Stellantis today revealed its new, 3.0-liter, twin-turbo, inline, six-cylinder engine, named Hurricane, that delivers better fuel economy and fewer emissions than larger engines while at the same time generates more horsepower and torque than many competitors’ naturally aspirated V-8 and boosted six-cylinder power plants.

Designed with an inherently smooth-running I-6 configuration and state-of-the-art technology, the Hurricane twin-turbo’s robust base architecture enables Stellantis propulsion systems engineers to create two distinct variants:

Optimized for fuel economy, including the use of cooled exhaust gas circulation, while delivering enhanced power and torque (more than 400 hp/450 lb.-ft. of torque).

High Output (HO): Optimized for great performance (more than 500 hp/475 lb.-ft.) while maintaining significant fuel economy during heavy use, such as towing.

The Hurricane twin-turbo achieves this V-8-rivaling performance while being up to 15% more efficient than larger engines.

“As Stellantis aims to become the U.S. leader in electrification, with a 50% battery-electric vehicle (BEV) sales mix by 2030, internal combustion engines will play a key role in our portfolio for years to come and we owe it to our customers and the environment to provide the cleanest, most efficient propulsion possible,” said Micky Bly, Stellantis head of propulsion systems. “The Hurricane twin-turbo is a no-compromise engine that delivers better fuel economy and an important reduction in greenhouse gases without asking our customers to give up performance.”

Reducing greenhouse gas emissions is one part of Stellantis’ commitment to cut its carbon footprint by 50% by 2030 and to lead the transportation industry by achieving Net Carbon Zero by 2038. Those goals are key elements of the Stellantis Dare Forward 2030 strategic plan.

The Hurricane twin-turbo flexes its muscle with a broad, flat torque band that sees the engine maintain at least 90% of peak torque from 2,350 rpm all the way to its red line.

Specific horsepower and torque ratings will vary based on vehicle. The first vehicles powered by the Hurricane twin-turbo I-6 reach dealership showrooms this year.

The foundation of the Hurricane twin-turbo is a deep-skirt cast-aluminum block with a structural aluminum alloy oil pan. Cross-bolted steel main bearing caps contain the strong rotating assembly of a forged steel crankshaft and forged steel connecting rods. During manufacturing the block is deck-plate honed to optimize the cylinder bore shape, which helps improve fuel efficiency.
