Right on the heels of launching a new model, the Jeep Wagoneer L and Grand Wagoneer L expand on this new luxury SUV, literally. Plus, there is a new Hurricane engine under the hood.

The Wagoneer and Grand Wagoneer are the first body-on-frame, three-row SUVs from the newly formed Stellantis and from the old Chrysler name in decades. They combine the off-road equipment from the Jeep lineup with refined interiors. Now they are going to get larger and more fuel efficient.

Here are the 5 key things you need to know about these two SUVs with an “L” suffix.

Longer length and wheelbase

The Jeep Wagoneer L and Grand Wagoneer L will add 12 inches to the overall length (226.7 inches), pushing it to an inch longer than a Chevrolet Suburban — the king of big SUVs.

This additional length flows nicely into the body lines and the pushes the wheelbase, measuring from front wheels to rear wheels, out 7 inches to a total of 130 inches.

With this length, you’ll have more room in the cabin and, more importantly, more cargo room behind the third row, allowing you to carry even more stuff like camping gear, suitcases, golf clubs, etc.

Bring on the Hurricanes!

As I noted during my first drive of the Wagoneer and Grand Wagoneer, there seemed to be an opportunity to bring in a more efficient powertrain with occasional towing capability. These full-size SUVs are pretty thirsty trying to be good at both carrying people and towing as well. Not everyone needs this dual capability, and offering a different powertrain seemed like a no brainer.

What I didn’t know was that engine was already on the way.

For the 2023 model year, the Jeep Wagoneer L and Grand Wagoneer L will offer a new standard 3.0-liter inline 6-cylinder twin-turbo engine called the Hurricane with two different horsepower and torque ratings.

The Wagoneer L gets the standard output Hurricane producing 420 horsepower and 468 pound-feet of torque. While the Grand Wagoneer L will get the higher-output 510 engine with, you guessed it, 510 horsepower and 500 pound-feet of torque.

Both engines return an estimated 1 to 2 MPG combined-rating improvement compared with the existing V-8 engines. EPA estimates (city/highway/combined) for the 3.0-liter equipped Wagoneer L and Grand Wagoneer L are as follows:

  • Wagoneer L: 4X2: 17/23/19 MPG
  • Wagoneer L 4X4: 16/22/19 MPG
  • Grand Wagoneer L: 14/19/16 MPG

This engine should offer a better driving experience being inherently balanced and having more power and a 15% reduction in emissions.

The only downside: The 510 engine calls for 91 octane fuel, and this premium octane level is required.

New Carbide edition

Another new item for the 2023 Jeep Wagoneer L is the Carbide edition.

This special edition will feature gloss black wheels, black onyx grille rings with gloss black grille texture, gloss black mirror and headlamp inserts, “technical hydrographic instrument panel trim” and doors with global black seats according to a Stellantis press release.

Basically, it is a blacked out version of the Wagoneer L with a few unique touches.

The bottom line on the Jeep Wagoneer L and Grand Wagoneer L

After just putting its first full-size SUV on the market, these longer SUVs are going to fill a void by going after the well-known Chevy Suburban. For far too long, consumers haven’t had many other worthy options on the market, and now they do. Competition is a beautiful thing for consumers.
