Jeep Grand Cherokee Mileage and Engine Specs

The most important thing to consider when it comes to the 2020 Grand Cherokee MPG is the engine. This capable vehicle gives you four to choose from, each one more powerful than the last.

However, they differ greatly in terms of gas mileage:

  • 3.6L Pentastar® V6: 18 city/25 highway MPG
  • 5.7L HEMI® V8: 14 city/21 highway MPG
  • 6.4L SRT® V8: 13 city/19 highway MPG
  • 6.2L supercharged V8: 11 city/17 highway MPG

As you can see, the 3.6L Pentastar® V6 engine gets you the highest fuel economy, at an EPA-estimated 18 city/25 highway MPG when equipped with 4WD. With FWD, the same engine gets an EPA-estimated efficiency of 19 city/26 highway MPG.

So, if your focus is on fuel economy, then you'll probably prefer the 3.6L V6 engine, which produces an impressive 295 horsepower. It can also tow a maximum of 6,200 pounds with 4WD and 3,500 pounds with FWD.

If that's not enough power for you, however, you can upgrade to any of the V8 engines. They generate 360, 475, and 707 horsepower, respectively. These engines can tow up to 7,200 pounds and only come with 4WD.

Drivetrain and Handling Capabilities

We've talked a lot about the drivetrain options for the 2020 Jeep Grand Cherokee and the MPG differences between FWD and 4WD. Now, let's take some time to discuss the Jeep 4WD systems that are available for the Grand Cherokee.

These are:

  • Quadra-Drive® II
  • Quadra-Trac II®
  • Quadra-Trac I®
  • Quadra-Trac® Active on Demand 4WD

These are Trail Rated® systems that are meant for the great outdoors. They feature handling capabilities designed to keep you moving forward, even when facing challenging terrain.

The 4WD systems also come standard with the Selec-Terrain® Traction Management System. This gives you selectable drive modes, so you can customize your handling for your exact conditions. Drive modes are: Auto, Snow, Sand, Mud, and available Rock.

4WD comes standard for the V8 engines and is available for the V6 engine. System availability varies by trim level and engine, so ask the team at our dealership about what options will work best for you.
