In these days when the automotive conversation revolves around electric cars and powertrains, the European automotive conglomerate Stellantis has just made a peculiar announcement: the launch of an all-new gasoline engine. Following the lead of manufacturers such as Mercedes-Benz and BMW, Stellantis has just announced a new 3.0-litre twin-turbo inline-six engine they call hurricanewhich in the United States could herald the eventual retirement of the Hemi family of V8s introduced in 2003.
According to Stellantis, the Hurricane engine “delivers better fuel economy and lower emissions than larger engines, while generating more horsepower and torque than its competitors’ naturally aspirated V-8s and beefed-up six-cylinder.”
The new Hurricane engine will initially arrive in two configurations, standard delivery (SO) optimized for fuel economy, thanks to the use of cooled exhaust gas recirculation technology, generating a not inconsiderable amount of power estimated at 400 horsepower and 450 lb-ft of torque, and high performance (HO) calibrated to generate more than 500 horsepower and 475 lb-ft of torque, which according to Stellantis“is capable of maintaining acceptable fuel economy during heavy use such as towing operations” and adds that the “The twin-turbo Hurricane achieves performance that rivals that of a V-8, but is up to 15% more efficient.”
The 3.0-liter twin-turbocharged Hurricane I-6 was developed over three years at the company’s technical center in Auburn Hills, Michigan, by what is now known as the US arm of Stellantis, but was until recently the Chrysler side of Fiat. Chrysler Automobiles. Its design shares elements with the 2.0-liter turbocharged 4-cylinder found under the hood of the Jeep Wrangler, Wrangler 4xe, Cherokee and the recently launched Grand Cherokee 4xe, and will be built alongside the Hemi at the Stellantis engine plant. in Saltillo Norte, Mexico, which will be able to build up to 250,000 Hurricanes a year if necessary.
Final Hurricane horsepower and torque figures will vary depending on the vehicle using it. The first Hurricane I-6 twin-turbo powered vehicles arrive in dealerships this year, but Stellantis has yet to say what the inaugural models will be.
