect Access.
"The easy-to-learn, easy-to-use interface found on the new 2014 Jeep Grand Cherokee has become a hallmark of the Uconnect brand," said Marios Zenios, Vice President - Uconnect Systems and Services, Chrysler Group LLC. "Customers will see this manifested again in the advanced connectivity features available in the new Grand Cherokee - a safe vehicle made safer by our emphasis on hands-free functionality."
Advanced safety features such as Forward Collision Warning (FCW) system with Crash Mitigation alerts the driver if they're approaching a vehicle in front too quickly, and Adaptive Cruise Control will keep the Jeep Grand Cherokee at a driver-selected distance from the vehicle in front when cruise control is engaged.

Purtroppo no. Non ho ancora trovato una data di commercializzazione per l'italia.

AleArturo · 16 Gennaio 2013

Mi sembra un'idiozia. Si chiama my2014 per la consuetudine americana di proporre un model year - appunto - ogni anno, ma dubito verrà commercializzato oltre giugno 2013 in Italia.

trovo che il restyling ( tecnico ed estetico ) sia proprio azzeccato. Per esigenze di spazio ( a luglio saremo in 3 ) , cambierò la mia z4 con il jeppone sperando di provare, seppur diverse, altrettanto piacevoli sensazioni. Mi spiace solo che non ho potuto godere in toto della z ( solo 18.000 km ).

Quando sono nato io, mio padre aveva una Saab 900 Turbo Cabrio.

Di certo non era una due posti, ma di certo non l'ha cambiata per una roulotte, visto che ero alto mezzo metro.

Bello! In teoria uscirà a metà 2013.Intanto sull'attuale fanno sconti notevoli sulla Overland.
