To cope with all that weight, the Jeep Grand Wagoneer L’s engine needs to have enough power. To that end, the new Hurricane 3.0-liter inline-six twin-turbo engine comes only in high-output guise in the Grand Wagoneer L. It produces a strong 510 horsepower and 500 lb-ft of torque. Those numbers are better than what the 6.4-liter naturally-aspirated V8 in the regular Grand Wagoneer can manage, and brings the Grand Wagoneer L into better contention with the Lincoln Navigator which has a twin-turbo V6. Cadillac has the option of a torquey and efficient turbodiesel, so all of these gargantuan SUVs have moved on from exclusively big V8s.
Although 0-60 times aren’t of great importance here, what is worth noting are the fuel economy estimates of 14/19/16 mpg city/highway/combined as published by Jeep. That’s 1 mpg better overall than the smaller, lighter, and less powerful Grand Wagoneer 4×4 with the 6.4-liter V8.
Paired with the Hurricane engine is an eight-speed automatic transmission and there are three available 4×4 systems: Quadra-Trac I, Quadra-Trac II, and Quadra-Drive II. An air suspension with semi-active damping is standard on the Grand Wagoneer L. Impressively, the Grand Wagoneer L can tow up to 9,450 lbs.
