Jeep Grand Cherokee Reportedly Gaining 420-HP Hurricane Inline-6 for Model Year 2028Road & TrackJoe KucinskiMon, September 21, 2026 at 5:33 PM UTCAdd us on GoogleJeep Bringing I-6 to Grand Cherokee: ReportStellantisThe beloved Hemi V-8 may not be coming back to the Jeep Grand Cherokee, but a potential replacement could make the loss a little easier to accept. According to a new report from MoparInsiders, Jeep is preparing to put the 3.0-liter twin-turbo Hurricane inline-six into the Grand Cherokee for the 2028 model year. It might not make those lovely V-8 sounds, but it could make more than 400 horsepower.The report claims that a well-placed source and a leaked document point toward the Standard Output (S.O.) version of the Hurricane I-6 as seen in the Dodge Charger R/T Sixpack, rather than the more powerful High Output variant found in the likes of the Scat Pack Sixpack. The S.O. twin-turbo Hurricane in the current Jeep Grand Wagoneer, for example, brings 468 pound-feet of torque with its 420 horsepower. That would represent a significant bump in power compared to the 2.0-liter turbocharged Hurricane 4-cylinder that, with 324 horsepower and 332 pound-feet of torque, is currently the most powerful engine in the Grand Cherokee lineup.In fact, the S.O. Hurricane I6 would even be more powerful than the 5.7-liter V-8 last offered in the Grand Cherokee in 2023. That Hemi was good for 357 horsepower and 390 pound-feet of torque. (Road & Track reached out to Jeep in regards to this report, but the company said it wouldn't comment on the matter.)AdvertisementAdvertisementMore power is always good ... but why not put the Hemi back under the hood of the Grand Cherokee? After all, it's already been restored to other Stellantis products such as the Ram 1500. Well, it seems to be a matter of positioning; Stellantis head of American brands Tim Kuniskis said earlier this year to The Drive that returning the 5.7-liter V-8 to the Grand Cherokee "doesn't make sense."A twin-turbo inline-six won't deliver the sound or character of a Hemi. But with a likely 420 hp and 468 pound-feet of torque, such an engine could still deliver more power for better acceleration and a higher towing capacity. For Grand Cherokee buyers who have been waiting for some muscle to return, that's not a bad consolation prize.You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
