With the automotive industry switching to electric powertrains, car enthusiasts will rarely see a new gasoline engine, but Sterantis unveiled its new "Hurricane" GME-T6 twin-turbo 3.0-liter inline 6-cylinder engine early Friday morning.

Three versions will be built, and Sterantis announced specs for the H.O. (high output) and S.O. (standard output) versions; the H.O. version will debut at the Grand Wagoner at the New York International Auto Show in April, with the market The H.O. version is scheduled to debut at the New York International Auto Show in April, and will be introduced to the market later this year.

I noticed that it is listed as a $2,000 option above the standard 471-horsepower 6.4-liter V-8 engine. According to the site, this engine was listed as an option on all four versions of the Grand Wagoneer, but was not mentioned as an option on the Wagoneer with the 392-horsepower 5.7-liter V-8. The option was subsequently removed from the configurator.

Jeep lists the H.O. version as producing over 500 hp and 475 lb-ft of torque. The dual overhead cam aluminum block engine has a 9.5:1 compression ratio, direct injection, and variable valve timing. Redline is 6,100 rpm, and the turbo is capable of producing 26 psi of boost, with 90% of peak torque reaching 2,350 rpm, according to Sterantis. Sterantis explains that the two smaller turbos spin faster than the one larger turbo and can deliver boost to the engine at lower rpm. Cooling for the Hurricane is provided by an engine-mounted water-cooled charge cooler with a dedicated cooling circuit and dual water-cooled exhaust manifolds built into the cylinder head.

The H.O. version runs on premium fuel, while the S.O. recommends premium fuel. Both are equipped with stop-start technology, but EPA fuel economy has not yet been determined. According to Sterantis, the H.O. version uses less gasoline and produces fewer emissions (up to 15% more efficient) than the larger engine, a standard 6.4-liter V-8. [Sterantis aims to become the U.S. leader in electrification by achieving a 50% sales mix of battery electric vehicles (BEVs) by 2030. Sterantis aims to reduce emissions by 50% by 2030 and achieve net carbon zero by 2038.

An S.O. version with 22.4 psi peak boost, 400 hp and over 450 lb-ft of torque is expected in 2024, as is a hybrid version with even more power than the H.O. version.

According to Sterantis, the Hurricane shares bore, stroke, and bore spacing with the company's 2.0-liter turbo four. It will be used on the company's STLA Large and STLA Frame platforms. In addition to the Grand Wagoneer, the engine is expected to be used in the Jeep Grand Cherokee, Ram 1500, and the next-generation Dodge Charger and Challenger.

The engine will be produced at the Saltillo North Engine Plant in Mexico.
