Stellantis’ new twin-turbocharged 3.0-liter inline-six, dubbed Hurricane, will debut throughout the Wagoneer and Grand Wagoneer lineups in 2023.

However, a limited number of 2022 Grand Wagoneers will be equipped with the high-output Hurricane, which delivers 510 Hp & 500 pound-feet of torque.

The EPA has now issued fuel-economy numbers for this new powertrain combination, and the high-output Hurricane outperforms the Grand Wagoneer’s 6.4-liter V-8.

The all-wheel-drive, six-cylinder 2022 Grand Wagoneer gets 14 mpg in the city and 20 mpg on the interstate for 17 mpg.

This is significantly better than the 6.4-liter V-8, which gets 13 mpg in the city and 18 mpg on the interstate for 15 mpg.

The Hurricane will be offered in the Wagoneer starting in 2023, replacing the present 5.7-liter V-8 engine.

The 5.7-liter engine achieves virtually the same fuel economy as the Grand Wagoneer six-cylinder, with 15 mpg on urban streets and 20 mpg on the highway, 17 mpg combined.

It’s worth mentioning that this is a comparison of the high-output Hurricane; the 420-hp standard-output version, which will be available next year, may provide better results.

The Wagoneer is also available with rear-wheel drive, and regardless of power output, the six-cylinder will likely deliver even better fuel economy.

The 6-cylinder will be the only engine available in the Grand Wagoneer L and Wagoneer L, introduced in 2023.

The added length and weight will almost certainly reduce fuel economy.

For the time being, the new inline-six is only available in the top-spec 2022 Grand Wagoneer, making it the potent engine in the lineup.

It costs $2000 more than the 471-hp V-8, and dealerships are presently taking orders.
