2023 Jeep Grand Wagoneer joins the lineup. Its wheelbase is seven inches longer than the standard Wagoneer, and it’s a foot longer overall. These extensions help to significantly increase the cargo space behind the three rows of seats. Under the hood, the long-wheelbase model features Stellantis’ new Hurricane engine, which is a twin-turbocharged 3.0-liter inline-six that develops 510 horsepower and 500 pound-feet of torque. Although standard on the stretched Grand Wagoneer L, a 471-hp 6.4-liter V8 is still available on the base version of the regular Grand Wagoneer.
