Fuel economy for the 2022 Jeep Grand Wagoneer is out (h / t CarScoops), and as you would expect, the results are not pretty. Since we are talking about the Grand Wagoneer, this means that we are exclusively dealing with the 6.4-liter V8. This engine is not known for its great fuel economy in its Charger and Challenger Scat Pack applications, so we are not surprised to learn that it is still thirsty in the VU. The standard Wagoneer offers a 5.7-liter V8, but fuel economy for this truck is not over yet.
Its most fuel-efficient form is when the truck is paired with rear-wheel drive. This model returns 13 mpg of the city, 19 mpg of highway, and 15 mpg combined. Neither the city nor the highway number changes when you select the four-wheel drive, but the highway number decreases from one to 18 mpg. Unfortunately for Jeep, these numbers put the Grand Wagoneer at the bottom of its class for fuel economy.
None of the full-size SUVs you can buy yield particularly stellar mpg with their large V8 engine options, but the Grand Wagoneer is actually the worst compared to its main competition. Before we start comparing, we note that all comparisons are effective using the versions in four different ways.
The Cadillac Escalade with its 6.2-liter V8 beats the Jeep by 1 mpg combined. A Lincoln Navigator with its 3.5-liter twin-turbo V6 ups that are supplied by 1 mpg to 17 mpg combined. At the end of the day, you can enjoy 1,050 less at the pump for a navigator and 250 L less per year with an escalade (6.2 L). The Duramax diesel from the Escalade, however, deserves a mention here. You will receive an excellent 22 mpg combined and you will receive a year in fuel compared to a Large Wagoneer.
The other theoretical competitors to high mpg Vienna from Germany. They’re not as big as the Grand Wagoneer, but the Mercedes-Benz GLS 580 and BMW X7 M50i both offer three ranges of roomy seats and V8 engines. The Mercedes returns a respectable 18 mpg, and the BWW offers 17 mpg combined. Highway fuel economy is where these two performances are best, as they are both rated for 21 mpg on the highway.
The other end of the spectrum brings us to Japan with the Lexus LX 570 and Infiniti QX80. The QX80 returns a Large Wagoneer-corresponding to 15 mpg combined, but the Lexus is the worst of all at 14 mpg combined.
