For the average owner, this V6 is more than capable. It’s responsive, relatively quiet, and offers a good blend for city driving and longer trips.

The Optional Powerhouse: 5.7L HEMI V8 Engine

For those who demand more muscle, the 5.7-liter HEMI V8 is the upgrade you’ll want. This engine transforms the Grand Cherokee L Limited into a towing and performance beast.

Horsepower: Cranks out a significant 357 hp, giving you serious acceleration and passing power.

Drivetrain & Suspension: Off-Road Readiness and Ride Comfort

Jeep’s reputation for off-road capability is legendary, and the Grand Cherokee L Limited continues this tradition, even in its longer, more luxurious form. Understanding its drivetrain and suspension is vital for anyone planning to venture off the beaten path.

Quadra-Trac I, Quadra-Trac II, and Quadra-Drive II

The 2021 Grand Cherokee L Limited offers various 4×4 systems, ensuring you can tackle different terrains with confidence. These systems are a core part of the 2021 Jeep Grand Cherokee L Limited specs.

Quadra-Trac I: A full-time 4×4 system that requires no input from the driver. It’s great for everyday traction in varying conditions like rain or light snow.
Quadra-Trac II: This system adds a two-speed transfer case and allows for active torque distribution. It can send up to 100% of torque to the axle with the most traction, making it superior for moderate off-roading.
Quadra-Drive II: The ultimate off-road system, featuring a two-speed transfer case and electronic limited-slip differentials (ELSD) at both the front and rear axles. This system provides unparalleled traction by sending power to individual wheels as needed, making serious rock crawling or mudding achievable.

For DIY mechanics, understanding which system your vehicle has is crucial for troubleshooting drivetrain issues or planning off-road upgrades. Always consult your owner’s manual for specific operational details.

Quadra-Lift Air Suspension System

The optional Quadra-Lift air suspension system is a game-changer for both comfort and capability. This system allows you to adjust the vehicle’s ride height, offering several benefits:

Entry/Exit Mode: Lowers the vehicle for easier passenger entry and cargo loading.
Aero Mode: Automatically lowers the vehicle at highway speeds to improve aerodynamics and fuel efficiency.
Off-Road 1 & 2 Modes: Raises the vehicle to increase ground clearance, allowing you to clear obstacles more easily.

Cargo Volume: With all seats up, you get decent cargo space, but fold down the second and third rows, and you unlock a cavernous area for gear, tools, or camping equipment.

Measuring the interior space yourself with a tape measure can give you a better idea of how your specific gear or family will fit.

Popular Performance Upgrades

If you’re looking to boost your Jeep’s capabilities, consider these common modifications:
