the 2023 model year will see stellantis’ new twin-turbocharged 3.0-liter inline-six, named hurricane, introduced across the wagoneer and grand wagoneer lineup. but before that happens, a limited run of 2022 grand wagoneers will be sold with the high-output version of the hurricane, producing 510 horsepower and 500 pound-feet of torque. now the epa has released fuel-economy ratings for this new powertrain setup, and the high-output hurricane beats the grand wagoneer’s 6.4-liter v-8 when it comes to efficiency.
the epa rates the all-wheel-drive, six-cylinder 2022 grand wagoneer at 14 mpg city and 20 mpg highway, for 17 mpg combined. this is notably better than the 6.4-liter v-8, which returns 13 mpg city and 18 mpg highway for 15 mpg combined. starting in 2023, the hurricane will also be available in the wagoneer, which is currently fitted with a 5.7-liter v-8. with all-wheel-drive, the 5.7-liter nearly matches the grand wagoneer six-pot’s fuel economy with 15 mpg city, 20 mpg highway, and 17 mpg combined. it’s worth noting, however, that this comparison is with the high-output hurricane, and the 420-hp standard-output version that will also be available next year could return better figures. the wagoneer is also offered with rear-wheel drive, and the six-cylinder will likely return even better fuel economy with that setup, regardless of power output.
the six-cylinder will be the only engine available in the new-for-2023 long-wheelbase grand wagoneer l and wagoneer l. the extra length and weight will likely knock the fuel economy down a tad. for now, the new inline-six is only available on the 2022 grand wagoneer in the top specification, making it the more powerful engine in the lineup. it costs an additional $2000 over the 471-hp v-8, and dealerships are currently accepting orders.
