Jeep, Dodge, Ram to get a new Stellantis Turbo Inline-Six engine

  • Stellanti’s all-new dual-turbocharged 3.0-liter inline six, called the Hurricane, should look under the hood of various models for the 2023 model, potentially from the Jeep Wrangler to the Ram 1500 and the Dodge Charger and Challenger.
  • It will be offered in standard and high-power variants, and it will fit into all vehicles currently sold that have a longitudinal engine.
  • Production has already begun at Stellanti’s engine plant in Saltillo South, Mexico.

    From battery technology to powerful compact electric motors, headlines about electrification seem to be burning all these days. Although we have an undeniable interest in the future of electrified propulsion systems, the technical feat of a clean internal combustion engine is a breath of fresh air. Although other automakers have ambitious goals to become fully electric by 2030, Stellantis has identified the need for gasoline-powered engines in the future, and the company’s goal of being 50 percent electrified in North America by then seems more realistic. Enter the Hurricane: a two-turbocharged 3.0-liter inline six.

    The new power plant will fit into all vehicles currently on sale that have a longitudinal engine. When the Hurricane arrives under the hood of various Stellantis-branded vehicles within the next year, the dual overhead camshaft, direct-injected inline six, will have drilling and impact dimensions of 84.0 millimeters and 90.0 millimeters. The block and cylinder head are constructed of aluminum and its cylinders are spray-drilled using a plasma transfer wire arc process that adds a thin iron coating to the cylinder walls, which Stellantis claims saves three pounds compared to using a more traditional iron sleeve. These figures for drilling and stroke are identical to BMW’s potent S58 3.0-liter inline six, which drives the M brand and which also follows the same approach of having each turbo powered by three cylinders to minimize turbo delay. Hurricane will be offered in standard and high power variants.

    StellantisCar and driver

    Stellantis says the standard-power engine will deliver more than 400 horsepower and a torque of 450 pounds, with the final power figures determined by the individual brands using the new mill. The less powerful version has a compression ratio of 10.4: 1, and its intake charge is pressurized by the dual turbos with up to 22.4 pounds boost before being cooled by a water-to-air intercooler. Junior 3.0-liter speed to 5800 rpm and runs on 87 octane, although 91 is recommended.

    The high-power version is set to deliver more than 500 horsepower and 475 pound-feet of torque, making it on par with BMW’s strongest six-cylinder offering. The compression ratio is lowered to 9.5: 1 to accommodate the 26.0 psi delivered from the larger turbos through a dual inlet. The high-power engine has its own cylinder head, crankshaft, larger water-to-air intercooler and forged aluminum pistons (against the cast parts of the standard power) and will rev slightly higher, to 6100 rpm, even if it is far from the glorious. 7200 rpm jam of BMW’s singing sex. To generate all this wonderful power, 91 octane will be required.

    These engines could be used for a number of Stellantis products such as the Jeep Gladiator, Grand Cherokee, Wagoneer, Grand Wagoneer and Wrangler; Frames 1500 and 2500; and Dodge Challenger and Charger. If we were to speculate, we would say that the new inline six will replace the classic – albeit very inefficient – V-8s we have grown to love and the venerable Pentastar 3.6-liter V-6: but Stellantis declined to say just that. Still, we are happy to get our hands on the hurricane in the coming months.
