Understanding the Core: 2018 Jeep Grand Cherokee Configurations Unpacked
The 2018 Jeep Grand Cherokee is a versatile SUV, renowned for blending luxury, comfort, and genuine off-road capability. It offers a wide array of options, making it suitable for everyone from the suburban parent to the hardcore overlander. Understanding these options is key to appreciating what your Grand Cherokee can do.

The Grand Cherokee Philosophy: Blending Comfort and Capability
Jeep has always aimed to create vehicles that can handle tough terrain without sacrificing daily drivability. The 2018 Grand Cherokee embodies this philosophy perfectly. You get a comfortable interior, modern technology, and robust engineering ready for adventure.
This balance is why so many enthusiasts and everyday drivers gravitate towards the Grand Cherokee. It’s not just an SUV; it’s a lifestyle vehicle that adapts to your needs.
Trim Levels: Finding Your Flavor of Grand Cherokee
The 2018 Grand Cherokee was available in a generous number of trim levels, each designed to appeal to a different buyer. Knowing these distinctions is crucial when considering your next purchase or when planning modifications for your current vehicle.
Laredo: The Accessible Entry Point
The Laredo is the base trim, but don’t let that fool you. It still offers a respectable level of comfort and capability. It typically comes with the 3.6L Pentastar V6 engine and can be equipped with either 2WD or Jeep’s Quadra-Trac I 4×4 system. Standard features include a Uconnect 4 system with a 7-inch display, dual-zone automatic climate control, and keyless entry.
This trim is a great starting point for DIY enthusiasts looking to build their own custom rig without paying for features they’ll replace anyway. It’s also an excellent daily driver.
Limited: Stepping Up in Comfort
Moving up, the Limited trim adds more creature comforts and technological enhancements. You’ll often find leather upholstery, heated front and rear seats, a heated steering wheel, and an 8.4-inch Uconnect touchscreen with navigation as optional or standard. The 5.7L HEMI V8 becomes an option here, alongside the standard V6.
The Limited is a popular choice for families and those who want a bit more luxury without venturing into the premium price points. It balances comfort with solid capability.
Trailhawk: The Off-Road Champion
For the true off-roaders, the Trailhawk is where the 2018 Jeep Grand Cherokee configurations really shine. This trim is “Trail Rated” and comes standard with specific hardware designed for tackling tough trails. Key features include:
- Quadra-Drive II 4×4 system with an electronic limited-slip rear differential.
- Quadra-Lift air suspension, offering increased ground clearance.
- Skid plates for underbody protection.

- Selec-Speed Control with Hill Ascent and Hill Descent Control.
If you plan on hitting serious trails, the Trailhawk provides a fantastic factory-tuned platform. You still get a comfortable interior, but the focus is clearly on capability.
Overland: Premium Refinement
The Overland trim bridges the gap between rugged capability and luxury. It incorporates many of the Trailhawk’s off-road features, like the Quadra-Lift air suspension and Selec-Terrain system, but wraps them in a more upscale package. You’ll find premium leather, ventilated front seats, a panoramic sunroof, and advanced safety features.
This trim is for those who want to experience both worlds – a comfortable, luxurious daily driver that can still confidently venture off the beaten path.
Summit: The Pinnacle of Luxury
The Summit is the most luxurious non-performance trim. It offers an even more refined interior with premium NaturaPlus leather, a 19-speaker Harman Kardon audio system, and a full suite of advanced safety technologies. While still capable, its primary focus is on passenger comfort and high-end features.
If you prioritize a plush ride and top-tier amenities, the Summit delivers without compromise.
SRT: Performance Prowess
Stepping into the performance trims, the SRT (Street & Racing Technology) is built for speed. It features a potent 6.4L HEMI V8 engine, performance-tuned suspension, Brembo brakes, and unique exterior styling. While not an off-roader, its all-wheel-drive system provides impressive grip on pavement.
This configuration is for the enthusiast who wants SUV practicality with sports car acceleration.
Trackhawk: Unrivaled Power
The ultimate performance Grand Cherokee, the Trackhawk, boasts a supercharged 6.2L HEMI V8 engine, shared with the Hellcat. It’s the fastest SUV ever produced at its launch, offering breathtaking acceleration and a unique presence. Like the SRT, it prioritizes on-road performance and comes with heavy-duty components to manage its immense power.
If you crave raw power and blistering speed from your SUV, the Trackhawk is in a league of its own.
Powertrain Options: Powering Your Adventure
The heart of any vehicle is its engine, and the 2018 Grand Cherokee offered a range of powerful options. Your engine choice heavily influences performance, fuel economy, and towing capacity.
3.6L Pentastar V6: The Balanced Choice
Standard on most trims (Laredo, Limited, Trailhawk, Overland, Summit), the 3.6-liter Pentastar V6 engine is a workhorse. It produces 295 horsepower and 260 lb-ft of torque, providing a good balance of power and fuel efficiency. This engine is more than capable for daily driving, light towing, and most off-road scenarios.
Many DIYers appreciate its reliability and the wealth of aftermarket support available for minor performance enhancements or maintenance.
5.7L HEMI V8: Classic American Muscle
Optional on Limited, Trailhawk, Overland, and Summit trims, the 5.7-liter HEMI V8 delivers 360 horsepower and 390 lb-ft of torque. This engine significantly boosts towing capacity (up to 7,200 lbs) and provides a more authoritative driving experience. It’s a favorite among those who tow trailers or simply enjoy the rumble of a V8.
For heavier hauling or a more responsive throttle, the HEMI is a strong contender. Just remember, it drinks more fuel.
6.4L SRT HEMI V8: Performance Street Machine
Exclusive to the SRT trim, this naturally aspirated 6.4-liter HEMI V8 pumps out 475 horsepower and 470 lb-ft of torque. It’s designed for high-performance driving, offering exhilarating acceleration and a distinct exhaust note. While not for off-roading, it transforms the Grand Cherokee into a formidable street machine.
Maintaining this engine requires attention to detail, especially regarding oil changes and cooling systems, to preserve its performance.
6.2L Supercharged HEMI V8: The Trackhawk’s Roar
The beastly 6.2-liter supercharged HEMI V8, found only in the Trackhawk, delivers a mind-blowing 707 horsepower and 645 lb-ft of torque. This engine is purely about extreme performance, launching the SUV from 0-60 mph in a blistering 3.5 seconds. It’s an engineering marvel, but it demands premium fuel and diligent maintenance.
If you own a Trackhawk, be prepared for specialized service and higher running costs – the smiles per gallon are off the charts, though!
The 8-Speed Automatic Transmission
All 2018 Grand Cherokee engines are paired with an excellent 8-speed automatic transmission. This transmission provides smooth shifts, optimizes fuel efficiency, and handles the varying power outputs effectively. It also features a manual shift mode for more driver control.
Proper transmission fluid maintenance is crucial for longevity, especially if you tow or engage in heavy off-roading.
Drivetrain Systems: Conquering Any Terrain
Jeep’s 4×4 systems are legendary, and the 2018 Grand Cherokee offers several sophisticated options to ensure you can tackle diverse terrains. These systems are a core component of the 2018 Jeep Grand Cherokee configurations for off-road enthusiasts.
Quadra-Trac I: Full-Time Simplicity
Standard on some 4×4 Laredo models, Quadra-Trac I is a full-time, single-speed 4×4 system. It uses a transfer case to continuously send power to all four wheels, splitting torque 48/52 front/rear. It’s completely automatic and requires no driver input, making it great for light snow, rain, or unpaved roads. There’s no low range gearing.
This system is ideal for those who need all-weather traction without complex controls.
Quadra-Trac II: Enhanced Capability with Low Range
Available on Limited, Overland, and Summit trims, Quadra-Trac II is a more advanced system. It features a two-speed transfer case, allowing for a 4-Low gear ratio (2.72:1) for serious off-roading. It uses a network of sensors to detect tire slip and can proactively redistribute up to 100% of available torque to the axle with the most traction.
This is a solid choice for most weekend warriors and provides excellent capability on moderate trails.
Quadra-Drive II: The Ultimate Off-Road System
Standard on the Trailhawk and optional on Overland/Summit with the HEMI V8, Quadra-Drive II is Jeep’s most capable 4×4 system for the Grand Cherokee. It builds on Quadra-Trac II by adding an electronic limited-slip differential (ELSD) at the rear axle. This ELSD can instantly detect slip and send all available torque to a single wheel if needed, significantly enhancing traction.
For serious rock crawling, deep mud, or challenging uneven terrain, Quadra-Drive II is your best friend. It truly earns the “Trail Rated” badge.
Selec-Terrain Traction Management System
Most 4×4 Grand Cherokees come with the Selec-Terrain system, which works in conjunction with Quadra-Trac II or Quadra-Drive II. This system allows the driver to select different modes (Auto, Snow, Sport, Sand/Mud, Rock) that optimize the vehicle’s performance by adjusting:
- Throttle response
- Transmission shift points
- Transfer case operation
- Traction control
- Electronic Stability Control (ESC)
Using the correct Selec-Terrain mode can make a significant difference in handling challenging conditions safely. Always assess the terrain and select the appropriate mode before proceeding.
Quadra-Lift Air Suspension: Variable Ride Height
Optional or standard on Trailhawk, Overland, and Summit trims, Quadra-Lift air suspension allows the driver to adjust the vehicle’s ride height. This is incredibly useful for off-roading, as it can increase ground clearance by up to 4.1 inches from normal ride height, providing up to 10.8 inches of total ground clearance on the Trailhawk.
It also offers an “Aero” mode for improved highway fuel efficiency and an “Entry/Exit” mode for easier access. For DIYers, understanding how to calibrate and troubleshoot this system is vital.
Key Features & Packages: Elevating Your Ride
Beyond the core trims and powertrains, several features and optional packages can significantly alter a Grand Cherokee’s character and capability. These are important considerations when looking at various 2018 Jeep Grand Cherokee configurations.
Uconnect Infotainment Systems
The 2018 Grand Cherokee came with either a 7-inch or 8.4-inch Uconnect touchscreen system. Both offer Apple CarPlay and Android Auto integration, Bluetooth, and various media inputs. The larger 8.4-inch system often includes navigation and more advanced features.
These systems are generally user-friendly, but keeping the software updated can prevent glitches and enhance functionality.
Advanced Safety and Driver-Assist Technologies
Many 2018 models were available with advanced safety features, especially in higher trims or specific packages. These include:
- Blind-Spot Monitoring with Rear Cross-Path Detection
- Forward Collision Warning with Active Braking
- LaneSense Lane Departure Warning with Lane Keep Assist
- Adaptive Cruise Control with Stop and Go
- Parallel and Perpendicular Park Assist
These systems enhance safety and convenience, particularly on long drives or in heavy traffic. Always understand how they work and their limitations.
Luxury and Comfort Packages
Higher trims like Overland and Summit offer numerous luxury features, such as ventilated seats, premium leather, wood trim, dual-pane panoramic sunroofs, and advanced sound systems (like the Harman Kardon on Summit). These packages transform the interior into a truly premium space.
While great for daily comfort, remember that these additions can increase vehicle weight and complexity.
Off-Road & Towing Considerations for Your 2018 Grand Cherokee
For many FatBoysOffroad readers, the ultimate question is: how well can it off-road or tow? The configuration you choose makes all the difference.
Maximizing Off-Road Capability
If off-roading is your priority, focus on models with:
- Trailhawk trim: It’s purpose-built with Quadra-Drive II, Quadra-Lift, skid plates, and better approach/departure angles.
- Quadra-Drive II 4×4 system: The electronic limited-slip differential is a game-changer for traction.
- Quadra-Lift air suspension: Adjustable ground clearance is invaluable for clearing obstacles.
- Off-road tires: Even a stock Trailhawk can benefit from upgrading to more aggressive all-terrain or mud-terrain tires.
- Skid plates: Essential for protecting vital underbody components from rocks and debris.
When you’re out on the trail, always remember to air down your tires for better traction and a smoother ride. Carry recovery gear like a shovel, recovery straps, and a first-aid kit. If you’re tackling challenging terrain, consider going with another experienced off-roader.
Towing Capacity and Setup
The 2018 Grand Cherokee is a capable tow vehicle, especially with the HEMI V8. Here’s what to look for:
- 5.7L HEMI V8: Max towing capacity up to 7,200 lbs.
- 3.6L Pentastar V6: Max towing capacity up to 6,200 lbs.
- Trailer Tow Group IV: This package typically includes a Class IV receiver hitch, 7- and 4-pin wiring harness, heavy-duty engine cooling, and a full-size spare tire. It’s a must-have for serious towing.
- Integrated Trailer Brake Controller: While not always factory-installed, this is a crucial aftermarket addition for safely towing heavier loads.
Always check your specific vehicle’s owner’s manual for exact towing capacities and tongue weight limits. Never exceed these limits. When towing, ensure your trailer is properly loaded and balanced, and conduct a thorough pre-trip inspection of lights, tires, and connections. Drive cautiously and allow for extra stopping distance.
