All-new 2018 Jeep® Wrangler Delivers Legendary Off-road Capability With Improved On-road Driving Dynamics
The all-new 2018 Jeep® Wrangler receives a multitude of enhancements versus its predecessor to optimize the ride, handling and sound characteristics while reducing weight and improving fuel economy. Utilizing a body-on-frame design and featuring a five-link suspension system, Wrangler delivers even more capability, with improved on-road driving dynamics, ride comfort and passenger safety.
"The all-new 2018 Jeep Wrangler is an authentic Jeep SUV that further improves on its legendary off-road capability," said John Mrozowski, Vehicle Line Executive - FCA US LLC. "Additionally, the new Wrangler adds improved on-road driving dynamics and comfort in all weather conditions."
Proven body-on-frame design is the foundation for legendary Jeep capability
The new 2018 Jeep Wrangler's body-on-frame design is bolstered by eight body mounts on two-door models and 10 on the four-door. A fully boxed frame utilizes high-strength steel in all critical areas and hydroformed sections of the front rails set a strong foundation to better handle the front suspension load. Galvanized frame components are utilized for improved corrosion protection. In total, five boxed cross members are used on Wrangler.
To protect critical components while on the trail, including the fuel tank, transfer case and automatic transmission oil pan, Wrangler employs four skid plates and bars. Rubicon models benefit from the use of heavy gauge tubular steel rock rails to curtail potential body damage inflicted while out on the trail.
New for 2018, a header bar now connects the A-pillars and stays in place even when the windshield is folded down. This allows the rearview mirror to remain in place with the windshield folded.
The use of lightweight, high-strength aluminum closures, including the doors, door hinges, hood, fender flares and magnesium swing gate help reduce weight and boost fuel economy.
Other ways the Jeep engineering team looked to reduce weight included using hollow track and stabilizer bars, aluminum engine mounts and steering gear, and a larger, lighter master cylinder.
For 2018, Wrangler continues to utilize the proven five-link coil suspension configuration. Wrangler's front suspension features a lateral control arm and four longitudinal control arms. Full width track bars made of forged steel control lateral movement of the axle with minimal angle change during suspension travel. The roll center height has been raised and the spring rates retuned to provide a comfortable ride when traveling around town.
The five-link rear suspension features two upper and two lower forged steel control arms for longitudinal control and a track bar for lateral axle control. The fuel tank is positioned in a central location and the control arms are located outside of the frame rails. The rear shocks are splayed (angled inboard at the top) to provide consistent damping.
The shocks have been retuned and demonstrate optimum balance between on-road handling and legendary off-road capability. Ride comfort, body roll control and handling is significantly improved with new shock tuning, hard points and body mount strategy.
On Wrangler Rubicon models, an electronic front sway bar disconnect is featured to provide additional wheel travel when the terrain calls for it.
An industry-leading approach angle of 44 degrees, breakover angle of 27.8 degrees, departure angle of 37 degrees and a ground clearance of 10.9 inches allows Wrangler to go anywhere.
Wrangler also benefits from up to 30 inches of water fording and up to 3,500 pounds of towing capacity with the available towing package.
All Wrangler models now feature electro-hydraulic power steering to deliver a more natural steering feel and improved fuel economy. The steering system's pump draws power from an electric motor that activates when it senses driver input and applies a variable amount of torque to assist the driver while steering. The electric motor works with an adaptive engine control unit (ECU) to monitor steering speed, steering wheel angle and vehicle speed. This allows for variable amounts of steering assistance to be applied, for example, when more is needed at low speeds maneuvering through a parking lot, or less when at highway speeds to enhance vehicle stability.
Wrangler's steering knuckles face outward into the wheel envelopes and reduce scrub radius. This allows for improved steering stability while braking and enhances steering input, including bump steer when going over uneven surfaces.
The roll center height has been raised on Wrangler and overall turning radius improved. Curb-to-curb turning circle is a snug 34.5 feet on Wrangler and 40.8 feet on Wrangler four-door models.
Both Wrangler two-door and four-door models feature electro-hydraulic power steering as standard equipment with a steering ratio of 17.4:1 for two-door models and 15.6:1 for the four-door. Wrangler's steering wheel can go from lock-to-lock in 3.5 turns for two-door models and 3.2 turns for four-door models.
Braking system and electronic stability control
The all-new 2018 Wrangler features larger brakes to improve stopping power when compared to the outgoing model. Stopping distance, brake noise, pedal feel and rotor life have all been improved as a result. A larger, lighter master cylinder, new full-time electric vacuum pump and redesigned pedals are also utilized to optimize braking performance.
Wrangler Sport models now feature 12.9 inch x .94 inch vented rotors while Sahara and Rubicon models use 12.9 inch x 1.1 inch vented rotors. Wrangler Sport features 1.9-inch twin piston, floating calipers up front and 1.8-inch single piston, floating calipers in back. Wrangler Sahara and Rubicon models feature two-inch twin piston, floating calipers in front and 1.9-inch single piston, floating calipers in the rear. The total swept front brake area on all Wrangler models is 75 square inches.
In back, Wrangler Sport models feature 12.9 inch x .47-inch rotors with cast iron, floating calipers while Sahara and Rubicon models use 13.4 inch x .55 inch rotors with cast iron, floating calipers. Total swept area for the rear brakes is 62 square inches on Sport and Sahara models and 66.8 square inches on Rubicon. All Wrangler models features a parking brake with a drum-in-hat design.
As part of Jeep's commitment to safety, four-wheel disc brakes and electronic stability control (ESC) are standard. The ESC system works with the anti-lock brake system (ABS) and includes sensors on all four wheels that are all monitored for wheel slip, particularly when deteriorating conditions in snow, ice, mud and wet pavement arise. If the system detects wheel slip, the brakes are applied to assist in keeping Wrangler on its desired path.
The ABS and ESC systems have been optimized for both on- and off-road conditions and demonstrated by the ESC system's ability to operate in three different modes - "full on," "full off" and "partial on."
Other systems that work under ESC include electronic roll mitigation, which uses sensors positioned at the center of the vehicle to detect yaw and apply the brakes when needed, and trailer-sway control, which reduces trailer sway and bolsters vehicle handling when demanding conditions, such as crosswinds, are detected. Brake traction control monitors and reduces wheel spin during hard acceleration from a stop or at low speeds in low traction situations by applying the brake to the wheel(s) that is slipping.
Jeep engineers optimized the 2018 Wrangler's structural design through the powertrain mounting system to isolate powertrain, wind and road noise. Both the 3.6-liter Pentastar V-6 and all-new 2.0-liter inline four-cylinder engine's noise are hardly noticeable while idling. On the 3.6-liter V-6, all necessary accessories are mounted right to the engine without the use of excess brackets. This allows all accessories, including the air conditioner compressor and alternator, to be anchored firmly, and are impermeable to vibration and noise. This clever design allows the 2018 Jeep Wrangler to boast improved interior sound quality.
The all-new Wrangler has undergone more than 3.9 million miles of testing - one of the highest totals ever for any FCA US vehicle. Extreme-weather testing occurred in various environments, including the scorching Arizona heat and blistering cold of Alaska, for weeks at a time. Wrangler was also subjected to global test miles in areas such as China, Brazil, India, Australasia and Italy. In addition to all laboratory and standardized tests, the all-new Wrangler traversed Northern Michigan mud and the Rubicon Trail.
All-new 2018 Jeep® Wrangler Combines Legendary 4x4 Systems With Advanced, Fuel-efficient Powertrains
The all-new Jeep® Wrangler will offer two different gasoline engines, one diesel engine and four different powertrain combinations.
A 3.0-liter V-6 EcoDiesel engine will be available on Wrangler 4-door models starting in 2019. The all-new 2.0-liter turbocharged inline four-cylinder engine with eTorque technology is optional while the proven, fuel-efficient 3.6-liter Pentastar V-6 engine is standard with Engine Stop-Start (ESS).
"The all-new Jeep Wrangler will offer three different engines, including a 3.0-liter EcoDiesel V-6, for vastly improved fuel efficiency," said Bob Lee, Vice President and Head of Engine, Powertrain and Electrified Propulsion Systems Engineering, FCA - North America. "Additionally, the eight-speed transmission is available to further enhance the drivability and efficiency of Jeep's off-road icon."
The icon of the Jeep brand, the new 2018 Wrangler, is the most capable sport-utility vehicle (SUV) ever, with two advanced available driveline systems offering unmatched capability no matter the conditions.
Wrangler Sport and Sahara models are equipped with the Command-Trac 4x4 system, featuring a part-time, two-speed transfer case with a 2.72:1 low-range gear ratio.
Rubicon models are equipped with the Rock-Trac 4x4 system, featuring a two-speed transfer case with a 4:1 low-range gear ratio, front and rear next-generation Dana 44 axles, Tru-Lok electric front- and rear-axle lockers, and electronic sway bar disconnect.
A new Selec-Trac two-speed transfer case with full-time four-wheel-drive (4WD) mode available on the Sahara model offers continuous power to the front and rear axles and is easy to use.
Available Trac-Lok limited-slip rear differential provides extra torque and grip during slippery, low-traction situations, such as driving over sand, gravel, snow or ice.
The Command-Trac 4x4 system with the NV241 transfer case helps get through any off-road obstruction and any weather condition. This 4x4 system can be engaged even while in motion - up to speeds of 55 miles per hour (mph) and features a 2.72:1 low range for rock crawling, and has the ability to be flat towed while in neutral. Wrangler Sport and Sahara models equipped with the standard six-speed manual transmission benefit from a 48.18:1 crawl ratio, while Sport and Sahara models with the eight-speed automatic transmission feature a 44.20:1 crawl ratio.
Standard on Wrangler Rubicon models, the Rock-Trac 4x4 system with an enhanced NV241 OR transfer case offers even more capability and a 4:1 low gear ratio. Wrangler Rubicon's off-road prowess is bolstered by all-new Tru-Lok electronic locking differentials and an electronic front sway-bar disconnect.
Wrangler Rubicon models equipped with the standard six-speed manual transmission boast an 84.2:1 crawl ratio. Rubicon models with the eight-speed automatic transmission feature a 77.2:1 crawl ratio.
New Selec-Trac two-speed transfer case with full-time 4WD mode
For the first time in Wrangler's history, a Selec-Trac two-speed transfer case with full-time 4WD and a low range is available on Sahara models. This new full-time two-speed transfer case is intuitive and allows the driver to set it and forget it while constantly sending power to the front and rear axles.
Three different engines - two gasoline and one diesel - will be available, while an all-new standard six-speed manual transmission and new optional eight-speed automatic transmission are available. The proven, fuel-efficient 3.6-liter Pentastar V-6 engine is standard with ESS.
2.0-liter turbocharged inline four-cylinder engine
The all-new 2.0-liter turbocharged inline four-cylinder engine with eTorque technology is rated a best-in-class 270 horsepower and 295 lb.-ft. of torque and mated to a new eight-speed automatic transmission. The 2.0-liter turbocharged inline four-cylinder engine's torque output surpasses that of the V-6 engine offered in Wrangler. An all-new eTorque system improves fuel economy, launch performance and driver comfort during start/stop operations.
The eTorque system's hybrid functions include auto stop/start, electric power assist, extended fuel shut-off, transmission shift management, intelligent battery charging and regenerative braking. Both the engine and fuel flow may be turned off during stops, coasting or when the engine is decelerating.
The all-new 2.0-liter I-4 engine features a twin-scroll, low-inertia turbocharger with an electronically actuated waste gate for exceptional responsiveness and performance, even while traversing over difficult terrain. The turbo is mounted directly to the cylinder head to improve durability. A dedicated cooling circuit lowers the temperature of the intake air, throttle body and turbocharger.
The 2.0-liter turbocharged I-4 engine is part of the Global Medium Engine architecture family and features Double Over Head Camshafts (DOHC), dual independent camshaft timing and a cooled exhaust gas recirculation (C-EGR) system. This is the first time that the combined use of a twin-scroll turbocharger, C-EGR system, Central Direct Injection and the independent liquid cooling intake of air, throttle body and turbo have been employed together. This combination of technologies enables the high levels of performance and reduces fuel consumption.
Direct injection, coupled with turbocharging, enables more efficient combustion and increased performance. The 2.0-liter I-4 engine's fuel pump supplies the engine's 2,900-psi high-pressure common-rail injection system. These high pressures produce better fuel atomization and allow for more precise fuel delivery than port fuel-injected systems, which in turn improves both performance and efficiency.
A variable displacement two-stage oil pump provides high oil pressure under high speed and load, but switches to a low-pressure mode for improved fuel economy during typical driving conditions. The piston cooling jet operation is managed by the two-stage oil pump to enhance fuel economy under normal driving conditions while improving durability under demanding, high-load engine operation. A large capacity oil cooler extends the oil change interval and ensures engine durability.
The cast aluminum alloy cylinder head features a central injector and high tumble intake ports. This combination provides increased charge motion and balanced airflow for improved fuel efficiency and performance. Cast-aluminum pistons with a 10:1 compression ratio have four valve pockets to accommodate the dual Variable Valve Timing (VVT) system. Each cylinder bore is fitted with gallery-mounted piston oil squirters to limit piston temperatures, reduce spark knock and increase piston durability.
The 2.0-liter I-4 engine features a low-pressure, sand cast-aluminum block with cast-in iron liners. The bore diameter is 84 mm and the stroke is 90 mm. Total displacement is 1,995 cc.
A water-cooled, integrated exhaust manifold helps reduce turbo inlet temperatures while providing increased engine reliability.
An inverted tooth primary chain drives both the intake and exhaust camshafts and minimizes noise. Camshafts are robotically assembled using hollow shafts and have polished cam journals to reduce weight and improve durability for start-stop engine operation. The use of hollow shafts provides a 3.5 lbs. weight reduction when compared to an equivalent solid shaft.
Select-fit main and rod bearings enable reduced clearances to help lower system oil demand and oil pumping effort. In addition, floating piston pins utilize Diamond Like Coating (DLC) for reduced friction.
The ignition system includes a high-energy ignition coil for better fuel efficiency and precious-metal spark plugs with iridium and platinum provide lasting durability. Located in the center of the cam cover, the spark plugs are easily accessible when service is required. Sodium-filled exhaust valves and plasma-coated piston rings also help extend the engine's life and bolster durability.
Engineered to provide a broad torque band with a focus on low-end torque, the 3.6-liter Pentastar V-6 engine is rated at 285 horsepower and 260 lb.-ft. of torque. ESS is now standard on all Wrangler models equipped with the 3.6-liter Pentastar V-6 engine. An all-new six-speed manual transmission is standard on all Wrangler models equipped with the 3.6-liter Pentastar V-6, and a new eight-speed automatic transmission is optional.
Known for its refinement, power, efficiency and adaptability, there are more than 5 million 3.6-liter V-6 Pentastar engines on the road today. The 2018 Jeep Wrangler benefits from the popular V-6 engine's low-range torque, which is needed when out on the trails or whenever the conditions call for it.
The 3.6-liter Pentastar V-6 engine employs a two-step variable-valve lift (VVL) cooled exhaust-gas circulation (EGR) and innovative weight-reduction strategies that boost the engine's efficiency and performance. The system is designed to remain mostly in low-lift mode until the customer demands more power, then it responds by switching to high-lift mode for improved combustion. The result is less overall pumping work, which on its own, helps improve fuel economy.
ESS, which is now standard equipment on all 3.6-liter Pentastar V-6 engines in Wrangler, is driven by a high-speed and high-durability starter, which reduces crank time for quicker restarts. With ESS, acceleration is always aligned with driver inputs. Passive accelerator application is met with measured throttle response; hard inputs trigger aggressive starts. There's no waiting for either.
If the driver chooses to forgo the benefits of ESS, the feature can be deactivated with the push of a button, then reactivated when the vehicle is restarted via the push button starter.
The 3.0-liter EcoDiesel engine will be available starting in 2019. Wrangler four-door models will offer a 3.0-liter EcoDiesel V-6 engine, rated at 260 horsepower and 442 lb.-ft. or torque, with ESS standard. A new eight-speed automatic transmission is standard and was designed to handle an increased torque output.
FCA US engineers adapted the engine - manufactured by FCA-owned V.M. Motori - to meet the NAFTA region's regulatory requirements.
The EcoDiesel V-6 engine implements new turbocharger technology with a low-friction bearing designed for low end and transient performance. The third-generation EcoDiesel V-6 engine also features low-friction pistons to improve fuel economy and reduce greenhouse gas emissions and an enhanced combustion system - new injector nozzle, piston bowl and glow plug with integrated combustion pressure sensor to optimize combustion.
The EcoDiesel's fuel pump supplies the engine's 2,000-bar (29,000-psi) high-pressure common-rail injection system.
The engine also benefits from MultiJet 2 technology, which enables Injection Rate-Shaping - fuel injection that is modulated to mitigate noise and improve low-speed throttle response, while reducing fuel consumption.
The system's high-dispersion nozzles and advanced-technology servovalve can accommodate up to seven fuel-injection events per cylinder cycle.
The new 2018 Jeep Wrangler offers the FCA US-manufactured TorqueFlite eight-speed automatic transmission, enabling the vehicle to optimize engine output while on the trails or enjoying smooth, efficient power delivery at highway speeds. The eight-speed automatic is available on all Jeep Wrangler models.
Wrangler four-door models equipped with the 3.0-liter V-6 EcoDiesel engine utilizes an even more robust version of the eight-speed automatic transmission to handle the elevated torque output.
As in other FCA US vehicles, the Wrangler's eight-speed automatic transmission offers a responsive driving experience. Whether commuting during the week or rock crawling on the weekend, customers will enjoy a smooth, linear power delivery and improved fuel efficiency.
A unique set of two overdrive ratios improve highway fuel economy and reduce overall noise, vibration and harshness (NVH) levels.
The fully electronic, eight-speed automatic transmission features the on-the-fly shift-map changing with Auto Stick manual shift capability.
The sophisticated transmission software relies on many input parameters to determine the appropriate driving conditions and adjusts shift pattern in response to these driving conditions to offer the best possible fuel economy and drivability balance. The result is automatic shifting ideally attuned to the performance requirements of almost any driving demand.
The transmission's gear ratios afford the right response at the right time, from crawling over obstructions on the trail to smooth power delivery at highway speeds, a product of smaller ratio steps between the gears.
The Jeep Wrangler's eight-speed automatic transmission provides a more responsive driving experience with quicker acceleration and smoother shifting. The wide ratio spread delivers an aggressive first gear ratio of 4.71 for low-end performance and small gear ratio steps provide smooth transitions from gear-to-gear.
However, a Jeep SUV isn't a Jeep SUV unless it delivers superior off-road performance. Uniquely suited to the requirements of the Wrangler Rubicon model, the eight-speed automatic transmission delivers a 77.2:1 crawl ratio setting. The improved 4x4 performance benefits from a 4.71 first-gear ratio coupled with a 4.1:1 final drive to deliver unmatched capability.
All-new, fun-to-drive six-speed manual transmission
New 2018 Jeep Wrangler models are equipped with the standard six-speed manual transmission. This transmission features a unique design that features new gear ratios for improved crawl ratio performance, a new gear pattern, and a cable-operated shift design that eliminates movement and improves sound isolation.
The revised shift pattern now features improved shift accuracy, a more comfortable shifting position and 50 percent shorter shifter throws than that of the outgoing Wrangler model.
A 4.41 ratio spread offers improved fuel efficiency at faster speeds and delivers quick acceleration with smooth, precise shift quality.
