The engine will provide more pep than the current Pentastar V-6 and Hurricane inline-four, boosting the SUV’s towing capacity.
The Jeep Grand Cherokee got a new engine for 2026, but it wasn’t the one everyone wanted. The new Hurricane inline-four produces a punchy 324 horsepower, but it lacks refinement. Now, the Grand Cherokee is set to get another new powertrain, and while the V-8 is still missing, the rumored arrival of the Hurricane inline-six promises the smooth delivery of even more muscle.
The report of a Hurricane inline-six-powered Grand Cherokee comes via Moparinsiders.com, which says its sources claim the new engine is coming for the 2028 model year. The Grand Cherokee will reportedly feature the standard-output version of the twin-turbocharged 3.0-liter six-cylinder, and not the high-output configuration. We’ve reached out to Jeep and will update this story if we hear back.
The standard-output Hurricane produces 420 horsepower and 468 pound-feet of torque in other Stellantis products, while the high-output variant is good for 550 hp and 531 pound-feet. The new six-cylinder engine could fill a gap in the lineup that has been missing since Jeep stopped offering the Hemi 5.7-liter V-8 in the Grand Cherokee; it would out-punch the V-8’s 360 horsepower and 390 pound-feet. The six-cylinder would also likely give the SUV more towing capability, which currently maxes out at 6200 pounds with the four-cylinder.
Sadly, it seems like a V-8 may not be returning in the Grand Cherokee, at least not without an SRT badge. 7-liter Hemi back in the Grand Cherokee, with the automaker aiming to differentiate the personality between the Jeep SUV and the Dodge Durango .
