Watch out Chevy Suburban! Step aside Lincoln Navigator and Cadillac Escalade – the new 2023 Jeep Wagoneer L and Grand Wagoneer L are here with an aim to rule the giant and luxurious SUV market. Here is the world debut with all the details from the 2022 NY Auto Show.

As we report just a few days ago, Jeep is having success with the sales of the 2022 Wagoneer and Grand Wagoneer SUVs. When putting the two together the company sold over 10,000 big SUVs in Q1 2022. This is more than all Ford Expedition U.S. sales over the same period. Jeep hopes to build on this success by making the Wagoneer SUVs bigger, more powerful, and more efficient. How is this possible? Let’s dig in.


In order to create the long-wheelbase 2023 Wagoneer L and Grand Wagoneer L, Jeep stretched the wheelbase by about seven (7) inches to a total of 130 inches. The overall length grows by 12 inches to a total of 226.7 inches. The total length is exactly one inch longer than a new 2022 Chevy Suburban (although the big GM SUVs ride on a longer 134.1-inch wheelbase).

This stretching exercise creates a class-leading 44.2 cu-ft cargo volume behind the third row. The overall passenger volume is a cavernous and class-leading 179.3 cu-ft. These long SUVs are offered in either 7 or 8-passenger configurations. Sorry – no old-school 9-person configurations here.


While the V8 engine options will remain for the 2022 model year, the new 2023 Wagoneer L and Grand Wagoneer L model will offer the new 3.0-liter straight-six twin-turbo engine options. The 2023 Wagoneer L will offer a standard 3.0L Hurricane Turbo I6 with a rating of 420 horsepower @ 5,200 rpm and 468 lb-ft of torque @ 3,500 rpm. Yep, this new “standard” powerplant produces more power and torque than GM’s premium 6.2L V8.

When you move up to the more luxurious 2023 Grand Wagoneer L, you can choose a high-output Hurrican I6 engine with 510 horsepower @ 5,700 rpm and 500 lb-ft of torque @ 3,500 rpm. While the standard turbo engine can be run on regular 87-octane fuel, the high-output version requires premium 91-octane juice.


Jeep states the following EPA estimates for the new 2023 models.

  • 2023 Jeep Wagoneer S.O. 2WD: 17/23/19 MPG
  • 2023 Jeep Wagoneer S.O. 4×4: 16/22/19 MPG
  • 2023 Jeep Graand Wagonner H.O. 4×4: 14/19/16 MPG

Here is how these new 3.0L Hurricane I6 MPG numbers compare to the V8 Jeeps, Chevy Suburban, and the turbocharged Ford Expedition. The new Hurricane engine is estimated to return 1 to 2 MPG better numbers than comparable V8 models.

Jeep says the new I6 turbo-powered Wagoneer SUVs will tow up to 10,000 lbs, which is equivalent to their V8-powered counterparts. The 10,000 lbs tow rating is still class-cleading.

You can order a 2022 Jeep Grand Wagoneer with a new Hurrican H.O. engine right now. This engine option is expected to cost $2,000 over the current 6.4L gas V8. We will have to wait a bit longer for the 2023 long-wheelbase models.

Here is a 6.4L V8-powered Grand Wagoneer showing off its power and capability while towing an 8,100 lbs trailer.
