All-Aluminum Engine and Light Metals in 2021 Jeep Grand Cherokee L

© by Stellantis North America

The 2021 Jeep Grand Cherokee (JGC) L is here, and even though it is presented in the full-size SUV segment (with three rows of seats for the first time ever), magnesium and aluminum in the car’s construction help keep it’s curb weight lower than most traditional SUVs. A multitude of improvements have been made to the latest Grand Cherokee L 2021 models (Summit and Overland) to optimize ride, handling, and noise control, while also reducing weight and improving fuel economy.

The JGC L is powered by the trusted all-aluminum 3.6-liter V6 engine (standard) with 290 hp and 348 Nm of torque. Drivers who want more power can opt for the 5.7 liter V8, with 357 hp and 528 Nm of torque delivered over a broad power band and class-leading towing capacity of up to 3,265 kg. The V8, with a foundation of a cast-iron block and aluminum cylinder heads, delivers performance and efficiency with VVT and Fuel Saver Technology (cylinder deactivation).

A new unibody design along with three available 4×4 systems, an available Quadra-Lift air suspension and standard Selec-Terrain traction management system improve on the Grand Cherokee’s 4×4 capability. The all-new architecture and sculpted aerodynamic body style combine to improve vehicle performance, safety and reliability, while significantly reducing vehicle weight, noise, vibration and harshness.

Metals in the Making

The use of lightweight, high-strength aluminum closures, including the hood and tailgate, help reduce weight and boost fuel economy. The Jeep engineering team reduced weight by mounting the axle directly to the engine, along with a solid-mounted aluminum front cradle, aluminum engine mounts and steering gear, a magnesium cross-car beam, aluminum shock towers, and an all-new electronic master brake booster system. The Grand Cherokee L body structure also used the latest grades of Generation 3 steel.

Luxury Revamps

The 2021 Jeep Grand Cherokee is no stranger to advanced technology when it comes to comfort and entertainment as well, the new jeep features:

  • Standard 10-inch display screens across the instrument panel, including a frameless digital gauge cluster and touchscreen radio, all-new LED lighting with ambient features, driver and front passenger seat massage and personalized climate zones
  • Hand-wrapped, quilted Palermo leather, open-pore Waxed Walnut wood, 21-inch wheels (with aluminum rims!) and standard premium amenities
  • More than 110 advanced safety and security features, including L2 driver-assist systems with hands-on automated driving, along with 360-degree surround view and night vision cameras; advanced hands-free L2 automated driving system will be available in late 2021 on the 2022 Grand Cherokee L
  • Next-generation technologies, including the most advanced Uconnect system ever with wireless Apple CarPlay and Android Auto, windshield Head-up Display (HUD), digital rearview mirror, frameless digital cluster, rear seat monitoring camera, and an exclusive and premium 950-watt, 19-speaker McIntosh audio system

“The new 2021 Jeep Grand Cherokee is crafted to exceed expectations and do what no other SUV can do: deliver legendary Jeep 4×4 off-road capability blended with superior on-road manners,” said Christian Meunier, Global President of Jeep Brand – FCA. “It is built on an all-new architecture and wrapped in a stunning new design that honors its iconic Jeep design heritage, while also extending to accommodate a third row to meet the growing needs of our Jeep customers who have asked for more space and functionality. The Grand Cherokee L truly stands out in its segment and continues to raise the bar in capability, performance and luxury, while also breaking new ground in versatility and functionality.”
